CLASS DESCRIPTION    [Toc]    [Back]

	  The VkCmdManager class provides a central place for executing
	  commands and managing	them on	a undo/redo stacks. The	management of
	  the VkCmdManager is left to the application, which may wish to have
	  a single CmdManager, or multiple instances, depending	on the
	  application architecture.

	  The VkCmdManager class can execute a cmd given a VkCmd object, a
	  VkCmdFactory object, or a idintifying	string,	if the VkCmd has been
	  registered with the VkCmdRegistry. Commands are executed by calling
	  run():



	      cmdManager->run("CutCommand");


	  an optional argument to all forms of run can be supplied to be
	  passed to the	command	(via the VkCmd::setData() method) before the
	  cmd is executed. This	data is	uninterpreted by the VkCmdManager, and
	  must be agreed upon by the cmd object	and the	caller.

	  Interaction with the undo management facilties of the	VkCmdManager
	  are most easily accessed by the VkMenu class's addUndoAction() and
	  addRedoAction() methods. The methods connect an instance of
	  VkCmdManager with the	appropriate menu commands.
