Provided Methods§

Source

fn render(this: &Self, context: &mut DrawingContext<'_>)

Renders the visual to a drawing context.

Source

fn on_attached_to_visual_tree_core( this: &Self, e: &VisualTreeAttachmentEventArgs, )

Calls the on_attached_to_visual_tree method for this control and all of its visual descendants.

Source

fn on_detached_from_visual_tree_core( this: &Self, e: &VisualTreeAttachmentEventArgs, )

Calls the on_detached_from_visual_tree method for this control and all of its visual descendants.

Source

fn on_attached_to_visual_tree(this: &Self, e: &VisualTreeAttachmentEventArgs)

Called when the control is added to a rooted visual tree.

Source

fn on_detached_from_visual_tree(this: &Self, e: &VisualTreeAttachmentEventArgs)

Called when the control is removed from a rooted visual tree.

Source

fn on_visual_parent_changed( this: &Self, old_parent: Option<&Ref<Visual>>, new_parent: Option<&Ref<Visual>>, )

Called when the control’s visual parent changes.

Source

fn bypass_flow_direction_policies(this: &Self) -> bool

Whether the control ignores the flow direction policies, i.e. is never mirrored.

Source

fn invalidate_mirror_transform(this: &Self)

Computes the has_mirror_transform value according to the flow direction of this visual and its parent.

Source

fn clip_to_bounds_radius(this: &Self) -> Option<CornerRadius>

The corner radius the visual clips its content with when clip_to_bounds is set; None for a plain rectangular clip. (Upstream: the IVisualWithRoundRectClip interface.)

Source

fn custom_hit_test(this: &Self, point: Point) -> Option<bool>

The custom hit test of the visual at a point in its own coordinates; None when the visual has none and is hit by what it occupies or draws. (Upstream: the ICustomHitTest interface; a class implementing it overrides this and the geometry form.)

Source

fn custom_hit_test_geometry( this: &Self, geometry: &Ref<Geometry>, ) -> Option<IntersectionResult>

The custom hit test of the visual against a geometry in its own coordinates; None when the visual has none.

Source

fn ensure_initialized_for_visual_brush(this: &Self)

Ensures that the visual is ready to use as the visual in a visual brush. (Upstream: the IVisualBrushInitialize interface; a class implementing it overrides this.)
