How do i add an icon to the context menu?

NOTE: This is not recommended for NB RCP (it will break HMI standards on Mac OS X for example), but is still possible.

Steps:

  • let your action implement Presenter.Popup and return a JMenuItem instance for the current action (see [1], [2])
  • set the icon via putValue(javax.swing.Action.SMALL_ICON, ...)
  • set the icon via putValue("iconBase", ...) to make it work properly in the toolbar. Otherwise you will get a fixed size icon.
@ActionID(
        category = "Build",
        id = "sample.contextmenu.HelloIconAction")
@ActionReferences({
    @ActionReference(path = "Menu/File", position = 0),
    @ActionReference(path = "Loaders/Languages/Actions", position = 0),
    @ActionReference(path="Projects/Actions")
})
@ActionRegistration(
        displayName = "#CTL_HelloIconAction")

@Messages("CTL_HelloIconAction=Hello Icon Action")
public final class HelloIconAction extends AbstractAction implements Presenter.Popup {

    @StaticResource
    private static final String ICON = "sample/contextmenu/sample.gif";
    private static final long serialVersionUID = 1L;
    private final Lookup context;

    public HelloIconAction() {
        context = Utilities.actionsGlobalContext();
        putValue(SMALL_ICON, ImageUtilities.loadImageIcon(ICON, false));
        putValue(NAME, Bundle.CTL_HelloIconAction());
        putValue("iconBase", "sample/contextmenu/sample.gif");
    }

    @Override
    public boolean isEnabled() {
        return null != context.lookup(Project.class);
    }

    @Override
    public void actionPerformed(ActionEvent ev) {
        JOptionPane.showMessageDialog(null, "Hello colorful project.\n" + context.lookup(Project.class).toString());
    }

    @Override
    public JMenuItem getPopupPresenter() {
        return new JMenuItem(this);
    }
}
