Qml-ButtonGroup的使用

ButtonGroup属性

1. ButtonGroup是一个非可视化，用于管理一组可互斥勾选的按钮；如常见的RadioButton、CheckBox等
2. 属性buttons：存放管理的Button列表
3. 属性checkedButton：标记当前勾选的按钮
4. 属性**exclusive **：是否互斥，默认为true
5. 附加属性**group **:在Button中使用，将Button 加入到ButtonGroup中
6. 信号clicked:ButtonGroup中有按钮按下时，发送此信号
7. 方法void addButton(AbstractButton button):往ButtonGroup中添加按钮
8. 方法void removeButton(AbstractButton button):移除ButtonGroup中添加按钮

ButtonGroup的实例代码

import QtQuick
import QtQuick.Controls//ButtonGroup -- QtObject -- QObject
//ButtonGroup 有附加属性 group;主要用于管理一组互斥的按钮,非可视化组件Item {id: itemTransform//ButtonGroup 不继承于Item，非可视乎组件ButtonGroup{id:idButGroupexclusive: true                     //此属性默认trueComponent.onCompleted: {idButGroup.addButton(idRadio4);}onClicked:(button)=>{console.log("button text = " ,button.text, " button checkstate = ",button.checked);if(button === idButGroup.checkedButton){console.log("checkebButton equal")}}}Column{id:idCol1spacing: 10anchors.left: parent.leftanchors.top: parent.topanchors.margins: 10RadioButton{id:idRadio1checked: truetext: "Radio1"ButtonGroup.group: idButGroup               //将RadioButton 添加到ButtonGrop中}RadioButton{id:idRadio2checked: truetext: "Radio2"ButtonGroup.group: idButGroup}RadioButton{id:idRadio3checked: truetext: "Radio3"ButtonGroup.group: idButGroup}RadioButton{id:idRadio4text: "Radio4"}CheckBox{id:idChecktext:"check"ButtonGroup.group: idButGroup}}}

ButtonGroup实例代码运行结果如下：
