【Qt】QDockWidget

一个简单的停靠窗口类：

设置三种停靠窗口：（1）可浮动；（2）可移动、可关闭；（3）具备以上所有特性

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

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
{
    setWindowTitle(tr("DockWindows"));//设置主窗口标题栏文字
    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);  //将此编辑框设置为主窗口的中央窗口

    //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 *te1 = new QTextEdit();
    te1->setText(tr("Window1,The dock widget can be moved between docks and users"""));
    dock->setWidget(te1);
    addDockWidget(Qt::RightDockWidgetArea,dock);

    //停靠窗口2
    dock=new QDockWidget(tr("DockWindow2"),this);
    dock->setFeatures(QDockWidget::DockWidgetClosable|QDockWidget::DockWidgetFloatable);//可关闭可浮动
    QTextEdit *te2 = new QTextEdit();
    te1->setText(tr("Window2,The dock widget can be detac from the main window,""and float as an independent window,and can be closed"));
    dock->setWidget(te2);
    addDockWidget(Qt::RightDockWidgetArea,dock);

    //停靠窗口3
    dock=new QDockWidget(tr("DockWindow3"),this);
    dock->setFeatures(QDockWidget::AllDockWidgetFeatures);//所有特性
    QTextEdit *te3 = new QTextEdit();
    te1->setText(tr("Window3,The dock widget can be closed,moved,and float"));
    dock->setWidget(te3);
    addDockWidget(Qt::RightDockWidgetArea,dock);



}

MainWindow::~MainWindow()
{

}

如果有部分函数看不懂，建议先理解前面零星的小控件的设置。
