Thanks So, I should be able to just - handle the GtkCellRenderer::editing-started signal and store the GtkCellEditable* that it gives me. - call gtk_cell_editable_start_editing(celleditable, 0) from my GtkCellRendererText::edited signal handler, to restart editing. ? That's not working for me so far, but I haven't tried it in a simple test case. -- Murray Cumming murrayc@xxxxxxxxxxx www.murrayc.com www.openismus.com _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
