	      Create a PatternCmd, optionally specifying the PSPattern that components should adopt.

       virtual void Execute()
	      PatternCmd extends Execute to set the value of the affected editor's PatternVar instance, if it defines one.

NAME

       BackCmd, FrontCmd, GroupCmd, UngroupCmd - commands for modifying components structurally

SYNOPSIS

       #include <Unidraw/Commands/struct.h>

DESCRIPTION

       BackCmd,  FrontCmd,  GroupCmd, and UngroupCmd are purely interpretive commands for altering the structure of their editor's component.  All
       redefine their Execute and Unexecute operations to let the editor's component interpret them as it wishes.

BACKCMD PUBLIC OPERATIONS

       BackCmd(ControlInfo*)
       BackCmd(Editor* = nil)
              Construct a new BackCmd.

FRONTCMD PUBLIC OPERATIONS

       FrontCmd(ControlInfo*)
       FrontCmd(Editor* = nil)
              Construct a new FrontCmd.

GROUPCMD PUBLIC OPERATIONS

       GroupCmd(ControlInfo*, GraphicComp* = nil)
       GroupCmd(Editor* = nil, GraphicComp* = nil)
              Create a new GroupCmd, optionally specifying the component into which components will be grouped.

       virtual void Execute()
       virtual void Unexecute()
              Execute will set the value of the _executed protected member variable to true as a side effect if anything was grouped.   Similarly,
              Unexecute will set reset the value to false as a side effect the operation was undone.

       GraphicComp* GetGroup()
       void SetGroup(GraphicComp*)
              Get or set the component into which components will be grouped.  SetGroup will not delete the old value.

UNGROUPCMD PUBLIC OPERATIONS

       UngroupCmd(ControlInfo*)
       UngroupCmd(Editor* = nil)
              Construct a new UngroupCmd.

       virtual void Execute()
       virtual void Unexecute()
              Execute  will  set  the  value of the _executed protected member variable to true as a side effect if anything was ungrouped.  Simi-
              larly, Unexecute will set reset the value to false as a side effect the operation was undone.

       Clipboard* GetKids()
       void SetKids(Clipboard*)
              Explicitly set and get a clipboard containing the child components that were ungrouped, which is stored in the _kids protected  mem-
              ber.   UngroupCmd  does not initialize this member; it merely provides the storage as a convenience to components that interpret the
              command and need a place to store the ungrouped children to support reverse execution.  However, UngroupCmd  deletes  the  clipboard
              (if it exists) in ~UngroupCmd. SetKids will not delete the old value.
