reset undo history

[Cean Perkins]

a Simple function to reset the undo history so that you can reuse an editor window with out having to reload in order to clear the current undo/redo history.

The function is very simple .. just resets the undo vars

FCKUndo.resetUndoState = function()
{
   //simple reset of the undo history
   this.SavedData = new Array() ;
   this.CurrentIndex = -1 ;
   this.TypesCount = 0 ;
   this.Changed = false ;
   this.Typing = false ;
   this.SaveLocked = false ;
   FCK.Events.FireEvent( "OnSelectionChange" ) ; // this updates the undo and redo toolbar status
}

To make this actually really useful ... changes to both fck.js and fckundo.js need to be made:

fck.js

	ResetUndoState : function()
	{
		FCKUndo.resetUndoState() ;
	},

fckundo.js

FCKUndo.resetUndoState = function()
{
   //simple reset of the undo history
   this.SavedData = new Array() ;
   this.CurrentIndex = -1 ;
   this.TypesCount = 0 ;
   this.Changed = false ;
   this.Typing = false ;
   this.SaveLocked = false ;
}

The function can then be called through the editor instance EG oEditor.ResetUndoState();

or inside plugins EG: FCKUndo.resetUndoState(); FCK.Events.FireEvent("OnSelectionChange");

Thanks for the suggestion. But 2.6.4 is going to be released soon so we're not accepting feature requests for it right now.

[Artur Formella]

Already fixed in V3: #3662

[Frederico Caldeira Knabben]

We'll keep this as a V3 only feature.
