drop down list in inspector

[damichab]

Hi,

Have a problem, have been thrown into the deep end with borland C++ builder. The boss wants an AnsiString drop down list to appear in the object inspector and I do not know how to achieve this.

Have worked out how to put a single AnsiString into it and this is what I have so far for the drop down list...

within .h...
__published:
__property TStringList Words[int Index] = {read=GetWords, write=SetWords};

private:
TStringList* Words;
AnsiString __fastcall GetWord(int Index)
void __fastcall SetIndexName(int Index, AnsiString str)

Within cpp...

AnsiString __fastcall GetWord(int Index)
{
return FWord->String[Index];
}

void __fastcall SetIndexName(int Index, AnsiString str)
{
FWord->String[Index] = str;
}

I would have thought that something along these lines should produce the drop down list box, but evidently I have missed something. All I get is an out of bounds type error.

Any link to a suitable sample or advice appreciated.

Thanks in advance,

David B.

If you want a drop down list, I think that you need first the list which you want to drop down.

I did a Gradient component which you can choose if you want the gradient Vertical or Horizontal.

like this:
enum TDirection { dHorizontal, dVertical};

__published:
__property TDirection Direction = { read=FDirection, write=SetDirection, default=dVertical};

And BCB automatically creates a DropDownList which contains both values (dVertical and dHorizontal)
