Examples of net.sf.rej.gui.action.GroupAction

net.sf.rej.gui.action.GroupAction
Utility class to group to Undoable objects together. This GroupAction can then be added into the Undo stack, causing the two or more grouped actions to always execute/get undone at the same time. A group of Undoable objects A, B and C will always be executed in the order:
A
B
C

And always undone in the order:
C
B
A
