ToolbarIconSet.h File Reference

Toolbar tool icons, rendered from embedded two-tone SVG art through Donner. Black cores and white halos are preserved so the toolbar and OS cursors use one contrast system on every surface (see donner/editor/art/STYLE.md). More...

Include dependency graph for ToolbarIconSet.h:

Classes
struct	donner::editor::ToolbarIconTexture
	An uploaded icon texture plus the valid payload UV range (icon bitmaps may be padded to a texture-friendly size). More...

Namespaces
namespace	donner
	Top-level Donner namespace, which is split into different sub-namespaces such as donner::svg and donner::css.

Typedefs
using	donner::editor::ToolbarIconTextureProvider
	Uploads a Donner-rendered icon mask bitmap to an ImGui texture. Mirrors the IconTextureProvider callbacks the layers/inspector panels already pass down, so the shell reuses one texture-upload path.

Enumerations
enum class	donner::editor::ToolbarIcon : std::uint8_t {   Select ,   Pen ,   Text }
	A tool that has a toolbar icon. Mirrors the palette buttons in display order; kept standalone so the registry-coverage test can iterate it without a live ImGui context. More...

Functions
std::span< const unsigned char >	donner::editor::ToolbarIconSvg (ToolbarIcon icon)
	Embedded SVG source bytes for icon.
std::uint64_t	donner::editor::ToolbarIconTextureKey (ToolbarIcon icon)
	Stable texture-cache key for icon.
const std::optional< svg::RendererBitmap > &	donner::editor::CachedToolbarIconBitmap (ToolbarIcon icon)
	The Donner-rendered two-tone bitmap for icon, rendered once and cached for the process lifetime. std::nullopt if parsing/rendering failed.
std::span< const EmbeddedSvgIconRequest >	donner::editor::ToolbarIconPrewarmRequests ()
	Every toolbar icon rasterization, for the shell's startup prewarm batch. The palette is on screen from the first frame, so all of these are paid during boot whether or not they are prewarmed.
void	donner::editor::DrawToolbarIcon (ToolbarIcon icon, const ImVec2 &min, const ImVec2 &max, ImU32 tintColor, const ToolbarIconTextureProvider &provider)
	Draw icon centered within the button rect [min, max], tinted with tintColor. No-op when provider is null or the icon can't be uploaded (e.g. headless tests with no GL context), leaving the button blank rather than crashing.

Variables
constexpr std::array< ToolbarIcon, 3 >	donner::editor::kToolbarIcons
	Every toolbar icon, in palette order. The single source of truth for the icon registry and its coverage test.

Detailed Description

Toolbar tool icons, rendered from embedded two-tone SVG art through Donner. Black cores and white halos are preserved so the toolbar and OS cursors use one contrast system on every surface (see donner/editor/art/STYLE.md).

Typedef Documentation

ToolbarIconTextureProvider

using donner::editor::ToolbarIconTextureProvider

Initial value:

 
    std::function<ToolbarIconTexture(std::uint64_t stableId, const svg::RendererBitmap& bitmap)>

Uploads a Donner-rendered icon mask bitmap to an ImGui texture. Mirrors the IconTextureProvider callbacks the layers/inspector panels already pass down, so the shell reuses one texture-upload path.

Enumeration Type Documentation

ToolbarIcon

enum class donner::editor::ToolbarIcon : std::uint8_t

strong

A tool that has a toolbar icon. Mirrors the palette buttons in display order; kept standalone so the registry-coverage test can iterate it without a live ImGui context.

Enumerator
Select	Selection / arrow tool.
Pen	Pen (path) tool.
Text	Type / text tool.

Variable Documentation

kToolbarIcons

std::array<ToolbarIcon, 3> donner::editor::kToolbarIcons

inlineconstexpr

Initial value:

= {
    ToolbarIcon::Select,
    ToolbarIcon::Pen,
    ToolbarIcon::Text,
}

Every toolbar icon, in palette order. The single source of truth for the icon registry and its coverage test.
