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
