Sigma Visual builder is a WYSIWYG tool for rapid Web application design and involved script programming. With this powerful builder, Web applications can be developed using only drag and drop, just like what you do in VB or Delphi. More than 35 common AJAX components, including Tabs, Dialog, TreeGrid, TimeLine, and many other Web GUI components are supported. Its rich client-side API works with any backend (such as PHP, .NET, Java, or Python) or static HTML pages. The generated application has wide cross-browser compatibility.
The ObjectBrowser Bean uses Java reflection to generate a file-explorer-like GUI automatically for any Java object or set of objects. It incorporates a number of features aimed at making the UI useable, such as special treatment of array-like members as child objects, and representation of bean getter and setter methods as properties. Scripting can be used to add in additional methods to manipulate the target object.
