Hi!

Is there any easy way to scroll GtkTreeView to make selected row visible? GtkTreeView is on GtkScrolledWindow.

I tried that, but gtk_tree_view_scroll_to_cell(buffer, &iter, NULL, FALSE, FALSE) doesn't take effect!

From the documentation:

Quote:
If column is NULL, then no horizontal scrolling occurs. Likewise, if path is NULL no vertical scrolling occurs. At a minimum,

void show_selected_row (GtkWidget *tree_view)
{
    GtkTreeModel *model;
    GtkTreeSelection *sel;
    GtkTreePath *path;
   
    model = gtk_tree_view_get_model (GTK_TREE_VIEW (tree_view));
    sel = gtk_tree_view_get_selection (GTK_TREE_VIEW (tree_view));
    gtk_tree_selection_get_selected (sel, *model, &iter);
    path = gtk_tree_model_get_path (model, &iter);
    gtk_tree_view_scroll_to_cell (GTK_TREE_VIEW (tree_view),
                                  path, NULL, FALSE, 0, 0);
}
