Detailed Description

Class that encapsulates an ActiveX so that it may be used as an IlvGraphic object.

Library: ilvcom

See also: IlvCOMGraphicFacade.; IlvGraphicAdapter.

Constructor & Destructor Documentation

◆ IlvGraphicCOMAdapter() [1/2]

IlvGraphicCOMAdapter::IlvGraphicCOMAdapter	(	IlvRect const &	bbox,
		char const *	identifier,
		IlvDisplay *	display
	)

Constructor.

This constructor initializes a graphic adapter object of an ActiveX, specified by an identifier.

Parameters

bbox	The bounding box of the graphic object.
identifier	The identifier of the control. This string can be a CLSID (with braces), a ProgID, a URL, or raw HTML (prefixed with `MSHTML:`). If either a URL or raw HTML is supplied, a Web browser will be loaded with this information.
display	The display instance.

◆ IlvGraphicCOMAdapter() [2/2]

IlvGraphicCOMAdapter::IlvGraphicCOMAdapter	(	IlvCOMGraphicFacade *	facade,
		IlvRect const &	bbox,
		IlBoolean	owner = `IlTrue`
	)

Constructor.

This constructor initializes a graphic adapter object from an IlvCOMGraphicFacade.

Parameters

facade	An `IlvCOMGraphicFacade` that encapsulates an ActiveX.
bbox	The bounding box of the graphic object.
owner	Specifies whether the current object must release the ActiveX (by the mean of a reference counter managed by the `IlvCOMGraphicFacade`) or not.

◆ ~IlvGraphicCOMAdapter()

virtual IlvGraphicCOMAdapter::~IlvGraphicCOMAdapter ( )

virtual

Destructor.

The destructor releases the resources used by this object. In particular, if the owner flag of the constructor was IlTrue, it decrements the reference counter associated to the ActiveX.

Member Function Documentation

◆ applyTransform()

virtual void IlvGraphicCOMAdapter::applyTransform ( IlvTransformer const * t )

virtual

Applies a transformation function to the graphic object.

Applies the transformer t to the shape of the object. Unless the transformation is a scaling operation, the result of applying it to certain objects can be insignificant. For example, applying a non-scaling transformer to an IlvRectangle object is meaningless, since the rectangle remains a rectangle. On the other hand, meaningful transformations can be applied to objects that are instances of types such as IlvLine or IlvPolyPoints.

Note: applyTransform() is one of the most important method to be rewritten for classes derived from IlvGraphic, since it is called by the resize(), move(), moveResize(), scale(), etc., methods.

Parameters

t	The transformer value. If `0`, no transformation is performed.

Implements IlvGraphic.

◆ applyValue()

virtual IlBoolean IlvGraphicCOMAdapter::applyValue ( const IlvValue & value )

virtual

Apply an accessor.

This member function is called by changeValue() and changeValues() methods.

It must not be called directly.

This method must be overriden by subclasses wishing to add a new accessor modifiable by changeValue().

Parameters

value The new value of the accessor.

Returns: IlTrue on success, otherwise IlFalse.

Reimplemented from IlvValueInterface.

◆ boundingBox()

virtual void IlvGraphicCOMAdapter::boundingBox	(	IlvRect &	bbox,
		IlvTransformer const *	t = `0`
	)		const

virtual

Retrieves the bounding box of the graphic object.

Sets bbox, the rectangle reference parameter, to be the bounding box of the object. Since the object can appear within a transformed environment (for example, in a multiview editor), an IlvTransformer object occurs as an optional parameter in order to compute the bounding box in the coordinate system of the transformed environment.

Parameters

bbox	The bounding box to be set.
t	A transformer value or `0` if there is no transformation.

Implements IlvGraphic.

◆ contains()

IlBoolean IlvGraphicCOMAdapter::contains	(	IlvPoint const &	p,
		IlvPoint const &	tp,
		IlvTransformer const *	t = `0`
	)		const

virtual

Checks whether a point is in the object.

Checks whether the coordinates are located in the shape of this object. A transformation parameter allows you to use the view's coordinate system for this test.

Parameters

p	The point to be tested.
tp	The transformed point obtained by applying the transformer t to the point p.
t	A transformer value, or `0` if there is no transformation.

Returns: IlTrue when the point p lies inside the outline of the object.

Reimplemented from IlvGraphic.

◆ draw()

virtual void IlvGraphicCOMAdapter::draw	(	IlvPort *	dst,
		IlvTransformer const *	t = `0`,
		IlvRegion const *	clip = `0`
	)		const

virtual

Draws the graphic object.

Draws the object in the given IlvPort using the transformer t.

Parameters

dst	The destination port this object is drawn onto.
t	The transformer value. If `0`, no transformation is performed.
clip	The clipping region, relative to the transformed object, or `0` if none.

Implements IlvGraphic.

