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.
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.
