DPDisplayObjC()

Default constructor.
Creates invalid handle.

bool Draw(DPDisplayViewBodyC & canvas)

Draw object to canvas.

IndexRange2dC Frame() const

Find bounding box for object.

bool Query(const Vector2dC & pnt,StringC & text)

Query a point in the display.
Return true if point is within object.

const RCHandleC<DPDisplayObjBodyC> & operator =(const RCHandleC<DPDisplayObjBodyC> & oth)

Assign handle.

RCHandleC<DPDisplayObjBodyC> DeepCopy(UIntT levels = ((UIntT))) const

Do a deep copy of the object.

bool operator ==(const RCHandleC<DPDisplayObjBodyC> & oth) const

Are handles to the same object ?

bool operator !=(const RCHandleC<DPDisplayObjBodyC> & oth) const

Are handles to different objects ?

UIntT Hash() const

Default hash function.
This hashes on the address of the body.

bool IsValid() const

Test if this is a valid handle.

void Invalidate()

Invalidate this handle.
Unattaches the body from the handle.

bool IsHandleType(const DT &) const

Is handle of given type ?

void CheckHandleType(const DT & dummy) const

Check handle type. Throw an expception if not.

UIntT References() const

Find the number of references to the body of this object.

ostream & operator <<(ostream & strm,const RCHandleC<DPDisplayObjBodyC> & obj)

istream & operator >>(istream & strm,RCHandleC<DPDisplayObjBodyC> & obj)
