gtk:toggle-tool-button-active (object)

object -- a gtk:toggle-tool-button widget
setting -- a boolean whether the toggle tool button should be active

Accessor of the active slot of the gtk:toggle-tool-button class. The gtk:toggle-tool-button-active function queries a toggle tool button and returns its current state. The (setf gtk:toggle-tool-button-active) function sets the status.

Set to true if you want the toggle tool button to be 'pressed in', and false to raise it. This action causes the "toggled" signal to be emitted.
