Constructor & Destructor Documentation

IlvChangeLayerCommand::IlvChangeLayerCommand	(	IlvManager *	m,

		int *	fromLayers = 0,
		int *	fromOrder = 0
	)

Parameters

m	The manager to which the command is added.
toLayer	The layer to which the objects are moved.
n	The number of objects to be moved. If this number is 0, the selected objects will be moved.
o	The objects to be moved (if different from 0).
fromLayers	If different from 0, the command is considered to have been executed, and this array contains the values of the layers to which the objects belonged before the move. However, it is easier to leave this parameter to 0 and let the execute method of the command determine the state to be recorded before executing the command.
fromOrder	If different from 0, the command is considered to have been executed, and this array contains the initial order of the moved objects in each layer. However, it is easier to leave this parameter to 0 and let the execute method of the command determine the state to be recorded before executing the command.
