Double click on GtkTreeView header

["Ian King [ES]" <king eiffel com>]

Hi,

Is it possible to handle the double-click event when you click on the 
tree-column divider in the header, the usual behavior is that it will 
autosize the column header to the left.  I want to abstract the header 
from the tree view and use it for my own custom drawing implementation 
and handle events from the header that would normally go to the tree.

Thanks for your time
