示例1: centerDialogOnScreen
import javafx.stage.Window; //导入方法依赖的package包/类
/**
* Utility method to center a Dialog/Alert on the middle of the current
* screen. Used to workaround a "bug" with the current version of JavaFX (or
* the SWT/JavaFX embedding?) where alerts always show on the primary
* screen, not necessarily the current one.
*
* @param dialog
* The dialog to reposition. It must be already shown, or else
* this will do nothing.
* @param referenceNode
* The dialog should be moved to the same screen as this node's
* window.
