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", so this trait is not object safe.
