Trait Implementations

impl Default for ProgressWidget

fn default() -> ProgressWidget

Returns the "default value" for a type.

impl Widget for ProgressWidget

Implementation for drawing a ProgressWidget, with the Widget trait objects applied.

fn properties(&mut self) -> &mut WidgetProperties

This provides access to the WidgetProperties set for a Widget. These must be defined in the structure of the Widget, as they allow for direct manipulation of the properties.

fn draw(
    &mut self,
    c: &mut Canvas<Window>,
    _t: &mut TextureCache
) -> Option<&Texture>

Draws the ProgressWidget using the following properties:

• PROPERTY_MAIN_COLOR: the Color of the body of the Widget
• PROPERTY_BORDER_WIDTH: the width of the border to draw
• PROPERTY_BORDER_COLOR: the Color of the border.
• PROPERTY_PROGRESS_COLOR: the Color of the progress bar
• PROPERTY_PROGRESS: the progress value (from 0 to 100)

fn handle_event(&mut self, _e: PushrodEvent) -> Option<PushrodEvent>

Handles a PushrodEvent sent to the Widget that would also be sent to the application. If any PushrodEvents trigger a custom Widget-based event, this function can intercept the incoming event, and issue one of its own. If the function returns no events, a None can be returned, otherwise a Some(PushrodEvent) should be returned. If this function returns an event, that event will be sent on to the application as soon as it has been generated.

fn invalidate(&mut self)

Set the invalidation key for this Widget, indicating that the TextureCache needs to be redrawn.

fn invalidated(&mut self) -> bool

Flag indicating whether or not the draw method needs to be called for this Widget so that its TextureCache is refreshed.
