Hi Eddie, For your above tristate button, this should be achievable without adding anything to GTK+. What you want I think is three GtkRadioButtons, and you want them to be 'linked' together with the CSS - I think this is already the default appearance when placing 3 radio buttons together in a GtkButtonBox. I don't think however that a Joystick gizmo widget qualifies as general purpose enough to be included in GTK+, this kind of thing should certainly be application specific, or, shared in some other library with similar widgets (dials ? for apps like q-base and sound mixers ?)
