// =========
// Since CEF 102 the Linux demos with the GlobalCEFApp.MultiThreadedMessageLoop
// property set to FALSE and using GTK2 require a custom build of CEF binaries
// with use_gtk=false set via GN_DEFINES.
// This is a demo with the simplest web browser you can build using CEF4Delphi and
// it doesn't show any sign of progress like other web browsers do.
// Remember that it may take a few seconds to load if Windows update, your antivirus or
// any other windows service is using your hard drive.
// Depending on your internet connection it may take longer than expected.
// Please check that your firewall or antivirus are not blocking this application
// or the domain "google.com". If you don't live in the US, you'll be redirected to
// another domain which will take a little time too.
// This demo uses a TChromium and a TCEFLinkedWindowParent
// We need to use TCEFLinkedWindowParent in Linux to update the browser
// visibility and size automatically.
// Destruction steps
// =================
// 1. FormCloseQuery sets CanClose to FALSE calls TChromium.CloseBrowser which triggers the TChromium.OnClose event.
// 2. TChromium.OnClose sets aAction to cbaClose to destroy the browser, which triggers the TChromium.OnBeforeClose event.
// 3. TChromium.OnBeforeClose sets FCanClose := True and sends CEF_BEFORECLOSE to close the form.

// ATTENTION
// =========
// Since CEF 102 the Linux demos with the GlobalCEFApp.MultiThreadedMessageLoop
// property set to FALSE and using GTK2 require a custom build of CEF binaries
// with use_gtk=false set via GN_DEFINES.
// This is a simple CEF browser in "off-screen rendering" mode (a.k.a OSR mode)
// with a different executable for the Chromium subprocesses and an external
// message pump
// Chromium needs the key press data available in the GDK signals
// "key-press-event" and "key-release-event" but Lazarus doesn't expose that
// information so we have to call g_signal_connect to receive that information
// in the GTKKeyPress function.
// Chromium renders the web contents asynchronously. It uses multiple processes
// and threads which makes it complicated to keep the correct browser size.
// In one hand you have the main application thread where the form is resized by
// the user. On the other hand, Chromium renders the contents asynchronously
// with the last browser size available, which may have changed by the time
// Chromium renders the page.
// For this reason we need to keep checking the real size and call
// TChromium.WasResized when we detect that Chromium has an incorrect size.
// TChromium.WasResized triggers the TChromium.OnGetViewRect event to let CEF
// read the current browser size and then it triggers TChromium.OnPaint when the
// contents are finally rendered.
// TChromium.WasResized --> (time passes) --> TChromium.OnGetViewRect --> (time passes) --> TChromium.OnPaint
// You have to assume that the real browser size can change between those calls
// and events.
// This demo uses a couple of fields called "FResizing" and "FPendingResize" to
// reduce the number of TChromium.WasResized calls.
// FResizing is set to True before the TChromium.WasResized call and it's set to
// False at the end of the TChromium.OnPaint event.
// FPendingResize is set to True when the browser changed its size while
// FResizing was True. The FPendingResize value is checked at the end of
// TChromium.OnPaint to check the browser size again because it changed while
// Chromium was rendering the page.
// The TChromium.OnPaint event in the demo also calls
// TBufferPanel.UpdateBufferDimensions and TBufferPanel.BufferIsResized to check
// the width and height of the buffer parameter, and the internal buffer size in
// the TBufferPanel component.
// Lazarus usually initializes the GTK WidgetSet in the initialization section
// of the "Interfaces" unit which is included in the LPR file. This causes
// initialization problems in CEF and we need to call "CreateWidgetset" after
// the GlobalCEFApp.StartMainProcess call.
// Lazarus shows a warning if we remove the "Interfaces" unit from the LPR file
// so we created a custom unit with the same name that includes two procedures
// to initialize and finalize the WidgetSet at the right time.
// This is the destruction sequence in OSR mode :
// 1- FormCloseQuery sets CanClose to the initial FCanClose value (False) and
// calls Chromium1.CloseBrowser(True) which will destroy the internal browser
// immediately.
// 2- Chromium1.OnBeforeClose is triggered because the internal browser was
// destroyed. FCanClose is set to True and we can close the form safely.

