[PyQt] QGraphicsView fails to setWindowIcon

[Dan Smith]

Hey,

I'm using sub-classed QGraphicsView's in an MDIArea I want to change the
icon of the window from 'within' the object, but it just seems to ignore
me... no errors or warnings... it just doesn't do it.

if self.world.is_dirty:
    self.setWindowIcon( QtGui.QIcon ( 'images/dirty.png' ) )
    self.setWindowTitle('dirty')
else:
    self.setWindowIcon( QtGui.QIcon ( 'images/clean.png' ) )
    self.setWindowTitle('clean')

Using the above, the WindowTitle changes perfectly and as expected, but the
icon remains stubbornly fixed as the MainWindow icon. 
I thought it might be stuggling with the QIcon, but I've checked the
isNull() and that's false.. so not Null.

As I test, I tried the changing the icon from the MainWindow object and that
works fine...

self.mdiArea.activeSubWindow().setWindowIcon(QtGui.QIcon
('images/dirty.png'))

So why is it ignoring me when i try it from the View?

Any Ideas?
Dan
