Jeff,

While I generally agree with your criticism concerning the current 
development state of the treeview widget, I would have a quite serious 
problem if treeview wouldn't be integrated into the core.  The reason is 
that in the tile-enabled version of Tablelist I make use of some 
treeview-related elements, like Treeheading.border and Treeheading.cell. 
  Not having access to these elements would simply make it impossible 
for the Tablelist_tile package to work with Tk 8.5.  Currently, 
Tablelist_tile is the only multi-column listbox with tile support, and a 
lot of people intend to keep using it with Tk 8.5.

Also, your intention (decision?) to exclude treeview from the core 
doesn't take into account that there are quite a few people who already 
use treeview (in spite of its relatively early development state). 
After all, this wouldn't be the first widget in the core whose early 
versions are not yet quite satisfactory.

With treectrl, the situation is different.  This widget has always been 
a separate package, and from the programmer's point of view it makes no 
difference if it is merged into the core or not.

Please, think about these arguments and don't exclude treeview from the 
core!

Thanks,
Csaba
