//[END OF VERSION]
K.O.L. - is a set of objects to create small programs
with the Delphi, but without the VCL. KOL allows to
create executables of size about 10 times smaller then
those created with the VCL. But this does not mean that
KOL is less power then the VCL - perhaps just the opposite...
KOL is provided free with the source code.

Please note, that KOL does not use keyword 'class'. Instead,
poor Pascal 'object' is the base of our objects. So, remember,
how we worked earlier with such Object Pascal's objects:
|<br>
- to create objects dynamically, use P<objname> instead of
T<objname> to allocate a pointer for dynamically created
object instance;
|<br>
- remember, that constructors of objects can not be virtual.
Override procedure Init instead in your own derived objects;
|<br>
- rather then call constructors of objects, call global procedures
New<objname> (e.g. NewLabel). If not, first (for virtualally
created objects) call New( ); then call constructor Create
(which calls Init) - but this is possible only if the constructor
is overriden by a new one.
|<br>
- the operator 'is' is not applicable to objects. And operator 'as'
is not necessary (and is not applicable too), use typecast to desired
object type, e.g.: "PSomeObjectType( C )" inplace of "C as TSomeClassType".
|<br>
|<hr>
Also remember, that IF [ MyObj: PMyObj ] THEN
NOT[ with MyObj do ] BUT[ with MyObj^ do ]
Though it is possible to skip '^' symbol when accessing member
fields, methods, properties, e.g. [ MyObj.Execute; ]

