Struct rat_widget::viewport::Viewport

pub struct Viewport<'a, T> { /* private fields */ }

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

Implementations

impl<'a, T> Viewport<'a, T>

pub fn new(inner: T) -> Self

New viewport.

pub fn block(self, block: Block<'a>) -> Self

pub fn scroll(self, scroll: Scroll<'a>) -> Self

pub fn hscroll(self, scroll: Scroll<'a>) -> Self

pub fn vscroll(self, scroll: Scroll<'a>) -> Self

pub fn view_size(self, size: Size) -> Self

Size for the inner widget.

pub fn style(self, style: Style) -> Self

Style for the empty space outside the rendered buffer.

Trait Implementations

impl<'a, T: Clone> Clone for Viewport<'a, T>

fn clone(&self) -> Viewport<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug> Debug for Viewport<'a, T>

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

Formats the value using the given formatter.

impl<'a, T: Default> Default for Viewport<'a, T>

fn default() -> Viewport<'a, T>

Returns the “default value” for a type.

impl<'a, T> StatefulWidget for Viewport<'a, T>

where T: StatefulWidget,

type State = ViewportState<<T as StatefulWidget>::State>

State associated with the stateful widget.

fn render(self, area: Rect, buf: &mut Buffer, state: &mut Self::State)

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