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.
