Hello,
Maybe you can use a derived class, in python this would look like:
QIconWithPath(QIcon):
def __init__(self,iconPath):
super(QIconWithPath,self).__init__(iconPath)
self.setIconPath(iconPath)
I'm not sure this is considered elegant...

Hi All,
I'd like to add a "Set Group Icon..." action to the context menu for
groups in the layer tree. I'm preparing a pull request for that.
Everything is working fine, but I have a doubt on how to make the QGIS
project to store the QIcon (location), so that when the project is
open again, the QIcon can be constructed properly.
My first attempt was to store the QIcon path in the project, which
works fine when the icon is set through QGIS GUI. However, it wouldn't
work for PyQGIS users, who pass a QIcon object to the setIcon() method
of QgsLayerTreeGroup. Since QIcon does not store its image file path,
it would not be possible to access the path and store it in the
project file. I would have to force PyQGIS users to set the image file
path via get/set functions iconPath()-setIconPath(), which is not very
elegant, but it's the only solution I see.
Do you know any other solution for this problem? Perhaps something
about storing the QIcon somehow serialized?
Regards,
Germán Carrillo
