setting X11 window title/class/resource

[Drew Hess <drew hess gmail com>]

Hi,

There's a really neat utility called evrouter
(http://www.bedroomlan.org/~alexios/coding_evrouter.html) that allows
you to map /dev/input/event* device events to X11 keys or button
presses.

I'd like to use evrouter to enable a shuttle/jog controller in my
gtkmm app.  However, evrouter relies on standard X11 window title,
class and/or resource names to identify the window in which an input
event takes place.  It appears that Window::set_title() doesn't set
any of these, nor does set_wmclass().

It looks like this is true of all gtk(mm) apps; is that right?  What's
the most straightfoward way to get enough X11 context from a gtkmm
Window to set its X11 window title?

thanks
