Handler trait for DataDevice events.

The functions defined in this trait are called as DataDevice events are received from the compositor.

Required Methods

fn enter( &mut self, conn: &Connection, qh: &QueueHandle<Self>, data_device: &WlDataDevice, )

The data device pointer has entered a surface at the provided location

fn leave( &mut self, conn: &Connection, qh: &QueueHandle<Self>, data_device: &WlDataDevice, )

The drag and drop pointer has left the surface and the session ends. The offer will be destroyed unless it was previously dropped. In the case of a dropped offer, the client must destroy it manually after it is finished.

fn motion( &mut self, conn: &Connection, qh: &QueueHandle<Self>, data_device: &WlDataDevice, )

Drag and Drop motion.

fn selection( &mut self, conn: &Connection, qh: &QueueHandle<Self>, data_device: &WlDataDevice, )

Advertises a new selection.

fn drop_performed( &mut self, conn: &Connection, qh: &QueueHandle<Self>, data_device: &WlDataDevice, )

Drop performed. After the next data offer action event, data may be able to be received, unless the action is “ask”.

Object Safety

This trait is not object safe.
