下面列出了怎么用java.awt.event.HierarchyBoundsListener的API类实例代码及写法，或者点击链接到github查看源代码。
/** Overridden to do nothing */
public void addHierarchyBoundsListener(HierarchyBoundsListener hbl) {
}
/** Overridden to do nothing */
public void addHierarchyBoundsListener(HierarchyBoundsListener hbl) {
}
/** Overridden to be a no-op for performance reasons */
@Override
public final void addHierarchyBoundsListener(HierarchyBoundsListener hbl) {
//do nothing
}