Following conditional symbols can be used in a project
(Project | Options | Directories/Conditional Defines)
to change code generated a bit. There are following:
|<pre>
EXTERNAL_KOLDEFS - since there are a lot of such symbols, it may be not
possible to include all the desired optional symbols
in the Project Options (Delphi has a restriction to 256
characters in a semicolon-separated list of included
options). This symbol allows to exceed this restriction:
you place your defines in an included file
EXTERNAL_DEFINES.INC, located in your project directory.
Since this is a normal pascal source, use usual Pascal
syntax: add a directive (*$DEFINE symbol*) for each
symbol you want, and you can decorate it with usual
comments if necessary.
ENABLE_DEPRECATED - some old declaration made "deprecated" and moved to
KOL_deprecated.inc. This symbol provides including
such declarations into KOL.pas and makes it available
again.
DISABLE_DEPRECATED - (default) - disables deprecated declaration.
WIN - (default) - version for Windows.
LINUX - version for Linux (only PAS_VERSION) -- not yet ready
When not defined, symbol WIN is defined automatically.
LINUX_USE_HOME_STARTFDIR - in Linux app, HOME directory of the user will be
returned by GetStartDir function.
GTK - version for GTK (Linux or Win32) -- not yet ready
XQT - version for QT (Linux or Win32) -- not yet ready
FPC - Free Pascal version. KOL can be used with such compiler
to create Win32 applications. To create Win-CE
applications (with FPC compiler)), use the separate
version of KOL specially designed for it.
INPACKAGE - version for Mirror Classes Library package (design-time
only). This option should be included only in MCK package
options and never in options of the KOL/MCK application.
PAS_VERSION - to use Pascal version of the code.
PARANOIA - to force short versions of asm instructions (for D5
and below, D6 and higher use those instructions always).
USE_CMOV - force using CMOV machine instruction in asm code (not
recommended, still on some machines your application
will not work).
SMALLEST_CODE - to create minimal code application (affected:
(o) SimpleGetCtlBrushHandle - returns solid silver brush
always;
(o) _NewWindowed
- only default system font used by default;
font of the parent control is not applied to its
children automatically (but see SMALLEST_CODE_PARENTFONT);
- fBrush always set to NIL by default (parent Brush
is not applied);
(o) WndProcDoEraseBkgnd
- child controls windows are not created in WM_ERASEBKGND
if were not created earlier (in most case, all OK
with this - controls are created BTW);
- SetBkColor, SetBkMode, SetBrushOrgEx are not
called (all OK therefore)
(o) by default, NOT_UNLOAD_RICHEDITLIB is defined if
UNLOAD_RICHEDITLIB is not defined in project options
(this minimizes finalization section).
(o) _NewControl
- BoundsRect initialized with a rectangle
(aParent.fMarginLeft, aParent.fMarginTop,
aParent.fMarginLeft+64, aParent.fMargin+64)
rather then with (aParent.fMargin+aParent.fMarginLeft,
aParent.fMargin+aParent.fMarginTop,
aParent.fMargin+aParent.fMarginLeft+64,
aParent.fMargin+aParent.fMarginTop+64).
In most cases this is enough.
(o) Int2Hex
there are no check for second perameter > 15
(o) .... other see in code
SMALLER_CODE - like smallest code, but fuctionality is the same.
The speed can be lower therefore.
SMALLEST_CODE_PARENTFONT - Parent font therefore is applied for child controls,
but initially only.
NOT_USE_KOLMATH - Only for _X_ (GTK + Linux): to prevent referencing
KOLmath in uses. This makes method TCanvas.Arc
unavailable, but the application become smaller.
NOT_USE_EXCEPTIONS - to prevent referencing unit ERR.PAS in uses even when
KOLmath is listed there.
REDEFINE_ABS - usual Abs works as a macro which is better in most
cases. But who knows...
CUSTOM_APPICON - when this option is defined, the resource name for the
application icon is extracted from a file
CusomAppIconRsrcName_PAS.inc (place it in your project
folder and type there name of the recource in qutations).
By default, string 'MAIN' is used like in usual Delphi
application.
USE_NAMES - to use property Name with any TObj. This makes also
available method TObj.FindObj( name ): PObj.
UNIQUE_NAMES - provide Name property to be unique among all siblings.
USE_MHTOOLTIP - to use KOLMHTOOLTIP.pas (actually it is not a separate
unit but a set of portions of code included into KOL.pas
in different places). This unit provides tooltips (hints)
for arbitrary controls which appear when mouse is over
such controls.
USE_GRUSH - to use ToGRush.pas unit, which provides automatic
redirection of the most cintrols creation functions
to the KOLGRushControls.pas.
(USE_CONSTRUCTORS - to use constructors like in VCL. Note: this option is
not carefully tested!)
TLIST_FAST - very fast implementation of TList (for coast of some
additional code).
DFLT_TLIST_NOUSE_BLOCKS - for TLIST_FAST: by default, do not make all TList
objects using new (fast) algoritms, but only those of
TList objects, which property UseBlocks was set to
TRUE after creating it.
STREAM_LARGE64 - turns on support of streams (and files) of size larger
then 4 Gbytes. Data type Int64 used for parameters of
the most of methods and functions in such case. (Note:
Int64 was introduced since Delphi5, so in earlier Delphi
versions using this symbol is not possible).
STREAM_COMPAT - still STREAM_LARGE64 appeared (in v2.84), most of
methods and functions declarations became incompatible
with earlier created extensions. This symbol provides
compatibility for such extensions, but it desables
using large streams.
OLD_STREAM_CAPACITY - to use elder TStream.SetCapacity algorithm (it did not
make Capacity smaller than already achieved, but in
newer version, Capacity can be set to a smaller value,
and for memory streams, rest of memory is freeing in
such case).
OLD_MEMSTREAMS_SETSIZE - to use elder TStream.SetSize for memory streams. In
a new version, setting new size also changes Capacity
to the same value (in earlier case, a value for
Capacity property was calculated to become a bit
greater then a value set for Size property).
OLD_COMPAT - to use symbol ';' as a file list separator (all operations
using DoFileOp function such as DeleteFile2Recycle and
CopyMoveFiles).
OLD_REGKEYGETSUBKEYS - to use elder version of RegKeyGetSubKeys functions
(new version is faster).
OLD_REGKEYGETVALUENAMES - to use elder version of RegKeyGetValueNames
(newer version is faster).
USE_CUSTOMEXTENSIONS - to extend TControl with custom additions.
UNICODE_CTRLS - to use Unicode versions of controls (WM_XXXXW messages,
etc.)
SAFE_CODE - use more safe code in some algorithms (but more slowly
and taking more code a bit).
USE_OnIdle - to use OnIdle event
SNAPMOUSE2DFLTBTN - for all MessageBox-based functions, snap mouse to
default button is provided if such option is on in
mouse driver settings.
BUTTON_DBLCLICK - to prevent clicking buttons with double click (separate
event OnMouseDblClk is fired in such case), this takes
smaller code but buttons can not be pressed with mouse
fast. When SMALLEST_CODE on, this option also is on.
ALL_BUTTONS_RESPOND_TO_ENTER - obvious (by default, buttons respond to key
SPACE, since those are working this way in Windows).
CLICK_DEFAULT_CANCEL_BTN_DIRECTLY - to prevent visual effect of default/cancel
button pressing with Enter/Escape keys. Also, button
don't become focused in such case.
DEFAULT_CANCEL_BTN_EXCLUSIVE - to disable assigning to a button properties
DefaultBtn and CancelBtn simultaneously.
NO_DEFAULT_BUTTON_BOLD - to prevent DefaultBtn to be visually with
a bold border.
BITBTN_DISABLEDGLYPH2 - to restore old behaviour of multi-glyph bitbtn, when
index 2 was used to represent the button in disabled
state, and glyph with index 1 was used forpressed dtate.
Now by default index 1 corresponds to the disabled state,
and index 2 to the pressed state, i.e. these are swapped.
ESC_CLOSE_DIALOGS - to allow closing all dialogs with ESCAPE.
KEY_PREVIEW - form also receive WM_KEYDOWN (OnKeyDown event fired)
SUPPORT_ONDEADCHAR - to support OnKeyDeadChar event in responce to
WM_DEADCHAR, WM_SYSDEADCHAR
OpenSaveDialog_Extended - to allow using custom extensions for OpenSaveDialog.
