[Glade-users] [gtkbuilder+glade3.4]The Child-window can not creat again

[Tristan Van Berkom]

How did you end up using a GtkCList in GtkBuilder format ?

was it converted from an old libglade format Glade file ?
did you get the appropriate error/warning dialog when trying
to save the GtkCList in GtkBuilder format from Glade ?

GtkCList is deprecated and unsupported, for list views you are
expected to use treeviews etc.

Cheers,
       -Tristan
