在PYQT4中使用日期編輯的實時循環（時鐘）

Question

我的問題是：如何在PYQT4中使用qtimeEdit來循環更新&，因此它總是顯示當前時間。基本上，我希望它的功能就像Windows任務欄的時間和日期一樣。

例如：

from PyQt4 import QtCore, QtGui 
from PyQt4 import phonon 
import sys 
import os 


try: 
    _fromUtf8 = QtCore.QString.fromUtf8 
except AttributeError: 
    def _fromUtf8(s): 
     return s 

try: 
    _encoding = QtGui.QApplication.UnicodeUTF8 


    def _translate(context, text, disambig): 
     return QtGui.QApplication.translate(context, text, disambig, _encoding) 
except AttributeError: 
    def _translate(context, text, disambig): 
     return QtGui.QApplication.translate(context, text, disambig) 


class Ui_MainWindow(object): 
    def setupUi(self, MainWindow): 
     MainWindow.setWindowFlags(QtCore.Qt.WindowContextHelpButtonHint) 
     MainWindow.setObjectName(_fromUtf8("MainWindow")) 
     MainWindow.resize(885, 450) 
     MainWindow.setMinimumSize(QtCore.QSize(885, 450)) 
     MainWindow.setMaximumSize(QtCore.QSize(885, 491)) 
     MainWindow.setMouseTracking(False)  self.timeEdit = QtGui.QTimeEdit(self.splitter) 

     self.timeEdit.setCursor(QtGui.QCursor(QtCore.Qt.BusyCursor)) 
     self.timeEdit.setAutoFillBackground(True) 
     self.timeEdit.setWrapping(True) 
     self.timeEdit.setFrame(True) 
     self.timeEdit.setAlignment(QtCore.Qt.AlignCenter) 
     self.timeEdit.setReadOnly(True) 
     self.timeEdit.setButtonSymbols(QtGui.QAbstractSpinBox.NoButtons) 
     self.timeEdit.setKeyboardTracking(True) 
     self.timeEdit.setObjectName(_fromUtf8("timeEdit")) 


    def retranslateUi(self, MainWindow): 

     Today = QtCore.QDate.currentDate() 
     self.dateEdit.setDate(Today) 

     self.ui.timeEdit = QtGui.QTimeEdit(self) 
     self.timeEdit.setDisplayFormat("hh:mm:ss AP") 
     self.updateTime() 
     self.timer = QtCore.QTimer(self) 
     self.timer.timeout.connect(self.updateTime) 
     self.timer.start(1000) 



    def updateTime(self): 
     current = QtCore.QDateTime.currentDateTime() 
     self.timeEdit.setTime(current.time()) 




class ControlMainWindow(QtGui.QMainWindow): 
    def __init__(self, parent=None): 
     super(ControlMainWindow, self).__init__(parent) 
     self.ui = Ui_MainWindow() 
     self.ui.setupUi(self) 


    def closeEvent(self, event): 
     result = QtGui.QMessageBox.critical(self, 
              "Confirm Exit...", 
              "Are you sure you want to exit ?", 
              QtGui.QMessageBox.Yes | QtGui.QMessageBox.No) 
     event.ignore() 

     if result == QtGui.QMessageBox.Yes: 
      event.accept() 

    def VoluemChanger(self, audioOutput): 
     self.ui.volumeSlider.setAudioOutput(self.ui.videoPlayer.audioOutput()) 



if __name__ == '__main__': 
    app = QtGui.QApplication(sys.argv) 
    mySW = ControlMainWindow() 
    mySW.show() 
    sys.exit(app.exec_())

試試這個代碼，執行時將觸發每一秒的定時器，在該點時讀取和更新。

import sys 
from PyQt4 import QtCore, QtGui 


class Widget(QtGui.QWidget): 
    def __init__(self): 
     super(Widget, self).__init__() 

     # Uncomment if you want to change the language 
     # self.setLocale(QtCore.QLocale(QtCore.QLocale.Spanish, QtCore.QLocale.Peru)) 
     self.verticalLayout = QtGui.QVBoxLayout(self) 
     self.dateEdit = QtGui.QDateEdit(self) 
     self.dateEdit.setDisplayFormat("MMM dd yyyy") 
     self.verticalLayout.addWidget(self.dateEdit) 
     self.timeEdit = QtGui.QTimeEdit(self) 
     self.timeEdit.setDisplayFormat("hh:mm:ss AP") 
     self.verticalLayout.addWidget(self.timeEdit) 
     self.updateTime() 
     self.timer = QtCore.QTimer(self) 
     self.timer.timeout.connect(self.updateTime) 
     self.timer.start(1000) 

    def updateTime(self): 
     current = QtCore.QDateTime.currentDateTime() 
     self.dateEdit.setDate(current.date()) 
     self.timeEdit.setTime(current.time()) 


def main(): 
    app = QtGui.QApplication(sys.argv) 
    w = Widget() 
    w.show() 
    sys.exit(app.exec_()) 


if __name__ == '__main__': 
    main() 

輸出：
