  • Method Details

    • onStateSet

      boolean onStateSet(boolean state)
      Emitted to change the underlying state.

      The ::state-set signal is emitted when the user changes the switch
      position. The default handler keeps the state in sync with the
      [property@Gtk.Switch:active] property.

      To implement delayed state change, applications can connect to this
      signal, initiate the change of the underlying state, and call
      [method@Gtk.Switch.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 [property@Gtk.Switch:active] property is
      represented by the position of the switch.
      Parameters:
      state - the new state of the switch
      Returns:
      %TRUE to stop the signal emission
