Thanks Paul, I've got set_rules_hint (true) but I do not know about the "style engine" or how to control it. The methods I'm looking @ in the Gtk::TreeView are: void Gtk::TreeView::set_grid_lines(TreeViewGridLines g_lines) Glib::PropertyProxy<bool> Gtk::TreeView::property_enable_grid_lines() and neither one work - not in the gtkmm dll. I've looking on line, too, and have not found code examples to do this. If set_rules_hint(true) actually enables the grid lines, then how does the style engine override this? Thanks Paul.

The documentation states 2 methods to do so but neither are actually w/in the the gtkmm library. Would someone mind telling me how to turn on the gridlines in a TreeView?its a style option, not really property of the TreeView. TreeView::set_rules_hint (true) will tell the style engine that you'd like the grid lines, but the style engine may override that. --p -- Sincerely, Allen Gene Allen Saucier, Jr Senior Software Engineer CAS, Inc 100 Quality Circle Huntsville, AL 35806 or PO Box 11190 Huntsville, AL 35814 (256) 922-6453 (w) "As for I and my house, we shall follow the Lord" Joshua 25:14 |
