To display system clock time in LCD format
I just want to display system clock time in LCD format, also want the time to be displayed with the format of hh:mm:ss ,my code is as following ,but when I run it ,it is out of my expectaions ，so anyone can explain why ?

@import sys
from PyQt4 import QtGui, QtCore

class Example(QtGui.QWidget):

def __init__(self): 
    super(Example, self).__init__() 
    self.initUI() 
    timer = QtCore.QTimer(self) 
    timer.timeout.connect(self.showlcd) 
    timer.start(1000) 
    self.showlcd() 

def initUI(self): 
    
    self.lcd = QtGui.QLCDNumber(self) 
    self.setGeometry(30, 30, 800, 600) 
    self.setWindowTitle('Time') 

    vbox = QtGui.QVBoxLayout() 
    vbox.addWidget(self.lcd) 
    self.setLayout(vbox) 

    self.show() 
    
def showlcd(self): 
    time = QtCore.QTime.currentTime() 
    text = time.toString('hh:mm:ss') 
    self.lcd.display(text)

def main():

app = QtGui.QApplication(sys.argv) 
ex = Example() 
sys.exit(app.exec_())

if name == 'main':
main()

...
@text = time.toString('hh:mm')@
[/quote]You want hh:mm:ss, but you wrote hh:mm. Is that the cause? If not, please describe what happens when you run your program, and why "it is out of my expectaions".

doesn't work ? why?

-Hmm, I just realized, QLCDNumber can only display numbers. It can't display ":"-

Edit: Sorry, yes it can: http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qlcdnumber.html

But, you need to describe what you see. Otherwise, I can't guess what's wrong.

You need to set the digit count on the LCD to have enough room for all 8 characters of the system time "hh:mm:ss". The default digit count is 5, thus why you are only seeing "mm:ss". I did something very similar a while back as follows:

@
from PyQt4.QtGui import QApplication, QWidget, QVBoxLayout, QLCDNumber
from PyQt4.QtCore import QTime

class SystemClock(QWidget):
def init(self, parent=None):
QWidget.init(self, parent)

    self.setWindowTitle("System Clock")
    self.resize(640,240)

    l=QVBoxLayout(self)
    self.lcd=QLCDNumber(self, digitCount=8)
    l.addWidget(self.lcd)

    self.startTimer(1000)

def timerEvent(self, e): 
    self.lcd.display(QTime.currentTime().toString("hh:mm:ss"))

if name=="main":
from sys import argv, exit
a=QApplication(argv)
s=SystemClock()
s.show()
exit(a.exec_())
