原创 RTTI symbol not found for class ‘QWidget‘

属性，WA_DeleteOnClose的作用是在窗口关闭时，调用析构函数销毁此窗（QWidget关闭时默认是隐藏的），所以，我先关闭d窗口，实际的d窗口已经被销毁，然后我在关闭主窗口，主窗口会在调用d窗口的销毁函数，但是此时d窗口已经被销毁，所以会提示找不到QWidget。这样，主窗口在关闭时不会再调用d的析构函数。这里面涉及到一个知识点就是，在父窗口的对象，当父窗口销毁时，其子窗口也会销毁。首先，导致这个问题的原因是找不到QWidget符号，在QWidget派生类里设置。关闭主窗口提示段错误。

原创使用AllocConsole在Win32窗口(GUI)程序中调用控制台调试输出

众所周知，Win32GUI程序默认不能使用调试窗口打印日志信息，那么，如何方便地在Win32GUI程序中使用控制台进行调试输出？答案如题：AllocConsole函数和C-Runtime的freopen函数。其中"CONOUT$"是指代当前console的特殊字符串，"w"表明以written模式打开这个console，stdout指代标准输出流。可重定向的流有：标准输入流、标准输出流或者标准错误流。AllocConsole函数的功能是为当前的窗口程序申请一个Console窗口，其原型为。
