CLASS DESCRIPTION
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.
