Struct cursive::views::OnLayoutView [−][src]
pub struct OnLayoutView<V> { /* fields omitted */ }
Expand description
View wrapper overriding the View::layout
method.
Implementations
Wraps a view in an OnLayoutView
.
Will run the given closure for layout instead of the one from view
.
use cursive_core::{
views::{OnLayoutView, TextView},
View,
};
let view = TextView::new("foo");
// Here we just run the innver view's layout.
OnLayoutView::new(view, |v, s| v.layout(s));
Wraps a view in an OnLayoutView
.
This is a shortcut for Self::new(view, V::layout)
You can change it later with set_on_layout
.
Replaces the callback to run.
Gets mutable access to the inner view.
