Programmatically setting _NET_WM_STATE values

I also would like to know the answer of this question.

I have the same problem with _NET_WM_STATE property values. Even the mentioned "_NET_WM_STATE_SKIP_TASKBAR" works, but after minimizing, it disappears from the properties and the window get back to the taskbar.

Is it a feature or bug?

Re: Programmatically setting _NET_WM_STATE values

Split from https://forum.xfce.org/viewtopic.php?id=3749 - that was a really old thread. Continuing here.

Have you tried either wmctrl or devilspie? See: https://forum.xfce.org/viewtopic.php?id=6755

Re: Programmatically setting _NET_WM_STATE values

Generally, I am trying to use these windows properties in my own programs, calling XChangeProperty function. The use of xprop utility is only as a diagnosing and testing, after I noticed that _NET_WM_STATE property can't be set in usual way.

The code is in assembly language, but is pretty straightforward and probably is OK. At least setting other than _NET_WM_STATE properties goes normally. So, I concluded that the _NET_WM_STATE property is also written properly, but shortly after that some other program overwrites its value. The best overwriter candidate (IMHO) is the window manager of XFCE.

I am not very sure how other WM behaves and can't test it just now.

Re: Programmatically setting _NET_WM_STATE values

In case you don't get anymore replies here, you might consider posting to the xfce4-dev mailing list or possibly creating a "[Question]" bug report on the bug tracker. The xfwm4 developer seems more active there than on these forums.
