Hi all,
I want to return the info of some widgets in a 2-D grid.
I copy some example codes from the website:
TkDocs Tutorial - The Grid Geometry Manager.
and it runs OK.
But when I add this line to the end of this script( before Tk.mainloop)
TkGrid.slaves(content, nil)
Ruby complains and shows the following error message:
C:/Ruby200-x64/lib/ruby/2.0.0/tk/grid.rb:248:in slaves': undefined local variable or method args’ for TkGrid:Module (NameError)
I also read the documents about Grid.slaves on ruby-doc website:
but I don’t see any further useful information.
I wonder if there is a bug for TkGrid:Module.
Thank you for any comments.
