[Qt-interest] a question about QLibrary

[Eric Clark]

Yifei,

Did you figure this out? I left yesterday before I heard back from you. We have dealt with this type of issue in our application and came up with a solution. I could probably help you out a lot if I knew a little more about what exactly you are trying to do. Let me know if you figured it out already. If you haven't, I will send you some more information.

Thanks,
Eric
