Hi! > I need to retrieve the button number in a "clicked" event > handler for a treeview column, but I don't know how to > read it from the event data (is there any?). Can someone help? If I understand correctly, you want to catch clicks on the treeview and then analyse whick mouse button was used? If so, then: 1) Connect "button-press-event" to the TreeView 2) In the connected callback check if event->type == GDK_BUTTON_PRESS; then event->button holds the button number (e.g. 1, 2 or 3). There is a nice example in GtkTreeView Tutorial: http://scentric.net/tutorial/sec-sel-click-menus.html Best wishes, Andrej _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
