Subject: Re: I have place 3 imagescrollbox object, how to use the same functions?
In reply to: Raymond Cheng 's message, "I have place 3 imagescrollbox object, how to use the same functions?" on 12:39:35 07/27/00 Thu

Hi Raymond,

I'm not sure what you mean. Are you trying to share the code so that you may reuse it with another ImageScrollBox. If that is the case, you can create a procedure and pass as parameters the necessary objects. For example,

procedure Rotate90( const UndoGraphic : TDibGraphic;
const ImageScrollBox : TImageScrollBox );
the procedure is really the same but replace
ImageScrollBox1 by ImageScrollBox
FUndographic by UnGraphic

Best regards,
