telnet wxwidgets 完整代码

Telnet是一种通过网络连接远程计算机的协议，而wxWidgets是一个跨平台GUI工具包。如果您想使用wxWidgets编写一个telnet客户端，可以参考以下代码：

#include <wx/wx.h>
#include <wx/socket.h>

class MyFrame : public wxFrame
{
public:
    MyFrame(wxWindow* parent, const wxString& title)
        : wxFrame(parent, wxID_ANY, title)
    {
        m_textCtrl = new wxTextCtrl(this, wxID_ANY, wxEmptyString,
            wxDefaultPosition, wxDefaultSize, wxTE_MULTILINE);

        m_button = new wxButton(this, wxID_ANY, "Connect");
        m_button->Bind(wxEVT_BUTTON, &MyFrame::OnButtonConnect, this);

        wxBoxSizer* sizer = new wxBoxSizer(wxVERTICAL);
        sizer->Add(m_textCtrl, 1, wxEXPAND | wxALL, 10);
        sizer->Add(m_button, 0, wxALIGN_RIGHT | wxALL, 10);
        SetSizerAndFit(sizer);
    }

private:
    void OnButtonConnect(wxCommandEvent& event)
    {
        // Create a TCP socket
        wxSocketClient* socket = new wxSocketClient(wxSOCKET_WAITALL);

        // Bind the socket events
        socket->Bind(wxEVT_SOCKET, &MyFrame::OnSocketEvent, this);

        // Connect to the telnet server
        socket->Connect("localhost", 23);

        m_textCtrl->AppendText("Connecting to localhost:23...\n");
    }

    void OnSocketEvent(wxSocketEvent& event)
    {
        wxSocketBase* socket = event.GetSocket();
        switch (event.GetSocketEvent())
        {
            case wxSOCKET_CONNECTION:
                m_textCtrl->AppendText("Connected!\n");
                break;

            case wxSOCKET_INPUT:
            {
                char buffer[1024];
                int size = socket->Read(buffer, sizeof(buffer)).LastCount();
                buffer[size] = '\0';
                m_textCtrl->AppendText(wxString::FromUTF8(buffer));
                break;
            }

            case wxSOCKET_LOST:
                m_textCtrl->AppendText("Disconnected!\n");
                socket->Destroy();
                break;
        }
    }

    wxTextCtrl* m_textCtrl;
    wxButton* m_button;
};

class MyApp : public wxApp
{
public:
    virtual bool OnInit()
    {
        MyFrame* frame = new MyFrame(nullptr, "Telnet Client");
        frame->Show();
        return true;
    }
};

wxIMPLEMENT_APP(MyApp);

以上代码使用了wxSocketClient类来创建TCP套接字，并通过绑定事件来处理连接、接收数据和断开连接等操作。在点击“Connect”按钮时，它将连接到本地主机的23号端口（即telnet服务）。请注意，该代码仅提供了一个基本的框架，您可能需要根据实际情况进行修改和完善。
