Re: Gtk execution question

[lorenzo zampese electrolux it]

My idea was the same, but I supposed there was a different way as in
Tcl/Tk scripting language (tk_wait) :)

Ok. Thank you

How about putting that "gtk_widget_show(window);" into your callback?

Also, I assume you're calling into gtk_main() even though you didn't
show it.  You never really want to "stop" GTK execution, since it
has to be running in gtk_main() (or a custom loop) even for your
dialog to work.