AUTO_CONTEXT_HELP - to use automatic respond to WM_CONTEXTMENU to call
context help.
NOT_FIX_CURINDEX - to use old version of TControl.SetItems, which could
lead to loose CurIndex value (e.g. for Combobox)
NOT_FIX_MODAL - not to fix modal (if fixed, click on any window
activates the application. If not fixed, code is
smaller very a little, but only click on modal form
activates the application). This does not fix calling
MsgBox though.
MODAL_ACTIVATE_FIX - if this option is set, all the windows of clicked app
with active modal form are brought to foreground, not
only modal form itself. This option is not necessary if
only two forms are visible at a time (the main form and
the active modal form).
NEW_MODAL - to use extended modalness.
USE_SETMODALRESULT - to guarantee ModalResult property assigning handling.
USE_SHOWMODALPARENTED_ALWAYS - to use TControl.ShowModalParented( Applet )
instead of TControl.ShowModal always.
USE_MENU_CURCTL - to use CurCtl property in popup menu to detect which
control initiated a pop-up.
NEW_MENU_ACCELL - to use new menu accelerators handling, without
AcceleratorTable (not tested for all cases)
USE_DROPDOWNCOUNT - to force setting combobox dropdown count.
NOT_UNLOAD_RICHEDITLIB - to stop unload Rich Edit library in finalization
section (to economy several byte of code).
NOT_USE_RICHEDIT - not use richedit (it will not be possible to create richedit)
TV_DRAG_RBUTTON - to allow dragging tree view items with right mouse
button too.
TOOLBAR_FORCE_CHILDALIGN - this option provides Align working for child
controls of the toolbar control, but when with this option
is turned on it is impossible to have neighbour controls
on a form correctly aligned. This last disadvantage is
not important if a toolbar is always placed on a separate
panel-like control as a child.
Note: this option has no effect for Win9x, still use of
it under Win9x can crash the application!!!
TOOLBAR_DOT_NOAUTOSIZE_BUTTON - this option forces prefix dot character in
button caption to be treated as an instruction to
remove TBSTYLE_AUTOSIZE from the button style. Actually,
this feature not necessary still custom button size can
be set even if such style is on for a button.
CANRESIZE_THICKFRAME - to use elder version of CanResize, changing border
style of the window (this cause incorrect form view in
Vista Aero theme (due a bug in Vista?)).
ANCHORS_WM_SIZE - to check WM_SIZE message in Anchor handling window
procedure. By default, now used WM_WINDOWPOSCHANGED.
USE_PROP - to use GetProp / SetProp (old style) in place of
Get / SetWindowLong( wnd, GWL_USERDATA... ) (slower?)
PROVIDE_EXITCODE - PostQuitMessage( value ) assigns value to ExitCode
INITIALFORMSIZE_FIXMENU - form size initially is really the same as defined at
design time even for forms having main menu bar
USE_GRAPHCTLS - to use graphic (non-windowed) controls
RICHEDIT_XPBORDER - provide correct drawing rich edit control border with
XP themes.
GRAPHCTL_XPSTYLES - to use XP themed Visual styles for drawing graphic
controls. This does not affect windowed controls
which visual style is controlled by the manifest.
This option also turns on RICHEDIT_XPBORDER option.
GRAPHCTL_HOTTRACK - to use hot-tracking also together with XP themed
graphic controls (otherwise only static XP themed
view is provided). Also, turn this option on if you
want to handle OnMouseEnter and OnMouseLeabe events
for graphic controls.
NEW_OPEN_DIR_STYLE_EX - to use new code for TOpenDirDialog, which provides
correct working of the dialog with an option
odNewDialogStyle set (even in Windows 9x system).
HTMLHELP_NOTOP - when Html help is called, its window become a child of
the desktop, not application (in such case it is not
closed together with the application, and it is apper
not on top of the application).
ICON_DIFF_WH - to support icons having Width <> Height
ICONLOAD_PRESERVEBMPS - when an icon is loaded, its bitmap and mask are
extracted and in case when such symbol is defined,
these one or two bitmaps are preserved until TIcon
object is destroyed.
LOADEX - to use TBitmap.LoadFromStreamEx while loading icon
from a stream or a file.
USE_OLDCONVERT2MASK - to use elder Convert2Mask method (newer is more correct).
FIX_TRANSPBMPPALETTE - for TBitmap.StretchDrawMasked, bitmaps with PixelFormat
= pf4bit or pf8bit are first converted (in a temporary
TBitmap object) to pf32bit, and then are drawn. This
fixes problems with palette usage for such DIB bitmaps.
FILL_BROKEN_BITMAP - TBitmap.LoadFromStreamEx: broken bitmaps rest of
scanlines are be filled with zeroes (usually black color)
rather then left containing trash memory bits.
AUTO_REPLACE_CLEARTYPE- to replace automatically CLEARTYPE_QUALITY fonts
with ANTIALIASED_QUALITY when running under elder
Windows version than XP.
FORCE_ALTERNATEFILENAME- TDirList.ScanDirectoryFORCE_ALTERNATEFILENAME - forced
using an alternate file path and filename for unicode
paths (ïðèíóäèòåëüíîå èñïîëüçîâàíèå àëüòåðíàòèâíîãî èìåíè
ïóòè è èìåíè ôàéëà äëÿ þíèêîä ïóòåé)
NEW_GRADIENT - to use new gradient painting by homm (fast).
OLD_ALIGN - to prevent using new Align by Galkov.
NEW_ALIGN - (default) - to use new Align implementation (faster).
OLD_TRANSPARENT - to prevent using NEW_TRANSPARENT
NEW_TRANSPARENT - created by Alexander Karpinsky a.k.a. homm (faster)
SBOX_OLDPOS - to use elder formulas to calculate scroll box positions
(just for compatibility with very old apps using it).
OLD_REFCOUNT - to prevent using new RefInc / RefDec behaviour
(new style of using RefCount works better).
OLD_FREE - to declare Free as a method as in earlier versions of KOL.
In new versions, Free is declared as a property, and
"calling" it just redirects call to RefDec. OLD_FREE
can be used for compatibility with compilers not
understanding "calling" a property without assigning
something to or from it (Turbo Delphi?).
FILE_EXISTS_EX - to use more correct (but a bit large code in FileExists functon)
USE_AUTOFREE4CONTROLS - (default) - from 2.40, most of control sub-objects are
destroying using Add2AutoFree (smaller code).
NOT_USE_AUTOFREE4CONTROLS - this option returns to previous behaviour (just to
compare code size). Will be deprecated in future.
ENDSESSION_HALT - to halt the process when WM_ENDSESSION comes.
FILESTREAM_POSITION - in PAS_VERSION, Stream..fData.fPosition always show
current position (for debug purposes)
PSEUDO_THREADS - to use pseudo-threads instead of normal threads.
WAIT_SLEEP - for PSEUDO_THREADS: sleep 10 ms in a
WaitForMultipleObjects loop.
ENUM_DYN_HANDLERS_AFTER_RUN - to allow all the events handling even when
AppletTerminated become TRUE.
STOP_WNDPROCTRANSPARENT_AFTER_APPLETTERMINATED - use this long-named otpion to
prevent any functionality of WndProcTransparent after
AppletTerminated is set to true.
STOPTIMER_AFTER_APPLETTERMINATED - use this symbol to prevent timer event
firing after setting AppletTerminated to TRUE.
TIMER_APPLETWND - to use Applet window to handle WM_TIMER events
(otherwise special single invisible window is created
to handle such events).
SUPPORT_LONG_TIMER - LINUX only: set this option if TTimer.Interval can be
set to a value greater then 1,800,000 (30 minutes).
DEBUG_MENU - to debug menu.
DEBUG_GDIOBJECTS - to allow counting all the GDI objects used.
CHK_BITBLT - to check BitBlt operations.
DEBUG_ENDSESSION - to allow debugging WM_ENDSESSION handling.
DEBUG_CREATEWINDOW - to debug CreateWindow.
CRASH_DEBUG - to fill object memory with $DD before freeing it
(program really crashes when the object is
attempted to destroy more then once and in most
cases when a destroyed object is accessed after the
destruction).
DEBUG_MCK - specially designed to debug Mirror Classes Kit.
DEBUG - other debugging.
EXTERNAL_DEFINES - if count of options necessary to set is very large
Delphi ignores past of those. To avoid this problem,
set only this option in Project's options, and place
all other options to ExternalDefines.inc file as a
sequence of {$DEFINE ... directives.
But note, such file should be located in a
project directory, but not in the directory where KOL.pas
is located. This is enough to provide different sets
of defines for each project.

