Description

when trying to use qml plugins in a statically linked application, i figured that i need to registerTypes/initializeEngine explicitly on osx when not using namespaces.

as a workaround, i currently have the following code in my application:

#if defined(QT_STATIC) && !defined(Q_OS_MAC) && !defined(QT_NAMESPACE)
    qobject_cast<QQmlExtensionPlugin*>(qt_static_plugin_QtQuick2Plugin().instance())       ->registerTypes("QtQuick");
    qobject_cast<QQmlExtensionPlugin*>(qt_static_plugin_QtQuickControlsPlugin().instance())->registerTypes("QtQuick.Controls");
    qobject_cast<QQmlExtensionPlugin*>(qt_static_plugin_QtQuickControlsPlugin().instance())->registerTypes("QtQuick.Controls.Private");
    qobject_cast<QQmlExtensionPlugin*>(qt_static_plugin_QtQuickControlsPlugin().instance())->registerTypes("QtQuick.Controls.Styles");
    qobject_cast<QQmlExtensionPlugin*>(qt_static_plugin_QtQuickLayoutsPlugin().instance()) ->registerTypes("QtQuick.Layouts");

[...]

    qobject_cast<QQmlExtensionPlugin*>(qt_static_plugin_QtQuick2Plugin().instance())       ->initializeEngine(engine, "QtQuick");
    qobject_cast<QQmlExtensionPlugin*>(qt_static_plugin_QtQuickControlsPlugin().instance())->initializeEngine(engine, "QtQuick.Controls");
    qobject_cast<QQmlExtensionPlugin*>(qt_static_plugin_QtQuickLayoutsPlugin().instance()) ->initializeEngine(engine, "QtQuick.Layouts");

#endif

would be great if it could be fixed so that Q_IMPORT_PLUGIN is enough on all platforms/namespace configurations
