Action Listeners : How do they work?

[Paritosh Ranjan]

Hi,

I wanted to add a preview data support.

However,I saw that there is an built in support in the form of
PreviewTransformedDataActionListener.

Can someone explain how it (Action Listeners) works( read it
architecture, usage :)).

Thanks and Regards,
Paritosh

Hi Paritosh,

ActionListeners are the main sort of "action" object in Swing. If you
want your button to have an action, you'll do something like this:

JButton button = new JButton("click me");
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println("hello");
}
});

Actually I wanted some information about How PreviewTransformedDataActionListener works. I will try to make the question more clear this time.

What all do I have to do to create a Preview Button which shows some data in a different window?
Looking at the classes shows, there is already something of this sort implemented.

I figured out the button being added in TransformerJobBuilderPanel. However, mine is an Analyzer.
Can you please explain a little bit about Jobs also.

Thanks and Regards,
Paritosh

Well the PreviewTransformedDataActionListener is actually quite complicated so I think it's maybe not the place to start. In short it simulates a complete job where rows are being transformed and if you just want to preview some data then this is not needed.

Rather I would refer you to DataSetWindow, which is a window class used to present a dataset. There are a few different constructor options for DataSetWindow - either you can base it on a Query, a TableModel and you're also invited to consider if we need to supply other constructors.

I will get back to you about jobs ... Actually I am going to write a little bit about it in the developer FAQ and post the link in a few hours.

It works great. Thanks.

Hi everyone,

I'm using these questions as an opportunity to build up a site with questions and answers and some explanations about the architecture of DataCleaner and AnalyzerBeans. Please check the website (it's work in progress) here:

http://analyzerbeans.eobjects.org/

and for paritosh's particular question regarding jobs:

http://analyzerbeans.eobjects.org/architecture.html

Let me know if you have more questions or topics that we need to provide on the site.

Best,
Kasper
