Needed: Simple X app to bring itself (i.e., xterm) for foreground
Kenny McCormack
I.e., I would like to be able to run something from a shell running in
an xterm that would bring the xterm to the foreground. Obviously, it
would be best if there was an existing app for this (maybe a feature of
some otherwise unrelated package). Otherwise, I'd appreciate tips on
how to write it in C. I have written (small) X apps before.
Or, maybe it can be in done in TCL/TK. I have some experience there as
well.

Oops - problem.
It looks good, but it seems to only work with genuine xterms. I use
rxvt and it doesn't work there.
So, anyone want to give me a C or TCL/TK solution?

Sorry for the long post, but you asked for it. :-) At
least it's not a binary.
Here's a program that raises a window based on the window's
title. You could change the string comparison against MAIN
to test for whether the window in question is the one you
want to raise. I'll lease the coding of that as an exercise
for the reader. :-)

Thanks much. Works fine. Here's my slightly edited version:
