Suspicious calculation. Please use parentheses to clarify the code. The code ''a&b?c:d'' should be written as either ''(a&b)?c:d'' or ''a&(b?c:d)''.

Class 'DBounceAnimationPrivate' has a constructor with 1 argument that is not explicit. Such constructors should in general be explicit for type safety reasons. Using the explicit keyword in the constructor means some mistakes when using the class can be avoided.

Class 'DIndeterminateProgressbarPrivate' has a constructor with 1 argument that is not explicit. Such constructors should in general be explicit for type safety reasons. Using the explicit keyword in the constructor means some mistakes when using the class can be avoided.

The class 'DIndeterminateProgressbarPrivate' is unsafe, wrong usage can cause memory/resource leaks for 'DIndeterminateProgressbarPrivate::m_animation'. This can for instance be fixed by adding proper cleanup in the destructor.
