Example 6 with ScrollBar

use of org.apache.pivot.wtk.ScrollBar in project pivot by apache.

the class TerraScrollBarSkin method mouseDown.

 * Initiates automatic block scrolling. This only happens if the handle is
 * visible since whether the user clicked before or after the handle
 * determines the direction of the scrolling.
 *
 * @param component The scroll bar.
 * @param button The button that was pressed.
 * @param x The x-coordinate of the event in the scroll bar's coordinate
 * space.
 * @param y The y-coordinate of the event in the scroll bar's coordinate
 * space.
