Detailed Description

Graphic class.

Library: views

IlvGraphic is an abstract base class that:

applies geometric transformations to objects,
changes graphic properties such as colors, fonts and patterns gathered in an IlvPalette instance associated with the graphic object.

Rogue Wave Views graphic objects inherit attributes from this class. A graphic object is capable of drawing itself at a given destination port, with the possibility of transforming the object's coordinates according to an associated object of the IlvTransformer class. The shapes of graphic objects are defined by the user and made concrete by various drawing member functions. Other member functions provide information about the graphic objects, and carry out geometric tests concerning the shapes being used. For example, you can check whether or not a point with given coordinates lies inside a certain shape.
This class has member functions that set and change geometric dimensions. Some member functions set and get user properties that can be associated with an object for application-specific purposes. IlvGraphic does not implement these member functions. They are declared as virtual member functions, and defined to do operations in the classes that inherit IlvGraphic attributes. Although the member functions for manipulating geometric shapes and graphic attributes are present, they do nothing. A fundamental inherited class is IlvSimpleGraphic. It implements all functionalities of the IlvGraphic class, and adds to each instance an IlvPalette resource used to draw the object. It also implements real geometric-management member functions. IlvGraphic has groups of member functions that deal with the following items:

Geometric Properties
Graphic Properties
Named Properties
Resource Management
Gadget Properties
Focus Chain Management
Tag Management
User Properties
Class Information
Class Attributes
Input/Output Operations

IlvGraphic is an abstract class with no constructor. However, all derived graphic classes have two constructors that make it easier to create subclasses. Use the macro DeclareIOConstructors(className) to declare these constructors in the class definition.

Applies a function to objects that are referenced by another object.

Implements a technique for applying a function to objects that are referenced by another object.

Parameters:

	function	The function to be applied.
	arg	An argument parameter.

Reimplemented in IlvGraphicHandle, IlvDrawSelection, and IlvGraphicSet.

virtual void IlvGraphic::applyResources	(	const char *	storageName,
		const char *	storageClassName,
		const char *	objectName,
		const char *	objectClassName,
		IlvDisplay *	display = `0`
	)			`[virtual]`

Applies resources on a graphic object.

Searches for resources that match storageName.objectName.resource, or storageName.objectClassName.resource, or storageClassName.objectName.resource, or storageClassName.objectClassName.resource, in this order, and applies these resources to the object.
The resources taken into account by the class IlvGraphic are only geometric:

x
y
h or height
w or width

The class IlvSimpleGraphic also applies the following graphic resources, if and only if the object has the default display palette:

foreground
background
font
pattern
colorPattern
lineStyle
lineWidth
fillStyle
arcMode
fillRule

Parameters:

	storageName	The storage name.
	storageClassName	The generic name of the storage instance.
	objectName	The object name.
	objectClassName	The generic name of the object class.
	display	The display where this object is created.

Reimplemented in IlvSimpleGraphic.

virtual void IlvGraphic::applyTransform ( const IlvTransformer * t ) [pure 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.

Warning:: [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.

Implemented in IlvGadget, IlvArc, IlvCircularScale, IlvEllipse, IlvFilteredGraphic, IlvGauge, IlvGraphicHandle, IlvTransformedGraphic, IlvFixedSizeGraphic, IlvIcon, IlvLabel, IlvListLabel, IlvLine, IlvMarker, IlvGraphicPath, IlvPolyPoints, IlvPolySelection, IlvRectangle, IlvViewRectangle, IlvScale, IlvRectangularScale, IlvDrawSelection, IlvGraphicSet, IlvTimeScale, IlvZoomableIcon, IlvZoomableLabel, and IlvGraphicCOMAdapter.

virtual IlBoolean IlvGraphic::applyValue ( const IlvValue & val ) [virtual]

Apply an accessor.

This member function is called by changeValue(s) functions and must not be called directly.
Moreover, no drawing operations are carried out here (and should not be). The drawing operations are called by the changeValue(s) member functions, after having processed the call to applyValue. If you add your own new IlvValue, do not forget to override applyValue as well as changeValue and queryValue, since applyValue is called by changeValue.

Parameters:

val

The new value of the accessor.

Reimplemented in IlvGraphicHandle, IlvGraphicInstance, and IlvGraphicCOMAdapter.

virtual void IlvGraphic::boundingBox	(	IlvRect &	bbox,
		const IlvTransformer *	t = `0`
	)			const `[pure virtual]`

Retrieves the bounding box of the graphic object.

