[−][src]Struct cursive::views::CircularFocus
Adds circular focus to a wrapped view.
Wrap a view in CircularFocus
to enable wrap-around focus
(when the focus exits this view, it will come back the other side).
It can be configured to wrap Tab (and Shift+Tab) keys, and/or Arrow keys.
Methods
impl<T: View> CircularFocus<T>
[src]
pub fn new(view: T, wrap_tab: bool, wrap_arrows: bool) -> Self
[src]
Creates a new CircularFocus
around the given view.
If wrap_tab
is true, Tab keys will cause focus to wrap around.
If wrap_arrows
is true, Arrow keys will cause focus to wrap around.
pub fn wrap_tab(view: T) -> Self
[src]
Creates a new CircularFocus
view which will wrap around Tab-based
focus changes.
Whenever Tab
would leave focus from this view, the focus will be
brought back to the beginning of the view.
pub fn wrap_arrows(view: T) -> Self
[src]
Creates a new CircularFocus
view which will wrap around Tab-based
focus changes.
Whenever an arrow key
pub fn wraps_tab(&self) -> bool
[src]
Returns true
if Tab key cause focus to wrap around.
pub fn wraps_arrows(&self) -> bool
[src]
Returns true
if Arrow keys cause focus to wrap around.
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.
