  • Resize form objects in Java

    - by PeerFull
    I have a Java applet, which is a form that draw shapes into it (Rect, Oval, Line). Each shape is represented by 2 points and can draw itself to the form. When the JApplet form resizes, I need to resize the shapes also while keeping the aspect ratio. I didn't find an high quality solution for doing this that solves this problem. Tried to write a solution from this, but it came up as lousy when tested, Can someone publish an example code for doing that please?
