Render Commands

Classes¶

Page
ui::AnimatedIconSource	AnimatedIcon's source interface: an AnimatedVisualSource with named markers, each mapping a state name (such as "PointerOver") to the normalized progress point of that state's pose.
ui::AnimatedVisualSource	The content an AnimatedVisualPlayer plays: an animation with a fixed size and length whose render_frame() draws any point of it through Renderer.
ui::Bitmap	A CPU bitmap, 4 bytes per pixel: RGBA with straight alpha unless made in another PixelFormat.
ui::ClipScope	Pushes a clip when it is made and pops it when it goes out of scope, so an early return cannot leave the clip pushed.
ui::ContextMenuHost	Shows a context menu drawn by the system on a control's behalf.
ui::FontName	A font family name kept inline, so whatever holds one owns its copy: a name taken from a `std::string` stays valid after the string is gone.
ui::GradientStops	The stops of a gradient brush, in order: a list kept inside the brush up to four stops, so handing a theme's gradient to a control or a renderer allocates nothing.
ui::IconSource	An icon as a value: a glyph, a symbol, a path or a picture, held by whatever shows an icon without hosting it as a child element.
ui::ImageSource	What an Image element shows: a still Bitmap, an AnimatedImage or an SvgImage, held by value.
ui::NativeHost	The interface between a NativeControl, a leaf wrapping a real Win32 child window such as RichEdit, a shell control or WebView2, and whatever owns the real HWND.
ui::OpacityLayerScope	Pushes an opacity layer when it is made and pops it when it goes out of scope.
ui::PathGeometry	A set of figures and the fill rule between them: what a Path, a path icon or any other Shape draws.
ui::Renderer	The drawing surface every Element::render() draws through.
ui::RenderRecording	A Renderer that keeps every call, with its full arguments, so it can be replayed into any other Renderer later, any number of times: a resolution-independent snapshot of an element.
ui::SpellChecker	The spell-checking service a text control asks for misspellings, suggestions and autocorrections.
ui::SvgImage	An SVG document as image content: the markup, kept as text, plus the natural size read from its root element.
ui::TextAnalyzer	Unicode text segmentation and case mapping over UTF-8: where a caret may stop, what counts as a word character, and how CharacterCasing changes typed text.
ui::TextLayout	Paragraphs of differently styled runs broken into lines, with the geometry selection needs: the engine behind TextControl inlines, RichText and a multi-line TextBox.
ui::TextMeasurer	Measures text.
ui::TransformScope	Pushes a transform when it is made and pops it when it goes out of scope.

Structs¶

Page
ui::AcrylicBrush	An in-app acrylic material: what is behind the shape, over an opaque fallback, blurred (a Gaussian of standard deviation 30), then a `Luminosity` blend with effective_luminosity() and a `Color` blend with effective_tint().
ui::AnimatedImage	An animated picture: a decoded animated GIF.
ui::ContextMenuItem	One entry of a system context menu shown through ContextMenuHost::show(): a text item or a separator.
ui::CubicBezier	A cubic Bézier easing curve.
ui::FocusRingStyle	The focus visual's parameters as plain data.
ui::GradientStop	One color stop of a gradient brush.
ui::IconGlyph	One symbol-font glyph, the way every Fluent control draws its small marks (checkmark, chevron, overflow "more"): a codepoint, a font family and a default size.
ui::ImageDecodeOptions	What Bitmap::decode()/read() should do beyond decoding.
ui::ImageDiff	Comparison result for golden-image tests, from compare().
ui::LinearGradientBrush	A linear gradient running along one GradientAxis of the painted bounds.
ui::Matrix	An affine transform in row-vector layout: `x' = xm11 + ym21 + dx`, `y' = xm12 + ym22 + dy`.
ui::NativeControlDesc	The Win32 child window a NativeControl creates: a window class name, its initial text and style bits.
ui::NativeNotification	A Win32 message a hosted window sent its parent about itself (WM_COMMAND, WM_NOTIFY, WM_CTLCOLOR* and a scroll bar's or trackbar's WM_HSCROLL/WM_VSCROLL), handed to the element that owns the window by NativeControl::handle_native_notification().
ui::PathFigure	One figure of a geometry: a start point, its segments, whether the last point joins the first and whether the inside is painted.
ui::PathSegment	One piece of a figure, starting where the previous one ended.
ui::PushClipRoundedRect	A rectangular clip with rounded corners (a card or a tile whose picture follows its rounded edge).
ui::RadialGradientBrush	A radial gradient.
ui::ShadowRecipe	The two superimposed black shadows that make up a drop shadow: an omnidirectional `ambient` and a downward-offset `directional`.
ui::SpellingError	One finding of SpellChecker::check(): a range of the checked text and what to do about it.
ui::StrokeStyle	A Shape's stroke settings with their defaults.
ui::TextColorSpan	A range of text drawn in its own color, such as a token a syntax highlighter colored.
ui::TextEffect	A multi-pass text effect carried by TextStyle::effect; the classic themes use it for the engraved disabled-button label.
ui::TextHighlight	A range drawn with its own background and/or foreground, such as a highlight or the selection.
ui::TextLayoutOptions	How TextLayout::layout() breaks and aligns lines: the paragraph-level settings a TextControl or RichText passes down.
ui::TextLayoutParagraph	Runs that flow together, with a margin around the block.
ui::TextLayoutRun	One run of same-formatted text in a TextLayout paragraph, with the formatting of any enclosing spans already folded in.
ui::TextMetrics	What a TextMeasurer reports for a run of text: its extent, where its first baseline sits and how many lines it took.
ui::TextStyle	Everything a Renderer and TextMeasurer need to know about how a run of text looks: font, size, weight, alignment inside its box, wrapping, decorations and spacing.
