Struct LogicalTreeAttachmentEventArgs 

pub struct LogicalTreeAttachmentEventArgs { /* private fields */ }

Holds the event arguments for the attached_to_logical_tree and detached_from_logical_tree events. The args are immutable: copies compare equal when they describe the same attachment (the same elements).

Implementations

impl LogicalTreeAttachmentEventArgs

pub fn new( root: Ref<StyledElement>, source: Ref<StyledElement>, parent: Option<Ref<StyledElement>>, ) -> Self

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

The root of the logical tree that the control is being attached to or detached from.

pub fn source(&self) -> &Ref<StyledElement>

The control that was attached or detached from the logical tree.

Logical tree attachment events travel down the tree, so this is the control at the top of the subtree that was attached or detached.

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

The control that the source is being attached to or detached from. For a detachment this is the old parent; None when the source is a logical root.
