Detailed Description

A QIcon that renders an SVG silhouette recoloured to a ThemeManager token, tracking light/dark and theme changes automatically.

Companion to StockIcon. StockIcon selects a pre-made, per-mode raster resource; ThemedIcon renders one SVG and tints it to a live theme colour, so a single asset follows the active theme without per-mode variants. The tint uses CompositionMode_SourceIn, which flattens the rendered shape to the resolved colour — the source SVG's own colours (even gradients) don't matter, only its alpha silhouette.

It is part of the theme system and deliberately speaks ThemeManager tokens only: there are no QColor or QPalette overloads. Use a palette token (e.g. ThemeManager::PaletteText) for monochrome glyphs that should follow the text colour, or an accent token (e.g. ThemeManager::AccentSuccess) for a functional colour.

Theme tracking needs no caller code: the backing engine resolves the token colour at paint time and keys its pixmap cache on that colour, so a theme or light/dark flip is a natural cache miss and re-renders on the next repaint.

Constructor & Destructor Documentation

ThemedIcon() [1/2]

ThemedIcon::ThemedIcon ( const QString & svg_resource_path, ThemeManager::ThemeToken token, QSize size = QSize(14, 14) )

explicit

Parameters

svg_resource_path	Qt resource path of the SVG, e.g. ":/svg_icons/x-filter-clear.svg".
token	Theme colour token the glyph is tinted to.
size	Nominal render size used when a caller requests a null size.

ThemedIcon() [2/2]

ThemedIcon::ThemedIcon ( const QString & svg_resource_path, ThemeManager::ThemeToken token, ThemeManager::ThemeToken active_token, ThemeManager::ThemeToken selected_token = ThemeManager::NoRole, QSize size = QSize(14, 14) )

explicit

Stateful variant: distinct colours per interaction mode.

token colours the resting glyph (QIcon::Normal); active_token the hovered glyph (QIcon::Active); selected_token the pressed/selected glyph (QIcon::Selected, falling back to active_token). A QToolButton requests these modes itself on hover/press, so state recolouring needs no QSS — which matters because QSS cannot recolour an SVG glyph's fill. Pass NoRole for a mode to keep the single-token behaviour (a slight emphasis of token).
