KODayMatrix Class Reference

List of all members.


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

Constructor & Destructor Documentation

KODayMatrix::KODayMatrix ( QWidget *  parent,
const char *  name 
)

constructor to create a day matrix widget.

Parameters:
parent widget that is the parent of the day matrix. Normally this should be a KDateNavigator
name name of the widget

Definition at line 101 of file kodaymatrix.cpp.

KODayMatrix::~KODayMatrix (  ) 

destructor that deallocates all dynamically allocated private members.

Definition at line 139 of file kodaymatrix.cpp.


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.

Definition at line 116 of file kodaymatrix.cpp.

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.

Definition at line 216 of file kodaymatrix.cpp.

void KODayMatrix::updateEvents (  ) 

Update event states of dates.

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

Definition at line 270 of file kodaymatrix.cpp.

const QDate & KODayMatrix::getDate ( int  offset  ) 

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

Definition at line 293 of file kodaymatrix.cpp.

QString KODayMatrix::getHolidayLabel ( int  offset  ) 

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

Definition at line 302 of file kodaymatrix.cpp.

void KODayMatrix::addSelectedDaysTo ( DateList &   ) 

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

Definition at line 147 of file kodaymatrix.cpp.

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. (?)

Definition at line 180 of file kodaymatrix.cpp.

void KODayMatrix::clearSelection (  ) 

Clear all selections.

Definition at line 188 of file kodaymatrix.cpp.

bool KODayMatrix::isTodayVisible (  )  const [inline]

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

Definition at line 170 of file kodaymatrix.h.

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).

Definition at line 178 of file kodaymatrix.h.

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).

Definition at line 211 of file kodaymatrix.cpp.

void KODayMatrix::recalculateToday (  )  [slot]

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

Definition at line 193 of file kodaymatrix.cpp.

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
