Custom widget inside the 'boxes' of a Calendar

[Sytematic]

So I have a Calendar with the typical boxes representing the events. What I want is, to be able to draw any widget inside the box. Is this possible?

Ie., anything inheriting from Canvas.

I think it is possible, but reading the API i am not so sure where to start/ what to override.

Any hints would be nice!

Is it possible?

I have the same problem and my solution was fill the box with html content. Is necessary override the method getDayBodyHTML and return the html.
