How do I keep a window on top of the desktop? manage minimization and maximization of windows?
[…] “Staying on top” depends on the window manager in a way largely out of Perl/Tk’s control. Until we make the time to write up a more complete explanation, see the Tcl-ers’ Wiki for hints as to what’s involved. Most of this general theory is irrelevant. What people generally want is for dialog boxes to stay high when wm->transient is set, and this is reasonably reliable.
