Struct ControlBar 

pub struct ControlBar { /* private fields */ }

The floating bar of controls over media (a camera’s capture controls, a player’s transport): one floating Panel shaped to a row of Regular icon buttons, control_inset inside it so the buttons’ corners run concentric with the panel’s, s1 between them. It owns the panel, the gaps, the hover and press faces and the hit rects; the host says which controls stand in it and where, and acts on the index it reports.

Implementations

impl ControlBar

pub fn new() -> ControlBar

pub fn size(count: usize, theme: &Theme) -> (f64, f64)

The size of a bar of count controls.

pub fn bottom_centre(area: Rect, count: usize, theme: &Theme) -> Rect

Where a bar of count controls stands in area: centred, one content gutter above its bottom edge.

pub fn paint( &mut self, scene: &mut Scene, transform: Affine, text: &mut TextRenderer, theme: &Theme, rect: Rect, controls: &[BarControl<'_>], )

Paint the bar with controls at rect (from Self::size or Self::bottom_centre), and keep their hit rects.

pub fn rect(&self) -> Rect

The bar’s rect at the last paint.

pub fn control_rect(&self, index: usize) -> Option<Rect>

Control index’s rect at the last paint.

pub fn hit(&self, point: Point) -> Option<usize>

The control under point, if any.

pub fn contains(&self, point: Point) -> bool

Whether point is on the bar (a press there is the bar’s).

pub fn handle( &mut self, event: &WindowEvent, scale_factor: f64, ) -> Option<usize>

Route event; returns the control a click activated. A press on the bar but between controls is still the bar’s: check Self::contains to swallow it.
