Handler trait for DataSource events.

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

Required Methods

fn accept_mime( &mut self, conn: &Connection, qh: &QueueHandle<Self>, source: &WlDataSource, mime: Option<String> )

This may be called multiple times, once for each accepted mime type from the destination, if any.

fn send_request( &mut self, conn: &Connection, qh: &QueueHandle<Self>, source: &WlDataSource, mime: String, fd: WritePipe )

The client has requested the data for this source to be sent. Send the data, then close the fd.

fn cancelled( &mut self, conn: &Connection, qh: &QueueHandle<Self>, source: &WlDataSource )

The data source is no longer valid Cleanup & destroy this resource

fn dnd_dropped( &mut self, conn: &Connection, qh: &QueueHandle<Self>, source: &WlDataSource )

A drop was performed. The data source will be used and should not be destroyed yet

fn dnd_finished( &mut self, conn: &Connection, qh: &QueueHandle<Self>, source: &WlDataSource )

The drag and drop finished. The data source may be destroyed.

fn action( &mut self, conn: &Connection, qh: &QueueHandle<Self>, source: &WlDataSource, action: DndAction )

An action was selected by the compositor.
