Functions
Description
ClutterDeviceManager is a singleton object, owned by Clutter, which maintains the list of ClutterInputDevices.
Depending on the backend used by Clutter it is possible to use the “device-added” and “device-removed” to monitor addition and removal of devices.
ClutterDeviceManager is available since Clutter 1.2
Functions
clutter_device_manager_get_default ()
ClutterDeviceManager *
clutter_device_manager_get_default (void);
Retrieves the device manager singleton
Returns
the ClutterDeviceManager singleton. The returned instance is owned by Clutter and it should not be modified or freed.
[transfer none]
Since: 1.2
clutter_device_manager_list_devices ()
GSList *
clutter_device_manager_list_devices (ClutterDeviceManager *device_manager);
Lists all currently registered input devices
Returns
a newly allocated list of ClutterInputDevice objects. Use
g_slist_free() to deallocate it when done.
[transfer container][element-type Clutter.InputDevice]
Since: 1.2
clutter_device_manager_peek_devices ()
const GSList *
clutter_device_manager_peek_devices (ClutterDeviceManager *device_manager);
Lists all currently registered input devices
Returns
a pointer to the internal list of ClutterInputDevice objects. The returned list is owned by the ClutterDeviceManager and should never be modified or freed.
[transfer none][element-type Clutter.InputDevice]
Since: 1.2
clutter_device_manager_get_device ()
ClutterInputDevice * clutter_device_manager_get_device (ClutterDeviceManager *device_manager,gint device_id);
Retrieves the ClutterInputDevice with the given device_id
Returns
a ClutterInputDevice or NULL. The
returned device is owned by the ClutterDeviceManager and should
never be modified or freed.
[transfer none]
Since: 1.2
clutter_device_manager_get_core_device ()
ClutterInputDevice * clutter_device_manager_get_core_device (ClutterDeviceManager *device_manager,ClutterInputDeviceType device_type);
Retrieves the core ClutterInputDevice of type device_type
Core devices are devices created automatically by the default Clutter backend
Returns
a ClutterInputDevice or NULL. The
returned device is owned by the ClutterDeviceManager and should
not be modified or freed.
[transfer none]
Since: 1.2
clutter_get_input_device_for_id ()
ClutterInputDevice *
clutter_get_input_device_for_id (gint id_);
clutter_get_input_device_for_id has been deprecated since version 1.10 and should not be used in newly-written code.
Use clutter_device_manager_get_device() instead.
Retrieves the ClutterInputDevice from its id_
. This is a convenience
wrapper for clutter_device_manager_get_device() and it is functionally
equivalent to:
1 2 3 4 5 |
ClutterDeviceManager *manager; ClutterInputDevice *device; manager = clutter_device_manager_get_default (); device = clutter_device_manager_get_device (manager, id); |
Since: 0.8

Signal Details
The “device-added” signal
void user_function (ClutterDeviceManager *manager, ClutterInputDevice *device, gpointer user_data)
The ::device-added signal is emitted each time a device has been added to the ClutterDeviceManager
Parameters
manager |
the ClutterDeviceManager that emitted the signal |
|
device |
the newly added ClutterInputDevice |
|
user_data |
user data set when the signal handler was connected. |
Flags: Run Last
Since: 1.2
The “device-removed” signal
void user_function (ClutterDeviceManager *manager, ClutterInputDevice *device, gpointer user_data)
The ::device-removed signal is emitted each time a device has been removed from the ClutterDeviceManager
Parameters
manager |
the ClutterDeviceManager that emitted the signal |
|
device |
the removed ClutterInputDevice |
|
user_data |
user data set when the signal handler was connected. |
Flags: Run Last
Since: 1.2