This makes code more safe from intersecting flows of processing,
where some code want to destroy object, but others suppose that it

If You want to release object at the end of block RefInc..RefDec,
do it immediately BEFORE call of last RefDec (to avoid situation,
when object is released in result of RefDec, and attempt to
destroy it follow leads to AV exception).

any sensible value. It is declared as a function for internal

event. }

to write out of top bound given by Size (i.e. memory can not be resized,
or reallocated. When stream object is destroyed this memory is not freed. }
function NewConcatStream( Stream1, Stream2: PStream ): PStream;
{* Creates a stream which is a concatenation of two source stream. After
the call, both source streams are belonging to the resulting stream and these
will be destroyed together with the resulting stream. (So forget about it).
After the call, first stream will not be changed in size via methods of
concatenated stream (and it is not recommended to use further Stream1 and
Stream2 methods too). But Stream2 can still be increased, if it allows doing
so when some data are appended or Size of resulting stream is changed (but
not less then Stream1.Size).
Nature and physical location of Stream1 and Stream2 are not important and
can be absolutely different. But it is supposed that both streams are not
compressed and its Size is known always and Seek operation is valid.
This function accepts recursive (multi-level) usage: resulting concatenation
stream can be used as a left or right parameter to create another concatenation
stream later, so it is possible to build a tree of streams concatenated,
concatenating this way several different streams and use it as a single
data streaming object.
}
function NewSubStream( BaseStream: PStream; const FromPos, Size: TStrmSize ): PStream;
{* Creates a stream which is a subpart of BaseStream passes, starting from
FromPos and with given Size. Like in function NewConcatStream, passes
BaseStream become owned by newly created sub-stream object, and will be
destroyed automatically together with a sub-stream.
If you want to provide more long life time for a base stream (e.g. if you
plan to use it after a sub-stream based on it is destroyed), use method
RefInc for base stream once to prevent it from destroying when the sub-stream
is destroyed.
Note: be careful and avoid direct calling methods and properties of the base
stream, while you have a sub-stream created on base it, since the sub-stream
actually redirects all the requests to the parent base stream.
Sub-stream accepts setting Size to greater value later, and if some data
are written to it, it is written actually to the base stream, and when it
is written beyond the end position, this will increase size of the base
stream too (and if it is a file stream, this also will increase size of the
file on which the base stream was created).
This function accepts recursive (multi-level) usage: it is possible to create
later another sub-stream on base of existing sub-stream, still it is actully
can be treated as usual stream.

//[TCanvas DEFINITION]
TCanvas = object( TObj )
{* Very similar to VCL's TCanvas object. But with some changes, specific
for KOL: there is no necessary to use canvases in all applications.
And graphic tools objects are not created with canvas, but only
if really accessed in program. (Actually, even if paint box used,
only programmer decides, if to implement painting using Canvas or
to call low level API drawing functions working directly with DC).
Therefore TCanvas has some powerful extensions: rotated text support,
geometric pen support - just by changing correspondent properties
of certain graphic tool objects (Font.FontOrientation, Pen.GeometricPen).

Note, that it is better not to align combobox caClient, caLeft or
caRight (better way is to place a panel with Border = 0 and
EdgeStyle = esNone, align it as desired and to place a combobox on it
aligning caTop or caBottom). Otherwise, big problems could be under
Win9x/Me, and some delay could occur under any other systems.

|<br>
To use a form as a modal, it is possible to make it either auto-created
or dynamically created. For a first case, You (may be prefer to hide a
form after showing it as a modal:
!
! procedure TForm1.Button1Click( Sender: PObj );
! begin
! Form2.Form.ShowModal;
! Form2.Form.Hide;
! end;
!
Another way is to create modal form just before showing it (this economies
system resources):
!
! procedure TForm1.Button1Click( Sender: PObj );
! begin
! NewForm2( Form2, Applet );
! Form2.Form.ShowModal;
! Form2.Form.Free; // Never call Form2.Free or Form2.Form.Close
! end; // but always Form2.Form.Free; (!)
!
In samples above, You certainly can place any wished code before and after
calling ShowModal method.
|<br>
Do not forget that if You have more than a single form in your project,
separate Applet object should be used.

{* Call this method for a form or control to drag it with left mouse button,
when mouse left button is already down. Dragging is stopped when left mouse
button is released. See also DragStartEx, DragStopEx. }
procedure DragStartEx;
{* Call this method to start dragging the form by mouse. To stop
dragging, call DragStopEx method. (Tip: to detect mouse up event,
use OnMouseUp event of the dragging control). This method can be used
to move any control with the mouse, not only entire form. State of
mouse button is not significant. Determine dragging state of the control
checking its Dragging property. }
procedure DragStopEx;
{* Call this method to stop dragging the form (started by DragStopEx). }

flag is set. (Applicable to the GDK and other Linux systems). }
property OnMouseWheel: TOnMouse read fOnMouseWheel write SetOnMouseWheel;
{* Mouse wheel (up or down) event. In Windows, only focused controls and
controls having scrollbars (or a scrollbar iteself) receive such
message. To get direction and amount of wheel, use typecast:
SmallInt( HiWord( Mouse.Shift ) ). Value 120 corresponds to one wheel
step (-120 - for step back). }

Special event, which allows to extend OnMouseEnter / OnMouseLeave
(and also Flat property for BitBtn control). If a handler is assigned
to this event, actual testing whether mouse is in control or not,
is occuring in the handler. So, it is possible to simulate more
careful hot tracking for controls with non-rectangular shape (such
as glyphed BitBtn control). }
property MouseInControl: Boolean read fMouseInControl;

is set to True. Otherwise, False is returned always. }
property Flat: Boolean read fFlat write SetFlat;
{* |<#bitbtn>
Set it to True for BitBtn, to provide either flat border for a button
or availability of "highlighting" (correspondent to glyph index 4).
|<br>
Note: this can work incorrectly a bit under win95 without comctl32.dll
updated. Therefore, application will launch. To enforce correct working
even under Win95, use your own timer, which event handler checks for
mouse over bitbtn control, e.g.:
! procedure TForm1.Timer1Timer(Sender: PObj);
! var P: TPoint;
! begin
! if not BitBtn1.MouseInControl then Exit;

}
property RepeatInterval: Integer read fRepeatInterval write fRepeatInterval;
{* |<#bitbtn>
If this property is set to non-zero, it is interpreted (for BitBtn
only) as an interval in milliseconds between repeat button down events,
which are generated after first mouse or button click and until
button is released. Though, if the button is pressed with keyboard (with
space key), RepeatInterval value is ignored and frequency of repeatitive
clicking is determined by user keyboard settings only. }

{* Clears object content. Has different sense for different controls.
E.g., for label, editbox, button and other simple controls it
assigns empty string to Caption property. For listbox, combobox,
listview it deletes all items. For toolbar, it deletes all buttons.

