编译后提示Configuration unchanged, skipping QMake step.Starting: E:/Qt/mingw/bin/mingw32-make.exe debug -w mingw32-make: Entering directory `D:/Documents/Qt/Calculator'E:/Qt/mingw/bin/mingw32-make -f Makefile.Debugmingw32-make[1]: Entering directory `D:/Documents/Qt/Calculator'mingw32-make[1]: Nothing to be done for `first'.mingw32-make[1]: Leaving directory `D:/Documents/Qt/Calculator'mingw32-make: Leaving directory `D:/Documents/Qt/Calculator'Exited with code 0.窗口闪了一下就消失了，花了几天也不知道哪里出错，帮帮忙！！！！！！！
