register_window

Description:

[ Version ( since = "3.8" ) ]
public void register_window (Window window)

Registers a Window with the widget and sets it up so that the widget receives events for it.

Call unregister_window when destroying the window.

Before 3.8 you needed to call set_user_data directly to set this up. This is now deprecated and you should use register_window instead. Old code will keep working as is, although some new features like transparency might not work perfectly.

Parameters:

this	a Widget
window	a Window
