Returns: Boolean	Gdk.Display

Flushes any requests queued for the windowing system and waits until all requests have been handled. This is often used for making sure that the display is synchronized with the current state of the program. Calling gdk_display_sync() before gdk_error_trap_pop() makes sure that any errors generated from earlier requests are handled before the error trap is removed. This is most useful for X11. On windowing systems where requests are handled synchronously, this function will do nothing. Returns: none	Gdk.Display

Warps the pointer of display to the point x,y on the screen screen, unless the pointer is confined to a window by a grab, in which case it will be moved as far as allowed by the grab. Warping the pointer creates events as if the user had moved the mouse instantaneously to the destination. Note that the pointer should normally be under the control of the user. This function was added to cover some rare use cases like keyboard navigation support for the color picker in the GtkColorSelectionDialog. Parameters: Gdk.Screen screen Required (not null) Number x Required (not null) Number y Required (not null) Returns: none	Gdk.Display
