Hello,

with the component ThumbControl,

when I click on a thumbnail, I want to load another image (test.jpg) INSTEAD of the image I've clicked on.
For example if I click on the 3rd image of the 5th row, I want test.jpg to appear in that exact thumb.

I can get the exact thumb with:
Code: Pascal  [Select][+][-]
  1. procedure TForm1.ThumbControl1SelectItem(Sender: TObject; Item: TThreadedImage);
  2. begin
  3.    Label1.Caption := ExtractFileName(ThumbControl1.ImageLoaderManager.ActiveItem.URL);
  4.  
  5. if Item <> nil then
  6.   begin
  7.  ???
  8.   end;
  9. end;        
  10.  
   
But I can't figure out the code...

what I would like to create is, with mouse enter and mouse leave, a cool animation effect and load a different 2nd thumbs of all my images :)
many thanks

I can really get the name of the image and the position, but I can't reload that specific image with another one...

Code: Pascal  [Select][+][-]
  1. procedure TForm1.ThumbControl1MouseMove(Sender: TObject; Shift: TShiftState; X,
  2.   Y: Integer);
  3. var itm:TThreadedImage;
  4. begin
  5.  itm:=ThumbControl1.ItemFromPoint(Point(x,y));
  6.  
  7. if assigned(itm) then begin Label1.Caption:=itm.URL; Screen.Cursor := crHandPoint; end else
  8.  begin Label1.Caption:=''; Screen.Cursor := crDefault; end;
  9. end;    
  10.

Which ThumbControl are you talking about? Lazarus does not contain such a control by default, but there are several of them out there in the internet.

JvThumbView

If I understand correctly, you want to have two images per thumbnail, the first one displayed normally, and the second one displayed when the mouse is over it. I do not think that this is possible with theo's (or any other) thumb viewer. But maybe you should post this question also in the German forum where theo can be found more frequently.

yes, I don't think it's possible directly like this, this is why I simply want to load another image instead of one thumb. I'll try the German forums
