[PyQt] Updating Qlabel in widget

2011-08-25 Thread uahmed 
Hi

I want to update the Qlabel after the widget is made , Problem is that
updating is base on counter so i call that function after 4 seconds , but
when it by pass the if statment it go through all the commands give me no
errors but it does not update the widet although if i dont putt if
statment all lines are executed and Qlabel update too  . Can you please tell
me where i am wrong

Here is code

import sys,os
from functools import partial
from PyQt4 import QtGui, QtCore
import time


class main():

def f2(self):
print f2
global count
count +=1
if ( count == 2):
msg_label[user] = QtGui.QLabel(update,widget)
msg_label[user].setGeometry(10, 10, 100, 100)
print count
QtCore.QTimer.singleShot(4000, self.f2)


app = QtGui.QApplication(sys.argv)
widget = QtGui.QWidget()
layout = QtGui.QVBoxLayout()
buttons = {}
count = 0
msg_label = {}
sk = main()
sk.f2()
widget.show()
sys.exit(app.exec_())

Don't recreate the widget over and over again. 

Create it once, and just change the label with setText().

hi

Thanks for the reply , QLabel will be created once only when count is equal
to 2 . Firstly i was thinking same that i make Qlabel first and then recall
them and change only text but if i do that then i have to create nearly
40-60 Qlabel to cover all the loop holes so i need to create it on run time
to avoid making lots of Qlabels