Sets bbox, the rectangle reference parameter, to be the bounding box of the object.

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 virtual 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 in IlvFilteredGraphic, IlvGraphicHandle, IlvTransformedGraphic, IlvFixedSizeGraphic, IlvIcon, IlvLabel, IlvListLabel, IlvGraphicSet, IlvZoomableIcon, and IlvZoomableLabel.

IlBoolean IlvGraphic::intersects ( const IlvRect & r ) const

IlBoolean IlvGraphic::intersects	(	const IlvRect &	r,
		const IlvRect &	tr,
		const IlvTransformer *	t = `0`
	)			const

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

Behaves similarly for the transformed rectangle tr obtained by applying the transformer t to the rectangle r. That is, this function checks if the object intersects with the rectangle r, in the object's coordinate system, or with tr when this object is applied the possible transformer t. The tested regions are the given rectangle and the bounding box of the object.

Parameters:

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

Returns:: IlTrue when the rectangle r overlaps the bounding box of the object, and IlFalse when the rectangle r does not overlap the bounding box.

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.

virtual void IlvGraphic::invert ( IlBoolean temp = ((IlBoolean) 0) ) [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.

	)			const `[virtual]`

Prints for debugging purposes.

Use for debugging purposes. Depending on the debugging level given as the level parameter, basic information about this object is printed to out. Basic implementation prints the object class name, and its bounding box. When this object is defined by another object (that is, if it is a referenced object), this subobject is described only if the level parameter is not zero. When this object is defined by a group of objects, these subobjects are defined themselves if the level parameter is not zero. In general, the higher level is, the more information you get about the object.

Parameters:

	out	The output stream.
	level	The debugging level. If 0, subobjects are not described.

Returns:: The multiple values in values and the number of values in count.

static IlvGraphic* IlvGraphic::read	(	IlvInputFile &	file,
		IlvPalette *	palette
	)			`[static]`

Reads an object description from a file.

Reads an object description from the file input, given the palette graphic attributes. It reads the information that was saved by the member function write to be able to create a new instance of this object. Usually, because of the availability of the constructor that expects an IlvInputFile, read should be equivalent to:

 IlvGraphic*
 MyClass::read(IlvInputFile& file, IlvPalette* palette)
 {
     return new MyClass(file, palette);
 }

In the following example, the static member function read of the IlvLabel class could have the following form:

 IlvGraphic*
 IlvLabel::read(IlvInputFile& file, IlvPalette* pal)
 {
     IlvPoint pos;
     file.getStream() >> pos;     // Read the position field
     return new IlvLabel(pal->getDisplay(), pos,
     IlvReadString(file.getStream()), pal);
 }

Parameters:

	file	The name of the file to be read from.
	palette	The name of the palette for the object.

See also:: DeclareTypeInfoRO, DeclareTypeInfo, IlvPredefinedIOMembers.

Warning:: [note] The read method is not capitalized like other static methods so that it is consistent with the write method.

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 in IlvGadget, IlvSimpleGraphic, IlvFilteredGraphic, IlvGauge, IlvReliefGauge, IlvGraphicHandle, IlvGraphicInstance, IlvOutlinePolygon, IlvGraphicPath, IlvPolySelection, IlvReliefLine, IlvReliefRectangle, IlvDrawSelection, IlvGraphicSet, IlvShadowRectangle, and IlvGraphicCOMAdapter.

virtual void IlvGraphic::setName ( const char * name ) [virtual]

Sets the name of the object.

Sets the name of the object to a copy of the string newName. If newName is 0, then the object loses its name. This function should not be called if the object is stored in a manager. Use IlvManager::setObjectName instead. If the object is stored in a SmartSet, the name is rebuilt internally.

Parameters:

name

The new name of the object.

IlvNamedProperty* IlvGraphic::setNamedProperty ( IlvNamedProperty * property )

Sets a named property on the object.

Associates the named property property with this object. This function returns the named property that was previously associated with this object having the same name, so that you can delete it or keep it for further handling. If no previous named property was associated with this object having the name property, this function returns 0.

Parameters:

property

The name of the property.

Returns:: A pointer to the previous named property object, or 0.

virtual void IlvGraphic::setNeedsInputContext ( IlBoolean val ) [virtual]

Specifies whether the graphic object should have locale dependent input.

Any input field object will automatically connect to an input method so that input can be done in the current locale, as long as IlvSetLocale has been called, and IlvGraphic::needsInputContext returns IlTrue.

