Re: inaccessible treeviews and tables

[Peter Vágner <pvdeejay gmail com>]

Hello,
Okay I am not going to emit more signals now unless someone will detect 
unexpected behaviour.
As for the context menu issue, the context menu is there, it opens when 
clicking using the right mouse button. However other than using orca's 
features to simulate a right click there is no way on how to popup that 
using keyboard only. Additionally I think providing keyboardaccess to 
popup menus is good practice and even some sighted people are used to it 
so I would like to do that if it's within my abilities.

Oh sorry and I have found out another bit I am missing. While browsing 
the screen using flat review my cells are represented as single 
characters only. So I have no way on how to read it word by word or even 
letter by letter using flat review. I guess I need to implement ATKText 
interface similar way TexCellRenderer does it. What is not obvious to me 
is do I need yet another object or do I just implement methods such as 
get_text, get_character_at_offset etc on my accessible? Isn't there some 
default implementation to inherit from?

Greetings

Peter
