Sorry, I did post a small example that demonstrates the unusual (buggy?) behavior in a follow-up post. The more I dug into it, the weirder it became, and the more convinced I am that it's a bug in Gtk. Or at least, a bug in the HPUX implementation of it. I'm waiting about a week to see if I hear back from anyone on the list that they can reproduce the problem in their environment.
In the example code, it came down to adding a gtk_widget_set_size_request. If that line is in the code, then when you gtk_dialog_run, it immediately re-executes the change-value signal callback. Comment it out, recompile, and it works as you'd expect. I continued to play with it a bit. I can make other calls besides gtk_widget_set_size_request that will also make change-value reentrant, but I couldn't see any clear pattern. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
