TreeView + Updating list on mouse-click of header

Hi there,

I am using TreeView to display list store data

This works fine.

However, I want that, if you click on the header,
the list store to update and sort alphabetically.

My problem is - there seems to be no event possible
when you click on that header?

Example of my widget:


Name Age Profession


joe | 51 | C# Coder
tim | 31 | Python Coder
pete | 25 | Ruby C.
| |
| |
| |

And I want to update the listings whenever
someone clicks on “Age” or “Profession”
in that header, inserted via

tree_view.insert_column(-1, ‘Age’, renderer, :text => 1)
tree_view.insert_column(-1, ‘Profession’, renderer, :text => 2)

You can’t. Use the following way instead of your way:

column = Gtk::TreeViewColumn.new('Age, renderer, :text => 1)
column.set_sort_column_id(1)
tree_view.append_column(column)
