Description [src]

The ::device-changed signal is emitted whenever a device has changed in the hierarchy, either slave devices being disconnected from their master device or connected to another one, or master devices being added or removed a slave device.

If a slave device is detached from all master devices (gdk_device_get_associated_device() returns NULL), its GdkDeviceType will change to GDK_DEVICE_TYPE_FLOATING, if it’s attached, it will change to GDK_DEVICE_TYPE_SLAVE.

Default handler:

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


device GdkDevice

The GdkDevice that changed.

 The data is owned by the caller of the function.
