Struct Image 

pub struct Image<'a> {
    pub style: Style,
    /* private fields */
}

Display a raw pixel buffer.

Fields

style: Style

Styling for the image background.

Implementations

impl<'a> Image<'a>

pub fn new(bounds: Rect, width: i32, height: i32, pixels: &'a [Color]) -> Self

Create an image widget backed by a slice of pixels.

pub fn with_blit_opts(self, blit_opts: BlitOpts) -> Self

Configure low-level blit options for this image instance.

pub fn set_pixels(&mut self, width: i32, height: i32, pixels: &'a [Color])

Replace the displayed pixel buffer and its dimensions at runtime.

The widget’s pixel buffer was previously construction-only. This setter exists so generated reactive bindings (QT-05g PredicateBinding) can swap artwork as a state machine’s predicates change, without rebuilding the widget tree. The blit options (e.g. a stretch scale) are left unchanged — callers that swap to a differently-sized buffer and need a different scale must also call set_blit_opts.

pub fn set_blit_opts(&mut self, blit_opts: BlitOpts)

Replace the low-level blit options at runtime (companion to set_pixels when the new buffer differs in size).

pub fn set_hidden(&mut self, hidden: bool)

Hide or show the image at runtime. A hidden image’s draw is a no-op — it paints nothing (not even its background), leaving whatever is behind it visible. Generated reactive bindings (QT-05h VisibilityBinding) use this to drive a widget’s visibility from a state-machine predicate without removing it from the widget tree.

pub fn is_hidden(&self) -> bool

Whether the image is currently hidden.

Trait Implementations

impl<'a> Widget for Image<'a>

fn handle_event(&mut self, _event: &Event) -> bool

Images are purely visual and do not handle events.

fn bounds(&self) -> Rect

Return the area this widget occupies relative to its parent.

fn draw(&self, renderer: &mut dyn Renderer)

Render the widget using the provided Renderer.

fn clear_region(&mut self) -> Option<Rect>

Return a region (in draw/landscape coordinates) that should be restored from the pristine background copy, or None.

fn set_bounds(&mut self, _bounds: Rect)

Called by the LPAR-10 layout pass to notify this widget of its layout-computed bounds.

fn widget_font_mut(&mut self) -> Option<&mut WidgetFont>

Expose this widget’s font slot for cascade-driven font resolution (FONT-05 §5.B).
