Where will you specify C++ code, e.g. methods like "draw"? In QT, XML is converted to real C++ code that you can subclass and add behaviour there. In Mozilla, XUL is scriptable via JavaScript.
What can be done here?
// create a xml archive, deserialize w widget w = create_widget("description.xml");
[...]
button b = cast<button>( w->find_by_name("my_button") ); b->clicked_signal = my_callback;
Aha, and that requires that all functionality is implemented as standalone functions. This might be okay for clicking buttons, but for custom widgets (e.g. text editor), I'd still prefer subclassing. Oh, so we need XML to be able to store not only some predefined widgets, but also custom widgets. And to edit those custom widgets, we'd need GUI editor which can understand plugning. We're getting close to duplicating QDesigner ;-)
// do nothing, a Python function is automatically attached to clicked_signal // Python should be able to see the widget as an object // Nontrivial
This sounds like a best solution. At least for dialogs, Python's performance should not matter. - Volodya
