直播短视频系统，当前日期选择控件应用

直播短视频系统，当前日期选择控件应用实现的相关代码
代码实现较为简单，没有过多需要介绍的，控件加载会自动获取当前日期，转动拨盘会根据当前年、月匹配当月天数，代码如下，直接复制到Qml中加载就可以使用了。代码如下：

import QtQuick 2.1
import QtQuick.Controls 2.4

Rectangle{
id:dateRectangle
color: "#00000000"
border.color: "#38d3dc"
property date date
property var monthsList: [1,2,3,4,5,6,7,8,9,10,11,12]
property color labelColor: "#f48fb1"
property var monthS: [1,3,5,7,8,10,12]
property string year: yearsTumbler.currentItem.text
property string month: monthsTumbler.currentItem.text
property string day: daysTumbler.currentItem.text

Row {
anchors.fill: parent
Tumbler {
id: yearsTumbler
width:parent.width/3
height: parent.height
wheelEnabled: true
font.pointSize: 16
font.family: "微软雅黑"
onCurrentItemChanged: {
var year = currentItem.text
var month = monthsTumbler.currentIndex+1
getDays(year,month)
}

}
Label{
width: 20
text: "年"
font.bold: true
anchors.verticalCenter: parent.verticalCenter
font.pointSize: 13
font.family: "微软雅黑"
color: labelColor
}

Tumbler {
id: monthsTumbler
width:parent.width/3-30
height: parent.height
model: monthsList
font.pointSize: 16
font.family: "微软雅黑"
onCurrentIndexChanged: {
var year = yearsTumbler.currentItem.text
var month = currentIndex+1
getDays(year,month)
}
}
Label{
width: 20
text: "月"
font.bold: true
anchors.verticalCenter: parent.verticalCenter
font.pointSize: 13
font.family: "微软雅黑"
color: labelColor
}
Tumbler {
id: daysTumbler
width:parent.width/3-30
height: parent.height
font.pointSize: 16
font.family: "微软雅黑"
}
Label{
width: 20
text: "日"
font.bold: true
anchors.verticalCenter: parent.verticalCenter
font.pointSize: 13
font.family: "微软雅黑"
color: labelColor
}
}

Component.onCompleted: {
initialize()
}

function initialize(){//初始化控件
var yearsList=[]
date = new Date()
var year = date.getFullYear()
for(var i=0;i<8;i++){
var y = year-i
yearsList.push(y)
}
yearsTumbler.model = yearsList
yearsTumbler.currentIndex = 0
var month = date.getMonth()
monthsTumbler.currentIndex = month
getDays(year,month+1)
var day = date.getDate()
daysTumbler.currentIndex = day-1
}
function getDays(year,month){//获取当月天数
if(monthS.indexOf(month)>-1){
addDays(31)
}else if(month>2){
addDays(30)
}else{
if(year%4==0){
addDays(29)
}else{
addDays(28)
}
}
}
function addDays(days){
var daysList = []
for(var i=1;i<=days;i++){
daysList.push(i)
}
daysTumbler.model = daysList
}
}
