Java Screen.getBounds方法代码示例

/**
     * 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.
