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 we will explain how HTO technology enables you to rebuild an entire PB Virtual Machine for the Web. Then, addressing the business purpose - that your Web application code can become a simple line-by-line port of the original PB app - we'll demonstrate an integrated example based on PowerBuilder's Data Explorer demo scr...

We will be customizing the API and addi... (more)

Adobe Flex 2: Advanced DataGrid

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 ... (more)
