Where I come from calling somebody a son of a bitch constitutes losing
your temper.

I just think we have to continue to build bridges between fully-sighted
developers and us.  often sighted developers, like other sighted folks,
don't ever think about sight-loss.  Not because they are fundamentally
uncaring but just because it never registers on their radar.

And calling sighted developers names and losing our temper, throwing our
toys out of the pram will not result in anybody being encouraged to go
the extra mile for us.

Just as constantly bleating about non-accessibility issues on the
mailing lists and forums of the XYZ desktop will not endear our cause to
people already struggling with lengthy bug lists.

Hello,
This is turning into a verry interesting discussion.
A little while ago I was having similar discussion at gnome
accessibility email list with Alejandro Pińeiro Iglesias. My use case
is a bit different and unfortunatelly I am progressing really slowly.
But anyway here is the last message on this.
https://mail.gnome.org/archives/gnome-accessibility-list/2014-July/msg00017.html

I am so far only targetting latest gtk version and the app I am
playing with is coded in vala.
I've managed to subclass GTKRendererCellAccessible in order to provide
a working accessible name for a treeview column which is rendered
using so called CellRenderer. The approach here reminds me a bit of
how list view rows are owner drawn on windows.() Now I am going to
look if I can make the text provided via get_name method reading by
character, word and possibly other units using flat review. I suspect
I need to implement so called ATKText methods on my subclass however I
haven't yet figured that out plus I am afraid of issues related to
working with screen coordinates etc. Amd unfortunatelly I am real noob
asking for hints every so often so up to now I feel rather stupid
causing more issues than I might be able to solve.

Greetings

Peter

Hi Mike,

Unfortunately, we don't really have a good tutorial for building
custom atk classes (I thought there was one around somewhere, but now
I can't find it, and it would be outdated anyhow). My suggestion
would be to look through gtk's accessibility code (in gtk/a11y for
gtk 3) and look at the atk documentation as a reference:

https://developer.gnome.org/atk/unstable/

For the stable gtk+ sources:
ftp://ftp.gnome.org/pub/gnome/sources/gtk+/3.12

If you only need to support gtk 3.8 or later, then you can derive
your classes from the relevant Gtk*Accessible classes and call
gtk_widget_class_set_accessible_type in the custom widget's class
init function. If you also need to support earlier versions of gtk,
then it is a bit of a mess, and your best bet is probably to override
get_accessible in the class init function and create a base class
adapted from, say, GtkWidgetAccessible. For an example of how to do
this, you could look at my patch on
https://bugzilla.gnome.org/show_bug.cgi?id=669441 (the patch in
comment 7, not the much cleaner patch in comment 4, but the latter is
a good example if you only need to support gtk+ 3.8 and later). One
option might be to encapsulate the accessibility code with #if
GTK_CHECK_VERSION(3.8.0), depending on whether it's important to make
it work for gtk 2 as well.

Feel free to write if you have other questions. Sorry for not being
able to suggest anything more straight-forward in terms of
documentation, but, anyway, it would be good for more people to
understand how all of this works.

Thanks,
-Mike

He also said that if I add atk accessibility to it he will
incorporate
the changes.

But as I don't currently know how to do this, it is likely to take
me a
while.

If anybody can point me at atk tutorials and tips I'd like to have
a go
as I am a big fan of SciTE on Windows.

Mike
