[Gtk-sharp-list] glade autoconnect strangeness

[Peter Williams]

Hi,

This is the expected behavior if you look at the code: gtk-
sharp/glade/XML.custom. Basically, when you call Autoconnect(), it
iterates through all fields with the [Widget] attribute and sets them
with a GetWidget() call. So any [Widget] attribute that doesn't
correspond to a defined widget in the current XML file will be nulled
out.

You could argue whether this is desirable behavior or not (it would be
easy to not clear the field if it's already non-null). But it's not hard
to work around. Usually people just have a one-to-one mapping between
XML files and classes. It shouldn't be hard to define an inner class
that takes care of your dialog box.
