1. The document discusses extending the Java editor by describing project and file templates, editor and file actions, code generators, and error annotations. 2. Project templates allow defining new project types and file templates allow defining new file types. 3. Editor and file actions allow adding new functionality through menu items or context menus that can perform operations on open files or projects.

3. Project Templates

4. Project Templates
@TemplateRegistration(
folder = "Project/Samples/Standard",
displayName = "#MyApp_displayName",
description = "MyAppDescription.html",
iconBase = "org/nb/alpha/deps/MyApp.png",
content = "MyAppProject.zip")
1.
public class MyAppWizardIterator implements
WizardDescriptor.InstantiatingIterator {

5. File Templates

6. File Templates
@TemplateRegistration(
folder = "Other",
content = "AbcTemplate.abc")
package org.nb.alpha.deps;
import org.netbeans.api.templates.TemplateRegistration;

7. Editor Actions

8. Editor Actions
@ActionID(
category = "Tools",
id = "org.nb.alpha.deps.SomeAction"
)
@ActionRegistration(
displayName = "#CTL_SomeAction"
)
@ActionReferences({
@ActionReference(path = "Menu/File", position = 0),
@ActionReference(path = "Editors/text/x-java/Popup", position = 400)
})
@Messages("CTL_SomeAction=Some")
public final class SomeAction implements ActionListener {
private final DataObject context;
public SomeAction(DataObject context) {
this.context = context;
}
@Override
public void actionPerformed(ActionEvent ev) {
// TODO use context
}
}

9. File Actions

10. File Actions
@ActionID(
category = "Tools",
id = "org.nb.alpha.deps.AnotherAction"
)
@ActionRegistration(
iconBase = "org/nb/alpha/deps/icon.png",
displayName = "#CTL_AnotherAction"
)
@ActionReferences({
@ActionReference(path = "Menu/File", position = 0),
@ActionReference(path = "Loaders/text/x-java/Actions", position = 0)
})
@Messages("CTL_AnotherAction=Another")
public final class AnotherAction implements ActionListener {
private final DataObject context;
public AnotherAction(DataObject context) {
this.context = context;
}
@Override
public void actionPerformed(ActionEvent ev) {
// TODO use context
}
}

11. Code Generators

12. Code Generators
public class ActionPerformedGenerator implements CodeGenerator {
JTextComponent textComp;
private ActionPerformedGenerator(Lookup context) {
textComp = context.lookup(JTextComponent.class);
}
@MimeRegistration(mimeType = "text/x-java", service = CodeGenerator.Factory.class)
public static class Factory implements CodeGenerator.Factory {
public List<? extends CodeGenerator> create(Lookup context) {
return Collections.singletonList(new ActionPerformedGenerator(context));
}
}
public String getDisplayName() {
return "Action Performed Generator";
}
public void invoke() {
//do something with the text component...
}
}
