Window System Persistence Data using barcode writer for awt control to generate, create qr code iso/iec18004 image in awt applications. Basic Infromation about Micro QR Code Try running the mo j2se QR-Code dule again. Type some text into the text eld and shut down NetBeans. Run the module yet again.

You will note that the text you entered during the previous session has been preserved.. Window System Persistence Modes There are three pe jar Quick Response Code rsistence modes a TopComponent can have: PERSISTENCE_ALWAYS, meaning that the component s state should always be saved on shutdown and restored to its current state (which may be closed) on restart; PERSISTENCE_NEVER which means that the component will never be persisted on shutdown; and PERSISTENCE_ONLY_OPENED, which is appropriate for le editors if the component is open, it will be persisted; otherwise it will not. The default persistence mode of a TopComponent is PERSISTENCE_ ALWAYS. To change it, override getPersistenceType() in your TopComponent subclass.

. Window System Persistence Data Let s have a look javabean QR Code JIS X 0510 at the les that were generated when we used the New Window Component wizard to create DemoTopComponent.. This le was creat QR Code ISO/IEC18004 for Java ed when we created the project. It contains the localized display name and description of the module. It was modi ed, when the New Window Component wizard ran, to also contain localized names for our Scratchpad component and the action that displays it.

. This is an action Quick Response Code for Java class which looks up the default instance of our component and calls open() and then requestActive() on it. This is the form le metadata which is used by the Swing GUI editor it will be omitted from the module JAR by the build script, since it is not needed at runtime; it is only used by the GUI designer in NetBeans during development..

DemoTopComponent.form 8 . The Window System This is the Java source for our TopComponent subclass. DemoTopComponentSettings.xml This is one of a p jdk qr barcode air of les that de nes the persisted default instance of DemoTopComponent. Settings les are a NetBeans le type to represent a persisted instance of some object. They are somewhat like a le containing a serialized object, but are in XML, and do not necessarily contain any serialized data by default a settings le can simply specify what class to instantiate and the system will try to do so via Class.

newInstance().. < xml version=" 1.0" encoding="UTF-8" > <!DOCTYPE settings PUBLIC "-//NetBeans//DTD Session settings 1.0//EN" "http://www."> <settings version="1.

DemoTopComponent" method="getDefault"/> </settings>. A slightly more co jboss qr barcode mmon idiom in NetBeans is .instance les, which you will learn about in 10. Their principal difference from settings les is that by specifying all of the classes and interfaces an object implements, it is possible for the system to answer questions about the type of a stored object without instantiating it to know what class it really is.

Suf ce it to say that this le instructs to create an instance of DemoTopComponent when one is needed, and to do so by calling the static getDefault() method that the wizard put in DemoTopComponent.. Window System Persistence Data DemoTopComponentWstcref.xml This is a class wh ich ties the settings le described above to a particular declaratively-de ned Mode.. < xml version=" QR Code for Java 1.0" encoding="UTF-8" > <!DOCTYPE tc-ref PUBLIC "-//NetBeans// DTD Top Component in Mode Properties 2.0//EN" "http://www."> <tc-ref version="2.

preferredID().. layer.xml This is the con gu ration le that de nes what our module installs much of the declarative runtime con guration of NetBeans is de ned in such layer les, provided by modules that want to contribute some classes or objects to the runtime con guration of the application.

If you open the JAR manifest for our demo module, you will nd a line in it that points to this layer le:.
