eNode Secure Sandbox is an application that you can use to experiment with sophisticated Swing-based user interfaces described in a markup language.

For your convenience, the application includes a rudimentary text editor, but you should seriously consider using a professional XML tool, or at least a better text editor.

To realize objects from markup, simply load a document from your local disk by selecting Load from the Object menu. Alternatively, you may copy your content from an external text editor and paste it into the editor window of the application. In the latter case, you can realize objects by selecting Make from the Object menu.

To use your own Java™ classes with your markup data, your application must use a compatible object realizer.
