Struct rat_widget::scrolled::View

pub struct View<T> { /* private fields */ }

View has its own size, and can contain a stateless widget that will be rendered to a view sized buffer. This buffer is then offset and written to the actual frame buffer.

Implementations

impl<T> View<T>

pub fn new(inner: T) -> View<T>

New view.

pub fn view_size(self, size: Size) -> View<T>

Size for the inner widget.

pub fn style(self, style: Style) -> View<T>

Style for the empty space outside the rendered buffer.

Trait Implementations

impl<T> Clone for View<T>

where T: Clone,

fn clone(&self) -> View<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for View<T>

where T: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T> Default for View<T>

where T: Default,

fn default() -> View<T>

Returns the “default value” for a type.

impl<State, T> ScrollingWidget<State> for View<T>

where T: Widget,

fn need_scroll(&self, area: Rect, _state: &mut State) -> (bool, bool)

Widget wants a (horizontal, vertical) scrollbar. This gets combined with the ScrollbarPolicy.

impl<T> StatefulWidget for View<T>

where T: Widget,

type State = ViewState

State associated with the stateful widget.

fn render( self, area: Rect, buf: &mut Buffer, state: &mut <View<T> as StatefulWidget>::State, )

Draws the current state of the widget in the given buffer. That is the only method required to implement a custom stateful widget.

impl<T> StatefulWidgetRef for View<T>

where T: WidgetRef,

type State = ViewState

State associated with the stateful widget.

fn render_ref( &self, area: Rect, buf: &mut Buffer, state: &mut <View<T> as StatefulWidgetRef>::State, )

Draws the current state of the widget in the given buffer. That is the only method required to implement a custom stateful widget.
