gdk-window-raise (window)

window -- a gdk-window object

Raises the window to the top of the z-order (stacking order), so that other windows with the same parent window appear below the window. This is true whether or not the windows are visible.

If window is a toplevel, the window manager may choose to deny the request to move the window in the z-order, the function gdk-window-raise only requests the restack, does not guarantee it.
