Struct cursive::views::ResizedView

pub struct ResizedView<T: View> { /* fields omitted */ }

Wrapper around another view, with a controlled size.

Each axis can independently be set to:

• Keep a fixed size
• Use all available size
• Use at most a given size
• Use at least a given size
• Let the wrapped view decide.

Examples

use cursive::views::{ResizedView, TextView};

// Creates a 20x4 ResizedView with a TextView content.
let view = ResizedView::with_fixed_size((20,4), TextView::new("Hello!"));

See also Boxable for an easy way to wrap any view.

Methods

impl<T: View> ResizedView<T>

pub fn new(width: SizeConstraint, height: SizeConstraint, view: T) -> Self

Creates a new ResizedView with the given width and height requirements.

None values will use the wrapped view's preferences.

pub fn set_constraints(&mut self, width: SizeConstraint, height: SizeConstraint)

Sets the size constraints for this view.

pub fn set_width(&mut self, width: SizeConstraint)

Sets the width constraint for this view.

Leaves the height unchanged.

pub fn set_height(&mut self, height: SizeConstraint)

Sets the height constraint for this view.

Leaves the width unchanged.

pub fn with_fixed_size<S: Into<Vec2>>(size: S, view: T) -> Self

Wraps view in a new ResizedView with the given size.

pub fn with_fixed_width(width: usize, view: T) -> Self

Wraps view in a new ResizedView with fixed width.

pub fn with_fixed_height(height: usize, view: T) -> Self

Wraps view in a new ResizedView with fixed height.

pub fn with_full_screen(view: T) -> Self

Wraps view in a ResizedView which will take all available space.

pub fn with_full_width(view: T) -> Self

Wraps view in a ResizedView which will take all available width.

pub fn with_full_height(view: T) -> Self

Wraps view in a ResizedView which will take all available height.

pub fn with_max_size<S: Into<Vec2>>(size: S, view: T) -> Self

Wraps view in a ResizedView which will never be bigger than size.

pub fn with_max_width(max_width: usize, view: T) -> Self

Wraps view in a ResizedView which will enforce a maximum width.

The resulting width will never be more than max_width.

pub fn with_max_height(max_height: usize, view: T) -> Self

Wraps view in a ResizedView which will enforce a maximum height.

The resulting height will never be more than max_height.

pub fn with_min_size<S: Into<Vec2>>(size: S, view: T) -> Self

Wraps view in a ResizedView which will never be smaller than size.

pub fn with_min_width(min_width: usize, view: T) -> Self

Wraps view in a ResizedView which will enforce a minimum width.

The resulting width will never be less than min_width.

pub fn with_min_height(min_height: usize, view: T) -> Self

Wraps view in a ResizedView which will enforce a minimum height.

The resulting height will never be less than min_height.

pub fn get_inner(&self) -> &T

Gets access to the inner view.

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

Gets mutable access to the inner view.
