/**
* replacement for kdpdatebuton.cpp that used 42 widgets for the day matrix to be displayed.
* Cornelius thought this was a waste of memory and a lot of overhead.
* In addition the selection was not very intuitive so I decided to rewrite it using a QFrame
* that draws the labels and allows for dragging selection while maintaining nearly full
* compatibility in behaviour with its predecessor.
*
* The following functionality has been changed:
*
* o when shifting events in the agenda view from one day to another the day matrix is updated now
* o TODO ET dragging an event to the matrix will MOVE not COPY the event to the new date.
* o no support for Ctrl+click to create groups of dates
* (This has not really been supported in the predecessor. It was not very intuitive nor was it
* user friendly.)
* This feature has been replaced with dragging a selection on the matrix. The matrix will
* automatically choose the appropriate selection (e.g. you are not any longer able to select
* two distinct groups of date selections as in the old class)
* o now that you can select more then a week it can happen that not all selected days are
* displayed in the matrix. However this is preferred to the alternative which would mean to
* adjust the selection and leave some days undisplayed while scrolling through the months
