I have an odd issue. I'm adding some custom script on top of the latest
Flex/Flash scripts to get a flex application to do some special stuff in
IE. My flex app essentially displays a "document". It has a navigation
area which allows the user to change to another "document". I wrote
some scripts to sense that change and when that happens I want jaws to
say the new document. Here's the odd part. I have the window handle to
the flash window within IE. If I do something like the following,
MoveToWindow(hwnd)
JawsPageUp()
JawsHome()
SayAll()
Or just
SayWindow(hwnd)
It does two things I can't explain. First, it reads the stuff from my
app in "screen order" (i.e., top to bottom, left to right), not in the
MSAA order I see the stuff in the MS Accessibility Explorer. Also, and
this is worse, it's saying a garbled mess of stuff from all the
documents I loaded since then mix in with the current one. It's as if
it's buffering stuff based on screen location and it's not ever getting
rid of it. I used the AccEvent program to check that things were
getting destroyed and it seems they are, but for some reason, Jaws wants
to read them.
If, however, I use this code
JawsTopOfFile()
SayAll()
Then jaws reads everything as expected (no old document info). However,
it says the entire IE window contents which I don't really want. But
the order is fine.
Is there something I'm doing wrong? I'm a seasoned experienced
programmer, but I'm new to Jaws scripts so any technical information or
background would be greatly appreciated. So far, I read both the basic
scripting manual and most of the FSDN manual, and to be honest, I'm
learning the most by reading through the scripts that were delivered
with jaws. If anyone knows any other places to get good technical info,
that would be great.
Thanks,
Mark
