Implement option for oversized noteheads (#34797) - #34895
MichaelGerecke wants to merge 1 commit into
Conversation
📝 WalkthroughWalkthroughThe change adds five oversized notehead symbols and exposes them through the API. Engraving fonts can clone themselves, track oversized-notehead state, and resolve standard noteheads to oversized variants. A new score style controls this behavior. Score layout caches the selected font and applies the style. The EditStyle dialog includes a “Prefer oversized noteheads” checkbox. Priority: ⬇️ Low Merge Risk: 🟡 Moderate · up to The change can alter existing Bravura rendering, misplace stems through incorrect anchor assignment, and remap numeric style IDs.

Keep the selected font default unless the score overrides it.
Score::setEngravingFont() only replaces m_engravingFont. doLayoutRange() then clones the font and unconditionally applies MStyle::value(Sid::oversizedNoteheads). An unset style value falls back to the global StyleDef value false, which overwrites Bravura’s font default true. A style-boundary default alone cannot preserve per-font behavior when the font changes. Retain the cloned font default and apply the style value only when explicitly set.

Load glyph metadata without oversized notehead resolution.
clone() copies m_oversizedNoteheads and reloads metadata while that flag is enabled. loadGlyphsWithAnchors() then maps noteheadWhole to the valid noteheadWholeOversized symbol, although Bravura defines no anchors for the oversized glyph. The clone therefore assigns base-notehead anchors to the oversized symbol. Use direct m_symbols indexing while loading metadata, or disable oversized resolution during the load.

Preserve existing Sid ordinals.
Sid uses implicit numeric values and is exposed through Q_ENUM_NS(Sid). Inserting oversizedNoteheads shifts every later ordinal. Name-based plugin access and XML persistence remain safe, but consumers that use raw Sid or QMetaEnum values can resolve old ordinals to different styles. Append the member before STYLES with its matching styleValues entry, or assign explicit stable values while preserving array indexing.

I guess we can drop "MuseScore will use" and replace it with "Use"

Yes, that was phrased a bit too defensively. In general, I'd suggest only making the checkbox 'enableable' if the font actually supports oversized variants. That way, one could also get rid of that "Prefer ...".
I'll try to investigate this next week, but I'm not sure yet how to check a font for feature compatibility. As far as I know, Leland, Emmentaler, Finale Maestro & Broadway, and MuseJazz don't support oversized variants. Gootville and Petaluma do have values in their metadata, but currently (almost) nothing changes for them in my implementation – for example either because my code is buggy or because no alternative glyphs are present despite the metadata. If it's the latter, I'm out of ideas concerning font compatibility checks.

Overview
This PR implements a new global style option (
Sid::oversizedNoteheads) to support oversized noteheads. More specifically, it allows users to opt out, as external fonts are currently loaded with oversized noteheads by default. This ensures better usability across a wider range of fonts. To maintain backward compatibility, the option is disabled by default for all fonts except Bravura, which has it enabled by default when loading font defaults.Changes Made
SymIdenums and string mappings specifically for oversized noteheads.Sid::oversizedNoteheadsstyle definition along with a corresponding checkbox in theEditStyledialog.EngravingFontto enable dynamic symbol resolution and cloning, which is necessary to isolate font instances and prevent state sharing.record.mp4
