 BottomText when appending Bitmap to TImageEnMView?		  New Topic  Reply to Topic

In a TImageEnMView I add images with:

ImageEnMView1.AppendImage(ABitmap);


I need to add a different BottomText to each image. This BottomText is available only when using AppendImage. It is NOT available in the TImageEnMView.OnGetText event-handler.

So, is there a way to add BottomText when adding the images with ImageEnMView1.AppendImage(ABitmap)?

Reading the documentation, unfortunately there is no such an overload:

ImageEnMView1.AppendImage(ABitmap, ABottomText);

I have solved the problem by adding the Bottom Text to a StringList when appending the Bitmaps and then adding the Bottom Text from that StringList in the OnGetText event-handler:

procedure TformCustomClipartsListsManager.ImageEnMViewSVGCollectionGetText(Sender: TObject; Index: Integer; Position: TIEMTextPos; var Text: WideString);
begin
  if Position = iemtpInfo then
    Text := SLBottomText[Index];
end;


But this adds unnecessary complexity to the implementation and thus is error-prone. So I suggest you implement this additional overload:

function TImageEnMView.AppendImage(Bitmap : TBitmap; ATopText, AInfoText, ABottomText: string): integer;

Hi Peter

You can use:

idx := ImageEnMView1.AppendImage( 'D:\Butterfly.jpg' );
ImageEnMView1.ImageTopText[idx]    := 'Top text';
ImageEnMView1.ImageInfoText[idx]   := 'Info text';
ImageEnMView1.ImageBottomText[idx] := 'Bottom text';


Also, for bottom text you should use iemtpBottom in the OnGetText event.
