Manager command class.
Library: ilvmgr
The class IlvManagerCommand
is a subclass of IlvCommand
that makes the undo mechanism provided in earlier versions of Rogue Wave Views compatible with the command history mechanism provided in Rogue Wave Views 4.0. It is provided for compatibility purposes only. New command classes should inherit directly from IlvCommand
and not from IlvManagerCommand
. With the command history mechanism, we recommend that you let the manager and the commands store the various states and apply the modifications in the appropriate order, instead of instantiating commands and adding them to the command history. Doing so will allow you to encapsulate the result of commands in a more efficient way and redo them more easily.
For example, if you want to change the layer of an object and record this change, we suggest that you proceed like this:
and not as shown below, which is more complex and inaccurate:
IlvGrapher
