I want to send a keystroke to a GLUT program on X11, but I can't find there's an X11 client attached to the GLUT program.
I do this, using the most excellent demo program for the chipmunk 2d physics package:
xlsclients -a|sort >aa
chipmunk_demos (in another window)
xlsclients -a|sort >bb
diff aa bb
and there's no difference.
My eventual hope is that I can control the GLUT program by sending key events with the equivalent of:
xdotool key --window 0x4000002 a
So my questions:
- how can I remote control a GLUT program running on linux/X11?
- Is there a way to get an X11 window id for a GLUT program?
Install xtrace, then:
In Terminal 1:
xtrace -d :0 -D :8 | grep CreateWindow
In Terminal 2:
You should get a line with:
... CreateWindow depth=0x18 window=0x04a00002 ...
xdotool actually contains powerful search functionality, which recent versions make even easier to use. It doesn't make sense to use
xtrace like this, just use
xdotool search instead
