Qt4 window icon won't display

Hi,

Just learning PyQt4 to build a GUI, but I can't get the window icon to display, it worked on a raspberry pi, but not on Linux Mint Sarah?

Code:

#!/usr/bin/python3

# input.py
# Module for getting userdata via a GUI using PyQt4

import sys
from PyQt4 import QtGui

class Window(QtGui.QMainWindow):

    def __init__(self):
        super(Window, self).__init__()
        self.setGeometry(50, 50, 500, 300)
        self.setWindowTitle("GUI testing")
        self.setWindowIcon(QtGui.QIcon('./tick.png'))
        self.show()



app = QtGui.QApplication(sys.argv)
GUI = Window()
sys.exit(app.exec())

So this is in a folder of it's own, and the png file is in the same folder. I have been told about absolute paths, and I have tried that also but still it does not show up, any ideas please?

Regards

Works fine here (Debian Sid/KDE).

Try loading a system icon or test your png file:

Code:

        . . .
        self.setWindowTitle("GUI testing")
        icon =QtGui.QImage('./tick.png')
        print(icon.isNull())        
        self.setWindowIcon(QtGui.QIcon('./tick.png'))
        . . .