{* |<#form>
Only for forms to set/retrieve status text to/from given status panel.
Panels are enumerated from 0 to 254, 255 is to indicate simple
status bar. Size grip in right bottom corner of status window is
displayed only if form still CanResize.
|<br>
When a status text is set first time, status bar window is created
(always aligned to bottom), and form is resizing to preset client height.
While status bar is showing, client height value is returned without
height of status bar. To remove status bar, call RemoveStatus method for
a form.
|<br>
By default, text is left-aligned within the specified part of a status
window. You can embed tab characters (#9) in the text to center or
right-align it. Text to the right of a single tab character is centered,
and text to the right of a second tab character is right-aligned.
|<br>
If You use separate status bar onto several panels, these automatically
align its widths to the same value (width divided to number of panels).
To adjust status panel widths for every panel, use property StatusPanelRightX.
}

! Progress1.Parent := Form1.StatusCtl;
(If you use MCK, code should be another a bit, and in this case it is
possible to create and adjust the control at design-time, and at run-time
change its parent control. E.g. (Progress1 is created at run-time here too):
! Progress1 := NewProgressBar( Form );
! Progress1.Parent := Form.StatusCtl;
).
Do not forget to provide StatusCtl to be existing first (e.g. assign
one-space string to SimpleStatusText property of the form, for MCK do
so using Object Inspector).
}

state for items or set checked state programmatically by changing
LVItemStateImgIdx[ ] property. Value 1 corresponds to unchecked state,
2 to checked. Value 0 allows to remove checkbox at all. So, to check all
added items by default (e.g.), do following:
! ListView1.LVItemStateImgIdx[ -1 ] := 2;
|<br>Use 1-based index of the image
in image list ImageListState. Value 0 reserved to use as "no state image".

of items in the list view control. }
//======== List View specific events:
property OnEndEditLVItem: TOnEditLVItem read fOnEndEditLVITem write SetOnEndEditLVItem;
{* |<#listview>
Called when edit of an item label in ListView control finished. Return
True to accept new label text, or false - to not accept it (item label
will not be changed). If handler not set to an event, all changes are
accepted. }
property OnLVDelete: TOnDeleteLVItem read fOnDeleteLVItem write SetOnDeleteLVItem;
{* |<#listview>
This event is called when an item is deleted in the listview.
Do not add, delete, or rearrange items in the list view while processing
this notification. }
property OnDeleteLVItem: TOnDeleteLVItem read fOnDeleteLVItem write SetOnDeleteLVItem;
{* |<#listview>
Called for every deleted list view item. }
property OnDeleteAllLVItems: TOnEvent read fOnDeleteAllLVItems write SetOnDeleteAllLVItems;
{* |<#listview>
Called when all the items of the list view control are to be deleted. If after
returning from this event handler event OnDeleteLVItem is yet assigned,
an event OnDeleteLVItem will be called for every deleted item. }
property OnLVData: TOnLVData read fOnLVData write SetOnLVData;
{* |<#listview>
Called to provide virtual list view with actual data. To use list view as
virtaul list view, define also lvsOwnerData style and set Count property
to actual row count of the list view. This manner of working with list view
control can greatly improve performance of an application when working with
huge data sets represented in listview control. }
property OnCompareLVItems: TOnCompareLVItems read fOnCompareLVItems write fOnCompareLVItems;
{* |<#listview>
Event to compare two list view items during sort operation (initiated by

{* |<#listview>
This event occure when an item or items range in list view control are
changing its state (e.g. selected or unselected). }
property OnDrawItem: TOnDrawItem read fOnDrawItem write SetOnDrawItem;
{* |<#listview>
|<#listbox>
|<#combo>
This event can be used to implement custom drawing for list view, list box, dropped
list of a combobox. For a list view, custom drawing using this event is possible
only in lvsDetail and lvsDetailNoHeader styles, and OnDrawItem is called to draw
entire row at once only. See also OnLVCustomDraw event. }
property OnLVCustomDraw: TOnLVCustomDraw read FOnLVCustomDraw write SetOnLVCustomDraw;
{* |<#listview>
Custom draw event for listview. For every item to be drawn, this event
can be called several times during a single drawing cycle - depending on
a result, returned by an event handler. Stage can have one of following
values:
|<pre>
CDDS_PREERASE
CDDS_POSTERASE
CDDS_ITEMPREERASE
CDDS_PREPAINT
CDDS_ITEMPREPAINT
CDDS_ITEM
CDDS_SUBITEM + CDDS_ITEMPREPAINT
CDDS_SUBITEM + CDDS_ITEMPOSTPAINT
CDDS_ITEMPOSTPAINT
CDDS_POSTPAINT
</pre>
When called, see on Stage to get know, on what stage the event is
activated. And depend on the stage and on what you want to paint,
return a value as a result, which instructs the system, if to use
default drawing on this (and follows) stage(s) for the item, and if
to notify further about different stages of drawing the item during
this drawing cycle. Possible values to return are:
|<pre>
CDRF_DODEFAULT - perform default drawing. Do not notify further for this
item (subitem) (or for entire listview, if called with
flag CDDS_ITEM reset - ?);
CDRF_NOTIFYITEMDRAW - return this value, when the event is called the
first time in a cycle of drawing, with ItemIdx = -1 and
flag CDDS_ITEM reset in Stage parameter;
CDRF_NOTIFYPOSTERASE - usually can be used to provide default erasing,
if you want to perform drawing immediately after that;
CDRF_NOTIFYPOSTPAINT - return this value to provide calling the event
after performing default drawing. Useful when you wish
redraw only a part of the (sub)item;
CDRF_SKIPDEFAULT - return this value to inform the system that all
drawing is done and system should not peform any more
drawing for the (sub)item during this drawing cycle.
CDRF_NEWFONT - informs the system, that font is changed and default
drawing should be performed with changed font;
|</pre>
If you want to get notifications for each subitem, do not use option
lvoOwnerDrawFixed, because such style prevents system from notifying
the application for each subitem to be drawn in the listview and only
notifications will be sent about entire items.

