Detailed Description

This view element paints a dag. It uses the SDAGNodeViewEl and the SDAGEdgeViewEl classes for painting nodes and edges.

Member Enumeration Documentation

enum SDAGViewEl::DAGViewState

Internal state enum, important for graphical stuff like dragging, inserting etc. Enumeration values: Idle  InsertNode  DragNode  SelectEdgeStart  SelectEdgeEnd  DragEdge

enum SDAGViewEl::GraphType

Type of graph. Enumeration values: DIRECTED  UNDIRECTED

enum SDAGViewEl::HitTestInfo

Different possibilties for the mouse click. Enumeration values: GetHit  OnContext  OnNode  OnEdge

enum SDAGViewEl::MenuIDs

Enum for selecting menu entries. Enumeration values: COLOR_MENU_ID_WHITE  COLOR_MENU_ID_RED  COLOR_MENU_ID_BLUE  COLOR_MENU_ID_GREEN  COLOR_MENU_ID_YELLOW  COLOR_MENU_ID_USER  SHAPE_MENU_ID_ELLIPSE  SHAPE_MENU_ID_RECTANGLE  WIDTH_MENU_ID_1  WIDTH_MENU_ID_2  WIDTH_MENU_ID_3  WIDTH_MENU_ID_4  WIDTH_MENU_ID_5

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

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 & SDAGViewEl::getBoundBox (    )  [virtual]

calculate the bounding box Reimplemented from SViewEl.

QRegion SDAGViewEl::getRegion (    )  [virtual]

Get the region that is covered by the dag. 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.

bool SDAGViewEl::isAffectedBy (  QMouseEvent *    )  [virtual]

Checks if the dag is affected by the mouse event. Parameters: e  is the mouse event should be tested. Reimplemented from SViewEl.

bool SDAGViewEl::isDirected (    )

Checks if the graph is directed or not. Returns: TRUE if the graph is directed otherwise FALSE.

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

bool SDAGViewEl::load (    )  [slot]

Clears the dagview and create a new graph. It uses _ts->getPrecBroker().getDAG().getGraph().

bool SDAGViewEl::mouseEvent (  QMouseEvent *    e )  [virtual]

This is the central function for mouse events. It gets the event type and calls one of the mousePress, mouseRelease or mouseMove methods. Reimplemented from SViewEl.

void SDAGViewEl::numberOfEdges (  int    )  [signal]

Signal for notifying the parent, that the number of edges has changed. (for updating labels etc.).

void SDAGViewEl::numberOfNodes (  int    )  [signal]

Signal for notifying the parent, that the number of nodes has changed. (for updating labels etc.).

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

Calls the paint() functions of the children (nodes and edges). Implements SViewEl.

void SDAGViewEl::removeEdge (  SDAGEdgeViewEl *    edge )  [protected]

Removes a edge from the dag. Parameters: edge  is the edge that is to be removed.

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 SDAGViewEl::setPos (  QPoint    p )  [virtual]

Sets a new position for the dag. Parameters: p  is the new position of the dag. Reimplemented from SViewEl.

void SDAGViewEl::setView (  SView &    view )  [virtual]

Sets the view for this element and all of its children. Reimplemented from SViewEl.

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 SDAGViewEl::update (  const class SEvent &    )  [virtual]

Reacts on edit and pref events. Reimplemented from SViewEl.
