As I was exploring gtk in ruby I found myself frustrated with the inability to create nested widgets in equally nested code. Such as:

$main = Gtk::Window.new

$main << Gtk::HBox.new do |b|

  b << Gtk::Button.new(“click me”)

  b << Gtk::VBox.new do |v|

    … etc etc

  end

end

No problem, eigenclasses to the rescue! I just add this simple thing (to a lib or just the beginning of my file):

class << Gtk::Widget

  def new *args, &block

    x = super

    yield x if block

    x

  end

end

That’s all, now you can use good ol’ ruby blocks to make GUI programming less obscene.
