Graphic class.
Library: views
The IlvSelector
class is a special kind of graphic set that handles a unique selection among the objects it holds. This class is a subtype of the IlvGraphicSet
class. You must explicitly specify the interactor if you want an interactive behavior. The default interactor name for this object is "Selector".
IlvSelectorInteractor
.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 IlvGraphicSet
and adds the following ones:
Name | Type | Equivalent methods |
---|---|---|
selection | UInt | whichSelected() , setSelected() |
IlvSelector::IlvSelector | ( | ) |
Constructor.
Initializes an empty IlvSelector
object. You can call member functions such as insertObject
to add IlvGraphic
objects to this instance.

virtual |
Computes the region needed for the drawing of the focus.
This method is called to compute the region needed for the drawing of the focus (see the method drawFocus()
).
r | The region that is updated. |
t | The transformer value. If 0 , no transformation is performed. |
Reimplemented from IlvGraphic.
|
virtual |
Draws additional drawings for an object that has the keyboard focus.
This method is called to draw additional drawings when the graphic object has the keyboard focus. The default implementation draws a rectangle around the object. The drawing will be done inside the region returned by computeFocusRegion()
.
dst | The destination port. |
palette | The palette of the object. |
t | The transformer value. If 0 , no transformation is performed. |
clip | The clipping region. |
Reimplemented from IlvGraphic.
|
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.
object | The object to be inserted. |
Reimplemented from IlvGraphicSet.
IlBoolean IlvSelector::isSelected | ( | IlvGraphic * | object | ) | const |
Returns a Boolean value indicating whether the specified graphic is selected or not.

setSelected
, whichSelected
, whichGraphicSelected
.
|
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.
object | The object to be removed from this graphic set. |
Reimplemented from IlvGraphicSet.
void IlvSelector::setSelected | ( | IlvGraphic * | object | ) |
Sets the specified graphic object as the selected object for this selector.
If object is not located in the selector, this method does nothing.
object | The new selected object. |
whichSelected
. void IlvSelector::setSelected | ( | IlShort | index | ) |
Sets the graphic object specified by its index as the selected object for this selector.
If index is not a valid index, this method deselects the selected graphic object of the selector.
index | The index of the new selected object. |
whichSelected
. IlvGraphic* IlvSelector::whichGraphicSelected | ( | ) | const |
Returns a pointer to the selected object of this selector.
