I am playing with the ListView example and trying to turn it into a VR::TreeView. I am unable to figure out how to add items. in the listviewobject example rows are added row = add_row() row[:join] = VR::CalendarCol.new DateTime.new(1987, 5, 11, 6, 43, 0) row[:name] = DataObject.new("Billy Vincent", ... row[:quote] = VR::TextCol.new "There are two ways ..." The doc says to use add_row(nil, Hash) to add a row in a TreeView. If I try this I get ViewCommon.rb:132:in `method_missing': undefined local variable or method `args' for #<ListViewObjectsGUI:04EE4FA8 ptr=02DFA160> (NameError) What am I missing on using a Vr::TreeView? Thanks,

I think you can just use the normal #append() method: child = @treeview.append(parent) child[0] = "Hello" child[2] = "World" Eric

Hi: You're right that it doesn't work the same as the ListView. I've fixed it so the treeview's #add_row method works exactly like the ListView's with the exception that you must pass the parent iter argument. I've updated the program. I will push it to rubygems.org later today. Also, I've written a treeview demo program. It will be in: home/visualruby/visualruby_examples/treeview I've done lots of work on the program in the last few days. Will you test it for me? Thanks, Eric

Thanks for your patience...I can get it to work ... sort of... In the ListView Example (converted to TreeView), I can use GTK code to add a row to the tree parent = self.model.append(nil) parent[0] = VR::CalendarCol.new DateTime.new(2000, 1, 15, 7, 23, 0) parent[1] = DataObject.new("Bob Johnson", "18458 S Beauford St.", ... parent[2] = VR::TextCol.new "Does this Work?\n\n- Umberto Eco" If I copy the add_row method into the Example Code and change hash to *args I can also get it to work: def add_row(parent, *args) <-hash changed to *args child = model.append(parent) (0..args.size-1).each { |i| child[i] = args[i] } return child end parent = add_row(nil) parent[0] = VR::CalendarCol.new DateTime.new(2000, 1, 15, 7, 23, 0) parent[1] = DataObject.new("Bob Johnson", "18458 S Beauford St." ... parent[2] = VR::TextCol.new "Does this Work?\n\n- Umberto Eco" otherwise I get the error that args doesn't exist... ViewCommon.rb:132:in `method_missing': undefined local variable or method `args' for #<ListViewObjectsGUI:04EE4FA8 ptr=02DFA160> (NameError) I am fine with using the Gtk::TreeView append, I was just trying to understand what a "pure" VR::TreeView would look like. Thanks, Greg

It's available now. Do this: $gem install visualruby You should get vr v1.0.7 or later and vrlib v1.0.4 or later.

I get an error on the gem install(file 'lib' not found) But that is probably related to rdoc, and may have been there before. When I run VR though I get an error:Failed to open file './glade/VR_Main.glade': No such file or directory -- Warning with vrlib-0.0.33 --C:\Users\ghh\visualruby>vr --C:/Ruby193/lib/ruby/gems/1.9.1/gems/vrlib-0.0.33/lib/GladeGUI.rb: line --127 -- Gtk-WARNING **:Unknown property: GtkMenu.ubuntu-local C:\Users\ghh\visualruby> C:\Users\ghh\visualruby>gem install visualruby Fetching: vrlib-1.0.12.gem (100%) Fetching: visualruby-1.0.12.gem (100%) Successfully installed vrlib-1.0.12 Successfully installed visualruby-1.0.12 2 gems installed Installing ri documentation for vrlib-1.0.12...

Hi Greg: Those warnings aren't a problem. I got the lib warning before, I think it was related to rdoc. The ubuntu-local can be ignored. Glade spits out a big mess of warnings too. E

I tried the TreeView example, and It worked just fine. Thanks for all the work. Greg

Hi Greg: Thanks for finding that issue with the treeview. I had overlooked updating that code. Please let me know anything else you find. I may be short on time soon, but I will try to help. Eric
