如何为wxwidgets中的类创建的按钮添加命令？

#include <wx/wx.h>

// 定义命令标识符
enum
{
    CMD_BUTTON1 = wxID_HIGHEST + 1,
    CMD_BUTTON2,
    // 添加更多的命令标识符...
};

class MyButtonHandler : public wxEvtHandler
{
public:
    MyButtonHandler(wxWindow* parent)
        : m_parent(parent)
    {
        // 绑定按钮点击事件与命令处理函数
        m_parent->Bind(wxEVT_BUTTON, &MyButtonHandler::OnButtonClicked, this, CMD_BUTTON1);
        m_parent->Bind(wxEVT_BUTTON, &MyButtonHandler::OnButtonClicked, this, CMD_BUTTON2);
        // 绑定更多的按钮和命令...
    }

    void OnButtonClicked(wxCommandEvent& event)
    {
        int commandID = event.GetId();
        switch (commandID)
        {
            case CMD_BUTTON1:
                // 处理按钮1的命令
                break;
            case CMD_BUTTON2:
                // 处理按钮2的命令
                break;
            // 处理更多的按钮和命令...
        }
    }

private:
    wxWindow* m_parent;
};

class MyFrame : public wxFrame
{
public:
    MyFrame(const wxString& title)
        : wxFrame(NULL, wxID_ANY, title)
    {
        // 创建按钮
        wxButton* button1 = new wxButton(this, CMD_BUTTON1, "Button 1", wxPoint(10, 10));
        wxButton* button2 = new wxButton(this, CMD_BUTTON2, "Button 2", wxPoint(10, 50));
        // 创建更多的按钮...

        // 创建按钮处理器
        m_buttonHandler = new MyButtonHandler(this);
    }

private:
    MyButtonHandler* m_buttonHandler;
};

class MyApp : public wxApp
{
public:
    virtual bool OnInit()
    {
        MyFrame* frame = new MyFrame("wxWidgets Button Example");
        frame->Show(true);
        return true;
    }
};

wxIMPLEMENT_APP(MyApp);
