I used a TIB_ControlGrid instead of the TIB_Grid. Then I used a
TIB_Text control. From version 4 it has a Canvas you can paint to.
The event you use is TIB_Text.GetDisplayText.
This is what I did:
procedure Form1.MyIB_Text.GetDisplayText(Sender: TObject; var
AString: String);
var
B:TBitmap;
iIndex: integer;
begin
B := TBitmap.create;
iIndex := strtointdef(AString, 0); //gets the index of the bitmap
ImageList.GetBitmap(iIndex, B); //get the right bitmap
MyIB_Text.canvas.draw(0,0,B); //render the image
B.Free;
AString := ''; //stops the text from being printed
A little tip - do not make TIB_Text.Autosize = True. Let's just
call the result a nice little bug for JW and co. to have some fun
figuring out.
Hope it helps,
