Detailed Description
Implement this interface to handle window events.
The methods of this class will be called on the browser process UI thread unless otherwise indicated.
Member Function Documentation
◆ CanClose()
Return true if |window| can be closed.
This will be called for user- initiated window close actions and when CefWindow::Close() is called.
◆ CanMaximize()
Return true if |window| can be maximized.
◆ CanMinimize()
Return true if |window| can be minimized.
◆ CanResize()
Return true if |window| can be resized.
◆ GetInitialBounds()
Return the initial bounds for |window| in density independent pixel (DIP) coordinates.
If this method returns an empty CefRect then GetPreferredSize() will be called to retrieve the size, and the window will be placed on the screen with origin (0,0). This method can be used in combination with CefView::GetBoundsInScreen() to restore the previous window bounds.
◆ GetInitialShowState()
|
inlinevirtual |
Return the initial show state for |window|.
◆ GetParentWindow()
|
inlinevirtual |
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 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 if |is_menu| is true and |window| should not be activated (given keyboard focus) when displayed.
◆ IsFrameless()
Return true if |window| should be created without a frame or title bar.
The window will be resizable if CanResize() returns true. Use CefWindow::SetDraggableRegions() to specify draggable regions.
◆ OnAccelerator()
|
inlinevirtual |
Called when a keyboard accelerator registered with CefWindow::SetAccelerator is triggered.
Return true if the accelerator was handled or false otherwise.
◆ OnKeyEvent()
|
inlinevirtual |
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 if the keyboard event was handled or false otherwise.
◆ OnWindowActivationChanged()
|
inlinevirtual |
Called when |window| is activated or deactivated.
◆ OnWindowCreated()
Called when |window| is created.
◆ OnWindowDestroyed()
Called when |window| is destroyed.
Release all references to |window| and do not attempt to execute any methods on |window| after this callback returns.
