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>
