我试图将我的应用程序中某一页面的所有 GUI 封装在一个函数中，以便我的 mainFrame 函数更加干净，这样我就可以通过仅调用一个函数来创建整个 Gui，但是我收到了 C2064 错误当我尝试使 mainFrame 作为按钮的事件处理程序时，有人可以帮忙吗？下面我提供了我的脚本：

还有我的 MainFrame.h 文件：
#pragma once
#include <WX/WX.h>
#include <wx/scrolwin.h>
#include <iostream>
#include <iomanip>
#include <Windows.h>
class MainFrame : public wxFrame
{
public:
MainFrame(const wxString& title);
void StringEmptier(wxFocusEvent& event);
void CustomerInfoBTN(wxCommandEvent& event, wxTextCtrl* CustmeName, wxTextCtrl* CustmeGender, wxTextCtrl* CustmeAddress, wxTextCtrl* CustmeAge, wxTextCtrl* CustmeMobileNum, wxTextCtrl* CustmeCreditNum, wxTextCtrl* CustmeIdD);
private:
void OnPaint(wxPaintEvent& event);
};
class Customers {
public:
std::string Name{};
std::string Gender{};
std::string Address{};
int Age{};
int MobileNum{};
int CreditCardNum{};
int CustomerID{};
};
class Cabs {
};
class Booking {
};
class Charges {
};
来自 Visual Studio 输出终端的确切错误：

我尝试通过在调用函数时请求大型机的引用来设置 MainFrame 事件处理程序，但它只是导致弹出 C2064 错误
当您将指针传递给成员函数时，例如
StringEmptierthisthis CustomerName->Bind(wxEVT_SET_FOCUS, &MainFrame::StringEmptier);
实际上应该是
CustomerName->Bind(wxEVT_SET_FOCUS, &MainFrame::StringEmptier, this);
相反。
顺便说一句，当错误消息中直接有行号时，使用“反复试验”来查找有错误的行是很奇怪的。
