Struct cursive_core::views::OnLayoutView

pub struct OnLayoutView<V> { /* fields omitted */ }

View wrapper overriding the View::layout method.

Implementations

impl<V> OnLayoutView<V>

pub fn new<F>(view: V, on_layout: F) -> Self where
    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::{
    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));

pub fn wrap(view: V) -> Self 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.

pub fn set_on_layout<F>(&mut self, on_layout: F) where
    F: FnMut(&mut V, Vec2) + 'static, 

Replaces the callback to run.

pub fn get_inner(&self) -> &V

Gets access to the inner view.

pub fn get_inner_mut(&mut self) -> &mut V

Gets mutable access to the inner view.
