Image

Struct Image 

Source
pub struct Image { /* private fields */ }
Expand description

An image widget. Pretty self-explanatory.

See the image example for how to use it in practice.

§Theming

The widget itself only draws the underlying image, so theming is useless.

Implementations§

Source§

impl Image

Source

pub fn new(image: impl Into<MaybeSignal<ImageData>>) -> Self

Create an image widget from the given ImageData.

Source

pub fn with_image(self, image: impl Into<MaybeSignal<ImageData>>) -> Self

Set the image.

Trait Implementations§

Source§

impl Widget for Image

Source§

fn render( &mut self, scene: &mut dyn Scene, _: &mut dyn Theme, layout_node: &LayoutNode, _: &AppInfo, _: AppContext, )

Render the widget to the canvas.
Source§

fn layout_style(&self) -> StyleNode

Return the layout style node for layout computation.
Source§

fn update(&mut self, _: &LayoutNode, _: AppContext, _: &AppInfo) -> Update

Update the widget state with given info and layout. Returns if the app should be updated.
Source§

fn widget_id(&self) -> WidgetId

Return the widget id.
Source§

impl WidgetLayoutExt for Image

Source§

fn set_layout_style( &mut self, layout_style: impl Into<MaybeSignal<LayoutStyle>>, )

Sets the layout style of the widget.
Source§

fn with_layout_style( self, layout_style: impl Into<MaybeSignal<LayoutStyle>>, ) -> Self
where Self: Sized,

Sets the layout style of the widget and returns self.

Immutably borrows from an owned value. Read more

Source§

impl<T> Downcast for T
where T: Any,

Source§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
Source§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
Source§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
Source§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
Source§

Source§

fn from(t: T) -> T

Returns the argument unchanged.

Source§

Source§

impl<T, U> Into<U> for T

Source§

fn is_in_subset(&self) -> bool

Source§

fn to_subset_unchecked(&self) -> SS

Use with care! Same as self.to_subset but without any property checks. Always succeeds.
Source§

fn from_subset(element: &SS) -> SP

The inclusion map: converts self to the equivalent element of its superset.
