## Package javax.swing.plaf.metal Description

Provides user interface objects built according to the Java look and feel (once codenamed Metal), which is the default look and feel.

These classes are designed to be used while the corresponding `LookAndFeel` class has been installed (`UIManager.setLookAndFeel(new XXXLookAndFeel())`). Using them while a different `LookAndFeel` is installed may produce unexpected results, including exceptions. Additionally, changing the `LookAndFeel` maintained by the `UIManager` without updating the corresponding `ComponentUI` of any `JComponent`s may also produce unexpected results, such as the wrong colors showing up, and is generally not encouraged.

Note: Most of the Swing API is not thread safe. For details, see Threads and Swing, a section in The Java Tutorial.

Since:
  1.2
