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.

Accessors

Accessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods IlvValueInterface::queryValue(), IlvValueInterface::queryValues(), IlvValueInterface::changeValue(), IlvValueInterface::changeValues(). This class inherits the accessors of its superclass 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
numThe 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
alignThe 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
functionThe function to be applied to the objects.
argThe 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
functionThe function to be applied to the referenced objects.
argThe 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
tThe 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
bboxThe bounding box to be set.
tA 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
spacingThe 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
pThe point to be tested.
tpThe transformed point obtained by applying the transformer t to the point p.
tA 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
dstThe destination port this object is drawn onto.
tThe transformer value. If 0, no transformation is performed.
clipThe 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
pThe point, in the graphic set coordinates system that is looked at.
tpThe point, in the coordinates system defined by t that is looked at.
tThe 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
regionThe region where objects are searched. This region is in the coordinates system defined by t.
tThe transformer.
Returns
A pointer to the first object that intersects with the region region, or 0 if there are none.

IlvGraphic* IlvGraphicSet::getObject ( IlUInt  index) const

Gets an object by index.

Parameters
indexThe index of the object that is seeked.
Returns
The index th object. The first object of the set has an index of 0.

§ getObjects()

IlvGraphic* const* IlvGraphicSet::getObjects ( IlUInt count) const

Gets an array of all stored objects.

Parameters
countIs set on return to the number of returned objects.
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
objectThe 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.

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

Parameters
rThe region to be tested.
tA 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.

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

Parameters
rThe region to be tested.
tA 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
tempIf IlTrue, highlights the object.

Reimplemented from IlvGraphic.

§ removeObject()

Parameters
modeThe drawing mode to be set.

Reimplemented from IlvGraphic.

§ setObject()

void IlvGraphicSet::setObject ( IlUInt  index,

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
indexThe index of the object that is replaced.
objectThe 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
overIf IlFalse, sets selective hidden drawing operations.

Reimplemented from IlvGraphic.

§ setPalette()

virtual void IlvGraphicSet::setPalette ( IlvPalette palette)

§ 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
axisThe axis around which flipping occurs.

Reimplemented from IlvGraphic.
