If you don't return $self, you're taking the decision for the user. Which isn't very friendly.

That's actually a better argument than it might seem like, but, as I wrote in my root node update, if you don't write separate mutators, but rather a single central property setter method, you completely obviate the need for chaining to begin with:

$window->set( title => 'foo', border => 20 );

And I was almost going to point out that you were picking up the wrong widget in your rewrite of the chaining because the en passant assignment in

my $button = $window->child->border(20);

misled me.

Really, don't mix these things. It seriously makes reading the code an excercise in frustration.

Makeshifts last the longest.

Title:
Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":



  • 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 or How to display code and escape characters are good places to start.
