Signal

GtkSwitch::state-set

since: 3.14

Declaration 

gboolean
state_set (
  GtkSwitch* self,
  gboolean state,
  gpointer user_data
)

Description [src]

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 GtkSwitch:active property.

To implement delayed state change, applications can connect to this signal, initiate the change of the underlying state, and call 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 GtkSwitch:active property is represented by the position of the switch.

Default handler:

The default handler is called after the handlers added via g_signal_connect().

Available since: 3.14

Parameters

state

Type: gboolean

The new state of the switch.

Return value

Type: gboolean

TRUE to stop the signal emission.
