[−][src]Struct cursive::views::BoxView
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]
pub fn new(width: SizeConstraint, height: SizeConstraint, view: T) -> Self
[src]
Creates a new BoxView
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)
[src]
Sets the size constraints for this view.
pub fn set_width(&mut self, width: SizeConstraint)
[src]
Sets the width constraint for this view.
Leaves the height unchanged.
pub fn set_height(&mut self, height: SizeConstraint)
[src]
Sets the height constraint for this view.
Leaves the width unchanged.
pub fn squishable(self) -> Self
[src]
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.
pub fn set_squishable(&mut self, squishable: bool)
[src]
Controls the "squishability" of self
.
pub fn with_fixed_size<S: Into<Vec2>>(size: S, view: T) -> Self
[src]
Wraps view
in a new BoxView
with the given size.
pub fn with_fixed_width(width: usize, view: T) -> Self
[src]
Wraps view
in a new BoxView
with fixed width.
pub fn with_fixed_height(height: usize, view: T) -> Self
[src]
Wraps view
in a new BoxView
with fixed height.
pub fn with_full_screen(view: T) -> Self
[src]
Wraps view
in a BoxView
which will take all available space.
pub fn with_full_width(view: T) -> Self
[src]
Wraps view
in a BoxView
which will take all available width.
pub fn with_full_height(view: T) -> Self
[src]
Wraps view
in a BoxView
which will take all available height.
pub fn with_max_size<S: Into<Vec2>>(size: S, view: T) -> Self
[src]
Wraps view
in a BoxView
which will never be bigger than size
.
pub fn with_max_width(max_width: usize, view: T) -> Self
[src]
Wraps view
in a BoxView
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
[src]
Wraps view
in a BoxView
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
[src]
Wraps view
in a BoxView
which will never be smaller than size
.
pub fn with_min_width(min_width: usize, view: T) -> Self
[src]
Wraps view
in a BoxView
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
[src]
Wraps view
in a BoxView
which will enforce a minimum height.
The resulting height will never be less than min_height
.
pub fn get_inner(&self) -> &T
[src]
Gets access to the inner view.
pub fn get_inner_mut(&mut self) -> &mut T
[src]
Gets mutable access to the inner view.
