Well, maybe I missed the point. If you map an existing window (such as 
MCS plug-ins windows for example), then GTK doesn't update the user_time 
as there was no real user activity on the widnow since the last unmap. 
As a result, the window will unlikely be focused.

To avoid that, prior to show the window, you should reset the user_time 
to GTK_CURRENT_TIME (actually 0) on the corresponding GdkWindow so that 
the windows gets focused.

Now, I'm not sure what you mean by xfdesktop window as the vroot window 
is unlikely to be mapped/unmapped.

Cheers,
Olivier.
