set width of editor area while creating fckeditor

Hi All,

I am using FCKEditor 2.6.5 in my webapplication.

I am using following code to create fckEditor on my webpage.

var oFCKeditor = new FCKeditor( 'description' ) ;
                                    oFCKeditor.Config['EditorAreaCSS'] = '<%=oDocumentEdit.call ("Get_WebsiteCSSUrl")%>/ElectosStyles.css' ;
                                    oFCKeditor.ToolbarSet = "Electos";
                                    oFCKeditor.BasePath = "../FCKeditor/";
                                    oFCKeditor.Width = 650;
                                    oFCKeditor.Height = 210;
                                    oFCKeditor.Config['StyleNames'] = ';Emphasized Text;Heading 1;Heading 2;Heading 3;Normal' ;
                                    oFCKeditor.Config['StyleValues'] = ';EmphasizedText;Heading1;Heading2;Heading3;Normal' ;
                                    oFCKeditor.Value = '<%= sDescription%>';
                                    oFCKeditor.Create() ;

I want to set the width of editor area dynamically while generating FCKEditor.
The line : oFCKeditor.Width = 650; ...is setting width of whole FCKEditor. But I want to set the width of only editor area to a different value (which is dynamic)..

Is there any FCK Editor property which I can use for this while creating FCKEditor ? Or is there any other way to achieve this?
