Nested TreeView

Hello all,

Is it possible to have nested TreeViews/TreeStores? I’m trying to
extend RSQLiteGUI to display relational associations and I’m wondering
how I can do this with TreeView…


Thanks!
Bryan

Did you see ‘Tree View/Tree Store’ sample in
gtk/sample/gtk-demo/main.rb sample program? Is it what you
want?

Thanks,

Hi Kou,

Wow, I did not know that demo existed… that will be very useful to me
in the future, thanks! Now, to answer your question: The TreeStore
example in the demo is not exactly what I was looking for. I’d like to
have nested TreeStores if possible. So, for example, let’s say I have a
table in a database that has a column for its id, a column for its name,
and a column for its value. Then lets say I have another table that has
a column for its id, a column for the id of the row in the other table
it belongs to, its name, and its value. Thus the second table belongs
to the first table, and the first table has many second tables. In the
TreeStore, if the first table has some rows in the second table that
belong to it, I’d like to be able to expand it out so that a whole new
TreeStore is shown for the rows in the second table. Very similar to
what the ActiveScaffold Ruby on Rails plugin does if you’ve ever seen
that demo.


Thanks!
Bryan

The demos helped me a LOT. At this point I want to chime in and express
my personal thanks to everyone who helped create these demos. They are
very useful.
