The application I'm writing will have a small group of key-value pairs associated with each object. Looking through the docs, I see widgets for displaying elementary items (e.g. TQListBox), but nothing for something like a TQMap (e.g. a TQlistBoxMap). I could use a TQTable, but that strikes me as akin to using a sledgehammer to kill flies. As a neophite c++ programmer, I know that in theory I can subclass TQListBoxItem to do this, but how to go about that, I haven't a clue. The docs say merely that ' If you need to insert customized items into a TQListBox you must inherit this class and reimplement paint(), height() and width().' Any suggestions to help get me started with this would be appreciated.

If I understand correctly, you want a two-column widget to show key-value from a map. Easiest things that come to mind are:
1) use TQTable, probably the quickest way 2) use a TQListView with two columns, also quick quick
You can ofcourse do more fancy stuff with subclassing, but I don't really see a need for this here, as long as my understanding is correct.

Ah! TQListView looks like just the ticket. I somehow overlooked that one while finding TQListBox and TQTable. Thanks for your help.
