In fact no, it's a bug of cursorX and hence the cursor position is wrong
as well, even without selection. So the selection is just a consequence
of that.
Yeah, it's a different situation than what I was originally speaking of.
The original situation is already solved with your latest patches, this
one you point out is not; but as you say, it's not really a selection bug...
So, what should we do now? I can fix either: I can make the getFont
method to behave like the bidi algorithm, or I can make the bidi
algorithm to handle spaces like normal characters, or I can make the
cursorX method to compute the right position according to the bidi
algorithm (at the moment its logic uses both, hence the bug), hence
the bug would be gone, but we keep the difference between GUI and
output. Opinions?
Well, I'm still not sure, I'd like to hear more opinions from Bidi
users...
I think my inclination is this: we "ignore" the language of spaces,
and make them behave according to the bidi algorithm (or even better,
first decide how they should be treated, according to the bidi
algorithm, and then set their language accordingly --- would that be
possible?
getFont must be tweaked a bit to use the outer font for space at the
end/start of RTL segments. It's possible and probably not very hard.
The advantage is this: that would also make them show up on the screen
as they are treated internally, and more importantly: would make latex
treat them correctly). I bridle at the fact that we are forcing
something on the user, but OTOH I can't think of any situation where
the user would want to force different behavior. And the alternative
would also require the lyx2lyx changes...
Will try it out....
Thanks, that would be great. I won't be online for the next day or so,
so I won't be able to provide feedback right away (just in case you're
planning to try it now...)
But again, I want opinions from other Bidi users (and any other
developers, too).
Don't know. Most people don't care about Bidi, maybe on the user list
might be more fruitful. One has to create a few pictures which show the
different possible implementations.
I'll try to do explain the issue as clearly as possible, and then post
to the users' list. But that'll also be only in a few days...
Thanks, Stefan, for looking at this...
