I don't know how it is with Qt, but the response from the GTK developers
these days is typically "stop doing whatever you did which required you
to solve problem XYZ".

Where "whatever you did" can be reparenting a window onto another
window, moving a window to an absolute coordinate on-screen, warping the
mouse pointer, dynamically updating the menu bar, or closing a display
connection, all of which are today discouraged by the GTK developers.
