Graphic class.
Library: views
This section explains the concept of handle objects. An IlvGraphicHandle
object is used to reference an IlvGraphic
object. The IlvGraphicHandle
object is thus called the handle object, and the other object the referenced object.
IlvDrawSelection
class.This relationship enables you to use a handle object to indirectly access the referenced object. Also, the same referenced object can be shared among several handles. You can thus "duplicate" a complex graphic object as many times as you like by simply creating new handle objects, which all reference the same original graphic object. By referencing a complex object, instead of copying it, you save computing resources.
Another concept is that of ownership. You can make a handle object the owner of the unique referenced object with which it is associated. In this case, you no longer access the referenced object directly, but only through its handle.
When a handle owns its referenced object, deleting the handle removes both the handle and the referenced object. When the handle does not own the referenced object, a delete operation removes only the handle, leaving the referenced object intact.
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:
Name | Type | Equivalent methods |
---|---|---|
graphic | IlvGraphic | getObject() , setObject() |

IlvGraphicHandle::IlvGraphicHandle | ( | IlvGraphic * | object, |

userArg | The user argument that is passed to function. |
Reimplemented from IlvGraphic.
|
virtual |
Conditionally applies a function to the referenced object.
The function is applied only if the handle is not the owner of the referenced object. Otherwise, this member function does nothing.

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

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. |
IlTrue

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

method. If temp is IlTrue
, the object palette is inverted, and thus all the objects referencing this palette will be affected.

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).

void IlvGraphicHandle::setOwner | ( | IlBoolean | flag | ) |
Sets the ownership.
flag | The new ownership flag. If this value is IlTrue , then the handle is the owner of the referenced object with which it is associated and you should no longer access the referenced object directly. |
