C# Class SIL.FieldWorks.FDO.ExtraPropChangedAction

Generate an additional PropChanged as part of an Undo or Redo action. A typical usage is pretending that the row that is the target of a dependent clause annotation has changed in its parent. Note that we create TWO of these, one that is the first action in the group, and one that is the last. The first is for Undo, and updates the ribbon to the appropriate state for when the action is undone. (It needs to be first so it will be the last thing undone.) The last is for Redo, and updates the ribbon after the task is redone (needs to be last so it is the last thing redone). A typical usage is using (new ExtraPropChangedInserter(actionHandler, sda, hvo, tag, ihvo, chvoIns, chvoDel) { // Do the changes which require the extra propchanged before and after. }

Public Methods

Method	Description
AddAndInvokeIfRedo ( IActionHandler actionHandler, ISilDataAccess sda, int hvo, int tag, int ihvo, int chvoIns, int chvoDel, bool fForRedo ) : ExtraPropChangedAction	Make an instance and add it to the undo stack. Also, if it's the 'redo' action added after the actual changes (fForRedo is true), issue the propchanged at once to complete the original action.
Commit ( ) : void	Called when action can no longer be undone or redone
ExtraPropChangedAction ( ISilDataAccess sda, int hvo, int tag, int ihvo, int chvoIns, int chvoDel, bool fForRedo ) : System	Make one.
Redo ( ) : bool	Redo it.
SameInfo ( int hvo, int tag, int ihvo, int chvoIns, int chvoDel, bool fForRedo ) : bool	Mainly for testing...check whether this one has the same info as the arguments. May use -1 as 'don't care' argument for ihvo, chvoIns, chvoDel.
Undo ( ) : bool	Undo it.
