使用qt搭建一个简易的闹钟系统

#include "second.h"
#include "ui_second.h"

second::second(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::second)
{

    ui->setupUi(this);
    this->setWindowFlag(Qt::FramelessWindowHint);
    this->setAttribute(Qt::WA_TranslucentBackground);
    timeid1 = startTimer(1000);
    ui->lab_currenttime->setAlignment(Qt::AlignCenter);

}

second::~second()
{
    delete ui;
}

void second::timerEvent(QTimerEvent *e)
{
    if(e->timerId() == timeid1)
    {
        QTime qt = QTime::currentTime();
        QString st = qt.toString();
        ui->lab_currenttime->setText(st);
        if(alarmtime==st)
        {
            QString say = ui->lab_say->text();
            speaker = new QTextToSpeech(this);
            speaker->say(say);
        }
    }
}

void second::start()
{
    this->show();
}



void second::on_btn_settime_clicked()
{
    alarmtime = ui->lineEdit_alarmtime->text();
    QMessageBox::information(this,"tip","闹钟设置成功");
}
