Cairo is not a scenegraph so you have to draw everything on expose. There are cairo based scenegraphs available if that is what you are looking for. >>I dont wish to explicitly draw the three rectangles by specifying the co-ordinates.Is their a better way to >>do it? I don't quite understand how you can draw anything without specifying where. Even if indirectly by cairo_translate. ~Gerdus <div class="gmail_quote">On Sat, Dec 20, 2008 at 6:48 AM, abhidhnya sonawane <<a href="mailto:abhidhnya.sonawane@gmail.com">abhidhnya.sonawane@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hi, I wish to draw three rectangles on the drawing area. But after  finishing drawing  one ,I draw the next. Also I wish to add the scaling effect to it.Like the first rectangle is initially small.I enlarge it to a particular size and then draw the next one. I have accomplished this , but because I call queue_redraw in my timer function the previously drawn rectangle vanishes and then the second one is drawn. I dont wish to explicitly draw the three rectangles by specifying the co-ordinates.Is their a better way to do it?
