Q : "Does anyone know why the icon (.ico) picture is not showing? "
I can confirm to have routinely used the .iconbitmap()
-method on cross-platform portable GUI-system for Linux / Win ecosystems years ago.
@DapperDuck hypothesis seems to be hard-coded right into the __doc__
-string:
>>> print root.iconbitmap.__doc__
Set bitmap for the iconified widget to BITMAP. Return
the bitmap if None is given.
Under Windows, the DEFAULT parameter can be used to set the icon
for the widget and any descendents that don't have an icon set
explicitly. DEFAULT can be the relative path to a .ico file
(example: root.iconbitmap(default='myicon.ico') ). See Tk
documentation for more information.
So the Mac-specific documentation is to be consulted.
