Re: [twsocket] ICS and Delphi XE2
There may be such an event system in FireMonkey, don't actually know. It seems Embarcadero bought KSDev earlier this year: http://www.ksdev.com/ and the feature page of VGScene may provide some hints about the capabilies of FireMonkey, although Embarcadero may have changed everything! http://www.ksdev.com/wiki/index.php?title=VGScene Angus -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Angus Robertson - Magenta Systems Ltd wrote: There may be such an event system in FireMonkey, don't actually know. But supporting ICS with FireMonkey and Mac OS-X is not simply a case of a few bug fixes and conditional compilation changes which is effectively all that is needed for 64-bit VCL support (and a massive effort from Arno testing it all!). Yes, I absolutely understand that. I'm as curious as you on what level event handling will be supported by FireMonkey :-) BTW: Thanks to the ICS team for their work on 64-bit VCL support!

Additionally ICS uses the message-based Windows non-blocking socket API. There doesn't exist something similiar on other platforms, at least not at such a low level AFAIK. Means non-blocking behavior had to be implemented using threads (as Windows implements that as well, under the hood) using the platform messaging/notification stuff available. The ICS for Kylix Angus mentioned isn't true xplat, though it made porting Windows ICS apps to Linux easier. That version will certainly run on MAC OSX/POSIX as well with just a few changes. However if we want a true cross platform ICS major parts would have to be rewritten from scratch which were a lot of work and porting existing code to such a ICSX certainly won't be a very simple task. -- Arno Garrels -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
