Module
Most features in NetBeans IDE are found within a single module.
If a feature is complex and consists of different parts, it consists of multiple modules.
A module is:
– a JAR file
– with special manifest entries
– distributed as an NBM file

Workshop
Let’s create a module!

Actions
Actions are invoked from menu items, toolbar buttons, and keyboard shortcuts.
Actions consist of
– ActionListener
– Display name
– Icon
Some actions are always enabled and some actions are contextually enabled.

Actions
Actions are invoked from menu items, toolbar buttons, and keyboard shortcuts.
Actions consist of
– ActionListener
– Display name
– Icon
Some actions are always enabled and some actions are contextually enabled.
Task: Find two always enabled actions and two contextually enabled actions
…and explain why!
20
Filesystem
Features in modules are registered in an XML file called “layer.xml” file.
Each module has at most one “layer.xml” file.
Entries in the “layer.xml” file:
– Come from annotations in Java classes.
– Come from manually typing in the file.
When NetBeans IDE starts, it merges all “layer.xml” files and creates the filesystem.
The filesystem has fixed folders, e.g., “Menu” and “Toolbars”.
21
Workshop
Let’s create an Action and register it in the Filesystem!
22
Workshop
Try to create an Action without using a wizard!
23
Workshop
Create a new Module that registers an Action in the Toolbar!
24
TopComponents
TopComponents are windows.
Windows are displayed in modes, i.e., positions or tabs.
Predefined modes include “editor”, “explorer”, “output”, and “properties”.
Annotations on the TopComponent define its default Mode.

Annotations on the TopComponent define its default Mode.
Task: Identify three windows displayed by default in
the “explorer”, “editor”, and “output” mode.

Options Window
The Options window is a centralized dialog for all customizations in NetBeans IDE.
Each module can contribute new panels to the Options window.
There are primary panels and secondary panels.
Changes in the Options window can be persisted across restarts of NetBeans IDE.

Changes in the Options window can be persisted across restarts of NetBeans IDE.
Task: Go to the Miscellaneous category in the Options window and
make the tabs of NetBeans IDE appear along the bottom and
then experiment with other settings you find there.

Workshop
Let’s create a new Options panel!

Lookup
Lookup provides context sensitivity to NetBeans IDE.
Task: Make a change in an editor and look at what happens to the Save button.
Click the Save button and notice what happens.
Do you think the Save button is in the same module as the editor?
Try to make some guesses about how it works.

Do you think the Save button is in the same module as the editor?
Try to make some guesses about how it works.
Context sensitivity is provided by an event listening mechanism:
– The Save action is listening to the global context for a typed object.
– When a change is made in the editor, the typed object is published into the global context.
– The Save action calls a method on the type.
33
Workshop
Let’s listen to the global context for Projects!
34
Workshop
Display information about all the selected projects
in a window displayed in the Properties mode.
