XGui is a multiplatform, multilanguage native widget set. This means you can write your code once in your favorite language (C, C++, or Python) and then compile it to run on Linux or Windows with the native look of the OS. XGui is developed keeping in mind the MVC pattern. Lists and Trees are just views of a model. Even styles which define how to show the model in every different view are separated. GUIs, models, and styles can be saved and loaded from XML files.
QDrupal is a module that integrates the Qcodo PHP Framework with Drupal. The QDrupal module simply provides the integration code and requires the user to create their own QForm pages for use within the Drupal framework and page structure. Most Qcodo features are available, including code generation and access to QForms. All Drupal features are available, such as user management and CMS features.
