Detailed Description

This view element paints a node. You can use a QPixmap file for the nodes or drawed nodes ( ellipse or rectangle shape ). Some job information are displayed in the middle of the nodes.

Member Enumeration Documentation

enum SViewEl::SMarkStyles [inherited]

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

SDAGNodeViewEl::SDAGNodeViewEl (  STaskSystem *    ts, SJob &    job )

Constructs a new SDAGNodeViewEl. Parameters: job  is the SJob that is represented by this node.

SDAGNodeViewEl::~SDAGNodeViewEl (    )

Member Function Documentation

void SDAGNodeViewEl::addEdge (  SDAGEdgeViewEl *    edge )  [inline]

Function for adding a edge to the list of adjacent edges of this node. These edges are repositioned by the node if you call moveTo(..).

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

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

paint a 3D Rectangle use current Brush as color

const QRect & SDAGNodeViewEl::fullBoundBox (    )

calculate bounding box with edges

const QRect & SDAGNodeViewEl::getBoundBox (    )  [virtual]

calculate the bounding box Reimplemented from SViewEl.

int SDAGNodeViewEl::getHeight (    )  [inline]

Returns: the height of the node.

SJob& SDAGNodeViewEl::getJob (    )  [inline]

Returns: the SJob which is represented by this node.

QPoint SDAGNodeViewEl::getPos (    )  [inline]

Returns: the position of the node on the paintdevice in a qpoint. The returned position is the middle of the node.

QRegion SDAGNodeViewEl::getRegion (    )  [inline, virtual]

Returns: the region which is covered by the node. Implements SViewEl.

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

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.

int SDAGNodeViewEl::getWidth (    )  [inline]

Returns: the width of the node.

void SDAGNodeViewEl::hide (    )  [inline]

Hides this node. Sets _visible to FALSE, so that this node isn't repainted until _visible is set to TRUE (show() !) again.

void SDAGNodeViewEl::initPixmap (    )

Initializes the _pixmap.

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

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.

bool SDAGNodeViewEl::isVisible (    )  [inline]

Tests if this node is visible or not. Returns: TRUE if the node is visible, or FALSE if not.

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

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

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.

void SDAGNodeViewEl::moveTo (  QPoint    pos )  [inline]

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

void SDAGNodeViewEl::moveTo (  int    x, int    y )

Moves the node to a new position. If the node has adjacent edges they will be repositioned. Parameters: x  is the x-coordinate of the new position. y  is the y-coordinate of the new position.

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

Paints the node to the paintdevice. Parameters: pd  is the paintdevice for the painting action. rect  is the painting/clipping rect. Implements SViewEl.

void SDAGNodeViewEl::removeEdge (  SDAGEdgeViewEl *    edge )  [inline]

Removes an edge from the list '_edges' of the node.

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

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

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!

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

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Reimplemented from SViewEl.

void SDAGNodeViewEl::setPos (  int    x, int    y )

Positions a node without repositioning its adjacent edges.

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

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.

void SDAGNodeViewEl::show (    )  [inline]

Shows this node: Sets _visible to TRUE, so that this node is repainted.

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.

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

This view element reacts on scheduling events. Reimplemented from SViewEl.
