Hi, this is my first message to glade-devel.
I wrote the attached simple (and is somewhat a quick and dirty hack)
to implement a preview feature in glade-3. The patch is against the
svn revision 1693.
It is still not ready for inclusion, but I would like to hear feedback
from developers and users about how to do it right.
There are currently some issues:
* The currently seen project is saved in /tmp/temp.glade
* The project must have a toplevel widget called window1
*...
Feedback would be welcome, thanks.
