Detailed Description

Graphic class.

Library: views

An IlvGraphicSet object organizes a set of IlvGraphic objects. IlvGraphicSet implements all geometric and graphic member functions by means of calls to the member functions of the objects that it contains. For example, the draw() method of IlvGraphicSet calls the draw method of the objects contained in the graphic set.

- IlvGraphicSet -

See also: IlvManager::group(), IlvManager::unGroup().

Accessors\nAccessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods <tt>IlvValueInterface::queryValue()</tt>, <tt>IlvValueInterface::queryValues()</tt>, <tt>IlvValueInterface::changeValue()</tt>, <tt>IlvValueInterface::changeValues()</tt>.\n\n\nThis class inherits the accessors of its superclass \c IlvGraphic and adds the following ones:

Data accessors

Name	Type	Equivalent methods
`cardinal`	UInt	`getCardinal()`

Method accessors

Name	Return type	Equivalent methods
`getObjectAt(UInt index)`	Object	`getObject(IlUInt index) const`

Constructor & Destructor Documentation

◆ IlvGraphicSet() [1/2]

IlvGraphicSet::IlvGraphicSet ( )

Initializes an empty IlvGraphicSet object.

The new IlvGraphicSet object becomes is a skeleton. You can call member functions such as addObject() to add IlvGraphic objects to the IlvGraphicSet object.

◆ IlvGraphicSet() [2/2]

IlvGraphicSet::IlvGraphicSet	(	int	num,
			...
	)

Initializes an IlvGraphicSet object that groups a set of IlvGraphic objects.

The IlvGraphic objects are provided as the parameters following num.

Parameters

num	The number of initial objects in this new graphic set. This should also be the number of parameters that follow num, and all must be pointers to valid instances of `IlvGraphic`.

◆ ~IlvGraphicSet()

IlvGraphicSet::~IlvGraphicSet ( )

Destructor.

The destructor destroys all the objects that are stored in this graphic set.

Member Function Documentation

◆ addObject()

virtual void IlvGraphicSet::addObject ( IlvGraphic * obj )

virtual

Adds an object.

Adds an object at the end of the objects list, so it will be the last to be drawn.

Note: Although it is possible to add an object twice to the object list, it is not recommended.

◆ align()

void IlvGraphicSet::align ( IlvPosition align = IlvLeft )

Aligns the objects.

Applies an alignment to all objects, relatively to the global bounding box of the graphic set.

Parameters

align The direction of the alignment. This can be either IlvLeft, IlvTop, IlvRight, or IlvBottom to translate all the objects so that they share the indicated side coordinate. This parameter can also be set to IlvHorizontalCenter, IlvVerticalCenter, or IlvCenter to align the indicated positions.

◆ apply()

virtual void IlvGraphicSet::apply	(	IlvApplyObject	function,
		IlAny	arg
	)

virtual

Applies a function to the objects.

Applies a function to all the IlvGraphic objects that are referenced. The function function will be called for each object stored in this set. The function will receive, in turn, a pointer to each of the objects that are stored in the set and a user-defined parameter.

Parameters

function	The function to be applied to the objects.
arg	The user argument that will be provided to function for each object.

Reimplemented from IlvGraphic.

◆ applyReferences()

virtual void IlvGraphicSet::applyReferences	(	IlvApplyObject	function,
		IlAny	arg
	)

virtual

Applies a function to the referenced objects.

Calls the member function IlvGraphic::applyReferences() with the arguments function and argument for each object stored in the set.

Parameters

function	The function to be applied to the referenced objects.
arg	The user argument that will be provided to function for each object.

Reimplemented from IlvGraphic.

◆ applyTransform()

virtual void IlvGraphicSet::applyTransform ( const IlvTransformer * 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.

◆ boundingBox()

virtual void IlvGraphicSet::boundingBox	(	IlvRect &	bbox,
		const IlvTransformer *	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.

◆ column()

void IlvGraphicSet::column ( IlvDeltaPos spacing = 4 )

Force a vertical space between the objects.

Moves the objects vertically to set a constant vertical space between them. The method does not align the objects.

Parameters

spacing The vertical space that is set between two consecutive objects.

◆ contains()

virtual IlBoolean IlvGraphicSet::contains	(	const IlvPoint &	p,
		const IlvPoint &	tp,
		const IlvTransformer *	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 IlvGraphicSet::draw	(	IlvPort *	dst,
		const IlvTransformer *	t = `0`,
		const IlvRegion *	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.

◆ firstContains()

IlvGraphic* IlvGraphicSet::firstContains	(	const IlvPoint &	p,
		const IlvPoint &	tp,
		const IlvTransformer *	t = `0`
	)		const

Gets an object at a given location.

Parameters

p	The point, in the graphic set coordinates system that is looked at.
tp	The point, in the coordinates system defined by t that is looked at.
t	The transformation that is used for the seek.

Returns: A pointer to the first object located at p, or 0 if there are none. The tp parameter is the transformed point obtained by applying the transformer t to the point p. This allows you to use the view coordinates system for this test.

◆ firstIntersects()

IlvGraphic* IlvGraphicSet::firstIntersects	(	const IlvRegion &	region,
		const IlvTransformer *	t = `0`
	)		const

Gets an object in a given region.

Parameters

region	The region where objects are searched. This region is in the coordinates system defined by t.
t	The transformer.

Returns: A pointer to the first object that intersects with the region region, or 0 if there are none.

Returns: An array of graphic objects stored in this GraphicSet. This array will have count elements, and must not be modified or deleted. Other Rogue Wave Views functions can overwrite this array so the caller of this method should consider copying it.

