Struct CustomNode

Source

pub struct CustomNode {
    pub widget: Rc<RefCell<dyn Widget>>,
}

Expand description

A node wrapping a user-defined custom widget.

Uses Rc<RefCell<dyn Widget>> because:

Rc enables Clone (View derives Clone) without requiring Widget: Clone
RefCell allows interior mutability for focus handling

Fields§

§widget: Rc<RefCell<dyn Widget>>
