Re: Is it possible having different GtkAdjustment values in GtkTreeView

["Tadej Borovšak" <tadeboro gmail com>]

I forgot to explain why G_TYPE_OBJECT does not work in this situation.
The GtkTreeModel is just an interface for GtkList/TreeStore objects
and is not derived from GObject but from GInterface. So it is
perfectly legal to use G_TYPE_INTERFACE instead GTK_TYPE_TREE_MODEL in
my code.

Another key function call to getting GtkCellRendererCombo working is
g_object_set, which sets "editable" property to TRUE, so you can edit
your renderer.
