How to compile plugins/qwindows with mingw enviroment on win7 system?

[dhuta]

Hi,
i just open the src code .pro with qtcreator, but i cannot get a qwindows.dll though there is no compile error; but i only get some .o files and severial .moc files. I made some changes for qwindows src code so that qwindows can not sucessfully find and use MS's system fonts by default when its font engine cannot find the specified string to be rendered with certein font file. I just simply change it's hard-coded path like registery and MS's system font path. In fact, i don't know if this can work.

Is there anybody has an idea?
