Detailed Description

template<class ADAPTEE>
class IlvGraphicAdapter< ADAPTEE >

Frame class to adapt any object as an IlvGraphic.

Library: views

This template class is intended to be used as a base class (it is a pure abstract class). The parameter of the template ADAPTEE specifies the type of the adpatee object.

Among the member functions inherited from IlvGraphic, the following ones have to be defined:

virtual void boundingBox(IlvRect& rect,
const IlvTransformer* t = 0) const
virtual IlBoolean contains(const IlvPoint& p,
const IlvPoint& tp,
const IlvTransformer* t = 0) const;
virtual void draw(IlvPort* dst,
const IlvTransformer* t = 0,
const IlvRegion* clip = 0) const;
virtual void applyTransform(const IlvTransformer* t);

The following member functions are likely to be redefined:

virtual void drawPalette(const IlvPalette* pal,
IlvPort* dst,
const IlvTransformer* t = 0,
const IlvRegion* clip = 0) const;
virtual void setBackground(IlvColor* c);
virtual void setForeground(IlvColor* c);
virtual void setFont(IlvFont* f);
virtual void setPattern(IlvPattern* p);
virtual void setMode(IlvDrawMode m);
virtual void setArcMode(IlvArcMode m);
virtual void setFillRule(IlvFillRule m);
virtual void setFillStyle(IlvFillStyle f);
virtual void setLineStyle(IlvLineStyle* style);
virtual void setLineWidth(IlUShort width);
virtual void setOverwrite(IlBoolean overwrite);
virtual void setAlpha(IlvIntensity alpha);
virtual IlBoolean zoomable() const;
virtual void setPalette(IlvPalette* pal);
virtual void print(ILVSTDPREF ostream&, int level = 0) const;

Constructor & Destructor Documentation

template<class ADAPTEE>
IlvGraphicAdapter< ADAPTEE >::IlvGraphicAdapter ( ADAPTEE *  obj,
IlBoolean  owner = IlFalse 
)

Constructor.

Initializes the data members specific to the class.

Parameters
objA pointer to an ADAPTEE (type given as parameter of the template) IlvGraphic. The type of the object is given as parameter to the template.
ownerAn IlBoolean. The default value is IlFalse, that means that the adaptee is not owned.
See also
IlvGraphicAdapter::~IlvGraphicAdapter()
IlvGraphicAdapter::isOwner()
IlvGraphicAdapter::getAdaptee()
IlvGraphicAdapter::setAdaptee()
template<class ADAPTEE >
IlvGraphicAdapter< ADAPTEE >::~IlvGraphicAdapter ( )
pure virtual

Destructor.

The adaptee is unlocked. If the reference counter is null and has the property owner set to true - that means at least one of the adapters that share this adaptee is owner - then the adaptee is deleted.

See also
IlvGraphicAdapter::IlvGraphicAdapter()
template<class ADAPTEE>
IlvGraphicAdapter< ADAPTEE >::IlvGraphicAdapter ( )
protected

Constructor.

This protected constructor may only be used by a derived class.

Member Function Documentation

template<class ADAPTEE>
virtual IlvReferenceStreamer* IlvGraphicAdapter< ADAPTEE >::factory ( ) const
protectedpure virtual

Creates an IlvReferenceStreamer.

The object returned by this function must be deleted.

Returns
The reference streamer for the adaptee.

Implemented in IlvGraphicCOMAdapter.

template<class ADAPTEE>
ADAPTEE* const IlvGraphicAdapter< ADAPTEE >::getAdaptee ( ) const

Returns a const pointer to the adaptee.

The type is given by the parameter of the template.

Returns
A const pointer to an ADAPTEE (type given as parameter of the template).
See also
IlvGraphicAdapter::setAdapter()
template<class ADAPTEE>
virtual IlBoolean IlvGraphicAdapter< ADAPTEE >::handleEvent ( IlvEvent event,
const IlvTransformer t = 0 
) const
pure virtual

Handles mouse and keyboard events.

The function returns IlFalse if the event has not been dealt with.

Parameters
eventThe event to be handled.
tThe transformer.
Returns
IlTrue if the event is handled, IlFalse otherwise.
template<class ADAPTEE>
IlBoolean IlvGraphicAdapter< ADAPTEE >::isOwner ( ) const

Returns the ownership property.

Returns
IlTrue when the object has the ownership of the adaptee, IlFalse otherwise.
See also
IlvGraphicAdapter::setAdaptee()
template<class ADAPTEE>
void IlvGraphicAdapter< ADAPTEE >::setAdaptee ( ADAPTEE *  adaptee,
IlBoolean  owner 
)

Sets the adpatee.

First, this function calls the virtual member function beforeSetAdaptee().

Second it calls the factory of IlvOwnership in order to get an owner object. The previous object, if any, is automatically unlocked through a reference counter mechanism.

Third, it calls the virtual member function afterSetAdaptee().

Parameters
adapteeA pointer to an ADAPTEE (type given as parameter of the template).
ownerAn IlBoolean that specifies the ownership of the adaptee.
See also
IlvGraphicAdapter::getAdaptee()
template<class ADAPTEE >
void IlvGraphicAdapter< ADAPTEE >::write ( IlvOutputFile os) const
pure virtual

Writes out the object description.

This member function uses a IlvReferenceStreamer to save the adaptee through a call to template<class OBJECT> void IlvWrite(IlvOwnership<OBJECT>&, IlvOutputFile&, IlvReferenceStreamer&).

The derived classes must save their data after having called this function.

Parameters
osThe IlvOutputFile that is written to.
See also
IlvGraphicAdapter::writeAdaptee()
IlvWrite()

Implements IlvGraphic.

template<class ADAPTEE>
virtual void IlvGraphicAdapter< ADAPTEE >::writeAdaptee ( IlvOutputFile os) const
protectedpure virtual

Saves the data specific to the adaptee.

Parameters
osThe IlvOutputFile that is written to.

Implemented in IlvGraphicCOMAdapter.
