1 this->setWindowTitle("QDockWidget"); 2 QFont font("ZYsong18030",12); 3 this->setFont(font); 4 /***中央窗体***/ 5 QTextEdit *mainTextEdit=new QTextEdit("Main Window",this); 6 mainTextEdit->setAlignment(Qt::AlignCenter); 7 this->setCentralWidget(mainTextEdit); 8 /***停靠窗口1***/ 9 QDockWidget *dockWidget1=new QDockWidget("DockWidget1",this); 10 /***设置停靠窗口1的特征及活动区域***/ 11 dockWidget1->setFeatures(QDockWidget::DockWidgetMovable); 12 dockWidget1->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea); 13 QTextEdit *textEdit1=new QTextEdit("this dockwidget1 can be moved between docks by the user."); 14 dockWidget1->setWidget(textEdit1); 15 this->addDockWidget(Qt::RightDockWidgetArea,dockWidget1); 16 /***停靠窗口2***/ 17 QDockWidget *dockWidget2=new QDockWidget("DockWidget2",this); 18 dockWidget2->setFeatures(QDockWidget::DockWidgetFloatable | QDockWidget::DockWidgetClosable); 19 dockWidget2->setAllowedAreas(Qt::RightDockWidgetArea); 20 QTextEdit *textEdit2=new QTextEdit("this dockwidget2 can be floated as an independent window,and can be closed."); 21 dockWidget2->setWidget(textEdit2); 22 this->addDockWidget(Qt::RightDockWidgetArea,dockWidget2); 23 /***停靠窗口3***/ 24 QDockWidget *dockWidget3=new QDockWidget("DockWidget3",this); 25 dockWidget3->setFeatures(QDockWidget::AllDockWidgetFeatures); 26 QTextEdit *textEdit3=new QTextEdit("this dockwidget3 can be closed,moved,and floated."); 27 dockWidget3->setWidget(textEdit3); 28 this->addDockWidget(Qt::RightDockWidgetArea,dockWidget3); 29 }
3、堆栈窗口类QStackedWidget类
运行结果：
实现过程：
代码部分1（纯代码）：
1 QDialog *dialog=new QDialog(); 2 this->setCentralWidget(dialog); 3 /***新建一个QListWidget类并加入3个项目***/ 4 QListWidget *list=new QListWidget(); 5 list->insertItem(0,"window1"); 6 list->insertItem(1,"window2"); 7 list->insertItem(2,"window3"); 8 /***新建3个列表项对应的3个切换label***/ 9 QLabel *label1=new QLabel("WindowTest1"); 10 QLabel *label2=new QLabel("WindowTest2"); 11 QLabel *label3=new QLabel("WindowTest3"); 12 /***将label加入堆栈窗口中***/ 13 QStackedWidget *stack=new QStackedWidget(); 14 stack->addWidget(label1); 15 stack->addWidget(label2); 16 stack->addWidget(label3); 17 QHBoxLayout *hLayout=new QHBoxLayout; 18 hLayout->setMargin(5); 19 hLayout->setSpacing(5); 20 hLayout->addWidget(list); 21 hLayout->addWidget(stack,0,Qt::AlignCenter); 22 hLayout->setStretchFactor(list,1); 23 hLayout->setStretchFactor(stack,3); 24 centralWidget()->setLayout(hLayout); 25 connect(list,SIGNAL(currentRowChanged(int)),stack,SLOT(setCurrentIndex(int)));
代码部分2（设计器+代码）：
1 构造函数 2 ui->listWidget->insertItem(0,"window1"); 3 ui->listWidget->insertItem(1,"window2"); 4 ui->listWidget->insertItem(2,"window3"); 5 6 ui->stackedWidget->addWidget(ui->page); 7 ui->stackedWidget->addWidget(ui->page_2); 8 ui->stackedWidget->addWidget(ui->page_3); 9 列表窗口行值改变时的响应函数 10 void Dialog::on_listWidget_currentRowChanged(int currentRow) 11 { 12 ui->stackedWidget->setCurrentIndex(currentRow); 13 }
