What d_ptr and q_ptr stand for?

[gilgil]

What d_ptr and q_ptr stand for exactly those can be found in many other qt source files(e.g. qobject.cpp)?

Hi!

These are pointers used to implement the "Pimpl idiom" (= pointer to implementation idiom). See "Wikipedia":http://en.wikipedia.org/wiki/Opaque_pointer

Cheers!
