Struct Clear 

pub struct Clear;

A widget to clear/reset a certain area to allow overdrawing (e.g. for popups).

This widget cannot be used to clear the terminal on the first render as tui assumes the render area is empty. Use crate::Terminal::clear instead.

Examples

fn draw_on_clear<B: Backend>(f: &mut Frame<B>, area: Rect) {
    let block = Block::default().title("Block").borders(Borders::ALL);
    f.render_widget(Clear, area); // <- this will clear/reset the area first
    f.render_widget(block, area); // now render the block widget
}

Popup Example

For a more complete example how to utilize Clear to realize popups see the example examples/popup.rs
