【简单闹钟定时器的实现】PyQt6

效果图展示：

代码如下：

import sys

from PyQt6.QtGui import QPainter, QColor, QMouseEvent, QPixmap,QPen
from PyQt6.QtWidgets import QWidget, QApplication, QLabel, QLineEdit, QPushButton
from PyQt6 import uic
from PyQt6.QtCore import QPoint, QTimerEvent, QTime
from PyQt6.QtTextToSpeech import QTextToSpeech


class MyWidget(QWidget):
    def __init__(self):
        super().__init__()
        ui=uic.loadUi("./Form.ui",self)

        self.labeltime:QLabel=ui.labeltime
        self.lineEdit:QLineEdit=ui.lineEdit
        self.btn:QPushButton=ui.btn
        self.labeltext:QLabel=ui.labeltext
        self.labelstart:QLabel=ui.labelstart

        self.startTimer(1000)
        self.speecher=QTextToSpeech()

        self.btn.clicked.connect(self.btn_slot)



    def timerEvent(self, a0:QTimerEvent):
        sys_time=QTime.currentTime()
        t=sys_time.toString('hh:mm:ss')
        self.labeltime.setText(t)
        if self.labelstart.text()=='闹钟已经订好了':

            if self.labeltime.text()==self.lineEdit.text():
                    self.speecher.say(self.labeltext.text())


    def btn_slot(self):

        self.labelstart.setText('闹钟已经订好了')

if __name__ == '__main__':
    app=QApplication(sys.argv)

    myWidget=MyWidget()

    myWidget.show()

    sys.exit(app.exec())

实现该功能用到了事件机制和信号与槽的机制。