//======== Toolbar specific methods:
procedure TBAddBitmap( Bitmap: HBitmap );
{* |<#toolbar>
Adds bitmaps to a toolbar. You can pass special values as Bitmap to
add one of predefined system button images bitmaps:
|<br> THandle(-1) to add standard small icons,
|<br> THandle(-2) to add standard large icons,
|<br> THandle(-5) to add standard small view icons,
|<br> THandle(-6) to add standard large view icons,
|<br> THandle(-9) to add standard small history icons,
|<br> THandle(-10) to add standard large history icons,
(in that case use following values as indexes to the standard and view
bitmaps:
|<br>
STD_COPY, STD_CUT, STD_DELETE, STD_FILENEW, STD_FILEOPEN, STD_FILESAVE,
STD_FIND, STD_HELP, STD_PASTE, STD_PRINT, STD_PRINTPRE, STD_PROPERTIES,
STD_REDO, STD_REPLACE, STD_UNDO,
|<br>
VIEW_LARGEICONS, VIEW_SMALLICONS,
VIEW_LIST, VIEW_DETAILS, VIEW_SORTNAME, VIEW_SORTSIZE, VIEW_SORTDATE,
VIEW_SORTTYPE (use it as parameters BtnImgIdxArray in TBAddButtons or
TBInsertButtons methods, and in assigning value to TBButtonImage[ ]
property).
Added bitmaps have indeces starting from previous count of images
(as these are appended to existing - if any).
|<br>
Note, that if You add your own (custom) bitmap, it is not transparent.
Do not assume that clSilver is always equal to clBtnFace. Use API
function CreateMappedBitmap to load bitmap from resource and map
desired colors as you wish (e.g., convert clTeal to clBtnFace). Or,
call defined in KOL function LoadMappedBitmap to do the same more easy.
Unfortunately, resource identifier for bitmap to pass it to LoadMappedBitmap
or to CreateMappedBitmap seems must be integer, so it is necessary to
create rc-file manually and compile using Borland Resource Compiler to
figure it out. }
function TBAddButtons( const Buttons: array of PKOLChar; const BtnImgIdxArray: array
of Integer ): Integer;
{* |<#toolbar>
Adds buttons to toolbar. Last string in Buttons array *must* be empty
('' or nil), so to add buttons without text, pass ' ' string (one space
char). It is not necessary to provide image indexes for all
buttons (it is sufficient to assign index for first button only).
But in place, correspondent to separator button (defined by string '-'),
any integer must be passed to assign follow image indexes correctly.
See example.
|*Toolbar adding buttons sample.
Code below shows how to call TBAddButtons method to add two buttons with
a separator between these buttons. idxNew and idxOld are integer
expressions assigning image indexes to buttons 'New' and 'Old'. This
indexes are zero-based and refer to bitmap images, added earlier (either
in creating toolbar by call of NewToolbar or later in call of TBAddBitmap).
!
! TBAddButtons( [ '&New', '-', '&Old', '' ], [ idxNew, 0, idxOld ] );
!
|*
To add check buttons, use prefix '+' or '-' in button definition
string. If next character is '!', such buttons are grouped to a
radio-group. Also, it is possible to use '^' prefix (must be first) to
define button with small drop-down section (use also OnTBDropDown event
to respond to clicking drop down section of such buttons).
|<br>
This function returns command id for first added button (other
id's can be calculated incrementing the result by one for each
button, except separators, which have no command id).
|<br>
Note: for static toolbar (single in application and created
once) ids are started from value 100. }
function TBInsertButtons( BeforeIdx: Integer; Buttons: array of PKOLChar;
BtnImgIdxArray: array of Integer ): Integer;
{* |<#toolbar>

command identifier for first button inserted (other can be calculated
incrementing returned value needed times. See also TBAddButtons. }
procedure TBDeleteButton( BtnID: Integer );

procedure TBClear;
{* |<#toolbar>
Deletes all buttons. Dufa }
procedure TBAssignEvents( BtnID: Integer; Events: array of TOnToolbarButtonClick );
{* |<#toolbar>
Allows to assign separate OnClick events for every toolbar button.
BtnID should be toolbar button ID or index of the first button to
assign event. If it is an ID, events are assigned to buttons in
creation order. Otherwise, events are assigned in placement order.
Anyway, separator buttons are not skipped, so pass at least nil for such
button as an event.
|<br>
Please note, that though not all buttons should exist before
assigning events to it, therefore at least the first button
(specified by BtnID) must be already added before calling TBAssignEvents. }
procedure TBResetImgIdx( BtnID, BtnCount: Integer );
{* |<#toolbar>
Resets image index for BtnCount buttons starting from BtnID. }
property CurItem: Integer read fCurItem;
{* |<#toolbar>
For toolbar, in OnClick event this property can be used to determine
which button was clicked (100-based button id in toolbar). It is also
possible to use CurIndex property (zero-based) for this purpose as
well, but do not assume, that CurItem always equal to CurIndex+100.
At least, it is possible to call TBItem2Index function to convert
button ID to its index in toolbar.
}
property TBButtonCount: Integer read GetItemsCount; //TBGetButtonCount;
{* |<#toolbar>
Returns count of buttons on toolbar. The same as Count. }

of indexes (each item in the array passed is a pointer to
Integer, containing button index when the procedure is callled,
then all these indexes are relaced with a correspondent button ID).}

