Thank you for your response to my query. As I'm new to perl, can you please explain me little bit about what the following construct you added does ?

$mw->after( 'idle', [
     configure => $styleref_select_parent, 
    -background => 'cyan', 
]);
[download]

1. under what circumstances is this construct useful?
2. Also, Tk::Widget doesn't have any such method at all. So how this method gets inherited by Tk::Widget class?
3. The anonymous array passed as second parameter suprisingly has no hyphen prefixing the configure option either.
4. I was wondering if you have any answers for me to Question: 3 in the original post. (about the size of the font applied to + - indicators as well)
   Please let me know.
   Thanks again,

   • Are you posting in the right place? Check out Where do I post X? to know for sure.
   • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

     <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

   • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
   • Want more info? How to link or How to display code and escape characters are good places to start.
