[Interest] How to get icon theme?

[Matthew Woehlke]

How do I determine what icon theme my application is using? 
QIcon::themeName() just returns an empty string. (But 
QIcon::fallbackThemeName() says "breeze"!) I am actually using 
"breeze-dark", and if I don't do anything, I get icons from that theme.

I need to know because my application will use its own theme in order to 
provide additional icons and a consistent look within the application, 
so I need to be able to kick the system theme down to the fallback 
theme. (If I leave it as "breeze", I get illegible icons due to my color 
theme.)
