I have a family of application which must support the change of language
on the fly. This we're doing since a lot of time, and everything works
just fine.
Now I face the problem of providing support also for right to left
languages, such as Arabic.
Application.BidiMode can be set true or false, depending on the selected
language, and that's ok, but setting up the proper alignment is rather
cumbersome, IMO.
You can use flipchildren() but after that I didn't find a way to detect
if control alignment is the original one at design time, or it has been
flipped. One should add a flag to each form in order to keep track of
the flipping history.
A more general solution to properly support right to left languages and
layouts, IMHO, would be to add an isFlipped property to Tcontrol, which
is toggled each time the control is flipped. It wouldn't be Delphi
compatible, but also flipchildren() isn't Delphi compatible, so this
shouldn't be an issue.
However, before submitting a patch I'd like to know if I'm missing
something, and the solution is already there.
