Struct cursive_core::views::HideableView

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

Wrapper around another view that can be hidden at will.

By default, it simply forwards all calls to the inner view.

When hidden (with HideableView::hide()), it will appear as a zero-sized invisible view, will not take focus and will not accept input.

It can be made visible again with HideableView::unhide().

Implementations

impl<V> HideableView<V>

pub fn new(view: V) -> Self

Creates a new HideableView around view.

It will be visible by default.

pub fn set_visible(&mut self, visible: bool)

Sets the visibility for this view.

pub fn hide(&mut self)

Sets the visibility for this view to false.

pub fn unhide(&mut self)

Sets the visibility for this view to true.

pub fn hidden(self) -> Self

Sets the visibility for this view to false.

Chainable variant.

pub fn visible(self, flag: bool) -> Self

Sets the visibility for this view to flag value. Useful when creating views needs to be decided at runtime. Chainable variant.

pub fn is_visible(&self) -> bool

Returns true if the wrapped view is going to be visible.

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.
