[g-a-devel] question about GAIL TreeView cell actions

[Mike Gorse <mgorse alum wpi edu>]

Hi all,

I've noticed that gailcell.c defines an "expand or contract" action when a 
tree view cell has other cells under it.  There is a function called 
gail_cell_type_add_action_interface which adds the action interface. 
However, it is only called by gailbooleancell.c, which is used for toggle 
cell renderers.  So one cannot expand or contract a row using an action if 
there is no cell with a toggle renderer.  I wasn't sure if this was a bug 
or not--it looked like it had been coded that way intentionally--but it 
isn't what I would expect, and it would be helpful if I could perform an 
action to expand or contract any cell that is expandable.  Does anyone 
have any thoughts or know why the code is designed the way it is?

Thanks,
-Mike G-
