Window.beginResizeDragForDevice

void beginResizeDragForDevice(gdk.types.WindowEdge edge,  gdk.device.Device device,  int  button,  int  rootX,  int  rootY,  uint  timestamp)

Begins a window resize operation (for a toplevel window). You might use this function to implement a “window resize grip,” for example; in fact #GtkStatusbar uses it. The function works best with window managers that support the

Extended Window Manager Hints

but has a fallback implementation for other window managers.

Parameters

`edge`	the edge or corner from which the drag is started
`device`	the device used for the operation
`button`	the button being used to drag, or 0 for a keyboard-initiated drag
`rootX`	root window X coordinate of mouse click that began the drag
`rootY`	root window Y coordinate of mouse click that began the drag
`timestamp`	timestamp of mouse click that began the drag (use [gdk.event.Event.getTime])
