Missing icons when running Notepad example on Raspberry Pi

The program runs without problems on my Raspberry Pi. But the menu bar shows no icons. just blank rectangles. They do work if I click on them. What could be the problem?

Open the file notepad.py and go after this:

def __init__(self, *args, **kwargs):
    super(MainWindow, self).__init__(*args, **kwargs)

add the following lines:

    icon = QIcon(os.path.join('images', 'blue-flolder-open-document.png'))
    print("availableSizes:", icon.availableSizes())

the output on the terminal should be:

availableSizes: [PyQt5.QtCore.QSize(16, 16)]

if it is different, for example:

availableSizes: []

try to replace all the occurrences of:




where path is the absolute path of your images folder for example:

path = ‘/home/USER_NAME/notepad/images’

if the notepad folder is in the USER_NAME folder.
