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");
}
