impl<S> Oval<S>

pub fn resolution(self, resolution: usize) -> Oval<S>

The number of lines used to draw the edge.

By default, DEFAULT_RESOLUTION is used.

pub fn section(self, radians: f64) -> Oval<Section>

Produces an Oval where only a section is drawn.

The given radians describes the angle occuppied by the section's circumference.

impl Oval<Section>

pub fn offset_radians(self, offset_radians: f64) -> Oval<Section>

impl<S> Widget for Oval<S> where
    S: OvalSection, 

type State = State<S>

State to be stored within the Uis widget cache.

type Style = Style

Every widget is required to have its own associated Style type. This type is intended to contain high-level styling information for the widget that can be optionally specified by a user of the widget.

type Event = ()

The type of event yielded by the widget, returned via the Widget::set function.

fn init_state(&self, Generator) -> <Oval<S> as Widget>::State

Return the initial State of the Widget.

fn style(&self) -> <Oval<S> as Widget>::Style

Return the styling of the widget.

fn is_over(&self) -> fn(&Container, [f64; 2], &Theme) -> IsOver

Returns either of the following:

fn update(self, args: UpdateArgs<Oval<S>>) -> <Oval<S> as Widget>::Event

Update our Widget's unique Widget::State via the State wrapper type (the state field within the UpdateArgs).

fn default_x_position(&self, ui: &Ui) -> Position

The default Position for the widget along the x axis.

fn default_y_position(&self, ui: &Ui) -> Position

The default Position for the widget along the y axis.

fn default_x_dimension(&self, ui: &Ui) -> Dimension

The default width for the Widget.

fn default_y_dimension(&self, ui: &Ui) -> Dimension

The default height of the widget.

fn drag_area(
    &self,
    _dim: [f64; 2],
    _style: &Self::Style,
    _theme: &Theme
) -> Option<Rect>

If the widget is draggable, implement this method and return the position and dimensions of the draggable space. The position should be relative to the center of the widget.

fn kid_area(&self, args: KidAreaArgs<Self>) -> KidArea

The area on which child widgets will be placed when using the Place Position methods.

fn parent(self, parent_id: NodeIndex<u32>) -> Self
