在Qt开发中遇到“error: reference to non-static member function must be called”错误通常表明你尝试以错误的方式引用或调用非静态成员函数。下面我将分点解释这个错误,并提供解决方案。 1. 解释错误信息的含义 这个错误信息意味着你尝试使用非静态成员函数的方式不正确。在C++中,非静态成员函数是依赖于类的实例(...
错误:Char 26: fatal error: reference to non-static member function must be called 主要原因是我使用了函数指针,而函数指针所指函数须得是静态才行 classSolution{public:vector<int>exchange(vector<int>& nums){returnReOrder(nums,iseven); }vector<int>ReOrder(vector<int>& nums,bool(*func)(int)){ ....
编译器会给类的非静态成员函数添加一个this参数。 int square(int num) { return num * num; } class Hehe{ public: int square(int num) { return num * num; } }; int main() { int
Qt开发,一行代码报错: reference to non-static member function must be called; did you mean to call it with no arguments? 代码: if(tbxD.toPlainText().trimmed().length==0) { ... } if(tbxM.toPlainText().trimmed().length==0) { ... } if(tbxS.toPlainText().trimmed().length==0)...

Within the body of a non-static member function ofX, any unqualified-id that resolves to a static member, an enumerator or a nested type ofXor of a base class ofX, is transformed to the corresponding qualified-id: structS{staticintn;voidf();};voidS::f(){n=1;// transformed to S::...
