[orca-list] Accessible labels in editable fields

[Luciano de Souza <luchyanus gmail com>]

Hi listers,

Using Lua and the graphical library IUP, I have created a dialog with 
some buttons and fields. In Linux, IUP is an abstraction of GTK driver, 
so it's entirely compatible with Orca.

Buttons, lists, radio buttons, menus, combos  are all satisfactorily 
read. However, I have some problem with editable fields.

When I focuse on a editable field, Orca says "edit", but it doesn't read 
the respective label placed on the left.

As As far as I know, screen readers, in Linux or in Windows, doesn't 
read automatically the labels when focusing a editable field. The 
solution in Windows seems to be MSAA and in Linux ATK.

Perhaps, the solution for my problem is ATK. I don't know where ATK 
routines are placed. Perhaps, ATK is a set of dynamic libraries and I 
need to call its functions like a DLL in Windows or a SO in Linux.

I don't know. Even the most basic principles of ATK are unknown for me. 
I presume I don't need a deep knowledge of ATK. What I want to do is 
only to become readable a label, when focusing a editable field. So I 
ask when can I get information how to do this specific routine? This is 
the single change I need to do in order to make my dialogs accessible.

Well, the first approach is really ATK. However, depending on Orca 
features, perhaps, ATK is not required. With JAWS, if a label is not 
read, we can open a options dialog and configure a custom label. Having 
saved this label, JAWS is able to interprete correctly the relationship 
between the editable field and its label. Has Orca something like that? 
Can we label fields, storing these definitions in a script file. If the 
answer is "yes", when an application is developed, to make it 
accessible, perhaps, in the pack, a Orca script file can be reliesed, 
assuring the desirable accessiblity.

What do you suggest to whom wants to develop applications in Linux with 
accessible editable fields?

I have never studied something about ATK, but I heard it can be a 
possible way. Regarding I want only to make an editable field 
accessible, I wish the simpler solution.

Regards,

Luciano
