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, x: f64, y: f64, wl_surface: &WlSurface, )

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, x: f64, y: f64, )

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”.

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.
