In any GUI tool, one of the most popular components is the one that shows data in a table format like JTable in Java or Datawindow in PowerBuilder. The Adobe Flex 2 version of such a component is called DataGrid. In any UI framework, the robustness of such a component depends on formatting and validating utilities as well as a whole suite of data input controls: CheckBoxes, ComboBoxes, RadioButtons, all sorts of Inputs, Masks, and so on. Using theatrical terminology, the role of the king is played by his entourage. Practically speaking, touching up the DataGrid is touching up a large portion of the Flex framework. We'll start by upgrading the standard DataGrid to a "destination-aware" control capable of populating itself. Next, we'll look at the task of formatting DataGrid columns and that would naturally lead us to a hidden treasury of the Flex DataGrid - the Data... (more)

Meet AJAX: Intelligent Web Applications with AJAX

Browser-based applications are widely used and we like the fact that we can access them from anywhere. But from the users' perspective, the productivity level of Web applications still doesn't approximate the productivity of desktop programs. The good news is the gap is closing: the accumulated potential of multiple technologies has boosted a whole new breed of HTML-based apps that are as powerful as the desktop ones. Meet AJAX. What Is AJAX? The name stands for Asynchronous JavaScript + XMLHTTPRequest and means you can establish socket communication between browser-based JavaScri... (more)

Developing Intelligent Web Applications With AJAX (Part 2)

The publicity that AJAX grabbed over the last half a year is based on closing the gap between the Web applications and the desktop applications, combining the "reach" and "rich." At the same time, the gap between the technological level of AJAX and what corporate developers expect in their modern arsenal is really astonishing. After all, AJAX is neither a tool nor a platform. There is no AJAX standards committee or community process in place. While software vendors are crafting proprietary development platforms on top of AJAX (which pretty much means "from scratch"), early adopte... (more)

Deploy Your PowerBuilder Applications On The Web

The ability to deploy applications on the Internet or intranet has become essential for application development, especially when developing new applications with Internet/J2EE-compatible tools. For PB developers this meant that instead of a single high-level integrated environment, they had to use low-level tools and a multitude of languages and technologies, and write more code while delivering less functionality. The problem became even more apparent when they needed to transfer existing applications to the Web. As we'll see in this article, this is no longer the case. Deploymen... (more)

Rich Internet Applications with Adobe Flex 2 and Java

A typical Java developer knows that when you need to develop a GUI for a Java application, Swing is the tool. Eclipse SWT also has a number of followers, but the majority of people use Java Swing. For the past 10 years, it was a given that Swing development wouldn't be easy; you have to master working with the event-dispatch thread, GridBaglayout, and the like. Recently, the NetBeans team created a nice GUI designer called Matisse, which was also ported to MyEclipse. Prior to Matisse, JBuilder had the best Swing designer, but it was too expensive. Now a good designer comes with N... (more)
