Resolves: #34605
Depends on: musescore/muse_framework#238

Summary of Changes

Fixes keyboard shortcuts (⌘A, ⌘C, ⌘V, ⌘X, ⌘Z, ⇧⌘Z) failing with error beeps or executing background score actions when typing in native macOS Save/Export/Open dialogs (NSSavePanel / NSOpenPanel).

  1. 100% Platform-Agnostic AppMenuModel:

    • AppMenuModel::makeEditMenu() contains pure cross-platform item declarations with zero macOS-specific headers or #ifdef branches.
    • AppMenuModel::load() notifies platform hooks via appMenuModelHook()->onAppMenuInited(items).
  2. Dynamic Menu Introspection in MacOSAppMenuModelHook:

    • Locates menu-edit dynamically to determine the top-level Edit menu index in [NSApp mainMenu].
    • Inspects editMenu->subitems() against command constants (UNDO_COMMAND, REDO_COMMAND, CUT_COMMAND, COPY_COMMAND, PASTE_COMMAND, SELECT_ALL_COMMAND) and passes the linear indices to muse::MacOSInteractiveHelper.
    • Sets NSMenuEnableActionImages = NO in NSUserDefaults on startup alongside existing dictation and character palette suppression to keep menus icon-free on macOS Tahoe / Sequoia.
  3. Submodule Update:

  • I signed the CLA as yuan3y
  • The title of the PR describes the problem it addresses.
  • Each commit's message describes its purpose and effects, and references the issue it resolves. If changes are extensive, there is a sequence of easily reviewable commits.
  • The code in the PR follows the coding rules.
  • I understand all aspects of the code I'm contributing and I'm able to explain it if requested.
  • The code compiles and runs on my machine, preferably after each commit individually. I have manually tested and verified that my changes fulfil their intended purpose.
  • No prior attempts to resolve this problem exist, or if they do, I listed them in my PR description and described how I avoided repeating past mistakes.
  • There are no unnecessary changes.
  • I created a unit test or vtest to verify the changes I made (if applicable).

📝 Walkthrough

Walkthrough

The application menu initialization hook now receives the constructed MenuItemList. The macOS implementation locates the Edit menu, maps supported edit commands, and registers their positions with MacOSInteractiveHelper. The stub implementation accepts and ignores the list. The muse submodule reference points to a newer commit.

Add one end-to-end macOS shortcut test.

The upstream tests verify menu-item transformation and restoration, but they do not dispatch Cmd-A, Cmd-C, Cmd-V, Cmd-X, Cmd-Z, or Shift-Cmd-Z through a real native dialog text field. Add a macOS integration test that focuses the filename field in an NSSavePanel or NSOpenPanel, dispatches these shortcuts, and verifies the text and undo behavior. This will cover first-responder routing and scope lifetime. (raw.githubusercontent.com)

Giving my preemptive design approval on the behavioral change here! One small thing I noticed in the UI though. The edit menu has no icons normally, but some macOS icons (added in Tahoe) are showing up in the menu when it's opened while the save dialog is open. Would be great if we could hide those, since for now we aren't using the macOS menu icons anywhere else.

Regular edit menu:

…der during native macOS dialogs

- Pass top-level application menu items to IAppMenuModelHook::onAppMenuInited.
- Dynamically derive top-level Edit menu index (accounting for macOS Application menu offset) and linear item structure from command constants in MacOSAppMenuModelHook.
- Update muse submodule to incorporate NativeDialogScope First Responder delegation.

Hi @avvvvve , sharp eyes, good catch!

I've updated the implementation to suppress those automatic macOS action icons during the native dialog scope (via NSMenuEnableActionImages and clearing AppKit's internal action images in NativeDialogScope).
The Edit menu now remains clean and icon-free throughout the dialog lifecycle, fully consistent with the rest of MuseScore Studio's menus.

Please see how it looks like now that action icons now hidden during native dialog scope.
