Shortcuts no longer visible in context menus since Qt 5.10

In Qt 5.10, shortcuts are no longer shown by default in context menus. However, I'd generally prefer them to be there to make them discoverable. Several actions that are only available from context menus have shortcuts that are now completely hidden.

It seems the only way to fix this is to manually specify that the shortcut should be visible for each affected action. Setting setAttribute(Qt::AA_DontShowShortcutsInContextMenus, false) has no effect, since QAction is doing:

bool QAction::isShortcutVisibleInContextMenu() const
{
    Q_D(const QAction);
    if (d->shortcutVisibleInContextMenu == -1) {
        return !QCoreApplication::testAttribute(Qt::AA_DontShowShortcutsInContextMenus)
            && QGuiApplication::styleHints()->showShortcutsInContextMenus();
    }
    return d->shortcutVisibleInContextMenu;
}

And the style hints say they should not be visible.

Just saw this on IRC, and thought I'd share https://bugreports.qt.io/browse/QTBUG-69452 with you in case you weren't aware of it.

@mitchcurtis Ah, thanks for the reference! It didn't occur to me to look for an issue because the change in behavior was clearly intensional, but I think it is a little misguided and I hope they will reconsider, or at least provide an API for enabling the showing of shortcuts in all context menus.

Unfortunately this issue persists in Qt 5.11 and Qt 5.12 (LTS). This means for now I'm going to stick to releasing against Qt 5.9, which may be a better choice in regards to stability anyway.

Since Qt 5.13.1, shortcuts are again visible by default in context menus, except on macOS, where they are deemed too out-of-place. I'll make it so that they're always shown when the "Tiled Fusion" style is selected, which is now possible using QGuiApplication::styleHints()->setShowShortcutsInContextMenus(true).
