alsalam 3ala man itaba3 al huda -
hope everyone is doing well. i have been stuck for a while on this
issue
and was wondering if anyone could suggest how to get this to work. i am
trying to write a tajweed highlighting engine... in order to do so, i
need to
be able to color certain letters in an ayah a different color.
the problem i am having is getting this to properly render in gtk.
i've tried two different approaches:
1. making two identical TextTags with nothing differing except the
colors,
2. playing around with pango_parse_markup() and, for instance,
GtkLabels to
see if i could get anything to work.
with the first, i had total failure - the letters would come out
separated [ie the shaping
would break].
with the second, it depends on what i did - if, for instance, i just
did color span of the
first half the string to be blue and that's it, it appeared to
perhaps work fine [i say it
"appeared to work fine" b/c at that size, its hard to really tell
whether they are two
separate letters or are connected to each other, but they seem
connected but am not
totally sure on that] -- but when i tried making the font larger, you
could clearly see shaping broken.
i tried to email owen and ask him, and his response a few months ago
was that it was
working as far as he knew and if i could write a c demo showing it to
submit a bug to
bugzilla - i've done so recently and emailed him, but i take it he's
really busy and so
hasn't gotten a chance to write back. in addition, ppl on the gtk-
app-devel list didn't
answer either.
if anyone can give me any sort of tip would be greatly appreciated.
thanks,
-ahmed
