| What is this project good for? |

| specifications, etc. |
| </hint> |
| </question> |

| <answer id="arch-what"> |
| The plaf library consists primarily of code that used to be in core. What it does: |
| <ul> |
| <li>Installs a custom look and feel if a custom look and feel class is passed to it</li> |
| <li>Sets the correct fonts in the Swing UIDefaults if a custom fontsize is desired for the application's UI</li> |
| <li>Loads a UI theme if a URL for the theme file (no format changes since NetBeans 3.4) is passed to it</li> |
| <li>Installs custom UI keys and values used by other components of NetBeans, such as colors and UI delegate class names used by |
| other parts NetBeans. Examples of these: |
| <ul> |
| <li>Tab control UI delegate class name, depending on the look and feel, for the window system</li> |
| <li>Definitions of colors which the tab control, property sheet and output window will use, if present in |
| UIDefaults, to color themselves in accordance with the UI spec for them on a given look and feel</li> |
| <li>Custom border implementations NetBeans uses for scroll panes to reduce "border-buildup"</li> |
| <li>A custom implementation of ToolbarUI which NetBeans uses for its toolbars, and a custom UI for |
| toolbar buttons which sizes them correctly (GTK and Aqua only, currently)</li> |
| <li>Insets definition for the editor scrollbar, used to get the height of the upper and lower button of the scrollbar |
| for purposes of the Error Stripe. The appropriate key value is "Nb.Editor.ErrorStripe.ScrollBar.Insets". |
| </li> |
| </ul> |
| </li> |
| <li>Compensate for missing elements on some (GTK) look and feels, which standard Swing code expects to be |
| present, i.e. UIManager.getColor ("control"), to enable older code to run unmodified on newer |
| look and feels.</li> |
| </ul> |
| |
| |
| Its API consists of a single method, org.netbeans.swing.plaf.Startup.run (Class lookAndFeel, int fontSize, URL themeFile), |
| which should be called early in NetBeans startup sequence by core, to initialize UIDefaults values before any main window |
| GUI is constructed. It provides a minimal SPI in the form of the abstract class LFCustoms, which an alternate look and |
| feel could use to provide lists of keys and values which should be installed into UIDefaults, via the mechanism documented |
| in the documentation for LFCustoms. |

| <!-- |
| <question id="deploy-packages"> |
| Are packages of your module made inaccessible by not declaring them |
| public? |
| |
| <hint> |
| NetBeans module system allows restriction of access rights to |
| public classes of your module from other modules. This prevents |
| unwanted dependencies of others on your code and should be used |
| whenever possible (<a href="http://www.netbeans.org/download/apis/org/openide/doc-files/upgrade.html#3.4-public-packages"> |
| public packages |
| </a>). |
| </hint> |
| </question> |
| --> |
| <answer id="deploy-packages"> |
| No. There is one root package containing the API, and several per-look-and-feel packages |
| containing implementations of standard Swing UI delegates (such as a custom toolbar UI for |
| Aqua and GTK look and feels), and custom implementations of Border and such. Swing's mechanism |
| for loading a UI delegate is by fetching the UI class name from UIDefaults and creating an |
| instance of that class, so the UI delegates must be publicly accessible for Swing to be able |
| to load them. |
| </answer> |

| <!-- |
| <question id="deploy-shared"> |
| Do you need to be installed in the shared location only, or in the user directory only, |

| Installation location shall not matter, if it does explain why. |
| Consider also whether <code>InstalledFileLocator</code> can help. |
| </hint> |
| </question> |
| --> |
| <answer id="deploy-shared"> |
| It is a library, not a module, because its code must run very early in the startup sequence, |
| before other GUI is constructed, so that all GUIs will have the correct colors, borders, UI |
| delegates, etc. All of this was formerly done directly in core. |

| <!-- |
| <question id="exec-component"> |
| Is execution of your code influenced by any (string) property |
| of any of your components? |
| |
| <hint> |
| Often <code>JComponent.getClientProperty</code>, <code>Action.getValue</code> |
| or <code>PropertyDescriptor.getValue</code>, etc. are used to influence |
| a behaviour of some code. This of course forms an interface that should |
| be documented. Also if one depends on some interface that an object |
| implements (<code>component instanceof Runnable</code>) that forms an |
| API as well. |
| </hint> |
| </question> |
| --> |
| <answer id="exec-component"> |
| For testing purposes only, the system property "nb.forceui" can be used to |
| load NetBeans customizations for a different look and feel (such as loading the custom |
| Aqua UI delegates on Windows). The only purpose for this flag is to enable |
| development/bug fixing and minimal testing when a developer is working on a machine |

| The module initializes proper Look&Feel. The decision is done |
