[Xerte] How to disable the Tab key as the "Accessablility" key?

Tue Aug 4 18:52:35 BST 2009

I've been doing a lot of searching and experimenting, but so far, all
I've been able to come up with is disabling _focusrect. Apparently, you
can't change the color of _focusrect (at least, not globally) in AS2.
AS3 does provides a way to do so.

I've also tried to disable _focusrect, but enable it for buttons (I
tried Button._focusrect = true; and Button.Prototype._focusrect =
true;), but that doesn't do anything. You can tab and activate a button
with the space bar, but you never know what button has focus. The
default framework interface buttons don't seem to respond to the
keyboard when _focusrect is false. 

I'm using the button.swf component for my buttons, so, just for grins, I
tried _level1.Button.Prototype._focusrect = true (with and without the
keyword Prototype), but still don't get the focus rectangle around
buttons. So it looks like it's either always on or always off. I think I
will go through and add onKeyDown events for all my 'Next' buttons. That
would provide keyboard navigation without guessing where the focus is. I
don't display the Next buttons until it's time to move to the next page
anyway.

Thanks for the suggestions.

Paul

global.setstyle might allow you to change colour as an alternative

This works:

_level0._focusrect = false;

Strange how there sometimes is a lengthy time-delay between messages. My
"I got it" message arrived in my inbox 10 minutes before the message
below, which was sent 45 minutes earlier. Must of taken the long way
around the earth ...

Apparently there might be something in global.setStyle?

Patrick, your email did make it. I just wasn't clear on what I should
do. I am having success with iconID.tabEnabled=false to get rid of the
yellow border around text and graphics on individual icons (I'll leave
interactions alone). So thanks for that! I was hoping there was
something global I could do ...

Dave, _global._focusrect = false; looked promising, but not having any
luck getting that to work (I also tried rootIcon._focusrect). Too bad,
it's that focus rectangle that I really want to get rid of. Or just
change the color. Maybe I'll post something to the AWARE/eLearning
listserv. Maybe Jason Merrill will know; he seems to be very Flash
savvy.

Thanks for all the help!
