Qt中的TeamSpeak SDK

Question

我试图在Qt中的个人项目中使用TeamSpeak SDK，当我主要使用这段代码时，它工作得很好

它没有问题地编译。问题是当我在Qt主窗口中使用它时：

Mainwindow.h

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <teamspeak/public_definitions.h>
#include <teamspeak/public_errors.h>
#include <teamspeak/serverlib_publicdefinitions.h>
#include <teamspeak/serverlib.h>

namespace Ui {
   class MainWindow;
}

 class MainWindow : public QMainWindow
 {
      Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();

private:
    Ui::MainWindow *ui;
       void onClientConnected(uint64 serverID, anyID clientID, uint64    channelID, unsigned int* removeClientError);
ServerLibFunctions funcs; // it's a struct that have pointer fucntions
  };

  #endif // MAINWINDOW_H

Mainwindow.cpp

#include "mainwindow.h"
#include "ui_mainwindow.h"

  MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
   ui(new Ui::MainWindow)
 {
   ui->setupUi(this);
   funcs.onClientConnected = onClientConnected; // error here 
 }

 MainWindow::~MainWindow()
 {
   delete ui;
 }

 void MainWindow::onClientConnected(uint64 serverID, anyID clientID,    uint64 channelID, unsigned int* removeClientError) {
char* clientName;
   unsigned int error;

/* Query client nickname */
  if ((error = ts3server_getClientVariableAsString(serverID, clientID,    CLIENT_NICKNAME, &clientName)) != ERROR_ok) {
    char* errormsg;
    if (ts3server_getGlobalErrorMessage(error, &errormsg) == ERROR_ok) {
        printf("Error querying client nickname: %s\n", errormsg);
        ts3server_freeMemory(errormsg);
    }
    return;
}

printf("Client '%s' joined channel %llu on virtual server %llu\n", clientName, (unsigned long long) channelID, (unsigned long long)serverID);

/* Example: Kick clients with nickname "BlockMe from server */
if (!strcmp(clientName, "BlockMe")) {
    printf("Blocking bad client!\n");
    *removeClientError = ERROR_client_not_logged_in;  /* Give a reason */
}
}

我对Mainwindow.cpp中的错误和错误进行了注释：

无法将'MainWindow::onClientConnected‘从类型'void“(MainWindow::)(uint64，anyID，uint64，无符号int*) {aka (MainWindow：)(长无符号int，短无符号int，长无符号int，无符号int*)}”转换为'void ()(uint64，anyID，uint64，unsigned int) {又名void ()(long unsigned int，short unsigned int，long long unsigned int，long long unsigned int，long long unsigned int，unsigned )}’=；^

我使用的是Windows 10 Mingw编译器QT5.6.1

如何在oop c++中使用此回调函数？

我解决了在Qt中使用TeamSpeak的问题，我在main.cpp中初始化了服务器，并在结构中分配了所有的回调函数，现在我可以在主窗口中使用服务器的任何函数，例如，如果我想在文本编辑中显示通道，我可以在任何c++类或Qt对话框中使用它的函数，并且可以在没有问题的情况下调用main.cpp代码。

 // put the fucntion of the call back here
int main(int argc, char *argv[])
{
  QApplication a(argc, argv);

char *version;
short abort = 0;
uint64 serverID;
unsigned int error;
int unknownInput = 0;
uint64* ids;
int i;

struct ServerLibFunctions funcs;

/* Initialize all callbacks with NULL */
memset(&funcs, 0, sizeof(struct ServerLibFunctions));
funcs.onClientConnected          = onClientConnected;
funcs.onClientDisconnected       = onClientDisconnected;
funcs.onClientMoved              = onClientMoved;
funcs.onChannelCreated           = onChannelCreated;
funcs.onChannelEdited            = onChannelEdited;
funcs.onChannelDeleted           = onChannelDeleted;
funcs.onServerTextMessageEvent   = onServerTextMessageEvent;
funcs.onChannelTextMessageEvent  = onChannelTextMessageEvent;
funcs.onUserLoggingMessageEvent  = onUserLoggingMessageEvent;
funcs.onClientStartTalkingEvent  = onClientStartTalkingEvent;
funcs.onClientStopTalkingEvent   = onClientStopTalkingEvent;
funcs.onAccountingErrorEvent     = onAccountingErrorEvent;
funcs.onCustomPacketEncryptEvent = nullptr;
funcs.onCustomPacketDecryptEvent = nullptr;

if((error = ts3server_initServerLib(&funcs, LogType_FILE | LogType_CONSOLE | LogType_USERLOGGING, NULL)) != ERROR_ok) {
    char* errormsg;
    if(ts3server_getGlobalErrorMessage(error, &errormsg) == ERROR_ok) {
        printf("Error initialzing serverlib: %s\n", errormsg);
        ts3server_freeMemory(errormsg);
    }
    return 1;
}

MainWindow w;
w.show();

return a.exec();
 // use any function to edit server in any c++ class as show chan   add chancel and so on
}

使用所有函数来编辑任何c++类中的服务器，它可以工作，我认为我们不需要在main中多次初始化服务器，也不需要在类中初始化它，如果我想使用Qt生成一个VoIP，我们只需要服务器编辑功能，如果有更好的答案，请张贴感谢编辑。

另一种解决方案是使用main中的回调函数初始化结构，并在主窗口或构造函数中的任何c++类中传递它，并使用它初始化TeamSpeak的服务器库。

您的问题可以用下面的简单代码来模拟。根据我的理解，您要分配的函数是一个特定于类的成员。因此，当您试图分配时，编译器将其视为签名不匹配。您可能需要在非类成员中编写所需的功能，然后进行分配。(除非有办法允许这种分配)。

将函数输入的结构作为函数类的朋友，如下所示。

 #include <iostream>

// common namespace
using namespace std;


//Structure with function pointers.
struct funcPtrStruct
{
    public:
    void (*func)(int a, float b);
};


//The non member function that address your functionality
void testFuncOne(int a ,float b)
{
    //Do something
}


//Class implementation
class Test
{

public:
    Test()
    {
        funcPtrStruct funPtrSt;
        //func = &testFunc; //Here the error is shown " a value of type .....can not convert......"
        funPtrSt.func = &testFuncOne; //This is working but it is not a class memeber.
    }
private:

     friend struct funcPtrStruct; //Make the structure of function pointers as your friend.
};


int main() {
    return 0;
}
