Required Methods§
sourcefn offer<'a>(
ctx: &'a mut Ctx,
object_id: u32,
mime_type: Str<'a>
) -> Self::OfferFut<'a>
fn offer<'a>( ctx: &'a mut Ctx, object_id: u32, mime_type: Str<'a> ) -> Self::OfferFut<'a>
add an offered mime type
This request adds a mime type to the set of mime types advertised to targets. Can be called several times to offer multiple types.
sourcefn destroy<'a>(ctx: &'a mut Ctx, object_id: u32) -> Self::DestroyFut<'a>
fn destroy<'a>(ctx: &'a mut Ctx, object_id: u32) -> Self::DestroyFut<'a>
destroy the data source
Destroy the data source.
sourcefn set_actions<'a>(
ctx: &'a mut Ctx,
object_id: u32,
dnd_actions: DndAction
) -> Self::SetActionsFut<'a>
fn set_actions<'a>( ctx: &'a mut Ctx, object_id: u32, dnd_actions: DndAction ) -> Self::SetActionsFut<'a>
set the available drag-and-drop actions
Sets the actions that the source side client supports for this operation. This request may trigger wl_data_source.action and wl_data_offer.action events if the compositor needs to change the selected action.
The dnd_actions argument must contain only values expressed in the wl_data_device_manager.dnd_actions enum, otherwise it will result in a protocol error.
This request must be made once only, and can only be made on sources used in drag-and-drop, so it must be performed before wl_data_device.start_drag. Attempting to use the source other than for drag-and-drop will raise a protocol error.
