[Blindmath] Using Java Draw2D in an SWT GUI

Well, technically speaking WebOS had the potential to be the most accessible, and they actually didn't need to architect
accessibility into it. someone could simply have written a web delivered screen reader for it that ran in its own JavaScript thread,
and you'd be done.

So, to add to Ken's point, if you don't include accessibility in the development process, then use 100% completely standard
technologies that are already accessible, which is actually what WebOS did.

Well Apple is more the norm now day if you look around.  Just try windows 8.
How about Nokia phones even though they are dying.  How about .net now true
it's not self voicing but it's a far cry from Win32 the point is just
because accessibility is not first on their list I am pretty happy it is in
their development list now rather than being left out totally as for example
HP did with Web OS.  The good thing is developers are starting to see that
what makes a good accessible product also makes a good usable product. .

The iPhone is an excellent example of my point.  I have an iPhone and admit
that 
Apple has done a pretty good job of adding accessibility where it didn't
exist before.  Unfortunately very few app vendors have followed suit.
Better original design could have made accessible app programming more or
less automatic.  Now I have to rely on the good will of app makers and most
don't even seem to know about accessibility.

I'm there if there's anything I can do to help get accessibility right in
SWT or JavaFX. While it is sad that accessibility historically gets put in
as an afterthought it's even sadder that in every one of the cases you cite
that it has generally been done badly or incompletely. Ken and I both have
recent experience with the very bad accessibility framework in Android. They
may get it right eventually. Apple has done somewhat better but the
experience is still what I would term as tedious, especially on Mac OS. It's
getting better but only slowly. Microsoft, well they were first to make
accessibility a part of the UI but dropped the ball at some point and are
now playing catch up. Gnome? Great ideas but the reality has fallen far
short of the vision.

Every one of the efforts mentioned has included some excellent ideas and it
should be possible now to use them and get it right at last. There are a lot
of great blind programmers out there and some very savvy users. I'd
encourage Oracle and others in the Java community to enlist some of them and
invest in making the vision a reality.

One principle, and this is very important, is that efforts need to continue
to make it more trouble for application developers to leave out
accessibility features than to include them. I'm not sure exactly how to
make this happen above what's already been tried but again, it is important
because it is the usability of the apps and not the accessibility features
of the tool kit that is key.

Off my soap box now. :)

Keith


We need to be grateful that the effort is made at all and do what we can to
encourage it to be done sooner in the development process and that it be
done right. One key aspect, and I don't know exactly how to do this, is that
developers of UI tool kits need to make it more beneficial for application
developers to use the accessibility services than it is to work around them.
Not a new thought I know but so far it seems like apps still come out with
UI's that somehow circumvent accessibility features.

Well while I agree with you on one hand I have to point out IPhones did not
have accessibility till version IOS 3 and people seem to forget that when
they scream about Android and Windows phones.  They seem to forget that Mac
operating system didn't build in access till version 10 pretty much.  So
Let's dial back the rederict that it can't be built in and work with them to
make sure it is built in right.  I feel your pain but I also understand that
the market doesn't always allow what we want to happen.  Even if better
planning would make this all easier for everyone. 

Note that we are in a new age where companies are starting to understand
that usability and accessibility makes their products better.  Maybe it
takes a couple of versions to get there but that is a far cry from how long
it has taken in the past.  We are getting to the point that new software
comes out and it's just accessible that's great and it should be cheered on
but maybe we need to work more with these companies than to set them to the
torch.

Just my dime.

So JavaFX plans to "add accessibility" in version 3.  You can tell the
developers from me that there is no such thing as "adding accessibility".
Others have tried and failed.  Take PDF for example.  Either software is
developed to be accessible or it isn't.  This is just an insult, and Oracle
should be punished severely.  Maybe they are not aware that both the public
and the lawyers are now insisting that new electronic
information/softwaredevelopments be made accessible "if feasible".  Well it
is feasible.

Do I sound angry?

Subject: Re: [Blindmath] Using Java Draw2D in an SWT GUI

We created SWT because, at the time, Swing was years away from being
production-quality, and we needed to ship product.
I tripped over this 2002 post recently. It summarizes the climate of the
time:  
http://www.mail-archive.com/jug-discussion@tucson-jug.org/msg00355.html
(I do not know who the "undisclosed source close to IBM" is, but much of
what he says seems accurate).
Please, I am not dredging up the past here to be inflammatory, merely to
help explain why there are things that I cannot fix.

On the plus side, the designer of SWT is now working at Oracle, so future
interop will improve.
However, the improvements won't be in AWT/Swing - they will be in JavaFX.
Oracle recommends that, moving forward, people use JavaFX to build Java
GUIs.
The good news is that JavaFX is new, current, designed for both desktop and
browser, has cool graphics, a whole bunch of groovy new controls, and all
controls can be css styled.
The bad news is that JavaFX is a whole new widget set, with its own event
model, layouts, and graphics system, and because it is new, some things are
not yet implemented, like Mac and Linux support (coming in FX 2.1 and 2.2),
and accessibility (promised in FX 3.0, which is currently due to ship
sometime around 2013Q4, if I am reading the roadmap correctly).
AWT/Swing have interop with JavaFX, but they are effectively deprecated, and
the problems inherent in the Swing threading model make interop complicated.
SWT and JavaFX both use the same threading model, and apparently SWT embeds
nicely in JavaFX and vice-versa.

So I think JavaFX might be the way you want to go, but it will be some time
before it is fully accessible (I believe) because JavaFX controls are custom
drawn, and all of the accessibility will need to be implemented from
scratch. I hope that they will fully integrate accessibility into JavaFX and
ship it with the JDK... they have surely taken some lessons from the Swing
accessibility problems regarding the difficulty of installing the JAB.

Here are some links:

that was just an accidental omission.) 9. JavaFX and SWT interoperability:

Michael has provided the answer to your question about the JAB.

I can create workarounds.

I can write complex code to make things work that don't fit together like
they should.

I can modify the code in textbooks to make it compatible with the SWT.

I can modify the code in existing libraries to make them compatible with the
SWT if the source code is available (which is what I am now being forced to
do to provide GUI accessibity).

However, the great promise of Java is the ability to use class libraries
written using standard Java libraries without a requirement to modify those
libraries. IBM and SWT have succeeded in breaking that promise. Therefore,
IBM should have named their new product IBMJava (or maybe Java#) to make it
clear that it is not Java. Once a naive programmer starts down the SWT
route, thinking that she is programming in Java, she has just excluded most
of the promise of Java from her programming product.

Being essentially incompatible with the JFrame class, the standard Image
class, and the standard Canvas class, to name just a few, IBM and SWT have
made it impossible to use most existing Java graphics libraries without
modification. The IBM versions of those classes aren't better, they are
simply different and incompatible with standard Java. And the SWT graphics
capability is, in my opinion, inferior to the Sun Graphic2D class.

That might be a good product strategy for IBM, but it is definitely not good
for the majority of Java programmers.
