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 -
IlvManager::group
, IlvManager::unGroup
. IlvGraphicSet::IlvGraphicSet | ( | ) |
Constructor.
Initializes an empty IlvGraphicSet
object, which is a skeleton. You can call member functions such as addObject
to add IlvGraphic
objects to the IlvGraphicSet
object.
IlvGraphicSet::IlvGraphicSet | ( | int | num... | ) |
Constructor.
Initializes an IlvGraphicSet
object on the basis of the nObjects
parameter. IlvGraphic
objects are provided as the parameters following num.
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 | ( | ) |
Destructor.
The destructor destroys all the objects that are stored in this graphic set.
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.
Adds a property to this object's class.
This static function associates the given value with the given key for the class of this object only.
key | The key to be associated. | |
value | The value to be associated. |
Reimplemented from IlvGraphic.
Reimplemented in IlvSelector.
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.
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. |
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.
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.
virtual void IlvGraphicSet::applyReferences | ( | IlvApplyObject | function, | |

with the arguments function
and argument
for each object stored in the set.

Reimplemented from IlvGraphic.
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
.
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.t | The transformer value. If 0, no transformation is performed. |

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. When there is no transformation, t is set to 0
.
bbox | The bounding box to be set. | |
t | A transformer value or 0 if there is no transformation. |
Implements IlvGraphic.

const IlvPoint & | tp, | |||
const IlvTransformer * | t = 0 | |||
) | const [virtual] |

if all rectangles that define the region completely lie inside the object. Reimplemented from IlvGraphic.
virtual IlBoolean IlvGraphicSet::intersects | ( | const IlvRegion & | r, | |
const IlvTransformer * | t = 0 | |||

) and IlFalse
when this is not the case. Reimplemented from IlvGraphic.
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.
temp | If IlTrue , highlights the object. |
Reimplemented from IlvGraphic.
IlBoolean IlvGraphicSet::isSubtypeOf | ( | const IlvClassInfo * | classInfo | ) | const |
Checks whether this object's class is a subclass.
This method is equivalent to getClassInfo()->isSubtypeOf(classInfo)
.

This method is equivalent to getClassInfo()->isSubtypeOf(parentClass)
.
parentClass | A string representing the parent class. |
IlTrue
or IlFalse
, depending on whether or not this object's class inherits parentClass attributes. The parentClass parameter should be a string representing the class name of an IlvGraphic
subclass. A call to this member function for a given class instance returns IlTrue
if given the name of its class. Reimplemented from IlvGraphic.
Reimplemented in IlvSelector.
virtual void IlvGraphicSet::print | ( | ILVSTDPREF ostream & | out, | |
int | level = 0 | |||
) | 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.
out | The output stream. | |
level | The debugging level. If 0, subobjects are not described. |
Reimplemented from IlvGraphic.

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); }
file | The name of the file to be read from. | |
palette | The name of the palette for the object. |

, 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.
axis | The axis around which flipping occurs. |
Reimplemented from IlvGraphic.
virtual void IlvGraphicSet::write | ( | IlvOutputFile & | output | ) | const [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); }
output | The the output file to be written to. |
DeclareTypeInfo
. Implements IlvGraphic.
Reimplemented in IlvSelector.
virtual IlBoolean IlvGraphicSet::zoomable | ( | ) | const [virtual] |
Checks whether this object is zoomable.
IlTrue
if the graphic object can be zoomed, and IlFalse
otherwise. See the member functions IsZoomAllowed
and AllowZoom
below. Reimplemented from IlvGraphic.
