Hi,

change the line where you set the
text into this one and comment your flags method and it works:

return
Qt::Variant.new @stringList.at(index.row())

You have to convert your string
manually into a QVariant as it is required for data() return type.

I don't
know why flags don't work. There seems to be no method like this in the
abstract class. You may want to check with a command like this
which methods
can be found:
> smokeapi -r qtgui QListView | grep Event

Best
regards,
Robert