// ATTENTION
// =========
// Since CEF 102 the Linux demos with the GlobalCEFApp.MultiThreadedMessageLoop
// property set to FALSE and using GTK2 require a custom build of CEF binaries
// with use_gtk=false set via GN_DEFINES.
// This demo uses a CEF browser in "off-screen rendering" mode (a.k.a OSR mode)
// but instead of copying the raw bitmap information it uses an OpenGL texture
// to accelerate drawing the contents.
// It's recommemded to avoid using OpenGL in multiple threads so this demo uses
// a external message pump to execute all CEF events in the main appliction
// thread.
// This demo uses a TOpenGLControl control from the "LazOpenGLContext" package.
//
// Before you install the LazOpenGLContext package you need to install the
// libgl1-mesa-dev package in Linux.
// If you use Ubuntu you would have to open a Terminal and execute the following
// commands :
// sudo apt-get update -y
// sudo apt-get install -y libgl1-mesa-dev
//
// Follow these steps to install the LazOpenGLContext package in Lazarus:
// 1.- Click on the "Package" option of the main Lazarus menu.
// 2.- Select the "Install/Uninstall packages" option.
// 3.- Choose "LazOpenGLContext" on the right side panel.
// 4.- Click on the "Install selection" button.
// 5.- Click on the "Save and rebuild IDE" button.
// 6.- Click on the "Continue" button.
// 7.- Wait a moment until Lazarus restarts.
// The code in this demo is a translation of the official CEF sample application
// called "cefsimple" and it also copies a few code fragments from the OSRDemo
// in the fpCEF3 project.
// In case you run this demo inside a virtual machine or using an unsupported
// graphics card you may get a white screen and/or OpenGL errors.
// Lazarus usually initializes the GTK WidgetSet in the initialization section
// of the "Interfaces" unit which is included in the LPR file. This causes
// initialization problems in CEF and we need to call "CreateWidgetset" after
// the GlobalCEFApp.StartMainProcess call.
// Lazarus shows a warning if we remove the "Interfaces" unit from the LPR file
// so we created a custom unit with the same name that includes two procedures
// to initialize and finalize the WidgetSet at the right time.
// This is the destruction sequence in OSR mode :
// 1- FormCloseQuery sets CanClose to the initial FCanClose value (False) and
// calls Chromium1.CloseBrowser(True) which will destroy the internal browser
// immediately.
// 2- Chromium1.OnBeforeClose is triggered because the internal browser was
// destroyed. FCanClose is set to True and we can close the form safely.

// When TChromium needs to show a new popup window it executes TChromium.OnBeforePopup.
// LCL components *MUST* be created and destroyed in the main thread but CEF executes the
// TChromium.OnBeforePopup in a different thread.
// For this reason this demo creates a hidden popup form (TChildForm) in case CEF needs to show a popup window.
// TChromium.OnBeforePopup calls TChildForm.CreateClientHandler to initialize some parameters and create the new ICefClient.
// After that, it sends a CEF_CREATENEXTCHILD message to show the popup form and create a new one.
// All the child forms must be correctly destroyed before closing the main form. Read the code comments in uChildForm.pas
// to know how the popup windows are destroyed.

// 4. TChromium.OnBeforeClose sets FCanClose := True and sends a CEF_BEFORECLOSE message to close the form in the main thread.

