Any other ideas maybe? imho all you need is the same as scale. you want a single global RTL or LTR (default is LTR) and then per object an api call to set this explicitly. the rest would be the job of something like elementary to just set it on everything (like it does with scale etc.). -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- The Rasterman (Carsten Haitzler) ras...@rasterman.com ------------------------------------------------------------------------------ Download new Adobe(R) Flash(R) Builder(TM) 4 The new Adobe(R) Flex(R) 4 and Flash(R) Builder(TM) 4 (formerly Flex(R) Builder(TM)) enable the development of rich applications that run across multiple browsers and platforms.
