Description pulp 2005-04-21 21:04:53 UTC 
it would be nice if the main window of OO have the "_NET_WM_PID" property set.
with this property it would be possible to identive the main window more easily
(for third party programs which add a system tray or whatever)

sorry if this is already set in the 2.x version (was not able to test it with
the newest version)

code example for linux(unix):

Atom net_wm_pid=XInternAtom(display, "_NET_WM_PID", False);
int pid=getpid();

XChangeProperty (GDK_DISPLAY(), main_window,
      net_wm_pid, XA_CARDINAL, 32, PropModeReplace,
      (guchar *)&pid, 1);

ps: the wm_class strings could be changed to something usefull too ;)

"soffice" for example

confirmed; but identifying the main window would be a side effect at best.

PID is used by window managers in conjunction with the _NET_WM_PING protocol;
some window managers decide that an application that does not respond fast
enough should be killed. Which is a really crap idea, but window managers are
all about preventing applications from doing their job.

the gtk plugin supports this by virtue of using gtk; the generic plugin (and
derivatives like kde and kde4) now supports this, too.

fixed in CWS vcl110
