A status bar widget that can be rendered using a DrawContext

Required methods

pub fn draw(
    &mut self,
    ctx: &mut dyn DrawContext,
    screen: usize,
    screen_has_focus: bool,
    w: f64,
    h: f64
) -> Result<()>

Render the current state of the widget to the status bar window.

pub fn current_extent(
    &mut self,
    ctx: &mut dyn DrawContext,
    h: f64
) -> Result<(f64, f64)>

Current required width and height for this widget due to its content

pub fn require_draw(&self) -> bool

Does this widget currently require re-rendering? (should be updated when 'draw' is called)

pub fn is_greedy(&self) -> bool

If true, this widget will expand to fill remaining available space after layout has been computed. If multiple greedy widgets are present in a given StatusBar then the available space will be split evenly between all widgets.
