详细说明

PageIndicator 用于显示多个页面容器中的当前活动页面。PageIndicator 由显示页面的委托项组成。

Column {
    StackLayout {
        id: stackLayout

        Page {
            // ...
        }
        Page {
            // ...
        }
        Page {
            // ...
        }
    }

    PageIndicator {
        currentIndex: stackLayout.currentIndex
        count: stackLayout.count
    }
}

属性文档

count : int

该属性显示页数。


currentIndex : int

该属性包含当前页面的索引。


delegate : Component

该属性包含显示页面的委托项。

以下属性在每个委托的上下文中可用:

索引:int项目的索引
pressed: bool项目是否按下

interactive : bool

该属性表示控件是否是交互式的。交互式页面指示器会对按压做出反应,并自动适当更改current index

SwipeView {
    id: view
    currentIndex: pageIndicator.currentIndex
    anchors.fill: parent

    Page {
        title: qsTr("Home")
    }
    Page {
        title: qsTr("Discover")
    }
    Page {
        title: qsTr("Activity")
    }
}

PageIndicator {
    id: pageIndicator
    interactive: true
    count: view.count
    currentIndex: view.currentIndex

    anchors.bottom: parent.bottom
    anchors.horizontalCenter: parent.horizontalCenter
}

注意: 页面指示器通常很小(以避免分散用户对用户界面实际内容的注意力)。它们可能很难点击,而且用户可能不容易识别出它们是交互式的。因此,它们最好用来补充主要导航方法(如SwipeView ),而不是取而代之。
