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 methodargs’ for #<ListViewObjectsGUI:04EE4FA8 ptr=02DFA160>
(NameError)
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.
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
otherwise I get the error that args doesn’t exist…
ViewCommon.rb:132:in method_missing': undefined local variable or methodargs’ 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
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

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.
