Detailed Description

Selection objects for grapher nodes.

Library: ilvgrapher

This class implements a selection object that displays the connection pins of a grapher node. Instances of this class can be associated with a selected node by using the IlvManager::setMakeSelection method. The selected node will then appear as in the following figure:

.

The class is used by the interactor of the pin editor, which is implemented by the IlvPinEditorInteractor class.

◆ getActivePinIdx()

IlUInt IlvGraphNodeSelection::getActivePinIdx ( ) const

Returns the index of the active connection pin.

Returns
The active pin index.

◆ getPin()

IlvGrapherPin* IlvGraphNodeSelection::getPin ( ) const

Returns the grapher pin of the associated object.

Returns
The grapher pin of the associated object.

◆ setActivePinIdx()

void IlvGraphNodeSelection::setActivePinIdx ( IlUInt  idx)

Sets the index of the active connection pin.

For editing purposes, the selection object can store the index of one of the connection pins, referred to as the active or selected pin. This method lets you specify idx as the index of the pin.
