[Pharo-project] Squeak on iPad (2)
by Torsten Bergmann June 21, 2010

June 21, 2010

More here: http://croquetweak.blogspot.com/2010/06/squeak-etoys-on-ipad.html "Morphic was designed to handle multiple "hands" (pointing devices) from the beginning" I hope we didnt remove that while cleaning morphic, so Pharo could also be made multitouch-aware.

Hi Bob and welcome. There are two possibiities I know to write/communicate to C: - The FFI plugin is intended to call external libraries from Smalltalk http://wiki.squeak.org/squeak/1414 http://forum.world.st/FFI-Documentation-td2225148.html#a2225148 - Write your own VM primitives http://wiki.squeak.org/squeak/356 http://wiki.squeak.org/squeak/3336 http://wiki.squeak.org/squeak/6102 Probably there are much more links, but maybe this is enough to remember you what you used.

[Pharo-project] OBSystemBrowser and class comments
by Adrien BARREAU June 21, 2010

June 21, 2010

Hello all, I'm writing some class comment for Citezen. But I think something is strange: when I type something on my keyboard, there are 1 or 2 secondes of latent period before it display it on the screen. I don't know if it has already been signaled.
