Qt常用工具实现之文件查找器

Qt实现文件查找器，以表格的形式显示文件及其大小，我们还可以添加时间日期，和文件管理器一样的功能
案例代码下载：findfiles.zip:

void Window::showFiles(const QStringList &files)
{
    for (int i = 0; i < files.size(); ++i) {
        const QString &fileName = files.at(i);
        const QString toolTip = QDir::toNativeSeparators(fileName);
        const QString relativePath = QDir::toNativeSeparators(currentDir.relativeFilePath(fileName));
        const qint64 size = QFileInfo(fileName).size();
        QTableWidgetItem *fileNameItem = new QTableWidgetItem(relativePath);
        fileNameItem->setData(absoluteFileNameRole, QVariant(fileName));
        fileNameItem->setToolTip(toolTip);
        fileNameItem->setFlags(fileNameItem->flags() ^ Qt::ItemIsEditable);
        QTableWidgetItem *sizeItem = new QTableWidgetItem(tr("%1 KB")
                                             .arg(int((size + 1023) / 1024)));
        sizeItem->setData(absoluteFileNameRole, QVariant(fileName));
        sizeItem->setToolTip(toolTip);
        sizeItem->setTextAlignment(Qt::AlignRight | Qt::AlignVCenter);
        sizeItem->setFlags(sizeItem->flags() ^ Qt::ItemIsEditable);

        int row = filesTable->rowCount();
        filesTable->insertRow(row);
        filesTable->setItem(row, 0, fileNameItem);
        filesTable->setItem(row, 1, sizeItem);
    }
    filesFoundLabel->setText(tr("%n file(s) found (Double click on a file to open it)", 0, files.size()));
    filesFoundLabel->setWordWrap(true);
}
