Calendar control GUI C++ library

Who knows a good component for 开发者_如何学运维a "calendar control" (NOT date/time picker)?

"Calendar control" means something like Mozilla Sunbird:

_{(source: mozilla.org)}

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);

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.

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.
