User Level:Normal
In Scope:RavlGUIN

Parent Classes: Methods:
DPDisplayImageRealC(const ImageC<RealT> & img)
Construct from an image.

Default constructor.
creates an invalid handle.

#include "Ravl/GUI/DPDisplayObj.hh"
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.

#include "Ravl/RefCounter.hh"
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)
