I'm reading your posts in the gtk-devel, and you should not expect too
much help there.

I recommend you to try the gtk-app-devel list, where - for sure - you'll
find more help.

>From your posts I understand your problem is with the handling of the
currently selected cell in the drop down. It seems you want the
currently selected item to be visible on the drop down list.

If I'm right, I'm sure you will find those functions useful.

GtkTreeSelection* 
gtk_tree_view_get_selection (GtkTreeView *tree_view);

gboolean    
gtk_tree_selection_get_selected (GtkTreeSelection *selection,
                                 GtkTreeModel **model,
                                 GtkTreeIter *iter);

GtkTreePath*
gtk_tree_model_get_path        (GtkTreeModel *tree_model,
                                GtkTreeIter *iter);
void       
gtk_tree_view_scroll_to_cell    (GtkTreeView *tree_view,
                                 GtkTreePath *path,
                                 // column can be NULL
                                 GtkTreeViewColumn *column, 
				 // if FALSE alignment is not used
                                 gboolean use_align,
				 // 0.0 left/top, 1.0 right/bottom, 0.5 center.
                                 gfloat row_align, 
                                 gfloat col_align);


The rationale can be: pick the current selection - an iter and model, both are return values on gtk_tree_selection_get_selected() -  take the path with gtk_tree_model_get_path() and scroll to the cell that path.

I hope I had undestood your problem.

Again, I recommend you to ask for help in the gtk-app-devel list. The gtk-devel is quite technical and about gtk internals. They don't use to help when asking about how gtk works.


Best Regards.
