Detailed Description

This is the base class for small building blocks which can be combined to a graphical display. This can be single machines, jobs, etc. View elements do only paint themselves. They are not responsible for setting up the graphical context and for communicating with the window system.

Member Enumeration Documentation

enum SViewEl::SMarkStyles

Mark styles influence the style how the ViewEl is displayed. The styles are stored in SVis...-objects. Identical mark styles should produce similar (NOT HARDCODED) effects in different ViewEls. Enumeration values: STANDARD  MARKED  MARKED1  MARKED2  MARKED3  MARKED4

Constructor & Destructor Documentation

SViewEl::SViewEl (    )  [inline]

Constructs a new SViewEl. It initializes the pointer to the tasksystem. The corresponding view is set by the public member setView( SView &view ). ts SHOULD BE TAKEN OUT OF HERE EVENTUALLY! (AH)

SViewEl::SViewEl (  STaskSystem *    ts )  [inline]

Member Function Documentation

void SViewEl::draw3DRect (  QPainter &    p, const QRect &    r )  [inline, protected]

void SViewEl::draw3DRect (  QPainter &    p, int    x, int    y, int    w, int    h )  [protected]

paint a 3D Rectangle use current Brush as color

virtual const QRect& SViewEl::getBoundBox (    )  const [inline, virtual]

Reimplemented in SDAGEdgeViewEl, SDAGNodeViewEl, and SDAGViewEl.

virtual QRegion SViewEl::getRegion (    )  [pure virtual]

Returns: the region which is covered by this view element. DEPRECATED (AH): use getBoundBox() instead Implemented in SDAGEdgeViewEl, SDAGNodeViewEl, SDAGViewEl, and SMeshTopViewEl.

SView& SViewEl::getView (    )  [inline, protected]

Get the view which is responsible for this view element. This is useful for setting new cursors etc. . Returns: the view for this view element.

virtual bool SViewEl::isAffectedBy (  QMouseEvent *    ev )  [inline, virtual]

The isAffectedBy function checks if an element is affected by a particular mouse event. Parameters: ev  the mouse event we are talking about. Returns: true if event is handled directly by this object (in particular not only by a child). Reimplemented in SDAGViewEl.

QColor SViewEl::lighterGray (    )  [inline, protected]

virtual bool SViewEl::mouseEvent (  QMouseEvent *    ev )  [inline, virtual]

This virtual function handles the mouse event. You can feed it with the captured mouse event from your view. Returns: true if the mouse event was handled succesfully. Reimplemented in SDAGViewEl.

virtual void SViewEl::paint (  QPaintDevice *    pd, QRect    rect )  [pure virtual]

The paint function paints the element in the paintdevice. Parameters: pd  This is the paintdevice the element is painted in. Normally paintDev comes from the _pView, but it might also be printer or almost anything else. rect  This QRect is the area where the painting takes place. Implemented in SDAGEdgeViewEl, SDAGNodeViewEl, SDAGViewEl, and SMeshTopViewEl.

void SViewEl::requestRepaint (  const QRect &    rect )  [inline, protected]

void SViewEl::requestRepaint (    )  [inline, protected]

If something in the view element has changed and you want to make the changes visible, then request a repaint for the view element. CAUTION: repaints everything!

virtual void SViewEl::setPos (  QPoint    p )  [inline, virtual]

Here you can set the position of the view element. Parameters: p  the new position of the view element. Reimplemented in SDAGNodeViewEl, and SDAGViewEl.

virtual void SViewEl::setView (  SView &    view )  [inline, virtual]

Set the view which accepts the repaint-requests. Parameters: view  This paramter is a reference to the parent view ( the view which accepts the repaint-requests. Reimplemented in SDAGViewEl.

virtual void SObserver::update (  const SEvent &    event )  [pure virtual, inherited]

Here the class is informed of an event, when an observed component has sent an event by SObservable::notifyObservers() Parameters: event  event sent by an observed component (the reference is not guaranteed to be valid after the termination of the call to update() See also: SObservable::notifyObservers() Implemented in SGanttLog, SLogger, SJobArray, and STaskSystem.

virtual void SViewEl::update (  const class SEvent &    )  [inline, protected, virtual]

This update function gets the project specific events for updating the view element. Reimplemented in SDAGNodeViewEl, SDAGViewEl, and SMeshTopViewEl.
