When clicking a Thumbnail, then the Thumbnail gets selected. So far, so good.

However, when clicking on the white space OUTSIDE a Thumbnail, then always the thumbnail NEXT to the mouse pointer gets selected:



This behavior is undesirable, as I need to DESELECT all thumbnails when I click on a white space:

procedure TformMain.ImageEnMView1MouseDown(Sender: TObject; Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
begin
  if Button = mbLeft then
  begin
    var ThisImageIdx := ImageEnMView1.ImageAtPos(X, Y);
    if ThisImageIdx = -1 then 
    begin
      ImageEnMView1.Deselect;
    end;
  end;
end;


So how can I avoid selecting a near thumbnail when clicking on the white space?

Hi Peter

Please enable CheckThumbBoundsOnSelect:

Also, ImageAtPos has a CheckBounds parameter:
