[PythonCE] Qt-wince
I saw that Trolltech is releasing a WinCE version of Qt (there is a preview available on their web site). Do you know if a PyQt port could be considered on such plateform? Does anyone here already have looked this way? -- Frédéric ___ PythonCE mailing list PythonCE@python.org http://mail.python.org/mailman/listinfo/pythonce
[PythonCE] Threads / network
Hi, 1) Yes, the thread and threading module are portable wrappers around the os threading facilities. This means they suffer from the same limitation of the os, I can remember there's about max 32 concurrent threads possible on wince (vs ~1000 on the desktop) 2) Yes, all you have to do is to bind your server, or connect your socket to the loopback interface via the ip 127.0.0.1 Regards, Alexandre ___ PythonCE mailing list PythonCE@python.org http://mail.python.org/mailman/listinfo/pythonce

[PythonCE] Qt-wince
Hi, A PyQt port should be feasible, but I'm afraid we'll end up with the same problems as wxpython port regarding high memory usage: Wince kernel has a very tight virtual address space in which dll are adressed (about 32MB), this means passed a certain point, dll could not be loaded. Also the address of the dll must be aligned on a 32k boundary (I'm unsure if it's the exact value), meaning it's better to have one big dll than many little for the same code size. Basically, SIP and SWIG wrappers are a lot of dlls themselves. I do not want to discourage anyone willing to port PyQt, but please consider these two points: - Wrap only the minimal gui classes to reduce code size - Produce only one dll for the wrappers, and better, link statically the wrappers with the Qt library Regards, Alexandre ___ PythonCE mailing list PythonCE@python.org http://mail.python.org/mailman/listinfo/pythonce
