Reuse calendar applet

[Flavio Castelli]

I'm trying to reuse the plasma calendar applet inside my application.

Currently I've been able to embed the applet but  I have not been able to 
handle the date selection events.

This signal is emitted by the Plasma::Calendar class defined by 
kdebase/workspace/libs/plasmaclock/calendar.h.
There's an instance of Plasma::Calendar inside of CalendarApplet which is 
accessible by the CalendarApplet::graphicsWidget().

The CalendarApplet class is declared inside of 
kdebase/workspace/plasma/generic/applets/calendar/calendar.h but this file is 
not installed.

Am I missing something?

Thanks in advance
Flavio
