Public Member Functions | |
Arc (const Coordinate ¢er, const double radius, const double startangle, const double angle) | |
Construct an Arc with a given center, radius, start angle and dimension (both in radians). | |
Arc * | copy () const |
Returns a copy of this Object. | |
Object * | transform (const Transformation &t) const |
Return this Object, transformed by the transformation t. | |
bool | valid () const |
Returns true if this is a valid Object. | |
const ObjectType * | type () const |
Returns the lowermost ObjectType that this object is an instantiation of. | |
const Coordinate | center () const |
Return the center of this arc. | |
double | radius () const |
Return the radius of this arc. | |
double | startAngle () const |
Return the start angle in radians of this arc. | |
double | angle () const |
Return the dimension in radians of this arc. | |
Coordinate | firstEndPoint () const |
Return the start point of this arc. | |
Coordinate | secondEndPoint () const |
Return the end point of this arc. | |
const double | sectorSurface () const |
Return the size of the sector surface of this arc. | |
bool | equals (const Object &rhs) const |
Returns true if this Object is equal to rhs. | |
bool | containsPoint (const Coordinate &p, const KigDocument &doc) const |
Return whether this Curve contains the given point. | |
Static Public Member Functions | |
static const ObjectType * | stype () |
Returns the ObjectType representing the Arc type. |
Detailed Description

static const ObjectType* Arc::stype | ( | ) | [static] |
Arc* Arc::copy | ( | ) | const [virtual] |
bool Arc::valid | ( | ) | const |
Returns true if this is a valid Object.
If you want to return an invalid Object, you should return an InvalidObject instance.
Reimplemented from Object.
const ObjectType* Arc::type | ( | ) | const [virtual] |
Returns the lowermost ObjectType that this object is an instantiation of.
E.g. if you want to get a string containing the internal name of the type of an object, you can do:
tn = object.type().internalName()
Implements Object.
