No, a method named HelpBrowser.loadResource() is called. 

Btw, you are covering a few python keywords in your code (type, help). 

It's usually a good practice to call parent methods with super (will 
save you from editing every method invocation, if you rebase your 
class one day, which usually results in _nasty_ behavior), and you 
and your typing fingers _really_ want to use PyQt's new style signals,
I sure.
