详细描述

The DPageIndicator class provides indicator of which page is currently showing.

\inmodule dtkwidget

DPageIndicator 类提供了一种用来指示一组元素中当前可见元素索引的控件.

DPageIndicator is control that displays a horizontal series of dots, each of which corresponds to a page/widget may appear on top of it.

It's inspired by UIPageControl of Apple. See \l {https://developer.apple.com/documentation/uikit/uipagecontrol}.

控件会显示了一系列的点，代表一组元素。其中每一个点固定对应于元素组中 的一个元素，元素组中的元素在一个时间点只能显示其中的一个（ 如 QStackedLayout ）， 当前显示的元素所对应的点会被高亮以告知用户元素左右（或者上下）还有多少元素可以切换。

例如下图中控制中心首页插件区域底部的指示器：

注解
此控件只用来显示当前元素位置以及层叠关系，并不能用来实际操纵元素的显示行为。
The design of this control is that it's just used to display, not to control which page is currently visible.
