Calendar control GUI C++ library

Question

Who knows a good component for a "calendar control" (NOT date/time picker)?
"Calendar control" means something like Mozilla Sunbird:

Requirements to the control:
- C++;
- Day/Week/Month view;
- Support of several calendars;
- Without MFC dependences;

Nice to have:
- Open source;
- Cross plathform;
- Free;
- Minimum external dependences (boost etc are fine);

Answer 1

You are unlikely to find such a control ready made.
Even more unlikely to find one for C++ without MFC dependencies.

Your best bet is to implement it yourself.

Answer 2

The Qt Framework has an example calendar that you can use as a starting point, although it is nowhere near as complete as what you are looking for. No sensible GUI framework will have such a widget out-of-the-box.
