1. QSplitter 分割窗口
代码：
QSplitter *splitterMain=new QSplitter(Qt::Horizontal,0); QTextEdit *textLeft=new QTextEdit(QObject::tr("Left Widget"),splitterMain); textLeft->setAlignment(Qt::AlignCenter);//文字对齐方式 QSplitter *splitterRight=new QSplitter(Qt::Vertical,splitterMain); splitterRight->setOpaqueResize(false);//分隔条在拖拽时是否实时更新显示 QTextEdit *textUp=new QTextEdit(QObject::tr("Top Widget"),splitterRight); textUp->setAlignment(Qt::AlignCenter); QTextEdit *textBottom=new QTextEdit(QObject::tr("Bottom Widget"),splitterRight); textBottom->setAlignment(Qt::AlignCenter); //设定可伸缩空间，第1个参数用于指定设置的控件序号，从0开始编号 //第2个参数为大于0的值，表示此控件为可伸缩控件 splitterMain->setStretchFactor(1,1); splitterMain->setWindowTitle(QObject::tr("Splitter")); splitterMain->show();
2. 停靠窗口QDockWidget类
代码：
setWindowTitle("DockWindows"); QTextEdit *te=new QTextEdit(this); te->setText("Main Windows"); te->setAlignment(Qt::AlignCenter);//居中 setCentralWidget(te);//将此编辑框设为主窗口的中央窗体 QDockWidget *dock=new QDockWidget("DockWindow1",this); dock->setFeatures(QDockWidget::DockWidgetMovable);//可移动 dock->setAllowedAreas(Qt::LeftDockWidgetArea|Qt::RightDockWidgetArea);//窗体可停靠区域的位置 QTextEdit *te1=new QTextEdit(); te1->setText("Window1,The dock widget can be moved between docks by the user"); dock->setWidget(te1); addDockWidget(Qt::RightDockWidgetArea,dock); dock=new QDockWidget("DockWindow2",this); dock->setFeatures(QDockWidget::DockWidgetClosable|QDockWidget::DockWidgetFloatable);//可关闭，可浮动 QTextEdit *te2=new QTextEdit(); te2->setText(tr("Window2, The dock can be detached from the mainwindow,""and floated as an independent window, and can be closed")); dock->setWidget(te2); addDockWidget(Qt::RightDockWidgetArea,dock); dock=new QDockWidget("DockWindow3",this); dock->setFeatures(QDockWidget::AllDockWidgetFeatures);//全部特性 QTextEdit *te3=new QTextEdit(); te3->setText(tr("Window3, The dock can be closed, moved, and floated")); dock->setWidget(te3); addDockWidget(Qt::RightDockWidgetArea,dock);
3. 堆栈窗体QStackedWidget
代码：
setWindowTitle("StackedWidget"); list=new QListWidget(this); list->insertItem(0,"Window1"); list->insertItem(1,"Window2"); list->insertItem(2,"Window3"); label1=new QLabel("WindowTest1"); label2=new QLabel("WindowTest2"); label3=new QLabel("WindowTest3"); stack=new QStackedWidget(this); stack->addWidget(label1); stack->addWidget(label2); stack->addWidget(label3); QHBoxLayout *mainLayout=new QHBoxLayout(this); mainLayout->setMargin(5); mainLayout->setSpacing(5); mainLayout->addWidget(list); mainLayout->addWidget(stack,0,Qt::AlignCenter); mainLayout->setStretchFactor(list,1); mainLayout->setStretchFactor(stack,3); connect(list,SIGNAL(currentRowChanged(int)),stack,SLOT(setCurrentIndex(int)));
4.基本布局（QLayout）
代码：
dialog.h
