Description Colin Keenan 2014-09-26 03:32:32 UTC
xwininfo -id $(xdotool getactivewindow)

should give a lot of information about the active window, including the relative number of pixels between the X window and the out edge of a decoration. It works fine in Xfce under Arch Linux, but people using my scripts have complained that it doesn't work under Ubuntu 14.04 Unity, and just reports:

Relative upper-left X:  0  
Relative upper-left Y:  0

For any window even though they do have a 28 pixel title bar and 1 px borders on sides and bottom. I got that information from https://wiki.ubuntu.com/Unity/Theming, which probably also has enough information for whoever works on this to get xwininfo properly determine the Relative upper-left X and Y numbers. They will almost always be 28 and 1, but could have been changed by following the instructions on that link.
Comment 1 Colin Keenan 2014-09-26 14:37:50 UTC
The information I needed from xwininfo Relative information is available from:

xprop _NET_FRAME_EXTENTS --xid=$(xdotool getactivewindow)

So, however that is working, seems like it should work the same in xwininfo.
