Buttons

Gtk::Button. Standard buttons, usually marked with a label or picture. Pushing one triggers an action. See the Button section.

Gtk::ToggleButton. Unlike a normal Button, which springs back up, a ToggleButton stays down until you press it again. It might be useful as an on/off switch. See the ToggleButton section.

Gtk::CheckButton. These act like ToggleButtons, but show their state in small squares, with their label at the side. They should be used in most situations which require an on/off setting. See the CheckButton section.

Named after the station selectors on old car radios, these buttons are used in groups for options which are mutually exclusive. Pressing one causes all the others in its group to turn off. They are similar to ToggleButtons or CheckButtons (a small widget with a label at the side), but usually look different. There is no separate radio button class. Check buttons and toggle buttons can act as radio buttons. See the Radio Button section.