◆ insertObject()

virtual void IlvGraphicSet::insertObject ( IlvGraphic * object )

virtual

Inserts an object.

Inserts an object at the beginning of the maintained list so it will be the first object to be drawn when the IlvGraphicSet object is redrawn.

Parameters

object The object to be inserted.

Reimplemented in IlvSelector.

◆ inside()

virtual IlBoolean IlvGraphicSet::inside	(	const IlvRegion &	r,
		const IlvTransformer *	t = `0`
	)		const

virtual

Determines whether an object with transformation applied is inside the bounding box.

Parameters

r	The region to be tested.
t	A transformer value, or `0` if there is no transformation.

Returns: IlTrue when the object, drawn with the transformer t, covers completely the region r. This member function returns IlFalse when this is not the case. That means that it returns IlTrue if all rectangles that define the region completely lie inside the object.

Reimplemented from IlvGraphic.

◆ intersects()

virtual IlBoolean IlvGraphicSet::intersects	(	const IlvRegion &	r,
		const IlvTransformer *	t = `0`
	)		const

virtual

Checks whether a region intersects the bounding box with transformation applied.

Parameters

r	The region to be tested.
t	A transformer value, or `0` if there is no transformation.

Returns: IlTrue when the region r overlaps the transformed object (if t is not 0) and IlFalse when this is not the case.

Reimplemented from IlvGraphic.

◆ invert()

virtual void IlvGraphicSet::invert ( IlBoolean temp = IlFalse )

virtual

Highlights the object.

Highlights the object. It is implemented as swapping the foreground and background colors of the object, but can have other implementations in derived subclasses. The parameter temp controls the way you toggle between the background and the foreground. If temp is omitted or is IlFalse, then a new palette is computed by calling the IlvDisplay::getPalette() method. If temp is IlTrue, the object palette is inverted, and thus all the objects referencing this palette will be affected.

Parameters

temp	If `IlTrue`, highlights the object.

Reimplemented from IlvGraphic.

◆ removeObject()

virtual void IlvGraphicSet::removeObject ( IlvGraphic * object )

virtual

Removes an object.

Removes an object from the list of referenced objects. If an object is stored more than once in the same IlvGraphicSet, only the first occurrence will be removed. The object is not destroyed.

Parameters

object The object to be removed from this graphic set.

Reimplemented in IlvSelector.

◆ row()

void IlvGraphicSet::row ( IlvDeltaPos spacing = 4 )

◆ sameHeight()

void IlvGraphicSet::sameHeight ( IlvDim height )

Force the height of all the objects.

Resizes each object according to a given height.

Parameters

height The new height of all the stored objects.

◆ sameWidth()

void IlvGraphicSet::sameWidth ( IlvDim width )

◆ setFillStyle()

virtual void IlvGraphicSet::setFillStyle ( IlvFillStyle style )

virtual

Sets the fill style of the object.

Parameters

style The new fill style.

Reimplemented from IlvGraphic.

◆ setFont()

virtual void IlvGraphicSet::setFont ( IlvFont * font )

virtual

Sets the font of the object.

Parameters

font	The new font.

Reimplemented from IlvGraphic.

◆ setForeground()

virtual void IlvGraphicSet::setForeground ( IlvColor * foreground )

virtual

Sets the foreground color of the object.

Parameters

foreground The new foreground color.

◆ setGradientPattern()

virtual void IlvGraphicSet::setGradientPattern ( IlvGradientPattern * pattern )

virtual

Sets the gradient pattern of the object.

Parameters

pattern The new gradient pattern.

◆ setHolder()

virtual void IlvGraphicSet::setHolder ( IlvGraphicHolder * )

virtual

Sets the object's holder.

Reimplemented from IlvGraphic.

◆ setLineStyle()

virtual void IlvGraphicSet::setLineStyle ( IlvLineStyle * style )

virtual

Sets the line style of the object.

Parameters

style The new line style.

Reimplemented from IlvGraphic.

◆ setLineWidth()

virtual void IlvGraphicSet::setLineWidth ( IlUShort width )

virtual

Sets the line width of the object.

Parameters

width The new line width.

Reimplemented from IlvGraphic.

◆ setMode()

virtual void IlvGraphicSet::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.

◆ setObject()

void IlvGraphicSet::setObject	(	IlUInt	index,
		IlvGraphic *	object
	)

Sets an object.

Changes the index ^th object of this set so it becomes object. If index is invalid, this function does nothing. The previous object is destroyed.

Parameters

index	The index of the object that is replaced.
object	The new object that is stored.

◆ setOverwrite()

virtual void IlvGraphicSet::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 IlvGraphicSet::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.

◆ setPattern()

virtual void IlvGraphicSet::setPattern ( IlvPattern * pattern )

virtual

Sets the pattern of the object.

Parameters

pattern The new pattern.

Reimplemented from IlvGraphic.

◆ symmetry()

virtual void IlvGraphicSet::symmetry ( IlvDirection axis )

virtual

Flips a graphic object.

Flips the object about one of the horizontal or vertical axis (or a combination of the two). The axis is given by the axis parameter, which you can give the value IlvHorizontal, in which case the flip takes place around the horizontal axis of the object, or IlvVertical, which flips the object around the vertical axis. You can also use the IlvCenter value to flip the object around its center.

The default implementation calls the member function applyTransform() with a transformer corresponding to the required symmetry.

Parameters

axis	The axis around which flipping occurs.

Reimplemented from IlvGraphic.

◆ zoomable()

virtual IlBoolean IlvGraphicSet::zoomable ( ) const

virtual

Checks whether this object is zoomable.
