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. This function does nothing. Use the gtk:window-resize function and compute the geometry yourself.
