Struct cursive::views::ResizedView
source · [−]pub struct ResizedView<T> { /* private fields */ }
Expand description
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_core::views::{ResizedView, TextView};
// Creates a 20x4 ResizedView with a TextView content.
let view = ResizedView::with_fixed_size((20, 4), TextView::new("Hello!"));
See also Resizable
for an easy way to wrap any view.
Implementations

impl<T> ResizedView<T>
sourcepub fn new(
width: SizeConstraint,
height: SizeConstraint,
view: T
) -> ResizedView<T>
pub fn new(
width: SizeConstraint,
height: SizeConstraint,
view: T
) -> ResizedView<T>

with the given width and height requirements.
None
values will use the wrapped view’s preferences.

pub fn with_min_size<S>(size: S, view: T) -> ResizedView<T>where
S: Into<XY<usize>>,
Wraps view
in a ResizedView
which will never be smaller than size
.
As long as the parent view is large enough.
If the space is constrained (for example the window is too small), this view might still be given a smaller size than requested.
sourcepub fn with_min_width(min_width: usize, view: T) -> ResizedView<T>
pub fn with_min_width(min_width: usize, view: T) -> ResizedView<T>
