Protected procedure doCreateCustomView; override;

ICefViewDelegateEvents

Public procedure CreateTopLevelWindow;

Create a new Window.

Public procedure Show;

Show the Window.

Public procedure ShowAsBrowserModalDialog(const browser_view: ICefBrowserView);

Show the Window as a browser modal dialog relative to |browser_view|. A parent Window must be returned via ICefWindowDelegate.OnGetParentWindow and |browser_view| must belong to that parent Window. While this Window is visible, |browser_view| will be disabled while other controls in the parent Window remain enabled. Navigating or destroying the |browser_view| will close this Window automatically. Alternately, use show() and return true (1) from ICefWindowDelegate.OnIsWindowModalDialog for a window modal dialog where all controls in the parent Window are disabled.

Public procedure Hide;

Hide the Window.

Public procedure CenterWindow(const size_: TCefSize);

Sizes the Window to |size| and centers it in the current display.

Public procedure Close;

Close the Window.

Public procedure Activate;

Activate the Window, assuming it already exists and is visible.

Public procedure Deactivate;

Deactivate the Window, making the next Window in the Z order the active Window.

Public procedure BringToTop;

Bring this Window to the top of other Windows in the Windowing system.

Public procedure Maximize;

Maximize the Window.

Public procedure Minimize;

Minimize the Window.

Public procedure Restore;

Restore the Window.

Public function AddOverlayView(const view: ICefView; docking_mode: TCefDockingMode; can_activate: boolean): ICefOverlayController;

Add a View that will be overlayed on the Window contents with absolute positioning and high z-order. Positioning is controlled by |docking_mode| as described below. Setting |can_activate| to true (1) will allow the overlay view to receive input focus. The returned cef_overlay_controller_t object is used to control the overlay. Overlays are hidden by default.

With CEF_DOCKING_MODE_CUSTOM: 

1. The overlay is initially hidden, sized to |view|'s preferred size,
   and positioned in the top-left corner.
2. Optionally change the overlay position and/or size by calling
   CefOverlayController methods.
3. Call CefOverlayController::SetVisible(true) to show the overlay.
4. The overlay will be automatically re-sized if |view|'s layout
   changes. Optionally change the overlay position and/or size when
   OnLayoutChanged is called on the Window's delegate to indicate a
   change in Window bounds.

With other docking modes: 

1. The overlay is initially hidden, sized to |view|'s preferred size,
   and positioned based on |docking_mode|.
2. Call CefOverlayController::SetVisible(true) to show the overlay.
3. The overlay will be automatically re-sized if |view|'s layout changes
   and re-positioned as appropriate when the Window resizes.

Overlays created by this function will receive a higher z-order then any child Views added previously. It is therefore recommended to call this function last after all other child Views have been added so that the overlay displays as the top-most child of the Window.

Public procedure ShowMenu(const menu_model: ICefMenuModel; const screen_point: TCefPoint; anchor_position : TCefMenuAnchorPosition);

Show a menu with contents |menu_model|. |screen_point| specifies the menu position in screen coordinates. |anchor_position| specifies how the menu will be anchored relative to |screen_point|.

Public procedure CancelMenu;

Cancel the menu that is currently showing, if any.

Public procedure SetDraggableRegions(regionsCount: NativeUInt; const regions: PCefDraggableRegionArray);

Set the regions where mouse events will be intercepted by this Window to support drag operations. Call this function with an NULL vector to clear the draggable regions. The draggable region bounds should be in window coordinates.

Public procedure SendKeyPress(key_code: Integer; event_flags: cardinal);

Simulate a key press. |key_code| is the VKEY_* value from Chromium's ui/events/keycodes/keyboard_codes.h header (VK_* values on Windows). |event_flags| is some combination of EVENTFLAG_SHIFT_DOWN, EVENTFLAG_CONTROL_DOWN and/or EVENTFLAG_ALT_DOWN. This function is exposed primarily for testing purposes.

Public procedure SendMouseMove(screen_x, screen_y: Integer);

Simulate a mouse move. The mouse cursor will be moved to the specified (screen_x, screen_y) position. This function is exposed primarily for testing purposes.