4、综合实例：修改用户资料
运行结果：
（1）基本信息
（2）联系方式
（3）详细资料
代码部分1（纯代码）：
1 基本信息 2 /**** 左侧 ****/ 3 UserNameLabel =new QLabel(tr("用户名：")); 4 UserNameLineEdit =new QLineEdit; 5 6 NameLabel =new QLabel(tr("姓名：")); 7 NameLineEdit =new QLineEdit; 8 9 SexLabel =new QLabel(tr("性别：")); 10 SexComboBox =new QComboBox; 11 SexComboBox->addItem(tr("女")); 12 SexComboBox->addItem(tr("男")); 13 14 DepartmentLabel =new QLabel(tr("部门：")); 15 DepartmentTextEdit =new QTextEdit; 16 17 AgeLabel =new QLabel(tr("年龄：")); 18 AgeLineEdit =new QLineEdit; 19 20 OtherLabel =new QLabel(tr("备注：")); 21 OtherLabel->setFrameStyle(QFrame::Panel|QFrame::Sunken); 22 23 LeftLayout =new QGridLayout(); 24 LeftLayout->addWidget(UserNameLabel,0,0); 25 LeftLayout->addWidget(UserNameLineEdit,0,1); 26 27 LeftLayout->addWidget(NameLabel,1,0); 28 LeftLayout->addWidget(NameLineEdit,1,1); 29 30 LeftLayout->addWidget(SexLabel,2,0); 31 LeftLayout->addWidget(SexComboBox,2,1); 32 33 LeftLayout->addWidget(DepartmentLabel,3,0); 34 LeftLayout->addWidget(DepartmentTextEdit,3,1); 35 36 LeftLayout->addWidget(AgeLabel,4,0); 37 LeftLayout->addWidget(AgeLineEdit,4,1); 38 39 LeftLayout->addWidget(OtherLabel,5,0,1,2); 40 LeftLayout->setColumnStretch(0,1); 41 LeftLayout->setColumnStretch(1,3); 42 /****右侧****/ 43 HeadLabel =new QLabel(tr("头像： ")); //右上角部分 44 HeadIconLabel =new QLabel; 45 QPixmap icon("312.png"); 46 HeadIconLabel->setPixmap(icon); 47 HeadIconLabel->resize(icon.width(),icon.height()); 48 UpdateHeadBtn =new QPushButton(tr("更新")); 49 50 TopRightLayout =new QHBoxLayout(); 51 TopRightLayout->setSpacing(20); 52 TopRightLayout->addWidget(HeadLabel); 53 TopRightLayout->addWidget(HeadIconLabel); 54 TopRightLayout->addWidget(UpdateHeadBtn); 55 56 IntroductionLabel =new QLabel(tr("个人说明：")); //右下角部分 57 IntroductionTextEdit =new QTextEdit; 58 59 RightLayout =new QVBoxLayout(); 60 RightLayout->setMargin(10); 61 RightLayout->addLayout(TopRightLayout); 62 RightLayout->addWidget(IntroductionLabel); 63 RightLayout->addWidget(IntroductionTextEdit); 64 /*************************************/ 65 QGridLayout *mainLayout =new QGridLayout(this); 66 mainLayout->setMargin(15); 67 mainLayout->setSpacing(10); 68 mainLayout->addLayout(LeftLayout,0,0); 69 mainLayout->addLayout(RightLayout,0,1); 70 mainLayout->setSizeConstraint(QLayout::SetFixedSize);
1 联系方式 2 EmailLabel =new QLabel(tr("电子邮件：")); 3 EmailLineEdit =new QLineEdit; 4 5 AddrLabel =new QLabel(tr("联系地址：")); 6 AddrLineEdit =new QLineEdit; 7 8 CodeLabel =new QLabel(tr("邮政编码：")); 9 CodeLineEdit =new QLineEdit; 10 11 MoviTelLabel =new QLabel(tr("移动电话：")); 12 MoviTelLineEdit =new QLineEdit; 13 MoviTelCheckBook =new QCheckBox(tr("接收留言")); 14 15 ProTelLabel =new QLabel(tr("办公电话：")); 16 ProTelLineEdit =new QLineEdit; 17 18 mainLayout =new QGridLayout(this); 