"Transparent" method (returns @Self as a result), which (when called)
provides "standard" keyboard interface for formatting Rich text (just
call this method, for example:
! RichEd1 := NewRichEdit( Panel1, [ ] ).SetAlign( caClient ).RE_FmtStandard;
Following keys will be maintained additionally:
|<pre>
CTRL+I - switch "Italic",
CTRL+B - switch "Bold",
CTRL+U - switch "Underline",
CTRL+SHIFT+U - swith underline type
and turn underline on (note, that some of underline styles
can not be shown properly in RichEdit v2.0 and lower,
though RichEdit2.0 stores data successfully).
CTRL+O - switch "StrikeOut",
CTRL+'gray+' - increase font size,
CTRL+'gray-' - decrease font size,
CTRL+SHIFT+'gray+' - superscript,
CTRL+SHIFT+'gray-' - subscript.
CTRL+SHIFT+Z - ReDo
|</pre>
And, though following standard formatting keys are provided by RichEdit
control itself in Windows2000, some of these are not functioning
automatically in earlier Windows versions, even for RichEdit2.0. So,
functionality of some of these (marked with (*) ) are added here too:
|<pre>
CTRL+L - align paragraph left, (*)
CTRL+R - align paragraph right, (*)
CTRL+E - align paragraph center, (*)
CTRL+A - select all, (*)
double-click on word - select word,
CTRL+Right - to next word,
CTRL+Left - to previous word,
CTRL+Home - to the beginning of text,
CTRL+End - to the end of text.
CTRL+Z - UnDo
|</pre>
If You originally assign some (plain) text to Text property, switching "underline"
can also change other font attributes, e.g., "bold" - if fsBold style is
in default Font. To prevent such behavior, select entire text first (see
SelectAll) and make assignment to RE_Font property, e.g.:
! RichEd1.SelectAll;
! RichEd1.RE_Font := RichEd1.RE_Font;
! RichEd1.SelLength := 0;
|<br>
And, some other notices about formatting. Please remember, that only True
Type fonts can be succefully scaled and transformed to get desired effects
(e.g., bold). By default, RichEdit uses System font face name, which can
even have problems with fsBold style. Please remember also, that assigning
RE_Font to RE_Font just initializying formatting attributes, making all
those valid in entire text, but does not change font attributes. To use
True Type font, directly assign face name You wish, e.g.:
! RichEd1.SelectAll;
! RichEd1.RE_Font := RichEd1.RE_Font;
! RichEd1.RE_Font.FontName := 'Arial';
! RichEd1.SelLength := 0;

This property allows to control insert/overwrite mode. First, to examine, if
insert or overwrite mode is current (but it is necessary either to
access this property, at least once, immediately after creating RichEdit
control, or to assign event OnRE_InsOvrMode_Change to your handler).
Second, to set desired mode programmatically - by assigning value to
this property (You also have to initialize monitoring procedure by either
reading RE_OverwriteMode property or assigning handler to event
OnRE_InsOvrMode_Change immediately following RichEdit control creation). }
property OnRE_InsOvrMode_Change: TOnEvent read fOnREInsModeChg write fOnREInsModeChg;

Options: TBitBtnOptions; Layout: TGlyphLayout; GlyphBitmap: HBitmap; GlyphCount: Integer ): PControl;
{* |<#control>
Creates image button (actually implemented as owner-drawn). In Options,
it is possible to determine, whether bitmap or image list used to contain
one or more (up to 5) images, correspondent to certain BitBtn state.
|<br>&nbsp;&nbsp;&nbsp;
For case of imagelist (option bboImageList), it is possible to use a
number of glyphs from the image list, starting from image index given
by GlyphCount parameter. Number of used glyphs is passed in that case
in high word of GlyphCount parameter (if 0, one image is used therefore).
For bboImageList, BitBtn can be Transparent (and in that case bboNoBorder
style can be useful to draw custom buttons of non-rectangular shape).
|<br>&nbsp;&nbsp;&nbsp;
For case of bitmap BitBtn, image is stretched down (if too big), but can
not be transparent. It is not necessary for bitmap BitBtn to pass correct
GlyphCount - it is calculated on base of bitmap size, if 0 is passed.
|<br>&nbsp;&nbsp;&nbsp;
And, certainly, BitBtn can be without glyph image (text only). For that
case, it is therefore is more flexible and power than usual Button (but
requires more code). E.g., BitBtn can change its <D Font>, <D Color>,
and to be totally <D Transparent>.
Moreover, BitBtn can be <D Flat>, bboFixed, <D SpeedButton> and
have property <D RepeatInterval>.
|<br>&nbsp;&nbsp;&nbsp;
Note: if You use bboFixed Style, use OnChange event instead of OnClick,
because <D Checked> state is changed immediately however OnClick occure
only when mouse or space key released (and can be not called at all if
mouse button is released out of BitBtn bounds). Also, bboFixed defines
only which glyph to show (the border if it is not turned off behaves as
usual for a button, i.e. it becomes lowered and then raised again at any click).

applicable to BitBtn:

designed for such purpose). }
//[NewMDIxxx DECLARATIONS]
function NewMDIClient( AParent: PControl; WindowMenu: THandle ): PControl;
{* |<#control>
Creates MDI client window, which is a special type of child window,
containing all MDI child windows, created calling NewMDIChild function.
On a form, MDI client behaves like a panel, so it can be placed and sized
(or aligned) like any other controls. To minimize flick during resizing
main form having another aligned controls, place MDI client window on
a panel and align it caClient in the panel.
|<br>Note:
MDI client must be a single on the form. }
function NewMDIChild( AParent: PControl; const ACaption: KOLString ): PControl;
{* |<#control>
Creates MDI client window. AParent should be a MDI client window,
created with NewMDIClient function. }
//[NewSplitter DECLARATIONS]
function NewSplitter( AParent: PControl; MinSizePrev, MinSizeNext: Integer ): PControl;
{* |<#control>
Creates splitter control, which will separate previous one (i.e. last
created one before splitter on the same parent) from created
next, allowing to user to adjust size of separated controls by dragging
the splitter in desired direction. Created splitter becomes vertical
or horizontal depending on Align style of previous control on the same
parent (if caLeft/caRight then vertical, if caTop/caBottom then horizontal).
|<br>&nbsp;&nbsp;&nbsp;
Please note, what if previous control has no Align equal to caLeft/caRight
or caTop/caBottom, splitter will not be able to function normally. If
previous control does not exist, it is yet possible to use splitter as
a resizeable panel (but set its initial Align value first - otherwise it
is not set by default. Also, change Cursor property as You wish in that
case, since it is not set too in case, when previous control does not
exist).
|<br>&nbsp;&nbsp;&nbsp;
Additional parameters determine, which minimal size (width or height -
correspondently to split direction) is allowed for left (top) control
and to rest of client area of parent, correspondently. (It is possible
later to set second control for checking its size with MinSizeNext
value - using TControl.SecondControl property). If -1 passed,
correspondent control size is not checked during dragging of splitter.
Usually 0 is more suitable value (with this value, it is garantee, that
splitter will be always available even if mouse was released far from the
edge of form).
|<br>&nbsp;&nbsp;&nbsp;
It is possible for user to press Escape any time while dragging splitter
to abort all adjustments made starting from left mouse button push and
begin of drag the splitter. But remember please, that such event is
controlled using timer, and therefore correspondent keyboard events
are received by currently focused control. Be sure, that pressing Escape
will not affect to any control on form, which could be focused, otherwise
filter keyboard messages (by yourself) to prevent undesired handling of
Escape key by certain controls while splitting. (Use Dragging property
to check if splitter is dragging by user with mouse).