Public procedure SendMouseEvents(button: TCefMouseButtonType; mouse_down, mouse_up: boolean);

Simulate mouse down and/or mouse up events. |button| is the mouse button type. If |mouse_down| is true (1) a mouse down event will be sent. If |mouse_up| is true (1) a mouse up event will be sent. If both are true (1) a mouse down event will be sent followed by a mouse up event (equivalent to clicking the mouse button). The events will be sent using the current cursor position so make sure to call send_mouse_move() first to position the mouse. This function is exposed primarily for testing purposes.

Public procedure SetAccelerator(command_id, key_code : Integer; shift_pressed, ctrl_pressed, alt_pressed, high_priority: boolean);

Set the keyboard accelerator for the specified |command_id|. |key_code| can be any virtual key or character value. Required modifier keys are specified by |shift_pressed|, |ctrl_pressed| and/or |alt_pressed|. ICefWindowDelegate.OnAccelerator will be called if the keyboard combination is triggered while this window has focus.

The |high_priority| value will be considered if a child ICefBrowserView has focus when the keyboard combination is triggered. If |high_priority| is true (1) then the key event will not be forwarded to the web content (`keydown` event handler) or ICefKeyboardHandler first. If |high_priority| is false (0) then the behavior will depend on the ICefBrowserView.SetPreferAccelerators configuration.

Public procedure RemoveAccelerator(command_id: Integer);

Remove the keyboard accelerator for the specified |command_id|.

Public procedure RemoveAllAccelerators;

Remove all keyboard accelerators.

Properties

Public property Title : ustring read GetTitle write SetTitle;

Get the Window title.

Public property WindowIcon : ICefImage read GetWindowIcon write SetWindowIcon;

Get the Window icon.

Public property WindowAppIcon : ICefImage read GetWindowAppIcon write SetWindowAppIcon;

Get or set the Window App icon. This should be a larger icon for use in the host environment app switching UI. On Windows, this is the ICON_BIG used in Alt-Tab list and Windows taskbar. The Window icon will be used by default if no Window App icon is specified.

Public property Display : ICefDisplay read GetDisplay;

Returns the Display that most closely intersects the bounds of this Window. May return NULL if this Window is not currently displayed.

Public property ClientAreaBoundsInScreen : TCefRect read GetClientAreaBoundsInScreen;

Returns the bounds (size and position) of this Window's client area. Position is in screen coordinates.

Public property WindowHandle : TCefWindowHandle read GetWindowHandle;

Retrieve the platform window handle for this Window.

Public property IsClosed : boolean read GetIsClosed;

Returns true (1) if the Window has been closed.

Public property IsActive : boolean read GetIsActive;

Returns whether the Window is the currently active Window.

Public property IsAlwaysOnTop : boolean read GetIsAlwaysOnTop write SetAlwaysOnTop;

Returns whether the Window has been set to be on top of other Windows in the Windowing system.

Public property IsFullscreen : boolean read GetIsFullscreen write SetFullscreen;

Returns true (1) if the Window is fullscreen.

Public property IsMaximized : boolean read GetIsMaximized;

Returns true (1) if the Window is maximized.

Public property IsMinimized : boolean read GetIsMinimized;

Returns true (1) if the Window is minimized.

Published property OnWindowCreated : TOnWindowCreatedEvent read FOnWindowCreated write FOnWindowCreated;

Called when |window| is created.

Published property OnWindowClosing : TOnWindowClosingEvent read FOnWindowClosing write FOnWindowClosing;

Called when |window| is closing.

Published property OnWindowDestroyed : TOnWindowDestroyedEvent read FOnWindowDestroyed write FOnWindowDestroyed;

Called when |window| is destroyed. Release all references to |window| and do not attempt to execute any functions on |window| after this callback returns.

Published property OnWindowActivationChanged : TOnWindowActivationChangedEvent read FOnWindowActivationChanged write FOnWindowActivationChanged;

Called when |window| is activated or deactivated.

Published property OnWindowBoundsChanged : TOnWindowBoundsChangedEvent read FOnWindowBoundsChanged write FOnWindowBoundsChanged;

Called when |window| bounds have changed. |new_bounds| will be in DIP screen coordinates.