◆ getAccessors()

virtual void IlvGraphicCOMAdapter::getAccessors	(	const IlSymbol const *	names,
		const IlvValueTypeClass const *	types,
		IlUInt &	count
	)		const

virtual

Retrieves the list of available accessors of an object.

Retrieves the list of accessors of an object. names is the resulting array of symbols. Each symbol is the name of an accessor. types is the array of the types of accessors, count is the number of accessors. The existing types for accessors are the following:

IlvValueBooleanType
IlvValueIntType
IlvValueUIntType
IlvValueFloatType
IlvValueDoubleType
IlvValueStringType
IlvValueDirectionType
IlvValueColorType
IlvValueFontType
IlvValuePatternType
IlvValueColorPatternType
IlvValueGradientPatternType
IlvValueLineStyleType
IlvValueFillStyleType
IlvValueFillRuleType
IlvValueArcModeType
IlvValueBitmapType
IlvValueStringArrayType
IlvValueUIntArrayType
IlvValueMenuItemArrayType
IlvValueMatrixItemArrayType
IlvValueNotebookPageArrayType

The possible accessors for an object are described in the corresponding class.

Parameters

names	The array of symbols returned by the method. Each symbol is the name of an accessor.
types	The array of types returned by the method. Each value is the type of an accessor.
count	The number of items in the arrays names and types.

Reimplemented from IlvGraphic.

◆ getDefaultInteractor()

char const* IlvGraphicCOMAdapter::getDefaultInteractor ( ) const

virtual

Gets the name of the default interactor for this object.

Returns: A string that identifies the object interactor that is likely to be associated with this graphic class. If it returns 0, then there is no default interactor for this graphic class.

Reimplemented from IlvGraphic.

◆ handleEvent()

virtual IlBoolean IlvGraphicCOMAdapter::handleEvent	(	IlvEvent &	event,
		IlvTransformer const *	t = `0`
	)		const

virtual

Handles mouse and keyboard events.

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

Parameters

event	The event to be handled.
t	The transformer.

Returns: IlTrue if the event is handled, IlFalse otherwise.

Implements IlvGraphicAdapter< IlvCOMGraphicFacade >.

◆ queryInterface()

HRESULT IlvGraphicCOMAdapter::queryInterface	(	REFIID	iid,
		void **	ppvObject
	)		const

Encapsulates IUnknown::QueryInterface

This method is a C++ replacement of the IUnknown::QueryInterface COM API, for the ActiveX associated with this view. See the COM API documentation for more information.

Parameters

iid	Identifier of the interface being requested.
ppvObject	The address of a pointer variable that receives the interface pointer requested in iid. Upon successful return, `ppvObject` contains the requested interface pointer to the object. If the object does not support the interface specified in iid, `ppvObject` is set to `NULL`.

Returns: S_OK if the interface is supported, and E_NOINTERFACE if it is not.

◆ queryValue()

virtual IlvValue& IlvGraphicCOMAdapter::queryValue ( IlvValue & val ) const

virtual

Retrieves an accessor value.

The queryValue() method can be used in the following way:

IlvValue arg("label");

char* label = (char*)labelObject->queryValue(arg);

This method must be overriden by subclasses wishing to add a new readable accessor.

Parameters

val	The `IlvValue` used both to identify the accessor and to store the return value.

Returns: A reference to val, which contains the resulting value.

See also: IlvValue.

Reimplemented from IlvValueInterface.

◆ setMode()

virtual void IlvGraphicCOMAdapter::setMode ( IlvDrawMode mode )

virtual

Sets the drawing mode of the object temporarily.

Changing the IlvDrawMode attribute of an object is considered a temporary operation. You have to set the mode to its default value when you no longer need another mode different from the value IlvModeSet. The drawing mode information is passed to the palette of the graphic object (see the IlvPalette::setOverwrite() method for more details).

Parameters

mode	The drawing mode to be set.

Reimplemented from IlvGraphic.

◆ setOverwrite()

virtual void IlvGraphicCOMAdapter::setOverwrite ( IlBoolean over )

virtual

Sets an overwrite mode that modifies how the drawing member functions operate.

Modifies the way the drawing member functions operate. The information is passed to the palette of the graphic object (see the IlvPalette::setOverwrite() method for more details).

Parameters

over	If `IlFalse`, sets selective hidden drawing operations.

Reimplemented from IlvGraphic.

◆ setPalette()

virtual void IlvGraphicCOMAdapter::setPalette ( IlvPalette * palette )

virtual

Sets the palette of the object.

Each of the graphic properties of this object is then taken from this IlvPalette instance.

Parameters

palette The palette to be set.

Reimplemented from IlvGraphic.

◆ writeAdaptee()

virtual void IlvGraphicCOMAdapter::writeAdaptee ( IlvOutputFile & os ) const

virtual

Saves the data specific to the adaptee.

Parameters

os	The `IlvOutputFile` that is written to.
