Feel is an appropriate word as user interfaces often leave customers with an emotional impression. A user interface can be engaging and pleasing to use. Alternatively, an interface can put users into a bad mood by forcing them to tackle needless complexity, cryptic controls and an counterintuitive flow.
Programmatically Setting the Look and Feel
Note: If you are going to set the L&F, you should do it as the very first step in your application. Otherwise you run the risk of initializing the Java L&F regardless of what L&F you've requested. This can happen inadvertently when a static field references a Swing class, which causes the L&F to be loaded.
Specifying the Look and Feel: Command Line
You can specify the L&F at the command line by using the -D flag to set the swing.defaultlaf property. For example:
Specifying the Look and Feel: swing.properties File
Yet another way to specify the current L&F is to use the swing.properties file to set the swing.defaultlaf property. This file, which you may need to create, is located in the lib directory of Sun's Java release (other vendors of Java may use a different location).
How the UI Manager Chooses the Look and Feel
Here are the look-and-feel determination steps that occur when the UI manager needs to set a L&F:
Changing the Look and Feel After Startup
You can change the L&F with setLookAndFeel even after the program's GUI is visible. To make existing components reflect the new L&F, invoke the SwingUtilities updateComponentTreeUI method once per top-level container. Then you might wish to resize each top-level container to reflect the new sizes of its contained components. For example:
An Example
In the following example, LookAndFeelDemo.java, you can experiment with different Look and Feels. The program creates a simple GUI with a button and a label. Every time you click the button, the label increments.
Themes
Themes were introduced as a way of easily changing the colors and fonts of the cross-platform Java (Metal) Look and Feel. In the sample program, LookAndfeelDemo.java, listed above, you can change the theme of the Metal L&F by setting the THEME constant on line 23 to one of three values:
Overview
Pluggable look and feel is a mechanism used in the Java Swing widget toolkit allowing to change the look and feel of the graphical user interface at runtime.
Swing allows an application to specialize the look and feel of widgets by modifying the default (via runtime parameters), deriving from an existing one, by creating one from scratch, or, beginning with J2SE 5.0, by using the skinnable synth look and feel, which is configured with an X…
Architecture
The corresponding API includes:
• Hooks in Swing widgets to interact with their look and feel. Each widget defined in Swing can delegate its "painting" to its associated user interface classes called UI delegates.
• An API to manage existing look-and-feel definitions. This API allow to set the look and feel or switch from look and feels at runtime.
Examples of look and feels
The Java platform comes with several bundled look and feels:
• A default cross-platform look and feel, called Metal (see MetalLookAndFeel). This look and feel comes with several themes:
