Constructor & Destructor Documentation

◆ IlvChangeLayerCommand()

IlvChangeLayerCommand::IlvChangeLayerCommand ( IlvManager m,
int  toLayer = 0,
IlUInt  n = 0,
IlvGraphic *const *  o = 0,
int *  fromLayers = 0,
int *  fromOrder = 0 
)

Constructor.

Parameters
mThe manager to which the command is added.
toLayerThe layer to which the objects are moved.
nThe number of objects to be moved. If this number is 0, the selected objects will be moved.
oThe objects to be moved (if different from 0).
fromLayersIf 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.
fromOrderIf 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.
