Qt实现QQ界面

1.Qt实现QQ界面是通过QToolBox类来实现的，基本结构是：QToolBox里面装QGroupBox，然后QGroupBox里面装QToolButton，设置好相关属性即可

2.定义类继承QToolBox

class Drawer : public QToolBox

3.在构造函数中完成布局，头文件代码展示，为了避免代码重复定义初始化函数

initToolButton

#ifndef DRAWER_H
#define DRAWER_H

#include <QWidget>
#include <QToolBox>//工具盒类，层叠窗口，抽屉效果实现
#include <QToolButton>

class Drawer : public QToolBox
{
    Q_OBJECT

public:
    Drawer(QWidget *parent=0,Qt::WindowFlags f = 0);
    ~Drawer();
    void initToolButton(QToolButton  **tb,QString name,QString pathpic);


private :
    QToolButton *toolbtn1;
    QToolButton *toolbtn2;
    QToolButton *toolbtn3;
    QToolButton *toolbtn4;
    QToolButton *toolbtn5;
    QToolButton *toolbtn11;
    QToolButton *toolbtn12;
    QToolButton *toolbtn21;
    QToolButton *toolbtn22;

};

#endif // DRAWER_H

4.主要代码为.cpp文件

#include "drawer.h"
#include<QGroupBox>
#include <QVBoxLayout>
#include <QDebug>


Drawer::Drawer(QWidget *parent, Qt::WindowFlags f):QToolBox(parent,f)
{
    setWindowTitle("QQ");
    initToolButton(&toolbtn1,"张远山","1.png");
    qDebug()<<"ok";
    initToolButton(&toolbtn2,"东奥","2.png");
    qDebug()<<"ok";
    initToolButton(&toolbtn3,"孙选成","3.png");
    qDebug()<<"ok";
    initToolButton(&toolbtn4,"司宽","4.png");
    qDebug()<<"ok";
    initToolButton(&toolbtn5,"张宇","5.png");
    qDebug()<<"ok";
    QGroupBox *gb1 = new QGroupBox;
    QVBoxLayout *lay1 = new QVBoxLayout(gb1);

    lay1->setMargin(10);
    lay1->setAlignment(Qt::AlignHCenter);

    lay1->addWidget(toolbtn1);
    lay1->addWidget(toolbtn2);
    lay1->addWidget(toolbtn3);
    lay1->addWidget(toolbtn4);
    lay1->addWidget(toolbtn5);
   // lay1->addStretch();

    initToolButton(&toolbtn11,"刘翔","11.png");
    initToolButton(&toolbtn12,"詹姆斯","12.png");
    QGroupBox *gb2 = new QGroupBox;
    QVBoxLayout *lay2 = new QVBoxLayout(gb2);
    lay2->addWidget(toolbtn11);
    lay2->addWidget(toolbtn12);
    lay2->setMargin(10);
    lay2->setAlignment(Qt::AlignHCenter);

    initToolButton(&toolbtn21,"惠子","21.png");
    initToolButton(&toolbtn22,"名人","22.png");
    QGroupBox *gb3 = new QGroupBox;
    QVBoxLayout *lay3 = new QVBoxLayout(gb3);
    lay3->addWidget(toolbtn21);
    lay3->addWidget(toolbtn22);
    lay3->setMargin(10);
    lay3->setAlignment(Qt::AlignHCenter);

    //准备好的抽屉插入TOOlBox中
    this->addItem(gb1,"我的好友");
    this->addItem(gb2,"陌生人");
    this->addItem(gb3,"黑名单");





}

Drawer::~Drawer()
{

}

void Drawer::initToolButton(QToolButton **tb, QString name, QString pathpic)
{

    (*tb) = new QToolButton;
    (*tb)->setText(name);
    (*tb)->setIcon(QPixmap(pathpic));
    (*tb)->setIconSize(QSize(20,20));
    (*tb)->setAutoRaise(true);
    (*tb)->setToolButtonStyle(Qt::ToolButtonTextBesideIcon);


}

5.

(*tb)->setIcon(QPixmap(pathpic));表示设置按钮图标

6.

(*tb)->setAutoRaise(true);表示鼠标离开时按钮自动恢复为弹起状态

7.

(*tb)->setToolButtonStyle(Qt::ToolButtonTextBesideIcon);表示设置按钮文字标签在图标旁边

8.查看运行效果图
