Trait RoleCx 

pub trait RoleCx {
    // Required method
    fn set_label_impl(&mut self, label: TextOrSource<'_>);
}

Context through which additional role properties may be specified

Unlike other widget method contexts, this is a trait; the caller provides an implementation.

Required Methods

fn set_label_impl(&mut self, label: TextOrSource<'_>)

Attach a label

Do not use this for Role::Label and similar items where the label is the widget’s primary value. Do use this where a label exists which is not the primary value, for example an image’s alternate text or a label next to a control.
