问题：
I'm using Qt4 and C++ for making some programs in computer graphics.我正在使用 Qt4 和 C++ 来制作一些计算机图形程序。 I need to be able to print some variables in my console at run-time, not debugging, but cout doesn't seem to work even if I add the libraries.我需要能够在运行时在我的控制台中打印一些变量，而不是调试，但是即使我添加了库， cout似乎也不起作用。 Is there a way to do this?有没有办法做到这一点？
