pub struct WlDataDevice(_);
Implementations
introduce a new wl_data_offer
The data_offer event introduces a new wl_data_offer object, which will subsequently be used in either the data_device.enter event (for drag-and-drop) or the data_device.selection event (for selections). Immediately following the data_device_data_offer event, the new data_offer object will send out data_offer.offer events to describe the mime types it offers.
initiate drag-and-drop session
This event is sent when an active drag-and-drop pointer enters a surface owned by the client. The position of the pointer at enter time is provided by the x and y arguments, in surface-local coordinates.
end drag-and-drop session
This event is sent when the drag-and-drop pointer leaves the surface and the session ends. The client must destroy the wl_data_offer introduced at enter time at this point.
drag-and-drop session motion
This event is sent when the drag-and-drop pointer moves within the currently focused surface. The new position of the pointer is provided by the x and y arguments, in surface-local coordinates.
end drag-and-drop session successfully
The event is sent when a drag-and-drop operation is ended because the implicit grab is removed.
The drag-and-drop destination is expected to honor the last action received through wl_data_offer.action, if the resulting action is “copy” or “move”, the destination can still perform wl_data_offer.receive requests, and is expected to end all transfers with a wl_data_offer.finish request.
If the resulting action is “ask”, the action will not be considered final. The drag-and-drop destination is expected to perform one last wl_data_offer.set_actions request, or wl_data_offer.destroy in order to cancel the operation.
advertise new selection
The selection event is sent out to notify the client of a new wl_data_offer for the selection for this device. The data_device.data_offer and the data_offer.offer events are sent out immediately before this event to introduce the data offer object. The selection event is sent to a client immediately before receiving keyboard focus and when a new selection is set while the client has keyboard focus. The data_offer is valid until a new data_offer or NULL is received or until the client loses keyboard focus. Switching surface with keyboard focus within the same client doesn’t mean a new selection will be sent. The client must destroy the previous selection data_offer, if any, upon receiving this event.
