+/**
+ * The VScrollBar (vertical ScrollBar) control lets you control
+ * the portion of data that is displayed when there is too much data
+ * to fit in a display area.
+ *
+ * This control extends the base ScrollBar control.
+ *
+ * <p>Although you can use the VScrollBar control as a stand-alone control,
+ * you usually combine it as part of another group of components to
+ * provide scrolling functionality.</p>
+ *
+ * <p>A ScrollBar control consist of four parts: two arrow buttons,
+ * a track, and a thumb.
+ * The position of the thumb and the display of the arrow buttons
+ * depend on the current state of the ScrollBar control.
+ * The ScrollBar control uses four parameters to calculate its
+ * display state:</p>
+ *
+ * <ul>
+ * <li>Minimum range value</li>
+ * <li>Maximum range value</li>
+ * <li>Current position - must be within the
+ * minimum and maximum range values</li>
+ * <li>Viewport size - represents the number of items
+ * in the range that you can display at one time. The
+ * number of items must be less than or equal to the
+ * range, where the range is the set of values between
+ * the minimum range value and the maximum range value.</li>
+ * </ul>
+ *
+ * @mxml
+ *
+ * <p>The <code><mx:VScrollBar></code> tag inherits all the
+ * tag attributes of its superclass, and adds the following tag
attributes:</p>
+ *
+ * <pre>
+ * <mx:VScrollBar
+ * <strong>Styles</strong>
+ * repeatDelay="500"
+ * repeatInterval="35"
+ *
+ * <strong>Events</strong>
+ * scroll="<i>No default</i>"
