[WIP] [macOS] Handle keyboard shortcuts using NSMenuItem
Created by: ColinKinloch
This allows keyboard shortcuts to be handled by macOS rather than by godot which correctly handles the keyboard layout "Dvorak - QWERTY ⌘".
Fixes #4386 (closed)
This solution may seem a bit hacky but reading the macOS developer docs, it's the only way I could figure see. As far as I can tell:
- there is no way to get info on the shortcut remapping done for "Dvorak - QWERTY ⌘" from the macOS API.
- there is no way to create a keyboard shortcut ("keyEquivalent") without adding it to the menu bar.
This code still has a few issues that need worked out:
- the shift modifier is incorrectly being added to shortcuts that don't have shift.
- godot shortcut handling should be disabled so that unremapped keyboard shortcuts don't get triggered.
- shortcuts cannot yet be changed or removed.
