[PyKDE] Re: [PyQt] Problem with generated pyuic code: QSizePolicy()

[Don]

OK, I went back and read all the posts on this issue that I neglected to 
read before I posted this.

One question remains: What version of PyQt (or, is it part of Eric?) has 
the version of pyuic that will generate code that works with SIP 4.2 
(that is, it generates enums rather than integers for the QSizePolicy 
arguments)?

I don't have the luxury of specifying what version of SIP is installed 
on a system for my code to work. I certainly cannot count on a "hacked" 
version that turns off the enum checking. Therefore, I assume that 
passing the enums is the safest way to assure that it works "across the 
board"?

Thanks,

Don
