Hi Ian
I could try it but would be looking at the the key-up. For you will note
in my old event key char, or OnKey function I was looking ahead. That is OK
and it worked with the elif list, but the textctrl edit field can have
pointers that do not point to the actual text position.
When reading on the subject, studying what methods textctrl had, I chose
to use them instead for an easier, less code check. It also needed the
key-up event so the pointer moves after releasing the key and by the time I
catch the event the pointer is where it is to be and I just get the pointers
and I am done.
So, I added the onkey_up function to do just that. The function is much
smaller and less time consuming except the check for word forward and back.
There I needed to go and fetch all within a word to say the word.
By doing this I use the key code to decide, which in all cases it is
just the point in the line. Where the entire line read for up and down
requires only to know the position and translating that using the built in
function to convert to line and col, then the the entire line is loaded with
another built in function and I get my line.
The nice part about this is that I do check for end of line chars, which
may vary with platform, In other words, single cr command, 13, for all
others are lf, or 10 for line feed.
When even going word forward and back it actually announces the end of
line because it stops there and makes it all nicer.
Anyway, thanks for the input, for trying to understand all the built in
functions can be a little bit time consuming. But the more I write the
easier it gets.
I am using the wxpython for the buttons and frames are standard format,
and my screen reader reads them as if it were a regular window. Now games
are a different thing, for the people I write it to, the screen images is
not that important.
The Pygame window is seen by screen readers a just a single line just
below the title bar.
I have added another engine to my speech and it also uses the Sapi 4
voices and will load up to 28 voices. For your Vista to read it I think you
have to fool Vista. But that has to be done before loading the speech
engines. Sapi 4 and 5 do work together but only in XP, not Vista.

I use pygame.key.get_pressed(). I usually use the state of the input
in question rather than deal with events. My generic input function
looks like:
def GetInput():
key = pygame.key.get_pressed()
for event in pygame.event.get():
if event.type == QUIT or (event.type == KEYDOWN and event.key
== K_ESCAPE):
pygame.quit(); sys.exit()
For your purposes, I now add:
if event.type == KEYDOWN:
text.append(event.key.name)
mpress = pygame.mouse.get_pressed()
mpos = pygame.mouse.get_pos()
All untested (on vaction without a laptop); hope it works!
Good luck,
Ian
