Problem with Droplists and new Value [message #36519]

Hi all,

In order to activate new Value, SVO_VALUE flag must be added to the main package configuration. All is working well except when you need to use DropList and want to add richtext items to the droplist with AttrText for example.

In that case, the GetIndex() function retuns -1 and Assertation message error ">=0 and <GetCount() in Vcont.h" is displayed.

A test case is enclosed. This shows that DropList::GetIndex() returns systematically -1. I am running MS Win XP and MSC9 for compilation.

So how to keep the possibility of using richtext encoding in droplist items using AttrText as before new Value was implemented? Anybody has an idea ?

Thanks in advance

AttrText cannot be used as key in droplist, because it lacks comparison operator. This would be broken without SVO_VALUE as well.

Easy solution in this case is to use integer index

dl.Add(0, AttrText("First").SetFont(Arial(12)).Bold().Ink(Red));

(and you can assign values directly then by SetData/<<=, no need to use SetIndex).

Hello Mirek,

Thank you very much for your reply. Sure it is clear that using int index in Add function solves completely the problem. Sorry for not having thought about it, I was so blind Embarassed
