Ralf,
To your question about making a rich combo-box, I've created a filthy-rich combo box using a qx.ui.popup.Popup that contains a table instead of a list, allowing the selection of a table entry in the popup object. It wasn't really that difficult to build the popup object with the table for this purpose, although I use the textfield to drive a backend search that populates the table entries. You may be interested in more typical combo-box functionality, which is already provided by the qx.ui.form.ComboBox class in the framework.
So, in answer to your question, it's easy to build rich widget functionality by combining existing classes. I just had to create a listener for the qx.ui.form.TextField widget to display the popup and an appropriate selection listener for my popup contents (list, table, etc.) to drive the behavior I needed from a user selection in the popup. If you're interested in standard ComboBox functionality, just use the qx.ui.form.ComboBox class, otherwise you can build interesting popups in Qooxdoo quite easily like I did.
I'm really just a beginner myself, and this proved to be easy once I understood the Qooxdoo widget usage and listener functionality. This is why the ComboBoxEx (textfield with a popup table) in 0.7.x was never ported to 0.8 - because it's so easy to build within your app code, you don't really need a widget in the framework.

If by a combo-box you mean both a list and an editable text field, not really, we just display the single-selection list containing a choice of options for the user. The popup is set to fade out after three seconds if the user doesn't enter the popup with the mouse. This works ok enough for now. I have improvements in mind but I don't know when I'll get around to it.
