Hey thanks, John,
   I did what you said yesterday, and got what I wanted with
gtk_window_set_transient_for(). But I don't know what
gtk_window_set_type_hint() is for. I checked the gtk reference manual
and it didn't say what the "hint", which is one of the parameters I
need to pass, was. Do you mind telling me how to use this function?

Thank you, that's exactly what I needed! I then made a window just like
that, but there's a new problem. I set the initial floating window's
position with gtk_window_move(), and set it to be unresizable. And when
I dragged the left edge to expand it the "whole window" moved to the
right, and when it moved to the right its left edge wasn't even under
my mouse. Is it a bug in gtk?

Also I've noticed that just like with Gimp, whenever I drag a child
window across its parent the parent never updates itself, unless I let
go the left button of my mouse, but that way it looks pretty ugly
because I can erase my whole parent window by dragging the child window
around. Do you know the solution for this? I tried to add an idle
function to make the parent update itself constantly, but it's no use.

Also, do you know a way to create a window that has a border, and a
title bar with no icon and no max/min/close buttons, and it's actually
draggable by using its title bar? That is what I want to create for my
application.

Thank you. I will do as you suggested. Once I get my internet
connection back at home I'll download Gimp's source. Thanks a lot! I
really appreciate your help.

Best wishes,

Jack
