Trait containing all DeviceManager methods.

§Implementors

DeviceManager

Required Methods§

Source

fn get_core_device(&self, device_type: InputDeviceType) -> Option<InputDevice>

Retrieves the core InputDevice of type device_type

Core devices are devices created automatically by the default Clutter backend

§device_type

the type of the core device

§Returns

a InputDevice or None. The returned device is owned by the DeviceManager and should not be modified or freed

Source

fn get_device(&self, device_id: i32) -> Option<InputDevice>

Retrieves the InputDevice with the given device_id

§device_id

the integer id of a device

§Returns

a InputDevice or None. The returned device is owned by the DeviceManager and should never be modified or freed

Source

fn list_devices(&self) -> Vec<InputDevice>

Lists all currently registered input devices

§Returns

a newly allocated list of InputDevice objects. Use glib::SList::free to deallocate it when done

Source

fn peek_devices(&self) -> Vec<InputDevice>

Lists all currently registered input devices

§Returns

a pointer to the internal list of InputDevice objects. The returned list is owned by the DeviceManager and should never be modified or freed

Source

fn get_property_backend(&self) -> Option<Backend>

Source

fn connect_device_added<F: Fn(&Self, &InputDevice) + 'static>( &self, f: F, ) -> SignalHandlerId

The ::device-added signal is emitted each time a device has been added to the DeviceManager

§device

the newly added InputDevice

Source

fn connect_device_removed<F: Fn(&Self, &InputDevice) + 'static>( &self, f: F, ) -> SignalHandlerId

The ::device-removed signal is emitted each time a device has been removed from the DeviceManager

§device

the removed InputDevice

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