// This is a demo with the simplest web browser you can build using CEF4Delphi and
// it doesn't show any sign of progress like other web browsers do.
// Remember that it may take a few seconds to load if Windows update, your antivirus or
// any other windows service is using your hard drive.
// Depending on your internet connection it may take longer than expected.
// Please check that your firewall or antivirus are not blocking this application
// or the domain "google.com". If you don't live in the US, you'll be redirected to
// another domain which will take a little time too.
// This demo uses a TChromium and a TCEFLinkedWindowParent
// We need to use TCEFLinkedWindowParent in Linux to update the browser
// visibility and size automatically.
// Most of the TChromium events are executed in a CEF thread and this causes
// issues with most GTK API functions. If you need to update the GUI, store the
// TChromium event parameters and use SendCompMessage (Application.QueueAsyncCall)
// to do it in the main application thread.
// Destruction steps
// =================
// 1. FormCloseQuery sets CanClose to FALSE calls TChromium.CloseBrowser which triggers the TChromium.OnClose event.
// 2. TChromium.OnClose sets aAction to cbaClose to destroy the browser, which triggers the TChromium.OnBeforeClose event.
// 3. TChromium.OnBeforeClose sets FCanClose := True and sends CEF_BEFORECLOSE to close the form.

// This is a simple CEF browser in "off-screen rendering" mode (a.k.a OSR mode)
// It uses the default CEF configuration with a multithreaded message loop and
// that means that the TChromium events are executed in a CEF thread.
// GTK is not thread safe so we have to save all the information given in the
// TChromium events and use it later in the main application thread. We use
// critical sections to protect all that information.
// For example, the browser updates the mouse cursor in the
// TChromium.OnCursorChange event so we have to save the cursor in FPanelCursor
// and use Application.QueueAsyncCall to update the Panel1.Cursor value in the
// main application thread.
// The raw bitmap information given in the TChromium.OnPaint event also needs to
// be stored in a TCEFBitmapBitBuffer class instead of a simple TBitmap to avoid
// issues with GTK.
// Chromium needs the key press data available in the GDK signals
// "key-press-event" and "key-release-event" but Lazarus doesn't expose that
// information so we have to call g_signal_connect to receive that information
// in the GTKKeyPress function.
// Chromium renders the web contents asynchronously. It uses multiple processes
// and threads which makes it complicated to keep the correct browser size.
// In one hand you have the main application thread where the form is resized by
// the user. On the other hand, Chromium renders the contents asynchronously
// with the last browser size available, which may have changed by the time
// Chromium renders the page.
// For this reason we need to keep checking the real size and call
// TChromium.WasResized when we detect that Chromium has an incorrect size.
// TChromium.WasResized triggers the TChromium.OnGetViewRect event to let CEF
// read the current browser size and then it triggers TChromium.OnPaint when the
// contents are finally rendered.
// TChromium.WasResized --> (time passes) --> TChromium.OnGetViewRect --> (time passes) --> TChromium.OnPaint
// You have to assume that the real browser size can change between those calls
// and events.
// This demo uses a couple of fields called "FResizing" and "FPendingResize" to
// reduce the number of TChromium.WasResized calls.
// FResizing is set to True before the TChromium.WasResized call and it's set to
// False at the end of the TChromium.OnPaint event.
// FPendingResize is set to True when the browser changed its size while
// FResizing was True. The FPendingResize value is checked at the end of
// TChromium.OnPaint to check the browser size again because it changed while
// Chromium was rendering the page.
// The TChromium.OnPaint event in the demo also calls
// TBufferPanel.UpdateBufferDimensions and TBufferPanel.BufferIsResized to check
// the width and height of the buffer parameter, and the internal buffer size in
// the TBufferPanel component.
// Lazarus usually initializes the GTK WidgetSet in the initialization section
// of the "Interfaces" unit which is included in the LPR file. This causes
// initialization problems in CEF and we need to call "CreateWidgetset" after
// the GlobalCEFApp.StartMainProcess call.
// Lazarus shows a warning if we remove the "Interfaces" unit from the LPR file
// so we created a custom unit with the same name that includes two procedures
// to initialize and finalize the WidgetSet at the right time.
// This is the destruction sequence in OSR mode :
// 1- FormCloseQuery sets CanClose to the initial FCanClose value (False) and
// calls Chromium1.CloseBrowser(True) which will destroy the internal browser
// immediately.
// 2- Chromium1.OnBeforeClose is triggered because the internal browser was
// destroyed. FCanClose is set to True and calls
// SendCompMessage(CEF_BEFORECLOSE) to close the form asynchronously.
