Unfortunately you'll have to walk the "stoney" road then, using
XSetWMHints and set window_group of the XWMHints struct.

To do so, you'd first get it on all relevant windows:

XWMHints *hints = XGetWMHints ( QX11Info::display(),
this->QWidget::winId() );

then change it:
hints->window_group = common_value;

then set it:
XSetWMHints( QX11Info::display(),
this->QWidget::winId(), hints );

This is of course not portable at all.

"common_value" should be some global hook, preferably the ID of a
persistant window of your group on which presence you can rely (from
some application core?)
Do NOT(!) abuse the root window for this.

The winId doesn't have to be real (for this specific occasion) but that
might very well lead to trouble elsewhere (or cause random clashes if
the winId actually exists)

To align it among your nodes, you could either use dbus or store a
custom property on the root window (yes, that's ok this time ;-)

Cheers,
Thomas
