WebDialogs: To sub-class or not?

[Jim]

Just curious if anyone had any thoughts on creating webdialogs. I've seen 2 ways to use them: sub-classing and instancing:

class MyDialog < UI;;WebDialog
...
end

or

dlg = UI;;Webdialog.new({})

Any advantages one way or the other?

Hi Jim,
Although I've only coded few WebDialogs, I'll vote for sub-classing. This is a good way for coding 'generic' attributes and methods if you have many other dialogs that will use them, by first extending the class.

a) subclassing and instancing
b) instancing

If you only need a window to display information, b) would do it. But if your dialog is more complex, subclassing seems to be a good choice, because you can let your class do a lot of things, i.e. generating the HTML by overriding the original set_html method:

class AzubyDialog < UI;;WebDialog
  private
    def generate_html arg
      s = ''
      # TODO; implement your HTML generator code
      s
    end
  public
    def set_html arg
      super(arg.kind_of?(String) ? arg ; generate_html(arg))
    end
end
