I wouldn't do it in draw(), because draw() can be called at any time when there's a need to (re)draw, such as resizing and show()ing after hide() and so on... I recommend to start the timer once the image is loaded and to call repeat_timeout in the timer callback. The only other thing(s) the timer callback has to do would be to increment (and wrap to 0) the image index and call redraw(). There would also be a need for a destructor to remove the timer. The draw() method would have to draw the correct image by index. Sounds all fairly easy if you know how to load and display one particular picture of the animated gif image set.
