Re: [g-a-devel] Slider: Text has weird chars

== How did you get the text? Through text interface?

I used the AccessibleText interface.  Distilling out the error checking,
my code looks something like this:

    if(Accessible_isText(aObject)) {
       AccessibileText *aText = Accessible_getText(aObject);
       int charCount = AccessibleText_getCharacterCount(aText);
       if(charCount == 0) return;
       char *actualText = AccessibleText_getText(aText, 0, charCount);
       ...

I'm testing an application that I wrote myself.  I'd be happy
to send it to you.

How did you get the text? Through text interface? If so maybe it comes
from Pango... Which application you are testing? I tried Totem but
didn't get the text.

Thanks,
