QML鼠标区域控制

鼠标操作使用很多，下面给出一个示例：

import QtQuick 2.4
import QtQuick.Controls 1.3
import QtQuick.Window 2.2
import QtQuick.Dialogs 1.2

Rectangle{
    id: root
     210
    height: 100

    Rectangle{
        id: rect1
         100; height:100
        color: "lightsteelblue"
        MouseArea{
            anchors.fill: parent

            onClicked: {
                rect2.visible = !rect2.visible
                console.log("visible: ", rect2.visible)
            }
        }
    }

    Rectangle{
        id: rect2
        x:110; y:0
         100; height:100
        color: "lightsteelblue"
        border.color: "lightgreen"
        border. 5
        radius: 10
    }

}
