1、新建QtGUI应用，基类选择QWidget，取消创建界面

2、widget.cpp

#include "widget.h"
    #include <QToolBar>
    #include <QAction>
    
    Widget::Widget(QWidget *parent)
        : QWidget(parent)
    {
        QToolBar *toolbar = new QToolBar(this);
    
        QAction *act[5];
    
        act[0] = new QAction(QIcon(":resources/browser.png"), "Browser", this);
        act[1] = new QAction(QIcon(":resources/calendar.png"), "calendar", this);
        act[2] = new QAction(QIcon(":resources/chat.png"), "chat", this);
        act[3] = new QAction(QIcon(":resources/editor.png"), "editor", this);
        act[4] = new QAction(QIcon(":resources/mail.png"), "mail", this);
    
        act[0]->setShortcut(Qt::Key_Control | Qt::Key_E);
        act[0]->setToolTip("This is a ToolTip");
    
        toolbar->setToolButtonStyle(Qt::ToolButtonTextBesideIcon);
    
        for(int i = 0 ; i < 5 ; i++)
        {
            toolbar->addAction(act[i]);
        }
    
        connect(act[0], SIGNAL(triggered()), this, SLOT(trigger1()));
        connect(act[1], SIGNAL(triggered()), this, SLOT(trigger2()));
        connect(act[2], SIGNAL(triggered()), this, SLOT(trigger3()));
        connect(act[3], SIGNAL(triggered()), this, SLOT(trigger4()));
        connect(act[4], SIGNAL(triggered()), this, SLOT(trigger5()));
    }
    
    void Widget::trigger1()
    {
        qDebug("Tool Button 1 click.");
    }
    
    void Widget::trigger2()
    {
        qDebug("Tool Button 2 click.");
    }
    
    void Widget::trigger3()
    {
        qDebug("Tool Button 3 click.");
    }
    
    void Widget::trigger4()
    {
        qDebug("Tool Button 4 click.");
    }
    
    void Widget::trigger5()
    {
        qDebug("Tool Button 5 click.");
    }
    
    
    Widget::~Widget()
    {
    
    }
