Qt namespace flags: hexadecimal versus decimal

[neuronet]

If you look at the Qt namespace:
http://qt-project.org/doc/qt-4.8/qt.html#details

Some flag enumerations depict the flags as hexadecimals (e.g., dropActions), while others are represented in decimal notation (e.g., itemFlags). Is this a substantive difference, or an arbitrary difference in convention of how they are enumerated?

I work in PyQt/PySide and it seems there is no difference.

There is no difference.

The enums given as hexadecimal are typically intended to be used as flags in combination and the hex representation makes the bits involved more obvious. Ultimately though a number is just a number.
