1、创建一个基于QWidget的应用，基类选择QWidget，类名Mindows

给combox添加可编辑属性

实现选择目录功能：

window.h中：

#ifndef WINDOW_H
    #define WINDOW_H
    
    #include <QWidget>
    
    QT_BEGIN_NAMESPACE
    class QComboBox;
    QT_END_NAMESPACE
    
    class Window : public QWidget
    {
        Q_OBJECT
    
    public:
        Window(QWidget *parent = 0);
        ~Window();
    
    private slots:
        void browse();
    
    private:
        QComboBox *createComboBox(const QString &text = QString());
        QComboBox *directoryComboBox;
    };
    
    #endif // WINDOW_H

main.cpp中

#include "window.h"
    #include <QtWidgets>
    
    void Window::browse()
    {
        QString directory =
                QDir::toNativeSeparators(QFileDialog::getExistingDirectory(
                                             this,
                                             tr("find files"),
                                             QDir::currentPath()));
        if (!directory.isEmpty()) {
            if (directoryComboBox->findText(directory) == -1)
                directoryComboBox->addItem(directory);
            directoryComboBox->setCurrentIndex(directoryComboBox->findText(directory));
        }
    }
    
    QComboBox *Window::createComboBox(const QString &text)
    {
        QComboBox *comboBox = new QComboBox;
        comboBox->addItem(text);
        comboBox->setEditable(true);
        comboBox->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Preferred);
        return comboBox;
    }
    
    Window::Window(QWidget *parent)
        : QWidget(parent)
    {
       QPushButton *browseButton = new QPushButton(tr("&Browse..."), this);
       connect(browseButton, &QAbstractButton::clicked, this, &Window::browse);
    
       directoryComboBox = createComboBox(QDir::toNativeSeparators(QDir::currentPath()));
    
       QGridLayout *mainLayout = new QGridLayout(this);
       mainLayout->addWidget(new QLabel(tr("In directory:")), 2, 0);
       mainLayout->addWidget(directoryComboBox, 2, 1);
       mainLayout->addWidget(browseButton, 2, 2);
    
       setWindowTitle(tr("Find Files"));
       const QRect screenGeometry = QApplication::desktop()->screenGeometry(this);
       resize(screenGeometry.width() / 4, screenGeometry.height() / 6);
    }
    
    Window::~Window()
    {
    
    }
