今天在使用Qt写一个C++函数模板的测试程序的时候,编译的时候,编译的时候出现如下错误: 错误描述为:在main函数中,进行函数max()重载时,出现(ambiguous)含糊的,不明确的;引起歧义的使用; 因为第一次遇到这种错误,写篇内容纪念一下吧。 测试代码如下: #include <iostream>usingnamespacestd; template<typename T>//t...

You can even define the lambda function as in-line code in the call to connect, like this: connect(button, &QPushButton::clicked, [=]() { qDebug() << "Slot is a lambda function."; }); Threads While not as comprehensive as the support in Qt, C++11 now has support for threads ...