Published property OnGetParentWindow : TOnGetParentWindowEvent read FOnGetParentWindow write FOnGetParentWindow;

Return the parent for |window| or NULL if the |window| does not have a parent. Windows with parents will not get a taskbar button. Set |is_menu| to true (1) if |window| will be displayed as a menu, in which case it will not be clipped to the parent window bounds. Set |can_activate_menu| to false (0) if |is_menu| is true (1) and |window| should not be activated (given keyboard focus) when displayed.

Published property OnIsWindowModalDialog : TOnIsWindowModalDialogEvent read FOnIsWindowModalDialog write FOnIsWindowModalDialog;

Return true (1) if |window| should be created as a window modal dialog. Only called when a Window is returned via get_parent_window() with |is_menu| set to false (0). All controls in the parent Window will be disabled while |window| is visible. This functionality is not supported by all Linux window managers. Alternately, use ICefWindow.ShowAsBrowserModalDialog() for a browser modal dialog that works on all platforms.

Published property OnGetInitialBounds : TOnGetInitialBoundsEvent read FOnGetInitialBounds write FOnGetInitialBounds;

Return the initial bounds for |window| in density independent pixel (DIP) coordinates. If this function returns an NULL CefRect then GetPreferredSize() will be called to retrieve the size, and the window will be placed on the screen with origin (0,0). This function can be used in combination with ICefView.GetBoundsInScreen() to restore the previous window bounds.

Published property OnGetInitialShowState : TOnGetInitialShowStateEvent read FOnGetInitialShowState write FOnGetInitialShowState;

Return the initial show state for |window|.

Published property OnIsFrameless : TOnIsFramelessEvent read FOnIsFrameless write FOnIsFrameless;

Published property OnWithStandardWindowButtons : TOnWithStandardWindowButtonsEvent read FOnWithStandardWindowButtons write FOnWithStandardWindowButtons;

Return true (1) if |window| should be created with standard window buttons like close, minimize and zoom. This function is only supported on macOS.

Published property OnGetTitlebarHeight : TOnGetTitlebarHeightEvent read FOnGetTitlebarHeight write FOnGetTitlebarHeight;

Return whether the titlebar height should be overridden, and sets the height of the titlebar in |titlebar_height|. On macOS, it can also be used to adjust the vertical position of the traffic light buttons in frameless windows. The buttons will be positioned halfway down the titlebar at a height of |titlebar_height| / 2.

Published property OnCanResize : TOnCanResizeEvent read FOnCanResize write FOnCanResize;

Return true (1) if |window| can be resized.

Published property OnCanMaximize : TOnCanMaximizeEvent read FOnCanMaximize write FOnCanMaximize;

Return true (1) if |window| can be maximized.

Published property OnCanMinimize : TOnCanMinimizeEvent read FOnCanMinimize write FOnCanMinimize;

Return true (1) if |window| can be minimized.

Published property OnCanClose : TOnCanCloseEvent read FOnCanClose write FOnCanClose;

Return true (1) if |window| can be closed. This will be called for user- initiated window close actions and when ICefWindow.close() is called.

Published property OnAccelerator : TOnAcceleratorEvent read FOnAccelerator write FOnAccelerator;

Called when a keyboard accelerator registered with ICefWindow.SetAccelerator is triggered. Return true (1) if the accelerator was handled or false (0) otherwise.

Published property OnKeyEvent : TOnWindowKeyEventEvent read FOnKeyEvent write FOnKeyEvent;

Called after all other controls in the window have had a chance to handle the event. |event| contains information about the keyboard event. Return true (1) if the keyboard event was handled or false (0) otherwise.

Published property OnWindowFullscreenTransition : TOnWindowFullscreenTransitionEvent read FOnWindowFullscreenTransition write FOnWindowFullscreenTransition;

Called when |window| is transitioning to or from fullscreen mode. On MacOS the transition occurs asynchronously with |is_competed| set to false (0) when the transition starts and true (1) after the transition completes. On other platforms the transition occurs synchronously with |is_completed| set to true (1) after the transition completes. With the Alloy runtime you must also implement ICefDisplayHandler.OnFullscreenModeChange to handle fullscreen transitions initiated by browser content.