#ifndef DIALOG_H #define DIALOG_H #include <QDialog> #include <QLabel> #include <QSplitter> #include <QLineEdit> #include <QComboBox> #include <QTextEdit> #include <QGridLayout> #include <QVBoxLayout> #include <QHBoxLayout> #include <QPushButton> #include <QPixmap> class Dialog : public QDialog { Q_OBJECT public: Dialog(QWidget *parent = 0); ~Dialog(); void setDialog(); private: //左侧 QLabel *userNameLabel; QLabel *nameLabel; QLabel *sexLabel; QLabel *departmentLabel; QLabel *ageLable; QLabel *otherLabel; QLineEdit *usernameLineEdit; QLineEdit *nameLineEdit; QComboBox *sexCombox; QTextEdit *departmentTextEdit; QLineEdit *ageLineEdit; QGridLayout *leftLayout; //右侧 QLabel *headLabel; QLabel *headIconLabel; QPushButton *updateHeadBtn; QHBoxLayout *topRightLayout; QLabel *introductionLabel; QTextEdit *introductionLineEdit; QVBoxLayout *rightLayout; //底部 QPushButton *okBtn; QPushButton *cancelBtn; QHBoxLayout *buttomLayout; }; #endif // DIALOG_H
dialog.cpp
#include "dialog.h" Dialog::Dialog(QWidget *parent) : QDialog(parent) { setDialog(); } Dialog::~Dialog() { } void Dialog::setDialog(){ userNameLabel=new QLabel("用户名："); usernameLineEdit=new QLineEdit; nameLabel=new QLabel("姓名："); nameLineEdit=new QLineEdit; sexLabel=new QLabel("性别："); sexCombox=new QComboBox; sexCombox->addItem("女"); sexCombox->addItem("男"); departmentLabel=new QLabel("部门："); departmentTextEdit=new QTextEdit; ageLable=new QLabel("年龄："); ageLineEdit=new QLineEdit; otherLabel=new QLabel("备注："); otherLabel->setFrameStyle(QFrame::Panel|QFrame::Sunken);//控件风格 leftLayout=new QGridLayout(); leftLayout->addWidget(userNameLabel,0,0); leftLayout->addWidget(usernameLineEdit,0,1); leftLayout->addWidget(nameLabel,1,0); leftLayout->addWidget(nameLineEdit,1,1); leftLayout->addWidget(sexLabel,2,0); leftLayout->addWidget(sexCombox,2,1); leftLayout->addWidget(departmentLabel,3,0); leftLayout->addWidget(departmentTextEdit,3,1); leftLayout->addWidget(ageLable,4,0); leftLayout->addWidget(ageLineEdit,4,1); leftLayout->addWidget(otherLabel,5,0,1,2); //设定两列分别占用的空间比例 leftLayout->setColumnStretch(0,1); leftLayout->setColumnStretch(1,3); //右侧 headLabel=new QLabel("头像："); headIconLabel=new QLabel; QPixmap icon(":/image/123.jpg"); headIconLabel->setPixmap(icon); headIconLabel->resize(icon.width(),icon.height()); updateHeadBtn=new QPushButton("更新"); topRightLayout=new QHBoxLayout(); topRightLayout->setSpacing(20); topRightLayout->addWidget(headLabel); topRightLayout->addWidget(headIconLabel); topRightLayout->addWidget(updateHeadBtn); introductionLabel=new QLabel("个人说明"); introductionLineEdit=new QTextEdit; rightLayout=new QVBoxLayout(); rightLayout->setMargin(10); rightLayout->addLayout(topRightLayout); rightLayout->addWidget(introductionLabel); rightLayout->addWidget(introductionLineEdit); okBtn=new QPushButton("确定"); cancelBtn=new QPushButton("取消"); buttomLayout=new QHBoxLayout(); buttomLayout->addStretch();//在按钮之前插入一个占位符，使两个按钮能够靠右对齐 buttomLayout->addWidget(okBtn); buttomLayout->addWidget(cancelBtn); QGridLayout *mainLayout=new QGridLayout(this); mainLayout->setMargin(15); mainLayout->setSpacing(10); mainLayout->addLayout(leftLayout,0,0); mainLayout->addLayout(rightLayout,0,1); mainLayout->addLayout(buttomLayout,1,0,1,2); mainLayout->setSizeConstraint(QLayout::SetFixedSize);//设定最优化显示，并且使用户无法改变对话框大小 }
