I just feel this would be a nice feature, but not sure how many people needed, and I know it is not trivial ( check all commands, make sure they have getter/setter behaviour, and wrap them like options ... ). I am not strongly needed, but if many people think that would be nice, then maybe give it a try? ;-) BTW: if we really do it, then we may need to keep maintenance in the future for new version of TK ( maybe new command come out and need to wrap ... etc ) So, think again those complexity ... > I thought that is enough because canvas items needs a parent > canvas widget. > Don't you think so? I think so too. :-) I just try to write a quick demo as short as possible, then that error came out. After your explication, I know what I have to rewrite it ... Here is the classic way: require 'tk' ; TkCanvas.new { |c| TkcRectangle.new(c, 1, 1, 2, 2) }.pack; Tk.mainloop My short version which not works: require 'tk'; TkcRectangle.new(TkCanvas.new.pack, 1,1,2,2); Tk.mainloop; Just rewrite it to become: require 'tk/canvas.rb'; TkcRectangle.new(TkCanvas.new.pack, 1,1,2,2); Tk.mainloop; and it is short and works fine. Thank you again for your help.
