Creating interactive shapes

[vujjeni]

I am creating a simple GUI that lets the user drag a circle to make it bigger. What is the best way to start this ? I am stumped.
I tried using a click event to resize the Circle but what I really want is a user drag event. My concern is how does the Circle retains its shap when the user drags it to make it bigger ?
Thanks in advance.

Try the Mousemove or MouseDown events or some combo thereof. Since if they drag it then it will move locations, wont it?

I forgot to mention that I am drawing the Circles using the graphics method, drawEllipse(); Now, How will the mouse down or mouse move events really effect a Circle drawn in execution time ? If it were a picbox, maybe I would have had a easier time.
