Miquel! Class Rectangles_AllMovements includes Draw() method. In the shown example it is organized in the simplest way and fills rectangle with the selected color. You can change this method to whatever you need; moving and resizing work independently of drawing. Regards, Sergey Andreyev PS Sorry for delay. I didn’t look inside the project for some time. You could send you r question directly on the E-mail address which is mentioned everywhere (for example, in the About form).
