, I have tried clicking on a GtkTreeView
and placing it down. A popup window shows up asking me to
enter a GtkTreeView TreeView Model. I create a new object
called liststore1. I then right click the Tree View and select
Edit and get the following errors which crash glade altogether
(I see no way on the Edit toolbar to assign datatypes). How
should I proceed???

(glade:9725): Gtk-CRITICAL **: gtk_cell_view_set_displayed_row: assertion
`GTK_IS_TREE_MODEL (cell_view->priv->model)' failed

(glade:9725): Gtk-WARNING **:
/build/buildd/gtk+3.0-3.2.0/./gtk/gtktreeview.c:1944: invalid property id
14 for "ubuntu-almost-fixed-height-mode" of type `GParamBoolean' in
`GtkTreeView'

(glade:9725): Gtk-WARNING **: GtkContainerClass::add not implemented for
`GtkTreeView'

Gtk-ERROR **: GtkBox child GladeEditorTable minimum height: -4 < 0
Trace/breakpoint trap

Thanks,

Saku
