Struct cursive::views::OnLayoutView
source · [−]pub struct OnLayoutView<V> { /* private fields */ }
Expand description
View wrapper overriding the View::layout
method.
Implementations
sourceimpl<V> OnLayoutView<V>
impl<V> OnLayoutView<V>
sourcepub fn new<F>(view: V, on_layout: F) -> OnLayoutView<V>where
F: 'static + FnMut(&mut V, XY<usize>),
pub fn new<F>(view: V, on_layout: F) -> OnLayoutView<V>where
F: 'static + FnMut(&mut V, XY<usize>),
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));
sourcepub fn wrap(view: V) -> OnLayoutView<V>where
V: View,
pub fn wrap(view: V) -> OnLayoutView<V>where
V: View,
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
.
sourcepub fn set_on_layout<F>(&mut self, on_layout: F)where
F: 'static + FnMut(&mut V, XY<usize>),
pub fn set_on_layout<F>(&mut self, on_layout: F)where
F: 'static + FnMut(&mut V, XY<usize>),
Replaces the callback to run.
sourcepub fn get_inner_mut(&mut self) -> &mut V
pub fn get_inner_mut(&mut self) -> &mut V
Gets mutable access to the inner view.
