[Java-gnome-developer] Re: Use of destroy()

[Laurent M. <la...@ao...>]

It does not crash the JVM in that case (out of luck), but produces a
critical GTK error message:

(java-gnome:1903): Gtk-CRITICAL **: file gtkcontainer.c: line 1285 (gtk_container_foreach): assertion `GTK_IS_CONTAINER (container)' failed

Remove the destroy() and all is fine. 

I must admit it is probably not very smart to destroy the source of an
event when handling the event, but didn't know how to destroy the gtk
object in an other manner. And it was not clear to me that gtk would
do that itself.
