Struct VisualTreeAttachmentEventArgs 

pub struct VisualTreeAttachmentEventArgs { /* private fields */ }

Holds the event arguments for the attached_to_visual_tree and detached_from_visual_tree events.

Implementations

impl VisualTreeAttachmentEventArgs

pub fn new( attachment_point: Option<Ref<Visual>>, presentation_source: Rc<dyn IPresentationSource>, ) -> Self

Panics if the presentation source has no root visual.

pub fn attachment_point(&self) -> Option<&Ref<Visual>>

The parent that the visual’s tree is being attached to or detached from. None when the presentation source’s root visual itself is being attached or detached.

pub fn parent(&self) -> Option<&Ref<Visual>>

👎Deprecated:

Use attachment_point

The parent that the visual’s tree is being attached to or detached from.

pub fn presentation_source(&self) -> &Rc<dyn IPresentationSource>

The presentation source that the visual is being attached to or detached from.

pub fn root(&self) -> &Ref<Visual>

👎Deprecated:

This was previously always returning TopLevel. This is no longer guaranteed. Use TopLevel::get_top_level(visual) if you need a TopLevel or root_visual if you are interested in the root of the visual tree.

The root visual of the tree.

pub fn root_visual(&self) -> &Ref<Visual>

The root visual of the tree this visual is being attached to or detached from: the root visual of the presentation source.

pub fn set_root_visual(&mut self, value: Ref<Visual>)
