Detailed Description

Replacement for kdpdatebuton.cpp that used 42 widgets for the day matrix to be displayed. day matrix widget of the KDateNavigator.

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 behavior 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 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

const char *  name
 

constructor to create a day matrix widget.

Parameters:

name name of the widget

KODayMatrix::~KODayMatrix  ) 
 

destructor that deallocates all dynamically allocated private members.


Member Function Documentation

void KODayMatrix::setCalendar Calendar *   ) 
 

Associate a calendar with this day matrix.

If there is a calendar, the day matrix will accept drops and days with events will be highlighted.

void KODayMatrix::updateView const QDate &  actdate  ) 
 

updates the day matrix to start with the given date.

Does all the necessary checks for holidays or events on a day and stores them for display later on. Does NOT update the view visually. Call repaint() for this.

Parameters:
actdate recalculates the day matrix to show NUMDAYS starting from this date.

void KODayMatrix::updateEvents  ) 
 

Update event states of dates.

Depending of the preferences days with events are highlighted in some way.

const QDate & KODayMatrix::getDate int  offset  ) 
 

returns the QDate object associated with day indexed by the supplied offset.

QString KODayMatrix::getHolidayLabel int  offset  ) 
 

returns the official name of this holy day or 0 if there is no label for this day.

void KODayMatrix::addSelectedDaysTo DateList &   ) 
 

adds all actual selected days from mSelStart to mSelEnd to the supplied DateList.

void KODayMatrix::setSelectedDaysFrom const QDate &  start,
const QDate &  end
 

sets the actual to be displayed selection in the day matrix starting from start and ending with end.

Theview must be manually updated by calling repaint. (?)

void KODayMatrix::clearSelection  ) 
 

Clear all selections.

bool KODayMatrix::isTodayVisible  )  const [inline]
 

Is today visible in the view? Keep this in sync with the values today (below) can take.

bool KODayMatrix::isBeginningOfMonth  )  const [inline]
 

If today is visible, then we can find out if today is near the beginning or the end of the month.

This is dependent on today remaining the index in the array of visible dates and going from top left (0) to bottom right (41).

void KODayMatrix::updateView  )  [slot]
 

Recalculates all the flags of the days in the matrix like holidays or events on a day (Actually calls above method with the actual startdate).

void KODayMatrix::recalculateToday  )  [slot]
 

Calculate which square in the matrix should be hilighted to indicate it's today.

void KODayMatrix::selected const KCal::DateList &  daylist  )  [signal]
 

emitted if the user selects a block of days with the mouse by dragging a rectangle inside the matrix

Parameters:
daylist list of days that have been selected by the user

void KODayMatrix::incidenceDropped Incidence *  incidence,
const QDate &  dt
[signal]
 

emitted if the user has dropped an incidence (event or todo) inside the matrix

Parameters:
incidence the dropped calendar incidence
dt QDate that has been selected

void KODayMatrix::incidenceDroppedMove Incidence *  oldincidence,
const QDate &  dt
[signal]
 

emitted if the user has dropped an event inside the matrix and chose to move it instead of copy

Parameters:
oldincidence the new calendar incidence
dt QDate that has been selected
