I see, I'll take a look. It is probably not necessary to call getIcon at 
all.

Frankly, I am not at ease at all with the way things get updated. I do 
not understand the Qt mechanisms well enough. If you feel like trying to 
understand it, please do. Be warn though that we are in a working but 
fragile situation now, changes will lead to a rough ride but it is 
probably worth the cost.
