struct Gtk::Switch::StateSetSignal

Overview

Emitted to change the underlying state.

The ::state-set signal is emitted when the user changes the switch position. The default handler calls Gtk::Switch#state= with the value of state.

To implement delayed state change, applications can connect to this signal, initiate the change of the underlying state, and call Gtk::Switch#state= when the underlying state change is complete. The signal handler should return true to prevent the default handler from running.
