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.
  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).

Review Change Stack

📝 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.

…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.

1-1: 🎯 Functional Correctness | 🔵 Trivial | 🏗️ Heavy lift

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)
