Java drawing editor applet

I'm looking for a Java Applet which allows the user to draw rectangles, resize them, move them etc, similar to svg-edit http://code.google.com/p/svg-edit/

It will be for academic non 开发者_如何学Ccommercial use. Can anyone point me to a good, open source, Java drawing editor applet?

The best applet I know of, with source available, is draw4free.

• Applet
• Website
• Source code

If you are looking for inspiration, there's a few listed here but most don't have the source available.

If you are less fussed about it being an applet, there's a list of those too (most with source) and you could also check out:

• jHotDraw which is based on a formerly commercial project
• JDraw and Pixelitor, although they are about editing bitmaps rather than shapes
• Sketcher (discontinued)
• The imaginatively titled "draw" which looks like a very simple option

There's loads of examples out there. I got some of this by searching Sourceforge/Google.

GraphPanel is a java-web-start application, rather than an applet.

Addendum: JGraph is a more full-featured object drawing environment.

You can use above open source project built using Java Swing and customize it based on your requirements.
