  *  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
