Hide focus border

[Hannes Mayr <hannes mayr indunet it>]

Hello,

is there a way to hide or to make invisible the dotted focus border?
I'm developing an application for a small display on an embedded board 
and there is no mouse pointer, just a keyboard with several buttons to 
move the selection up and down in a treeview. If I set the selection to 
the first row of the treeview (with gtk_tree_view_set_cursor) the focus 
border is on the first column. What I want to achieve is to have an 
entire selection of the first row without that focus border.
Maybe someone can give me a hint.


Thanks,
Hannes
