// Instead of a regular TTabSheet we use a custom TBrowserTab class that
|

// inherits from TTabSheet and instead of a regular TFrame we use a custom
|
||||
// TBrowserFrame class that inherits from TFrame.
|
||||
|
||||
// To create a new tab you need to call TBrowserTab.CreateBrowser in the last
|
||||
// step to create all the browser components and initialize the browser.
|
||||
|
||||
// To close a tab you have to call TBrowserTab.CloseBrowser and wait for a
|
||||
// CEF_DESTROYTAB message that includes TBrowserTab.TabID in TMessage.wParam.
|
||||
// Then you find the tab with that unique TabID and free it.
|
||||
|
||||
// TBrowserFrame has all the usual code to close CEF4Delphi browsers following
|
||||
// a similar destruction sequence than the OSRExternalBrowserPump demo :
|
||||
//
|
||||
// This is the destruction sequence in OSR mode :
|
||||
// 1- FormCloseQuery sets CanClose to the initial FCanClose value (False) and calls chrmosr.CloseBrowser(True).
|
||||
// 2- chrmosr.CloseBrowser(True) will trigger chrmosr.OnClose and the internal
|
||||
// browser will be destroyed immediately.
|
||||
// 3- chrmosr.OnBeforeClose is triggered because the internal browser was destroyed.
|
||||
// FCanClose is set to True and sends WM_CLOSE to the form.
|
||||
|
||||
// This demo also uses custom forms to open popup browsers in the same way as
|
||||
// the PopupBrowser2 demo. Please, read the code comments in that demo for all
|
||||
// details about handling the custom child forms.
|
||||
|
||||
// Additionally, this demo also creates new tabs when a browser triggers the
|
||||
// TChromium.OnBeforePopup event.
|
||||
|
||||
// To close safely this demo you must close all the browser tabs first following
|
||||
// this steps :
|
||||
//
|
||||
// 1. FormCloseQuery sets CanClose to FALSE and calls CloseAllBrowsers and FClosing
|
||||
// is set to TRUE.
|
||||
// 2. Each tab will send a CEF_DESTROYTAB message to the main form to free that tab.
|
||||
// 3. Each child form will send a CEF_CHILDDESTROYED message to the main form.
|
||||
// 3. When TPageControl has no tabs and all the child forms are also closed then we
|
||||
// can set FCanClose to TRUE and send a WM_CLOSE message to the main form to
|
||||
// close the application.
