ToggleButtons are like normal Buttons, but when clicked they remain activated, or pressed, until clicked again.
|
To retrieve the state of the ToggelButton, you can use the
get_active() method. This returns true if the button
is "down". You can also set the toggle button's state, with set_active(). Note that, if you do this, and the state actually changes, it causes the
"clicked" signal to be emitted. This is usually what you want.
You can use the toggled() method to toggle the button, rather than forcing it to be up or down: This switches the button's state, and causes the toggled signal to be emitted. Gtk::ToggleButton is most useful as a base class for the Gtk::CheckButton and Gtk::RadioButton classes. |
