[−][src]Struct cursive_core::views::OnLayoutView
View wrapper overriding the View::layout
method.
Implementations
impl<V> OnLayoutView<V>
[src]
pub fn new<F>(view: V, on_layout: F) -> Self where
F: FnMut(&mut V, Vec2) + 'static,
[src]
F: FnMut(&mut V, Vec2) + 'static,
Wraps a view in an OnLayoutView
.
Will run the given closure for layout instead of the one from view
.
use cursive_core::{View, views::{TextView, OnLayoutView}}; let view = TextView::new("foo"); // Here we just run the innver view's layout. OnLayoutView::new(view, |v, s| v.layout(s));
pub fn wrap(view: V) -> Self where
V: View,
[src]
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
.
pub fn set_on_layout<F>(&mut self, on_layout: F) where
F: FnMut(&mut V, Vec2) + 'static,
[src]
F: FnMut(&mut V, Vec2) + 'static,
Replaces the callback to run.
pub fn get_inner(&self) -> &V
[src]
Gets access to the inner view.
pub fn get_inner_mut(&mut self) -> &mut V
[src]
Gets mutable access to the inner view.
