All methods of this class are static. Many of the Windows-only functions here are utilized in the PyWin32 example.

  • OnSize (Win)
  • OnEraseBackground (Win)
  • SetTitle (Win)
  • SetIcon (Win)
  • GetParentHandle

  • gtk_plug_new (Linux)
  • gtk_widget_show (Linux)
  • InstallX11ErrorHandlers (Linux)

Windows-only. This method processes WM_SETFOCUS message which is sent to a window after it has gained the keyboard focus.

Windows-only. This method should be called during WM_SIZE message which is sent to a window after its size has changed. Most examples should call the Browser.SetBounds method during size events. The pywin32.py example is an exception and it needs to use the WindowUtils.OnSize method.

Windows-only. This method processes WM_ERASEBKGND message which is sent when the window background must be erased (for example, when a window is resized).

Windows-only. Set the title for the main window or popup window. The default implementation of DisplayHandler.OnTitleChange() calls this method to set the title for a window.

Windows-only. Set the icon for the popup window. The default implementation of DisplayHandler.OnTitleChange() calls this method to set the icon for a window that wasn't created explicitily (for example a popup window), the icon is inherited from the parent window. Icon parameter accepts only "inherit", you cannot pass here a path to an icon (currently not implemented).

Get a parent handle.

On Linux and Mac this method always returns 0. @TODO.

Check whether this is a valid window handle.

On Linux and Mac this method always returns True. @TODO.

Linux-only.

Linux-only.

Linux-only. Install xlib error handlers so that the application won't be terminated on non-fatal errors. Must be done after initializing GTK.

CEF Python calls this function automatically during a call to Initialize, so there is no more need to call it manually in most cases.
