[arch-general] wmctrl fishy top left corner offset

[Ralf Mardorf]

Hi,

does anybody know, what makes the x/y coordinates of a window drift,
when setting them by the wmctrl -e option? The offset differs for other
Linux users. Instead of figuring out by trial and error what values are
needed to correct the offset, it would be nice to calculate the needed
values.

Regards,
Ralf

If I substract ...

  
[rocketmouse at archlinux ~]$ cat ~/.rocketmouse/win75/config
X_FIX=4
Y_FIX=50

[rocketmouse at archlinux ~]$ cat /usr/local/bin/win75
#!/bin/bash
eval $(xdotool getwindowgeometry --shell $(xdotool getactivewindow))
X_FIX=$(grep X_FIX ~/.rocketmouse/win75/config | cut -d"=" -f2)
Y_FIX=$(grep Y_FIX ~/.rocketmouse/win75/config | cut -d"=" -f2)
((XX=X-X_FIX))
((YY=Y-Y_FIX))
WIDTH=$(calc "int($WIDTH*0.75)")
case $1 in
  "") HEIGHT=$(calc "int($HEIGHT*0.75)");;
esac
echo "x:$X-$X_FIX=$XX/y:$Y-$Y_FIX=$YY"
wmctrl -i -r $WINDOW -b remove,maximized_vert,maximized_horz
wmctrl -i -r $WINDOW -e "0,$XX,$YY,$WIDTH,$HEIGHT"
eval $(xdotool getwindowgeometry --shell $(xdotool getactivewindow))
echo "x:$X-$X_FIX=$XX/y:$Y-$Y_FIX=$YY"
exit


... it's fixed.
