Member Function Documentation

void addArc ( const CRect rect,
double  startAngle,
double  endAngle,
bool  clockwise 
)
virtual

add an arc to the path.

Begins a new subpath if no elements were added before.

void addBezierCurve ( const CPoint control1,
const CPoint control2,
const CPoint end 
)
virtual

add a bezier curve to the path.

A subpath must begin before

void addBezierCurve ( CCoord  cp1x,
CCoord  cp1y,
CCoord  cp2x,
CCoord  cp2y,
CCoord  x,
CCoord  y 
)
inline
void addEllipse ( const CRect rect)
virtual

add an ellipse to the path.

Begins a new subpath if no elements were added before.

void addLine ( const CPoint to)
virtual

add a line to the path.

A subpath must begin before

void addLine ( CCoord  x,
CCoord  y 
)
inline
void addPath ( const CGraphicsPath path,
CGraphicsTransform transformation = 0 
)
virtual

add another path to the path.

Begins a new subpath if no elements were added before.

void addRect ( const CRect rect)
virtual

add a rectangle to the path.

Begins a new subpath if no elements were added before.

void addRoundRect ( const CRect size,
CCoord  radius 
)
void beginSubpath ( const CPoint start)
virtual

begin a new subpath.

void beginSubpath ( CCoord  x,
CCoord  y 
)
inline
void closeSubpath ( )
virtual

close a subpath.

A straight line will be added from the current point to the start point.

virtual CGradient* createGradient ( double  color1Start,
double  color2Start,
const CColor color1,
const CColor color2 
)
pure virtual

creates a new gradient object, you must release it with forget() when you're done with it

Parameters
color1Startvalue between zero and one which defines the normalized start offset for color1
color2Startvalue between zero and one which defines the normalized start offset for color2
color1the first color of the gradient
color2the second color of the gradient
Returns
a new gradient object