|<br> to feedback to switch between tabs assign your handler to OnSelChange
event;
|<br>Note, that by default, tab control is created with a border lowered to
tab control's parent. To remove it, you can apply WS_EX_TRANSPARENT extended
style (see TControl.ExStyle property), but painting of some child controls
can be strange a bit in this case (no border drawing for edit controls was

//[NewToolbar DECLARATION]
function NewToolbar( AParent: PControl; Align: TControlAlign; Options: TToolbarOptions;
Bitmap: HBitmap; const Buttons: array of PKOLChar;
const BtnImgIdxArray: array of Integer ) : PControl;
{* |<#control>
Creates toolbar control. Bitmap (if present) must contain images for all buttons
excluding separators (defined by string '-' in Buttons array) and system images,
otherwise last buttons will no have images at all. Image width for every button
is assumed to be equal to Bitmap height (if last of "squares" has
insufficient width, it will not be used). To define fixed buttons, use
characters '+' or '-' as a prefix for button string (even empty). To
create groups of (radio-)buttons, use also '!' follow '+' or '-'. (These rules
are similar used in menu creation). To define drop down button, use (as
first) prefix '^'. (Do not forget to set <D OnTBDropDown> event for this
case). If You want to assign images to buttons not in the same order
how these are placed in Bitmap (or You use system bitmap), define for every
button (in BtnImgIdxArray array) indexes for every button (excluding
separator buttons). Otherwise, it is possible to define index only for first
button (e.g., [0]). It is also possible to change TBImages[ ] property
for such purpose, or do the same in method TBSetBtnImgIdx).
|<br>
Following properties, methods and event are specially designed to work with
toolbar control:
|#toolbar
|<br>&nbsp;&nbsp;&nbsp;
If your project uses Align property to align controls, this can conflict with
toolbar native aligning. To solve such problem, place toolbar to parent panel,
which has its own Align property assigned to desired value.
|<br>
To create toolbar with buttons, drawn from top to bottom, instead from left
to right, combine caLeft / caRight in Align parameter and style tboWrapable
when create toolbar. To adjust width of vertically aligned toolbar, it is
possible to call ResizeParentLeft for it. E.g.:
! P0 := NewPanel( W, esRaised ) .SetSize( 30, 0 ) .SetAlign( caLeft );
! // ^^^^^^^^^^^^^^^^^ //////
!TB := NewToolbar( P0, caLeft, [ tboNoDivider, tboWrapable ], DWORD(-1),
! // ////// ///////////
! [ ' ', ' ', ' ', '-', ' ', ' ' ],
! [ STD_FILEOPEN ] ).ResizeParentRight;
!//Note, that caLeft is *must*, and tboWrapable style too. SetSize for
!//parent panel is not necessary, but only if ResizeParentRight is called
!//than for Toolbar.
|<br><br>
One more note: if You create toolbar without text labels (passing ' ' for
each button You add), include also option tboTextRight to fix incorrect
sizing of buttons under Windows9x.
|<br>
And, certainly, if you use image lists rather then bitmap, all written
above about Bitmap become absolutely incorrect.

There is a known bug exist with similar invisible tray-iconized applications.
When a menu is activated in response to tray mouse event, if there was
not active window, belonging to the application, the menu is not disappeared
when mouse is clicked anywhere else. This bug is occure in Windows9x/ME.
To avoid it, activate first your form window. This last window shoud have
status visible (but, certainly, there are no needs to place it on visible
part of screen - change its position, so it will not be visible for user,
if You wish).
<br>
Also, to make your application "invisible" but until special event is occure,
use Applet separate from the main form, and make for both Visible := False.
This allows for You to make your form visible any time You wish, and without
making application button visible if You do not wish.

<R Data sorting (quicksort implementation)>
This part contains implementation of 'quick sort' algorithm,
based on following code:
|<pre>
| TQSort by Mike Junkin 10/19/95.
| DoQSort routine adapted from Peter Szymiczek's QSort procedure which
| was presented in issue#8 of The Unofficial Delphi Newsletter.
| TQSort changed by Vladimir Kladov (Mr.Bonanzas) to allow 32-bit
| sorting (of big arrays with more than 64K elements).
|</pre>
Finally, this sort procedure is adapted to XCL (and then to KOL)
requirements (no references to SysUtils, Classes etc. TQSort object
is transferred to a single procedure call and DoQSort method is
renamed to SortData - which is a regular procedure now). }

and e2>e2). Items are enumerated from 0 to uNElem. }
TSwapEvent = procedure (const Data : Pointer; const e1,e2 : Dword);
{* Event type to define swap procedure which is swapping two elements of an

Following formatting characters can be used in menu template strings:
|&L=<br><b>%1</b>
<L &amp; (in identifier)> - to underline next character and use it as a shortcut character

<L + (in front of identifier)> - to make item checked. If also

{* Set of utility methods to work with files
and reqistry.
When programming KOL, which is Windows API-oriented, You should
avoid alien (for Windows) embedded Pascal files handling, and
use API-calls which implemented very well. This set of functions
is intended to make this easier.
Also TDirList object implementation present here and some registry
access functions, which allow to make code more elegant.
