想简化代码，但是不会用容器。
ChatInterface.h:

C/C++ code

#ifndef CHATINTERFACE_H#define CHATINTERFACE_H#include <QtGui>class ChatInterface:public QToolBox{    Q_OBJECTpublic:    ChatInterface(QWidget *parent = 0,Qt::WindowFlags f = 0);    QToolButton *toolButton1_1;    QToolButton *toolButton1_2;    QToolButton *toolButton1_3;    QToolButton *toolButton1_4;    QToolButton *toolButton2_1;    QToolButton *toolButton2_2;    QToolButton *toolButton2_3;    QToolButton *toolButton3_1;    QToolButton *toolButton3_2;public:    void SetLayout();    void Communicate();public slots:    void test();};#endif // CHATINTERFACE_H

main.cpp

C/C++ code

#include "ChatInterface.h"#include <QApplication>int main(int argc,char **argv){    QApplication app(argc,argv);    ChatInterface *chatInterface = new ChatInterface();    chatInterface->show();        return app.exec();}

每一个按钮我都要触发事件，而事件触发的事情差不多的都是一样，我想用像数组一样，一个for循环，把它们一个一个地连接信号。。。
查了很多的资料，好像要用到什么容器什么的。。。
但是自己又不会用。。。
求各位过路人指点，或者点代码给我研究下，谢谢~~~谢谢~~~谢谢~~~谢谢~~~谢谢~~~谢谢~~~
谢谢~~~谢谢~~~谢谢~~~谢谢~~~谢谢~~~谢谢~~~
弄了一个晚上了。。。
恳请各位帮帮我。。。

[解决办法]

探讨

引用:

你代码里new了3个QGroupBox，把对应的toolbutton加进去，connect时候连QGroupBox，在对应的slot里面根据id判断是哪个按钮再具体处理

是喔，好主意。。。
但是该怎么判断ID？？
connect(myFriends,SIGNAL(clicked()),SLOT(??));
……

[解决办法]
用容器的话，大概是这样的：
声明：
#include<vector>
// 因为不需要自己释放，简单实用指针即可，否则要使用 shared_ptr或者 QSharedPointer
std::vector<QToolButton *> m_buttons;

初始化：
for(int i = 0; i < 8; ++i)
{
QToolButton * btn = new QToolButton();
btn->setIcon(QPixmap(QString("c:/%1.ico").arg(i)));
m_buttons.push_back(btn);
}

事件连接：
connect(m_buttons[1], SIGNAL(clicked()), SLOT(OnButton1());
connect(m_buttons[1], SIGNAL(clicked()), SLOT(OnButton2());
