Ruby/Tk: How to colorize a Treeview?
in [Ruby]
|
From: Albert Schlef on 21 Mar 2010 00:48 I have an item in my Treeview that I want to highlight. I have this code: require 'tk' tree = Tk::Tile::Treeview.new.pack tree.insert('', 'end', :text => 'blah blah', :tags => ['important']) tree.tag_configure('configure', 'important', :background => 'yellow') Tk.mainloop But the item isn't shown with its background painted in yellow. I took that code from: http://www.tkdocs.com/tutorial/tree.html#appearance That article mentions this bug in Ruby/Tk. Is it possible to add some code in Ruby to fix the bug? (I'm using Tk 8.4, Tile, and Ruby 1.8.7p174, Ubuntu.) -- Posted via http://www.ruby-forum.com/.

Please try "tree.tag_configure('important', :background => 'yellow')". I think the bug is already fixed (at least, on the latest Ruby/Tk). -- Hidetoshi NAGAI (nagai(a)ai.kyutech.ac.jp)

Thanks. Upgrading Ruby/Tk isn't a viable solution for me because I can't force my users to upgrade theirs. Well, this isn't critical. I can live without this feature. (BTW, I'm using the most recent Ruby 1.8 Ubuntu provides, which is 1.8.7.174, and the bug is there.) Anyway, thanks, Hidetoshi. I appreciate it that you're here to answer our questions. -- Posted via http://www.ruby-forum.com/.
