Struct cursive::views::BoxView
[−]
[src]
pub struct BoxView<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
// Creates a 20x4 BoxView with a TextView content. let view = BoxView::with_fixed_size((20,4), TextView::new("Hello!"));
Methods
impl<T: View> BoxView<T>
[src]
fn new(width: SizeConstraint, height: SizeConstraint, view: T) -> Self
Creates a new BoxView
with the given width and height requirements.
None
values will use the wrapped view's preferences.
fn squishable(self) -> Self
Sets self
to be squishable.
A squishable BoxView
will take a smaller size than it should when
the available space is too small. In that case, it will allow the
child view to contract, if it can.
More specifically, if the available space is less than the size we would normally ask for, return the child size.
fn with_fixed_size<S: Into<Vec2>>(size: S, view: T) -> Self
Wraps view
in a new BoxView
with the given size.
fn with_fixed_width(width: usize, view: T) -> Self
Wraps view
in a new BoxView
with fixed width.
fn with_fixed_height(height: usize, view: T) -> Self
Wraps view
in a new BoxView
with fixed height.
fn with_full_screen(view: T) -> Self
Wraps view
in a BoxView
which will take all available space.
fn with_full_width(view: T) -> Self
Wraps view
in a BoxView
which will take all available width.
fn with_full_height(view: T) -> Self
Wraps view
in a BoxView
which will take all available height.
fn with_max_size<S: Into<Vec2>>(size: S, view: T) -> Self
Wraps view
in a BoxView
which will never be bigger than size
.
fn with_max_width(max_width: usize, view: T) -> Self
Wraps view
in a BoxView
which will enforce a maximum width.
The resulting width will never be more than max_width
.
fn with_max_height(max_height: usize, view: T) -> Self
Wraps view
in a BoxView
which will enforce a maximum height.
The resulting height will never be more than max_height
.
fn with_min_size<S: Into<Vec2>>(size: S, view: T) -> Self
Wraps view
in a BoxView
which will never be smaller than size
.
fn with_min_width(min_width: usize, view: T) -> Self
Wraps view
in a BoxView
which will enforce a minimum width.
The resulting width will never be less than min_width
.
fn with_min_height(min_height: usize, view: T) -> Self
Wraps view
in a BoxView
which will enforce a minimum height.
The resulting height will never be less than min_height
.