If an application wants to disallow this behavior, that is wants only ASCII input for an object instance, it has to call this method with the parameter value IlFalse.

Parameters:

val A Boolean value specifying whether the graphic object should react to localized input (IlTrue) or not (IlFalse).

See also:: IlvSetLocale, needsInputContext.

void IlvGraphic::setNextFocusGraphic ( IlSymbol * name )

Sets the object to be next in the focus chain.

Sets as the next object in the focus chain the object whose name is identified by name. This symbol must be built from the name of the object you want to be next in the focus chain. This next object must therefore have a name.

Parameters:

name

The name of the object to be next in the focus chain.

virtual void IlvGraphic::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 in IlvGadget, IlvSimpleGraphic, IlvFilteredGraphic, IlvGauge, IlvGraphicHandle, IlvGraphicInstance, IlvOutlinePolygon, IlvReliefLine, IlvReliefRectangle, IlvDrawSelection, IlvGraphicSet, IlvShadowRectangle, and IlvGraphicCOMAdapter.

virtual void IlvGraphic::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 in IlvGadget, IlvSimpleGraphic, IlvFilteredGraphic, IlvGauge, IlvReliefGauge, IlvGraphicHandle, IlvGraphicInstance, IlvLabel, IlvOutlinePolygon, IlvGraphicPath, IlvViewRectangle, IlvReliefLine, IlvReliefRectangle, IlvScale, IlvDrawSelection, IlvGraphicSet, IlvShadowRectangle, and IlvGraphicCOMAdapter.

virtual void IlvGraphic::setPattern ( IlvPattern * pattern ) [virtual]

Sets the pattern of the object.

Parameters:

pattern

The new pattern.

Reimplemented in IlvGadget, IlvSimpleGraphic, IlvFilteredGraphic, IlvGraphicHandle, IlvGraphicInstance, IlvReliefRectangle, and IlvGraphicSet.

void IlvGraphic::setPreviousFocusGraphic ( IlSymbol * name )

Sets an object as previous in the focus chain.

Sets as the previous object in the focus chain the object whose name is identified by name. This symbol must be built from the name of the object you want to be previous in the focus chain. This previous object must therefore have a name.

Parameters:

name

The name of the object set as previous in the focus chain.

void IlvGraphic::setProperty	(	const IlSymbol *	key,
		IlAny	value
	)

Sets a property of the object to a value.

Sets the property key of this object to value if value is not 0. If it is 0, this function removes the property.

Parameters:

	key	The key to be set.
	value	The value to be set.

virtual void IlvGraphic::setSensitive ( IlBoolean value ) [virtual]

Sets the sensitivity of the object.

Sets the sensitivity of the graphic object to the value sensitive.

Parameters:

value

The sensitivity value.

virtual void IlvGraphic::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 in IlvArc, IlvLine, and IlvGraphicSet.

virtual void IlvGraphic::translate	(	IlvPos	dx,
		IlvPos	dy
	)			`[virtual]`

Applies a transformation function on a graphic object.

Translates the position of the object by the vector (dx, dy). The default implementation calls the member function applyTransform that computes the corresponding translation transformer.

Parameters:

	dx	The `x` coordinate vector.
	dy	The `y` coordinate vector.

void IlvGraphic::w ( IlvDim w )

Sets the width value of the object.

This member function calls boundingBox and resize to set the w (width) value.

Parameters:

w

The width value.

IlvDim IlvGraphic::w ( ) const

Gets the width value of the object.

This member function calls boundingBox and retrieves the w (width) value.

Returns:: The width value.

virtual void IlvGraphic::write ( IlvOutputFile & output ) const [pure virtual]

Writes an object description to a file.

Writes out, in a file, the object description. This description contains all the information necessary to create an exact copy of this object by means of the member function read. Information concerning any IlvPalette object attached to this object is written out by the object containers. All other information, such as the position and size of the object, is written out by this virtual member function.
For example, suppose we have an IlvLabel class that implements a graphic object drawn as a text string at a given position. It maintains its position in an internal IlvPoint field called _position and its textual content in an internal character array field called _text. The only information we need to save is the contents of those fields. So, the member function write of such an object should have the following form:

 void
 IlvLabel::write(IlvOutputFile& file) const
 {
     // Save the position field
     file.getStream() << IlvSpc() << _position;
     // Save the text field
     IlvWriteString(file.getStream(), _text);
 }

Parameters:

output

The the output file to be written to.
