Does anyone know of an example that shows the correct use of tk_optionMenu in Ruby/Tk? All references I can find deal with popping up a "normal" menu.
Thanks,
Ken

require 'tk'
parent = Tk.root
v = TkVariable.new
TkLabel.new(parent, :textvariable=>v).pack
TkOptionMenubutton.new(parent, v, *%w(foo bar baz hoge fuga)).pack
# other style of arguments
TkOptionMenubutton.new(:parent=>parent, :variable=>v,
:values=>%w(FOO BAR BAZ HOGE FUGA)).pack
Tk.mainloop
---------------------------------------------------------------------
However, 2nd style doesn't work because of a bug of tk/menu.rb.
Please use the following patch. I'll commit it to ruby-svn.
