The following example shows how you can draw complex rectangles using the drawRoundRectComplex() method in the mx.utils.GraphicsUtil class.
Full code after the jump.

hi peter,
I could not find any example of drawing API for creating basic shapes(e.g. Rectangle) with mouse!
Or at least can you suggest any site/blog where I can learn about it or see some example.
Thanks in advance :)

rconceiver,
It has a few [major] bugs, but this may get you started:

Thanks Peter,
At least it has given me a start…
Thanks once again…:)
Hey Peter,
Thanks for giving this example of drawing rectangle using mouse….it helped me in learning drawing in my assignment….Thanks once again Peter for your great help….
