UIManager color keys - JFormDesigner color palettes. I'm short on time today, but while I'm in this neighborhood, let me say that I got started on this quest while (a) working on a new Java Swing application, and (b) running into the color palettes that were displayed by a JFormDesigner color chooser.

Before you jump into Java GUIs, there are a few things you should know. Java comes with three sets of classes for creating GUI applications:

• The Abstract Window Toolkit (AWT): The original set of classes, dating back to JDK 1.0.

Classes in this set belong to packages whose names begin with java.awt. Components in this set have names like Button, TextField, Frame, and so on.

Each component in an AWT program has a peer — a companion component that belongs to the computer’s own operating system. For example, when you create an AWT ButtonPcengines support. , a Mac computer creates its own kind of button to be displayed on the user’s screen. When the same program runs on a Windows computer, the Windows computer creates a different kind of button (a Windows button) to display on the computer’s screen. The Java code in the AWT interacts with the Mac or Windows button, adding additional functionality where functionality is needed.

The AWT implements only the kinds of components that were available on all common operating systems in the mid-1990s. So, using AWT, you can add a button to your application, but you can’t easily add a table or a tree.

• Java Swing: A set of classes created to fix some of the difficulties posed by the use of the AWT. Swing was introduced in J2SE 1.2.

Classes in this set belong to packages whose names begin with javax.swing. Components in this set have names like JButton, JTextField, JFrame, and so on.

Unlike an old AWT component, a Swing component has no peer. When you create a JButton in your Java program, the computer’s operating system doesn’t create a button of its own. Instead, the JButton that you see is a pure Java object. Java’s visual rendering code draws this object on a window. This is both good news and bad news. The good news is, a Swing program looks the same on every operating system. In a Swing program, you can create table components and tree components because Java simply draws them in the computer’s window. The bad news is, Swing components aren’t pretty. A JButton looks primitive and crude compared to a Mac button or a Windows button.

Java’s Swing classes replace some (but not all) of the classes in the older AWT. To use some of the Swing classes, you have to call on some of the old AWT classes.

• JavaFX: The newest set of GUI classes in Oracle standard Java. JavaFX comes with new(er) versions of Java 7 and with all later versions of Java.

Classes in this set belong to packages whose names begin with javafx.

Midiman usb keystation 49 driver for mac. JavaFX supports over 60 kinds of components. (Sure, you want a Button component. But do you also want an Accordion component? JavaFX has one.) In addition, JavaFX supports multitouch operations and takes advantage of each processor’s specialized graphics capabilities.

  An implementation of a 'push' button.

  Buttons can be configured, and to some degree controlled, by Actions. Using an Action with a button has many benefits beyond directly configuring a button. Refer to Swing Components Supporting Action for more details, and you can find more information in How to Use Actions, a section in The Java Tutorial.

  See How to Use Buttons, Check Boxes, and Radio Buttons in The Java Tutorial for information and examples of using buttons.

  Warning: Swing is not thread safe. For more information see Swing's Threading Policy.

  Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans^TM has been added to the java.beans package. Please see XMLEncoder.

      See Also:

      JComponent.registerKeyboardAction(java.awt.event.ActionListener, java.lang.String, javax.swing.KeyStroke, int)

    • paramString

      Returns a string representation of this JButton. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.

      Overrides:

      paramString in class AbstractButton

      Returns:

      a string representation of this JButton

    • getAccessibleContext

      Gets the AccessibleContext associated with this JButton. For JButtons, the AccessibleContext takes the form of an AccessibleJButton. A new AccessibleJButton instance is created if necessary.

      Specified by:

      getAccessibleContext in interface Accessible

      Overrides:

      getAccessibleContext in class JComponent

      Returns:
