Fields

start_drag: fn(_: &mut EventLoopHandle, _: &mut ID, _: &Client, _: &WlDataDevice, _: Option<&WlDataSource>, _: &WlSurface, _: Option<&WlSurface>, _: u32)

start drag-and-drop operation

This request asks the compositor to start a drag-and-drop operation on behalf of the client.

The source argument is the data source that provides the data for the eventual data transfer. If source is NULL, enter, leave and motion events are sent only to the client that initiated the drag and the client is expected to handle the data passing internally.

The origin surface is the surface where the drag originates and the client must have an active implicit grab that matches the serial.

The icon surface is an optional (can be NULL) surface that provides an icon to be moved around with the cursor. Initially, the top-left corner of the icon surface is placed at the cursor hotspot, but subsequent wl_surface.attach request can move the relative position. Attach requests must be confirmed with wl_surface.commit as usual. The icon surface is given the role of a drag-and-drop icon. If the icon surface already has another role, it raises a protocol error.

The current and pending input regions of the icon wl_surface are cleared, and wl_surface.set_input_region is ignored until the wl_surface is no longer used as the icon surface. When the use as an icon ends, the current and pending input regions become undefined, and the wl_surface is unmapped.

Arguments: event_queue_handle, interface_data, wl_data_device, source, origin, icon, serial

set_selection: fn(_: &mut EventLoopHandle, _: &mut ID, _: &Client, _: &WlDataDevice, _: Option<&WlDataSource>, _: u32)

copy data to the selection

This request asks the compositor to set the selection to the data from the source on behalf of the client.

To unset the selection, set the source to NULL.

Arguments: event_queue_handle, interface_data, wl_data_device, source, serial

release: fn(_: &mut EventLoopHandle, _: &mut ID, _: &Client, _: &WlDataDevice)

destroy data device

This request destroys the data device.

Arguments: event_queue_handle, interface_data, wl_data_device

This is a destructor, you cannot send events to this object once this method is called.

This event only exists since version 2 of the interface
