Featured is new support for development on Linux. Windows already had been supported.Based on Instantiations’s WindowBuilderPro Eclipse-based tool, GWT Designer allows developers to build rich Internet applications using Eclipse, Java and GWT without negotiating through the complexities of AJAX coding, the company said. A WYSIWYG construction environment enables dragging and dropping of composites, layouts and controls as well as cutting and pasting of code inside a text editor. Other new features include * Backing for GWT releases 1.2 and 1.3. * Visual inheritance, for reusing code and visual designs and extracting super-classes for reuse. Code quality is improved. * The ability to ensure valid GWT Java code, in which code is checked for allowed GWT classes and methods. An on-the-fly code audit is performed. GWT Designer 1.5 is available now for an annual subscription of $39 per year. Current subscribers can upgrade at no cost. A two-week trial copy is available here. Technology Industry
