The UI Helpers repository contains non-widget based ui classes that are useful for those who intend to develop applications using Qt 5/QtQuick 2 but do not want to depend on QtWidgets – mainly desktop applications. Examples of classes are QUndoCommand, QAction, QFileSystemModel, etc. http://qt-project.org/wiki/Qt5UiHelpers Suggestions and contributions are welcome – contact us on development@qt-project.org
