惠州如何创建JavaFX分页控件？_北大青鸟IT学校

Java是现在非常主流的编程语言之一，很多人想转行学习Java。那么如何创建JavaFX分页控件？下面就让我们一起来看看惠州北大青鸟老师是怎么回答的。

分页控件由页面内容和页面导航区域组成。

创建具有不确定页计数和当前页索引等于零的分页控件

Pagination pagination1 = new Pagination();

要创建一个5页的分页控件，当前页索引等于零

Pagination pagination2 = new Pagination(5);

要创建一个5页的分页控件，当前所选索引等于2

Pagination pagination3 = new Pagination(5, 2);
