Provided Methods

fn update_caret_position(&self)

Updates the position of the caret.

Implementations of the AccessibleText interface should call this function every time the caret has moved, in order to notify assistive technologies.

fn update_contents( &self, change: AccessibleTextContentChange, start: u32, end: u32, )

Notifies assistive technologies of a change in contents.

Implementations of the AccessibleText interface should call this function every time their contents change as the result of an operation, like an insertion or a removal.

Note: If the change is a deletion, this function must be called before removing the contents, if it is an insertion, it must be called after inserting the new contents.

change

the type of change in the contents

start

the starting offset of the change, in characters

end

the end offset of the change, in characters

fn update_selection_bound(&self)

Updates the boundary of the selection.

Implementations of the AccessibleText interface should call this function every time the selection has moved, in order to notify assistive technologies.

Dyn Compatibility

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
