You can adjust column widths from the program with:

	$tv column $columnid -width $pixels

Unfortunately there's no easy way (at present) to automatically 
calculate preferred column widths.  (Suggestions welcome here.)

The treeview's requested width will be the sum of the visible
column widths.  If the actual width ends up larger or smaller than 
this, the difference is added to or subtracted from the last column,
down to a minimum width.  If necessary, subsequent columns are 
"squeezed" from right to left.  I plan to replace this algorithm
with the one the [ttk::paned] widget uses, that seems to work
better.
