# Annotation Interface SwingContainer

@Target(TYPE) @Retention(RUNTIME) public @interface SwingContainer
An annotation used to specify some swing-related information for the automatically generated `BeanInfo` classes. This annotation is not used if the annotated class has a corresponding user-defined `BeanInfo` class, which does not imply the automatic analysis.

The `isContainer` `feature attribute` was introduced primarily for the Swing library. All Swing components extend the `Container` class by design, so the builder tool assumes that all Swing components are containers. The `BeanInfo` classes with the `isContainer` attribute allow to directly specify whether a Swing component is a container or not.
