                rte.status = rteTA.length + "/" + rteTA.maxChars;
            }

    <mx:RichTextEditor id="richTextEditor"
            title="Rich Text Editor"
            height="200"

If you want to set a style on the RichTextEditor control’s status message, add the following snippet to the previous example:

<mx:Style>
    RichTextEditor {
        statusStyleName: richTextEditorStatus;
    }

    .richTextEditorStatus {
        color: red;
        fontWeight: bold;
    }
</mx:Style>
