The Qt port is still a bit experimental and may crash sometimes, but seems to work well enough for some poeple to use it. > Also, what programming languages in Haiku already have (working) Qt > bindings? In Qt, as in Haiku, the preferred language is C++. There might be others choices for Qt, but I don't recommend them. > > @pulkomandy: does the Qt-based Nagaina text engine support > bidirectionality, i.e. RTL and LTR text on the *same* line? (The > screenshot only shows Arabic text) I don't know, Qt does not use the OS support in any way and does its own thing. -- Adrien.
