You seriously need to read the documentation on the model/view framework
in Qt. http://doc.trolltech.com/4.3/model-view-programming.html

In short: You can retrieve the model indexes from the selection, with
that index you can ask the model itself for the data of that index via
the model's data() function. That function takes an index, a role
(usually you want Qt.DisplayRole here, but it may also need a custom
role, that depends on the implementation of the model). This will return
a QVariant carrying the data, you just need to get out the actual data
(string, integer, list and so on) and can then populate the custom
widget.
