Constructor & Destructor Documentation

Symbol()

Symbol::Symbol ( SymbolType  symbolType, QGraphicsItem *  parent = 0  )

explicit

Constructs a Symbol with current symbol being symbol and parented to parent.

Here is the call graph for this function:

~Symbol()

Symbol::~Symbol ( )

virtual

Destructor.

Member Function Documentation

alignTo()

void Symbol::alignTo

(

const QLineF &

to

)

This method aligns *this* Symbol to the line being passed. That is, it ensures that the axis of this symbol aligns exactly with the "to" line passed.

Also this item is moved such that the second end point of the SymbolEndPoints for the current symbol *collides* with the second end point of "to" line.

Here is the call graph for this function:

boundingRect()

QRectF Symbol::boundingRect ( ) const

virtual

Returns

The bound rectangle for this based on current symbol.

brush()

QBrush Symbol::brush

(

)

const

Returns

The brush used to fill symbol.

paint()

void Symbol::paint ( QPainter *  painter, const QStyleOptionGraphicsItem *  option, QWidget *  widget  )

virtual

Draws the current symbol using the QPainterPath stored for the current symbol.

Here is the call graph for this function:

pen()

QPen Symbol::pen

(

)

const

Returns

The pen used to draw symbol.

setBrush()

void Symbol::setBrush

(

const QBrush &

brush

)

Sets the brush used to fill symbol.

Here is the call graph for this function:

setPen()

void Symbol::setPen

(

const QPen &

pen

)

Sets the pen used to draw the symbol.

Here is the call graph for this function:

setSymbolType()

void Symbol::setSymbolType

(

SymbolType

symbolType

)

Sets the current symbol type to symbol and updates the geometry.

Here is the call graph for this function:

setupSymbolTable()

void Symbol::setupSymbolTable ( )

staticprivate

shape()

QPainterPath Symbol::shape ( ) const

virtual

Returns

The path for this based on current symbol.

Here is the call graph for this function:

symbolEndPoints()

Symbol::SymbolEndPoints Symbol::symbolEndPoints

(

)

const

Returns

The end points for the symbol.

symbolType()

Symbol::SymbolType Symbol::symbolType

(

)

const

Returns

The current symbol being represented.

a table which stores all symbol properties

SymbolEndPoints: The first point is where the AssociationLine's visible line is supposed to end. The second points is where the actual symbol part is to appear.
