Close dialog from parent window

No one help

I am still trying to find out a solution...

I had a look at the class source/internals/fckdialog_gecko.js. There is a line of code that call the standard window.open() method

        if ( !parentWindow )
      parentWindow = window ;

        var oWindow = parentWindow.open( '', 'FCKeditorDialog_' + dialogName, sOption, true ) ;

   if ( !oWindow )
   {
      alert( FCKLang.DialogBlocked ) ;
      FCKFocusManager.Unlock() ;
      return ;
   }

   oWindow.moveTo( iLeft, iTop ) ;
   oWindow.resizeTo( dialogWidth, dialogHeight ) ;
   oWindow.focus() ;
   oWindow.location.href = pageUrl ;

   oWindow.dialogArguments = dialogInfo ;

   // On some Gecko browsers (probably over slow connections) the
   // "dialogArguments" are not set to the target window so we must
   // put it in the opener window so it can be used by the target one.
   parentWindow.FCKLastDialogInfo = dialogInfo ;

   this.Window = oWindow ;

They do not set the dialog window variable to the parent window.... So how can i get it

I tried to set oWindow to the parentWindow like this :

      parentWindow.LastFCKDialogOpened = oWindow;

But then...I can not get it from the parent window....

The param parentWindow is always passed with NULL value...

I dont know if this parentWindow is the iframe that contains the FCKEditor area, or the main parent window...

Anyone can help me please , I am sure that there should be some way to do this....

This project is using version 2.4 FCKEditor....and I can not update to 3x....because they 've already built many things, plugins, toolbars...and stuffs like that..

Thanks for reading,

        var f = document.getElementById('designTextarea___Frame');
   var fDoc = f.contentWindow;
   fDoc.LastFCKDialogOpened.close();
