pub fn set_editing_state( self: Handle<Self>, app: &mut App, value: TextEditingValue, )

Requests that the text input control change its internal state to match the given state.

pub fn set_editable_size_and_transform( self: Handle<Self>, app: &mut App, editable_box_size: Size, transform: Matrix4, )

Send the size and transform of the editable text to engine.

1. editable_box_size: size of the render editable box.

2. transform: a matrix that maps the local paint coordinate system to the PipelineOwner.rootNode.

pub fn set_composing_rect(self: Handle<Self>, app: &mut App, rect: Rect)

If any of the 4 coordinates of the given Rect is not finite, a Rect of size (-1, -1) will be sent instead.

pub fn set_caret_rect(self: Handle<Self>, app: &mut App, rect: Rect)
