xfwm per window decoration (ssh -X)

Neckara · 2017-04-02 21:09:21

Hi,

Currently I try to have a system similar to Qubes-OS (which is based on xfce) on a Debian Jessie with xfce 4.10 based on VirtualBox VMs :
I start a detached VM (Debian with xfce) and lauch applications on this VM from the host with "ssh -X" (VirtualBox seamless mode is not perfect). It seems that the theme used for the new window is the host's theme.

Now, I would like to differentiate host's windows from guest's windows (launched with "ssh -X" from the host). The guest's window's title ends with "(on guest hostname)".

Thus I seek to have different window decoration / theme for the two types of windows (host and guest). However, I have no idea how to do that and I am not sure that xfwm allows per windows themes.

Do you have some idea ?

Thanks in advance.

That's the way it's supposed to work. The local window manager will manage all of the windows.

Unfortunately, I don't think this is possible.

But is there some kind of tricks such as launching a Window "in another window", or get a kind of "window handle" from the window title, then modify the Window decoration from the window handle ?

Qubes seems to succeed to do that with xfce, but I am kind of lost in their sources.

EDIT : I can get information and window ID with :

xwininfo -root -tree

It looks like they patched the xfwm4 source to provide access to that atom.

I really begin to dislike Qubes, they use existing work but does not seem to care to pull request their changes.

I am not really familiar with Xfwm's sources, and not confident enough to build it from sources. Maybe I will try to open an issue and see.
