停靠窗口QDockWidget类的使用

一、dockwindows.cpp中的代码段

#include "mainwindow.h"
#include<QTextEdit>
#include<QDockWidget>

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
{
    
    
    setWindowTitle(tr("DockWindows")); // 设置主窗口的标题栏文字
    QTextEdit *te = new QTextEdit(this); // 定义一个QTextEdit对象作为主窗口
    te->setText(tr("Main Window"));
    te->setAlignment(Qt::AlignCenter);
    setCentralWidget(te); // 将此编辑框设为主窗口的中央窗体

    // 停靠窗口1
    QDockWidget *dock = new QDockWidget(tr("DockWindow1"),this);
    dock->setFeatures(QDockWidget::DockWidgetMovable); // 可移动
    dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);
    QTextEdit *tel = new QTextEdit();
    tel->setText(tr("Window1,The dock widget can be moved between docks by the user"
                     " "));
    dock->setWidget(tel);
    addDockWidget(Qt::RightDockWidgetArea,dock);

    // 停靠窗口2
    dock = new QDockWidget(tr("DockWindow2"),this);
    dock->setFeatures(QDockWidget::DockWidgetClosable | QDockWidget::
                      DockWidgetFloatable); // 可关闭、可移动
    dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);
    QTextEdit *tel2 = new QTextEdit();
    tel2->setText(tr("Window2,The dock widget can be , "" and, and "));
    dock->setWidget(tel2);
    addDockWidget(Qt::RightDockWidgetArea,dock);

    // 停靠窗口3
    dock = new QDockWidget(tr("DockWindow3"),this);
    dock->setFeatures(QDockWidget::AllDockWidgetFeatures); // 全部特性
    dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);
    QTextEdit *tel3 = new QTextEdit();
    tel3->setText(tr("Window3,The dock widget can be , and, and "));
    dock->setWidget(tel3);
    addDockWidget(Qt::RightDockWidgetArea,dock);



}

MainWindow::~MainWindow()
{
    
    
}
