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)...
std::cout<<"Hello from myFunction!"<<std::endl; } }; intmain(){ // Attempting to call a non-static member function without an instance. MyClass::myFunction();// This will cause the error return0; } Corrected Code: You need to create an instance ofMyClassand then callmyFunction(...
How would I go about to fix this error? The error occurs at line 60 with the message "error: reference to non-static member function must be called; did you mean to call it with no arguments?". 1 2 3 4 5 6 7 8 9 10
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::...
Cannot make a static reference to the non-static method的解决方法,报错原因:在一个类中写了一个publicStringgetContent()方法和一个main()方法,getContent()方法中包含了getClass()方法,在main()方法中直接调用了getContent()就出现如题的错误。这样一样解决方法:
意思是你访问某个类的某个非静态成员的时候没有指定对象。正确引用非静态数据成员的语法是： 对象名.成员名 或者 对象指针->成员名 我估计你大概是定义了一个静态成员函数，并且在该函数内部引用了一个非静态成员，但是你引用的时候没有指定对象，所以编译器报错。
