In looking at the lists archives, I see that most of the participants
seem to be experienced developers. As a novice programmer I hope I am
not intruding by asking some basic questions.
I am working my way through examples in a PySide book I bought.
According to the author the example should display a 200 x 150 window,
pause 3 seconds and then display a 300 x 300 window. On my system
(Ubuntu 12.04) there is a approx 3 second delay after starting the
program and then I see the 300 x 300 window. I never see the first window.
Could someone explain to me why it does not act as described?
# Import required modules
import sys
import time
from PySide.QtGui import QApplication, QWidget
class SampleWindow(QWidget):
""" Our main window class
"""
# Constructor function
def __init__(self):
QWidget.__init__(self)
self.setWindowTitle("Sample Window")
self.setGeometry(300, 300, 200, 150)
self.setMinimumHeight(100)
self.setMinimumWidth(250)
self.setMaximumHeight(200)
self.setMaximumWidth(800)
if __name__ == '__main__':
# Exception Handling
try:
myApp = QApplication(sys.argv)
myWindow = SampleWindow()
myWindow.show()
time.sleep(3)
myWindow.resize(300, 300)
myWindow.setWindowTitle("Sample Window Resized")
myWindow.repaint()
myApp.exec_()
sys.exit(0)
except NameError:
print("Name Error:", sys.exc_info()[1])
except SystemExit:
print("Closing Window...")
except Exception:
print (sys.exc_info()[1])
Thanks, Jim
