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 NetBeans for free.
Why even consider Flex for developing Rich Internet Applications (RIA)?
First, we'll give the short answer. Just look at the code in Listing 1. This
code compiles and runs in the Flash player and produces the output shown in
Figure 1. Yes, it's a tree control with several no... (more)
In this excerpt from our book, Rich Internet Applications, we'll cover how to
set up large applications intended for Web or, more broadly speaking,
distributed deployment. As an example let's consider an enterprise
application that consists of hundreds of screens, reports, forms, and
dashboards. Accordingly, about a dozen engineers specializing in GUIs,
frameworks, data layers, and business domains are working on this application
in parallel.
Every application "run" in Flex Builder as well as the invocation of the
application's MXML file processed by the Web-tier Flex compiler r... (more)
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)
In Part 1 (CFDJ, Vol. 8, issue 10) we introduced the destination-aware grid,
formatters, and renderers. In this article we are continuing our discussion
about datagrid renderers and...
RadioButtonGroupBox as Drop-In Renderer
We can apply similar techniques to RadioButton controls. The following code
snippet suggests how the group of RadioButton controls can be used as a
drop-in item renderer (and editor). Instead of an onValue/offValue pair, we
are introducing an array of options (we could have gone further and upgraded
to , which is similar to the Bu... (more)
I’d like to use this opportunity and invite Flex developers living in
Europe to attend our Advanced Flex Master Class in Brussels, Belgium on March
1 and 2, 2010.
This question we get on almost every new client project: “We’re
struggling with handling of null values for numeric data types in Flex/Java
projects.
Every time there’s an update, we end up replacing the original nulls with
zeros when the user didn’t actually change that value.
Have you guys come up with a silver bullet for handling numeric nulls?”
Consider a Java method with a Double parameter. You pass uninitialized ... (more)
