tree scroll

[Eric Pastoor <epastoor vt edu>]

I am trying to force a scroll to a row in a tree. I have a tree with  
about 20 items in of which only about 10 are visible. Scrolling with  
the mouse on the tree works fine.  After a user presses a button, I  
am trying to scroll to the newest row added to the tree(which is not  
usually the last row).  I would like to select the row and then  
scroll to it so that it is visble. I am trying to use the  
gtk_tree_view_scroll_to_cell function but nothing happens when I use  
it. Here is a code snippet of what I am doing.  Is there something  
you need to call after you call the scroll_to_cell to repaint or  
revalidate the tree?

Note: iter was set to the newly added row. Selecting the row works  
fine here. It's just not viewable without scrolling.


                        GtkTreePath* iterPath =
                                gtk_tree_model_get_path(treeModel, &iter);
                        gtk_tree_view_expand_to_path(treeView, iterPath);

                        GtkTreeSelection* select = gtk_tree_view_get_selection (treeView);
                        gtk_tree_selection_select_path(select, iterPath);

                        GtkTreeViewColumn* column = gtk_tree_view_get_column(treeView, 0);
                        gtk_tree_view_set_cursor(treeView, iterPath, column, 0);

                        gtk_tree_view_scroll_to_cell(treeView,
                                                     iterPath,
                                                     NULL,
                                                     false, // do not use align
                                                     0, // row align is ignored
                                                     0); // col align is ignored
                        gtk_tree_path_free(iterPath);


If anyone has any suggestions or sees something I am doing wrong, I'd  
greatly appreciate it.

Thanks!
Eric
