public virtual signal bool state_set (bool state)
The state_set signal on GtkSwitch is emitted to change the underlying state.
It is emitted when the user changes the switch position. The default handler keeps the state in sync with the active property.
To implement delayed state change, applications can connect to this signal, initiate the change of the underlying state, and call set_state when the underlying state change is complete. The signal handler should return true to prevent the default handler from running.
Visually, the underlying state is represented by the trough color of the switch, while the active property is represented by the position of the switch.
