Detailed Description

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".

See also

IlvSelectorInteractor.

Accessors\nAccessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods <tt>IlvValueInterface::queryValue()</tt>, <tt>IlvValueInterface::queryValues()</tt>, <tt>IlvValueInterface::changeValue()</tt>, <tt>IlvValueInterface::changeValues()</tt>.\n\n\nThis class inherits the accessors of its superclass \c IlvGraphicSet and adds the following ones:

Name	Type	Equivalent methods
selection	UInt	whichSelected(), setSelected()

Constructor & Destructor Documentation

IlvSelector()

IlvSelector::IlvSelector

(

)

Constructor.

Initializes an empty IlvSelector object. You can call member functions such as insertObject to add IlvGraphic objects to this instance.

Member Function Documentation

computeFocusRegion()

virtual void IlvSelector::computeFocusRegion ( IlvRegion &  r, const IlvTransformer *  t = 0  ) const

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()).

Parameters

r	The region that is updated.
t	The transformer value. If 0, no transformation is performed.

Returns

The computed region.

Reimplemented from IlvGraphic.

drawFocus()

virtual void IlvSelector::drawFocus ( IlvPort *  dst, const IlvPalette *  palette, const IlvTransformer *  t = 0, const IlvRegion *  clip = 0  ) const

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().

Parameters

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.

insertObject()

virtual void IlvSelector::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

object

The object to be inserted.

Reimplemented from IlvGraphicSet.

isSelected()

IlBoolean IlvSelector::isSelected

(

IlvGraphic *

object

)

const

Returns a Boolean value indicating whether the specified graphic is selected or not.

Parameters

object

The graphic object.

Returns

A Boolean value indicating whether the specified graphic is selected or not.

See also

setSelected, whichSelected, whichGraphicSelected.

removeObject()

virtual void IlvSelector::removeObject ( IlvGraphic *  object )

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.

Parameters

object

The object to be removed from this graphic set.

Reimplemented from IlvGraphicSet.

setSelected() [1/2]

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.

Parameters

index

The index of the new selected object.

See also

whichSelected.

setSelected() [2/2]

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.

Parameters

object

The new selected object.

See also

whichSelected.

whichGraphicSelected()

IlvGraphic* IlvSelector::whichGraphicSelected

(

)

const

Returns a pointer to the selected object of this selector.

Returns

A pointer to the selected object of this selector.

See also

setSelected, whichSelected.

whichSelected()

IlShort IlvSelector::whichSelected

(

)

const

Returns the index of the selected object of this selector.

Returns

The index of the selected object of this selector.
