今天参与了代码编写，编写了奖品代码，即设置奖品等内容，编写很艰难，学习了很多东西，代码如下

#include "setwidget.h"
#include<QHBoxLayout>
#include<QVBoxLayout>
#include<QMessageBox>
#include<QTime>
#include<QDebug>
SetWidget::SetWidget(QWidget *parent) : QWidget(parent)
{
    qsrand(QTime(0,0,0).secsTo(QTime::currentTime()));//产生随机种子

    this->setFixedSize(400,500);

    //设置按钮
    this->Oksetbutton=new QPushButton("确定设置");
     this->Oksetbutton->setFixedSize(60,50);
    this->retbutton=new QPushButton("返回上级");
     this->retbutton->setFixedSize(60,50);
    auto Hlayout=new QHBoxLayout;
    Hlayout->addWidget(retbutton);
    Hlayout->addWidget(Oksetbutton);

    //设置一二三等奖的显示和布局
    this->Label1=new PrizeLabel;
    Label1->prizeHint.setText("一等奖");
    this->Label2=new PrizeLabel;
    Label2->prizeHint.setText("二等奖");
    this->Label3=new PrizeLabel;
    Label3->prizeHint.setText("三等奖");

    //设置满足金额限制
    auto widget=new QWidget;
    widget->setFixedSize(200,60);
    QLabel *widgethint=new QLabel("满足最低金额:");
    widgetedit=new QLineEdit;
    QHBoxLayout *widgetlayout=new QHBoxLayout;
    widgetlayout->addWidget(widgethint);
    widgetlayout->addWidget(widgetedit);
    widget->setLayout(widgetlayout);

    auto Vlayout=new QVBoxLayout;
    Vlayout->addWidget(Label1);
    Vlayout->addWidget(Label2);
    Vlayout->addWidget(Label3);
     Vlayout->addWidget(widget);
    Vlayout->addLayout(Hlayout);
    this->setLayout(Vlayout);

    this->movie=new QMovie(":/new/prefix1/01.gif");
    this->movlabel=new QLabel;
    this->movlabel->setFixedSize(739,357);
    this->movlabel->setFrameShape(QFrame::NoFrame);
    this->movlabel->setMovie(movie);

    connect(retbutton,&QPushButton::clicked,[this](){
         emit retturnSig();//发出信号
    });

    connect(Oksetbutton,&QPushButton::clicked,[this](){

        //获取到编辑框的值
        Label1str=this->Label1->GetWinningprize();
        Label1value=this->Label1->GetWinningodds();

        Label2str=this->Label2->GetWinningprize();
        Label2value=this->Label2->GetWinningodds();

        Label3str=this->Label3->GetWinningprize();
        Label3value=this->Label3->GetWinningodds();

        //如果机率设置不合法
        if((Label1value+Label2value+Label3value)!=100||(Label1value+Label2value+Label3value)>100){
            QMessageBox::information(this,"错误提示","机率总和大于100或不等于100");
            return;
        }

        this->swidget.show();
        this->hide();
    });

    connect(&swidget,SIGNAL(startfinished()),this,SLOT(StartGames()));

    //触发定时器
    connect(&timer,&QTimer::timeout,[this](){
        this->timer.stop();
        this->movie->stop();
        this->movlabel->hide();

        qDebug()<<"随机数位:"<<randomnum;
        //判断是谁获奖了 并显示信息
        if(0<randomnum&&randomnum<=Label1value){
                QMessageBox::information(this,QString("一等奖"),QString("奖品:%1").arg(Label1str));
        }else if(Label1value<=randomnum&&randomnum<=(Label1value+Label2value)){
                QMessageBox::information(this,QString("二等奖"),QString("奖品:%1").arg(Label2str));
        }else if((Label1value+Label2value)<=randomnum&&randomnum<=(Label1value+Label2value+Label3value)){
                 QMessageBox::information(this,QString("三等奖"),QString("奖品:%1").arg(Label3str));
        }
    });

    connect(&swidget,&startwidget::retfinished,[this](){
        this->show();
    });
}

//开始抽奖逻辑
void SetWidget::StartGames()
{
    //随机产生个1-100的数值
    randomnum=qrand()%100+1; //每次开始随机产生一个1-100的数值

    this->timer.start(3000);//三秒开始定时器

    //播放抽奖GIF
    this->movlabel->show();
    this->movie->start();
    this->hide();
    //qDebug()<<"str:"<<Labelstr<<" value:"<<Labelvalue;
}
