Struct cursive::views::ScreensView [−][src]
pub struct ScreensView<V = BoxedView> { /* fields omitted */ }
Expand description
A view that can switch between different screens.
Implementations
Creates a new empty ScreensView
.
Creates a new ScreensView
with a single screen.
Returns a reference to the currently active screen.
Returns None
if there is no active screen.
Returns a mutable reference to the currently active screen.
Returns the id of the currently active screen.
Adds a new screen, and returns its ID.

Draws the background.

View::draw
.
