Struct cursive_core::views::PaddedView

pub struct PaddedView<V> { /* private fields */ }

Adds padding to another view.

This view wraps another view and adds some padding.

The wrapped view will see a reduced space available.

Examples

// Adds 2 columns of padding to the left and to the right.

// lrtb = Left, Right, Top, Bottom
let view = PaddedView::lrtb(2, 2, 0, 0, TextView::new("Padded text"));
