Expand description
Handler trait for DataDevice events.
The functions defined in this trait are called as DataDevice events are received from the compositor.
Required Methods§
sourcefn enter(
&mut self,
conn: &Connection,
qh: &QueueHandle<Self>,
data_device: &WlDataDevice,
x: f64,
y: f64,
wl_surface: &WlSurface,
)
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
sourcefn leave(
&mut self,
conn: &Connection,
qh: &QueueHandle<Self>,
data_device: &WlDataDevice,
)
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.
sourcefn motion(
&mut self,
conn: &Connection,
qh: &QueueHandle<Self>,
data_device: &WlDataDevice,
x: f64,
y: f64,
)
fn motion( &mut self, conn: &Connection, qh: &QueueHandle<Self>, data_device: &WlDataDevice, x: f64, y: f64, )
Drag and Drop motion.
sourcefn selection(
&mut self,
conn: &Connection,
qh: &QueueHandle<Self>,
data_device: &WlDataDevice,
)
fn selection( &mut self, conn: &Connection, qh: &QueueHandle<Self>, data_device: &WlDataDevice, )
Advertises a new selection.
sourcefn drop_performed(
&mut self,
conn: &Connection,
qh: &QueueHandle<Self>,
data_device: &WlDataDevice,
)
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”.
Object Safety§
This trait is not object safe.
