gtk-window-resize-to-geometry (window width height)

window -- a gtk-window widget
width -- an integer with the width in resize increments to resize the window to
height -- an integer with the height in resize increments to resize the window to

Like the gtk-window-resize function, but width and height are interpreted in terms of the base size and increment set with the gtk-window-set-geometry-hints function. The gtk-window-resize-to-geometry function has been deprecated since version 3.20 and should not be used in newly written code. This function does nothing. Use the gtk-window-resize function and compute the geometry yourself.
