This is happening because the column that you have created has a single activatable cell renderer. The column is then seen as a single activatable entity. (It is more clearly seen in keyboard navigation, when this column gets focus it will draw the focus indicator around all cell renderers instead of around a single cell renderer, again because there is only a single cell renderer that can be activated). Often this is the behavior you want, for example when you pack a text renderer next to the toggle renderer. It will act the same as a regular toggle button which also allows clicking on the text. > GtkCellRendererToggle. This is no good in this particular case. Is Why exactly is it no good in this case?

Thanks in advance for any ideas. The only way I can think of so quickly to work around this is probably to subclass GtkCellRendererToggle and override the activate method to check the event coordinates that are provided with the cell_area or background_area coordinates. (GtkCellRendererToggle itself does not do this and immediately emits the toggled signal). regards, -kris. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
