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 } }
