GTK program with no window & how to lose mouse cursor

[Tom Knowles <tom peters co uk>]

Havoc, (I think this got lost when I originally sent it)
Thanks for the reply relating to items below on running on GTK/touchscreen
A couple of questions if I may...

I tried the programs with no window, as recommended, and this seems more the 
ticket for my purpose. However, I don't seem to be able to get to flat X from 
the gui login, the latter sort of necessary for pure touch operation and, I 
think, the only way into pucker LTSP operation, my next step.  Any 
suggestions?
Also, re pixmap/mask to lose the mouse cursor, where/how do I do this?
Many thanks
Tom
