代码如下:
main.qml文件:import QtQuick 2.5
import QtQuick.Window 2.2
import QtQuick.Controls 1.2
Window {
visible: true
width: 640
height: 480
title: qsTr("Hello World")
MainForm {
anchors.fill: parent
a.onClicked: {one.visible=true;two.visible=false;three.visible=false;state="pic1"}
b.onClicked: {one.visible=false;two.visible=true;three.visible=false;state="pic2"}
c.onClicked: {one.visible=false;two.visible=false;three.visible=true;state="pic3"}
states: [//定义一个三个成员的状态数组
State {
name: "pic1"
PropertyChanges {
target: img
source:"http://xxx.fishc.com/forum/201702/28/084008zx2n7ntjgx7ljx7o.jpeg"
}
},State {

}
}
]

}
}
MainForm.ui.qml文件:import QtQuick 2.5
