Is it possible to create a similar editable selection list with the help of simple Clearwin+-elements?
I've experimented with %lv and %ob.
Maybe there are already appropriate examples. I would be grateful for any help.
Editable Selection List
ClearWin+ does not have a 'Properties' dialog like this. Perhaps the nearest thing is a parameter box %pb. I think that users would tend to use separate edit boxes, list boxes and combo-boxes. If you have lots of them then, with the latest ClearWin+, you can form a scrolling dialog box. See item 355 in cwplus.enh.
You might also look at tabbed property sheets with %ps, although this will give a different look and feel to the application.
There is no limit to what visual effects you can achieve in a %gr region, but at great cost in time and effort.
