multiple selection and drag-n-drop

[Allin Cottrell <cottrell wfu edu>]

I suppose somebody else must have come across this issue -- and if 
so I'd be grateful for any ideas.

I have a treeview in which GTK_SELECTION_MULTIPLE is enabled.  
And there's a meaning attached to dragging elements from this 
treeview to another window.  

The design problem is that if the user has selected multiple 
elements in the treeview (using shift- or ctrl-click), and then 
she presses the mouse button to start a drag, that press undoes 
the multiple selection, and only the element directly under the 
mouse pointer actually gets dragged.  Is there a "standard" way of 
handling this?
