Qt学习——聊天的QQ列表QToolBox类

QToolBox展示出来的抽屉效果可以设计联系人列表

下面展示类似聊天软件QQ的主界面

头文件主要就是定义这些联系人QToolButton：

#include <QToolBox>
#include <QToolButton>
class Drawer : public QToolBox
{
    Q_OBJECT
public:
    Drawer(QWidget *parent=0,Qt::WindowFlags f=0);
private:
    QToolButton *toolBtn1_1;
    QToolButton *toolBtn1_2;
    QToolButton *toolBtn1_3;
    QToolButton *toolBtn1_4;
    QToolButton *toolBtn1_5;
    QToolButton *toolBtn2_1;
    QToolButton *toolBtn2_2;
    QToolButton *toolBtn3_1;
    QToolButton *toolBtn3_2;
};

源文件将联系人加入到三个QToolBox中

#include "drawer.h"
#include <QGroupBox>
#include <QVBoxLayout>
Drawer::Drawer(QWidget *parent,Qt::WindowFlags f)
    :QToolBox(parent,0)
{
    setWindowTitle(tr("My QQ"));
//***************初始化我的好友*****************
    toolBtn1_1=new QToolButton;
    toolBtn1_1->setText(tr("张三"));
    toolBtn1_1->setIcon(QPixmap("res/11.bmp"));
    toolBtn1_1->setIconSize(QPixmap("res/11.bmp").size());
    toolBtn1_1->setAutoRaise(TRUE);
    toolBtn1_1->setToolButtonStyle(Qt::ToolButtonTextBesideIcon);
