Provided Methods§
sourcefn operate(
&mut self,
_layout: Layout<'_>,
_operation: &mut dyn Operation<Message>
)
fn operate(
&mut self,
_layout: Layout<'_>,
_operation: &mut dyn Operation<Message>
)
Applies a widget::Operation
to the Overlay
.
sourcefn on_event(
&mut self,
_event: Event,
_layout: Layout<'_>,
_cursor_position: Point,
_renderer: &Renderer,
_clipboard: &mut dyn Clipboard,
_shell: &mut Shell<'_, Message>
) -> Status
fn on_event(
&mut self,
_event: Event,
_layout: Layout<'_>,
_cursor_position: Point,
_renderer: &Renderer,
_clipboard: &mut dyn Clipboard,
_shell: &mut Shell<'_, Message>
) -> Status
Processes a runtime Event
.
It receives:
- an
Event
describing user interaction - the computed
Layout
of theOverlay
- the current cursor position
- a mutable
Message
list, allowing theOverlay
to produce new messages based on user interaction. - the
Renderer
- a
Clipboard
, if available
By default, it does nothing.
sourcefn mouse_interaction(
&self,
_layout: Layout<'_>,
_cursor_position: Point,
_viewport: &Rectangle,
_renderer: &Renderer
) -> Interaction
fn mouse_interaction(
&self,
_layout: Layout<'_>,
_cursor_position: Point,
_viewport: &Rectangle,
_renderer: &Renderer
) -> Interaction
Returns the current mouse::Interaction
of the Overlay
.
By default, it returns mouse::Interaction::Idle
.