19 mainLayout->setMargin(15); 20 mainLayout->setSpacing(10); 21 mainLayout->addWidget(EmailLabel,0,0); 22 mainLayout->addWidget(EmailLineEdit,0,1); 23 mainLayout->addWidget(AddrLabel,1,0); 24 mainLayout->addWidget(AddrLineEdit,1,1); 25 mainLayout->addWidget(CodeLabel,2,0); 26 mainLayout->addWidget(CodeLineEdit,2,1); 27 mainLayout->addWidget(MoviTelLabel,3,0); 28 mainLayout->addWidget(MoviTelLineEdit,3,1); 29 mainLayout->addWidget(MoviTelCheckBook,3,2); 30 mainLayout->addWidget(ProTelLabel,4,0); 31 mainLayout->addWidget(ProTelLineEdit,4,1); 32 mainLayout->setSizeConstraint(QLayout::SetFixedSize);
1 详细资料 2 NationalLabel =new QLabel(tr("国家/地址：")); 3 NationalComboBox =new QComboBox; 4 NationalComboBox->insertItem(0,tr("中国")); 5 NationalComboBox->insertItem(1,tr("美国")); 6 NationalComboBox->insertItem(2,tr("英国")); 7 8 ProvinceLabel =new QLabel(tr("省份：")); 9 ProvinceComboBox =new QComboBox; 10 ProvinceComboBox->insertItem(0,tr("江苏省")); 11 ProvinceComboBox->insertItem(1,tr("山东省")); 12 ProvinceComboBox->insertItem(2,tr("浙江省")); 13 14 CityLabel =new QLabel(tr("城市：")); 15 CityLineEdit =new QLineEdit; 16 17 IntroductLabel =new QLabel(tr("个人说明：")); 18 IntroductTextEdit =new QTextEdit; 19 20 mainLayout =new QGridLayout(this); 21 mainLayout->setMargin(15); 22 mainLayout->setSpacing(10); 23 mainLayout->addWidget(NationalLabel,0,0); 24 mainLayout->addWidget(NationalComboBox,0,1); 25 mainLayout->addWidget(ProvinceLabel,1,0); 26 mainLayout->addWidget(ProvinceComboBox,1,1); 27 mainLayout->addWidget(CityLabel,2,0); 28 mainLayout->addWidget(CityLineEdit,2,1); 29 mainLayout->addWidget(IntroductLabel,3,0); 30 mainLayout->addWidget(IntroductTextEdit,3,1); 31 修改关闭按钮 32 stack =new QStackedWidget(this); 33 stack->setFrameStyle(QFrame::Panel|QFrame::Raised); 34 baseInfo =new BaseInfo(); 35 contact =new Contact(); 36 detail =new Detail(); 37 stack->addWidget(baseInfo); 38 stack->addWidget(contact); 39 stack->addWidget(detail); 40 41 AmendBtn =new QPushButton(tr("修改")); 42 CloseBtn =new QPushButton(tr("关闭")); 43 QHBoxLayout *BtnLayout =new QHBoxLayout; 44 BtnLayout->addStretch(1); 45 BtnLayout->addWidget(AmendBtn); 46 BtnLayout->addWidget(CloseBtn); 47 48 QVBoxLayout *RightLayout =new QVBoxLayout(this); 49 RightLayout->setMargin(10); 50 RightLayout->setSpacing(6); 51 RightLayout->addWidget(stack); 52 RightLayout->addLayout(BtnLayout);
悄悄咪咪说一句：纯代码是真的很冗余
代码部分2（设计器）：
这就很简单了（代码部分只需要将QListWidget的行索引改变时的信号与QStackedWidget的setCurrentIndex(currentRow)槽连接即可）
1 void UserInfor::on_ListWidget_currentRowChanged(int currentRow) 2 { 3 ui->StackedWidget->setCurrentIndex(currentRow); 4 }
小总结：在这个实例的设计过程中，我发现QLabel有setFrameStyle()函数设置，但QLineEdit类是没有的；
在设计器中可以直接设置frameShape为Panel，frameShadow为Sunken；
QComboBox下拉框中的各项可以直接在设计器中双击添加，QListWidget中的项目可以在设计器中点击直接添加；
QStackedWidget在设计器中添加不同层次的窗口时，不同窗口是显示在不同的page上的，需要在每个page上布好局。
