The "Command - Control - Spacebar" should trigger the emoji input dialog. It does nothing.

Adding a MenuBar simply adds a QML menu to the window, instead of creating a native macOS menu, so macOS will not magically add the input shortcut.

Trying to use the import Qt.labs.platform 1.0 will prevent the app to start with the error:

Cannot assign object to property

The error is generated when I'm trying to assign a MenuBar to the menuBar property. Removing the import allows the app to start, but it creates a local (not native) menu bar.

Even if that would work, my app doesn't support an edit menu bar, as it sits in the tray. What it needs is a method to display the emoji input dialog.
