I can't figure out how to use this widget properly. I have two major
problems with it:
Please run '<ruby-src>/ext/tk/sample/tkextlib/bwidget/demo.rb',
and see '<ruby-src>/ext/tk/sample/tkextlib/bwidget/tmpldlg.rb'.
1. Tk::BWidget::Dialog don't seem to have a "buttons" option? But
without a "buttons" option, options like "cancel", "default" and
"separator" don't really make sense, IMHO.
Use Tk::BWidget::Dialog#add to add buttons.
2. It's draw() method returns the id of the widget instead of an indication
which button was pressed.
Please see the next example.

require 'tk'
require 'tkextlib/bwidget'
d = Tk::BWidget::Dialog.new(:relative=>Tk.root, :modal=>:local,
:separator=>true, :title=>'Dialog Test',
:side=>:bottom, :anchor=>:c,
:default=>0, :cancel=>3)
d.add(:text=>'btn0', :command=>proc{d.enddialog('btn0 is pressed')})
d.add(:text=>'btn1', :command=>proc{d.enddialog('btn1 is pressed')})
d.add(:text=>'btn2') # use default cmd => return a string of the index number
d.add(:text=>'btn3', :command=>proc{d.enddialog('btn3 is pressed')})
p d.current_itemconfiginfo(0)
# f = d.get_frame
d.get_frame{|f|
TkLabel.new(f, :text=>'Here is a frame of the dialog').pack
TkLabel.new(f, :text=>'Please lay-out your widgets here.').pack
}
TkButton.new(:text=>'show dialog', :command=>proc{p d.draw}).pack
Tk.mainloop

BTW: There seems to be one more widget set called iwidgets. Anybody knows
what it is?
If you can use "iwidgets", it may be enough for your purpose to imitate
'<ruby-src>/ext/tk/sample/tkextlib/iwidgets/sample/dialog.rb'.
If you want to install "iwidgets" ([incr Widgets]) from its source,
you have to compile it.
However, BWidgets doesn't need compile, because it witten in pure Tcl/Tk.
