Question

现在我在QText浏览器中显示类似/ home / binary /的内容。现在我希望通过单击此文本打开文件夹。怎么做？提前致谢

这是我的示例代码。我显示结果小号

bool MainWindow::displayResult(multimap<string,
的字符串＆GT; ＆amp; resultMap，string＆amp; filePath） { multimap :: iterator iter; bool fileStatus = false; int noOfLocFound = 0，forAppending = 0; QString no;
    noOfLocFound = resultMap.size();

    if ( noOfLocFound != 0 )
        ui->textBrowser->append( "<i>File found at <b>" + no.setNum (
noOfLocFound）+“locations”）;
    for ( forAppending = 0,iter = resultMap.begin(); iter !=
resultMap.end（）; ITER ++， forAppending ++） { string file = iter-＆gt; first; string dir = iter-＆gt; second;
        if ( forAppending == 0)
            filePath.append(dir);
        else
            filePath.append(","+dir);

        QString qdir = QString::fromStdString(dir);

        cout << "Display";

        ui->textBrowser->append( qdir );
        fileStatus = true;

    }

    if ( fileStatus == false )
    {
        ui->textBrowser->append("File not
发现“）; 返回false; }
    return true;
}

通过“打开文件夹”，您的意思是，打开一个文件对话框，供用户选择给定目录中的内容吗？

如果是这样，您可能希望将QTextBrowser的点击信号连接到看起来像这样的插槽：

// connect events, in MyWindow constructor, or whereever...
connect(textbrowser, SIGNAL(mousePressEvent(QMouseEvent*)), this, SLOT(openFileDialog(QMouseEvent*)));

void MyWindow::openFileDialog(QMouseEvent* event) {
    Q_UNUSED(event);

    QStringList files = QFileDialog::getOpenFileNames(this, "Select a file...",
        textbrowser.plainText());

    // do something with the files here...
}
