 |
|
Ok, this one is pretty trivial, but it's worth asking.
I use perlpanel, and I start several terms in my .xinitrc/.xsession file. quite often, the terms will be drawn to the screen before perlpanel is drawn, and thusly get placed behind my panel. Is there a way to make my .xsession waitt until perlpanel is drawn fully, before I create my terms?
I can imagine the syntax looking something like this:
| Code: | perlpanel & panelid=$!
wait $panelid
aterm &
aterm &
... |
but clearly, that would fail, as my .xsession script would wait until perlpanel is completely finished (aka, killed) before I create my aterms. Is there any sort of signaling, or sig_status_request one can throw at normal X programs?

This might work:
| Code: |
perlpanel &
t=1
while [ $t != 0 ]
do
xwininfo -name "perlpanel" &>/dev/null # xwininfo can also give you the right name
t=$?
done
aterm &
aterm &
|
No guarantees here... That could easily loop forever (though seems to work for me) |

ooooh, I like that. I can even grep out the correct settings, and just make my aterms pop up in the right spot.
Thanks a ton. That's fantastic.

Here's what I decided to go with, hopefully that will eliminate any possibility of an endless loop.
| Code: | perlpanel 2> /dev/null & PANELID=$!
# Do other things that need to be done here to minimize potential waiting time.
while [ ! -z "`/usr/bin/env ps -p $PANELID -o comm=`" ] ; do
until [ ! -z "`xwininfo -name "perlpanel" 2> /dev/null`" ] ; do
sleep .1
done
break;
done
for a in `seq 1 6` ; do
aterm &
done

Thank you again for the xwininfo tip. I have been looking for that for a LONG time.
I started out stripping the geometry out of the xwininfo result, but it was just too cumbersome to actually apply that to information to multiple aterms. Since each Aterm doesn't necessarily in sequence, I'd have to grab the xwininfo from the last window to appear, who's name has changed because of my .bashrc ... it was more of a headache than was needed, especailly since openbox does a perfectly find job of putting windows where they need to go.
