QFileDialog实现同时选择文件和文件夹，确认取消按钮英文问题解决方法

如下图所示，需求是同时能够选择文件或者文件夹，但是QFileDialog文件窗口类要么只能选文件，要么只能选文件夹，无法同时去选择文件和文件夹；

要实现这样的需求，封装了一个类，实现同时选择文件和文件夹；

头文件

#ifndef MULTIFILEDIRDIALOG_H

#define MULTIFILEDIRDIALOG_H

#include <QObject>

#include <QFileDialog>

class MultiFileDirDialog : public QFileDialog

{

    Q_OBJECT

public:

    MultiFileDirDialog(QWidget *parent);

    ~MultiFileDirDialog();

    QStringList m_listSelect;

signals:

    public slots :

        void go();

private:

};

#endif // MULTIFILEDIRDIALOG_H

源文件

#include "MultiFileDirDialog.h"

#include<QListView>

#include <QTreeView>

#include <QDialogButtonBox>

#include <QTranslator>

#include <QPushButton>

#include <QDialogButtonBox>

#pragma execution_character_set("utf-8")

MultiFileDirDialog::MultiFileDirDialog(QWidget *parent)

    : QFileDialog(parent)

{

    setOption(QFileDialog::DontUseNativeDialog, true);

    //支持多选

    QListView *listView = findChild<QListView*>("listView");

    if (listView)

        listView->setSelectionMode(QAbstractItemView::ExtendedSelection);

    QTreeView *treeView = findChild<QTreeView*>();

    if (treeView)

        treeView->setSelectionMode(QAbstractItemView::ExtendedSelection);

    QDialogButtonBox *button = findChild<QDialogButtonBox *>("buttonBox");

    if (button)

    {

        /*QPushButton* selectbutton = button->button(QDialogButtonBox::Open);

        if (selectbutton)

        {

            button->removeButton(selectbutton);

            const QString strselect = "选择";

            selectbutton = button->addButton(QDialogButtonBox::Ok);

            selectbutton->setText("选择");

        }

        QPushButton* canclebutton = button->button(QDialogButtonBox::Cancel);

        if (canclebutton)

        {

            button->removeButton(canclebutton);

            const QString strcalcel = "取消";

            canclebutton=button->addButton(strcalcel, QDialogButtonBox::RejectRole);

            canclebutton->setText("取消");

        }*/

        button->clear();

        QPushButton* accpetbutton = new QPushButton(button);

        accpetbutton->setText("确定");

        button->addButton((QAbstractButton*)accpetbutton, QDialogButtonBox::AcceptRole);

        QPushButton* cancel = new QPushButton(button);

        cancel->setText("取消");

        button->addButton((QAbstractButton*)cancel, QDialogButtonBox::RejectRole);

        /*button->button(QDialogButtonBox::Ok)->setText(tr("确定"));

        button->button(QDialogButtonBox::Cancel)->setText(tr("取消"));*/

        disconnect(button, SIGNAL(accepted()), this, SLOT(accept()));//使链接失效

        connect(button, SIGNAL(accepted()), this, SLOT(go()));//改成自己的槽

    }

    //无效

    //setLabelText(QFileDialog::FileName, "选择文件:");//英文化文件名称

    //setLabelText(QFileDialog::Reject, "取消");//英文化取消按钮

    //setLabelText(QFileDialog::Accept, "选择");//英文化打开按钮

}

MultiFileDirDialog::~MultiFileDirDialog()

{

}

void  MultiFileDirDialog::go()

{

    m_listSelect = selectedFiles();

    QDialog::accept();

}

其中默认的取消确认按钮始终无法显示中文，所以直接将默认的按钮清除掉，再自己添加两个按钮上去，建立信号槽连接就可以了；

再需求导入选择文件的地方调用创建对象调用；

void AddVedioAnaTask::OnBtnSelectClicked()

{

    //ps/ts/hik/mp4/asf/avi/dahv/flv

    if (m_addType==0)//导入案件

    {

        m_pMultiFileDialog->setOption(QFileDialog::ShowDirsOnly, true);

        //m_pMultiFileDialog->setFileMode(QFileDialog::Directory);

    }

    else//导入子文件

    {

        //m_pMultiFileDialog->setFileMode(QFileDialog::AnyFile);

        m_pMultiFileDialog->setOption(QFileDialog::ShowDirsOnly, false);

        m_pMultiFileDialog->setNameFilter("vedio(*.mp4 *.avi *.dav *.asf *.wmv *.mpg *.ts *.3g2 *.swf *.flv *.m2ts *.mkv *.3gp *.vob *.rmvb *.mov *.webm *.rm *.mts *.mpeg *.264 *.692 *.800 *.801 *.av *.avx *.djl *.dvr *.g64 *.h3crd *.h64 *.h264 *.ifv *.jmv *.kyd *.lvf *.mpk *.nsf *.nv4 *.ps *.rec *.sdv *.sv5 *.swf *.tm4 *.tp *.bhd *.dat *.h265 *.he4 *.m4c *.pep *.smf *.sv4 *.vdg *.601 *.452094848)");

    }

    if (m_pMultiFileDialog->exec() == QDialog::Accepted)

    {

        QStringList selectFiles = m_pMultiFileDialog->selectedFiles();

        if (selectFiles.size() > 0)

        {

            QString strItem = "";

            for (int i = 0; i < selectFiles.size(); i++)

            {

                strItem = selectFiles[i];

                if (!strItem.isEmpty())

                {

                    if (m_TaskFileMap.find(strItem) == m_TaskFileMap.end())

                    {

                        addFileToTable(strItem);

                    }

                }

            }

        }

    }

}

}
