The status bar that appears at the bottom of a NetBeans Platform application can be extended with your own components. When I recently wanted to do this, I searched the Internet for good resources on this topic. And so I found this blog entry by Emilian Bold<\/a>. It is very useful indeed, but it dates back to before the introduction of the @ServiceProvider<\/a> annotation. And so I decided to write this article with more up do date information.<\/p>\n

Just as Emilian describes, the first step is to create a class that implements StatusLineElementProvider<\/a>.<\/p>\n

[java]import java.awt.Component;
\nimport javax.swing.JLabel;
\nimport org.openide.awt.StatusLineElementProvider;<\/p>\n

public class NewStatusLineElement implements StatusLineElementProvider
\n{
\n @Override
\n public Component getStatusLineElement()
\n {
\n return new JLabel(“Shalom”);
\n }
\n}[\/java]<\/p>\n

This requires a module dependency on the UI Utilities API module.<\/p>\n

The difference is that instead of adding an entry to a META-INF\/services file, we add the @ServiceProvider annotation to the class:<\/p>\n

[java]import java.awt.Component;
\nimport javax.swing.JLabel;
\nimport org.openide.awt.StatusLineElementProvider;
\nimport org.openide.util.lookup.ServiceProvider;<\/p>\n

@ServiceProvider(service = StatusLineElementProvider.class, position = 100)
\npublic class NewStatusLineElement implements StatusLineElementProvider
\n{
\n @Override
\n public Component getStatusLineElement()
\n {
\n return new JLabel(“Shalom”);
\n }
\n}[\/java]<\/p>\n

This requires a dependency on the Lookup API module.<\/p>\n

One more interesting point. I wanted to add a separator between two of my items, but it just would not appear. And then I realised it might need to have a size specified. So here is the getStatusLineElement() method that successfully adds a separator:<\/p>\n

[java]@Override
\npublic Component getStatusLineElement()
\n{
\n JSeparator s = new JSeparator(SwingConstants.VERTICAL);
\n s.setPreferredSize(new Dimension(5, 16));
\n return s;
\n}[\/java]<\/p>\n","protected":false},"excerpt":{"rendered":"
