Sam Truscott 5dc13f3538 Tidy up the code for cppcheck style. 2014-03-13 16:47:00 +00:00
Sam Truscott 3d0524ecc6 Update the detection of the arguments in Qt's invokeMethod.
invokeMethod can invoke functions by name (string) rather than a
direct function call (i.e. reflection). The old code wasn't
correctly parsing out the argument which contained the name
of the function to call.

This resulted in that function being reported as unused when it is.
