How to change file info shown in qt examples

[emp1953]

I am using the file finder dialog example at https://doc.qt.io/archives/qt-4.8/qt...s-example.html
In the code they grab and display the size of the file. For me having the date is more helpful than having the size.

Here is the code that does it:

void Window::showFiles(const QStringList &files)
{
    for (int i = 0; i < files.size(); ++i) {
        QFile file(currentDir.absoluteFilePath(files[i]));
        qint64 size = QFileInfo(file).size();
 
        QTableWidgetItem *fileNameItem = new QTableWidgetItem(files[i]);
        fileNameItem->setFlags(fileNameItem->flags() ^ Qt::ItemIsEditable);
        QTableWidgetItem *sizeItem = new QTableWidgetItem(tr("%1 KB")
                                             .arg(int((size + 1023) / 1024)));
        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("%1 file(s) found").arg(files.size()) +
#if defined(Q_OS_SYMBIAN) || defined(Q_WS_MAEMO_5)
                             (" (Select file to open it)"));
#else
                             (" (Double click on a file to open it)"));
#endif
    filesFoundLabel->setWordWrap(true);
}

void Window::showFiles(const QStringList &files)
{
    for (int i = 0; i < files.size(); ++i) {
        QFile file(currentDir.absoluteFilePath(files[i]));
        qint64 size = QFileInfo(file).size();

        QTableWidgetItem *fileNameItem = new QTableWidgetItem(files[i]);
        fileNameItem->setFlags(fileNameItem->flags() ^ Qt::ItemIsEditable);
        QTableWidgetItem *sizeItem = new QTableWidgetItem(tr("%1 KB")
                                             .arg(int((size + 1023) / 1024)));
        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("%1 file(s) found").arg(files.size()) +
#if defined(Q_OS_SYMBIAN) || defined(Q_WS_MAEMO_5)
                             (" (Select file to open it)"));
#else
                             (" (Double click on a file to open it)"));
#endif
    filesFoundLabel->setWordWrap(true);
}

To copy to clipboard, switch view to plain text mode 

I can't find info on what is in the list when the line
filesTable->setItem(row, 1, sizeItem);
is executed.

Thanks for any help

Added after 12 minutes:

I found it in the QFileInfo class the function is .lastModified() It returns a QDateTime.

but now I can't get that time date to print in the file dialog box, first I'd like to format it so its just mm/dd/yyyy, then I want it in the dialog box

I added

QDateTime fdate = (files).lastModified();
qDebug() << fdate.toString();

I changed:
QTableWidgetItem *sizeItem = new QTableWidgetItem(tr("%1 KB")
.arg(int((size + 1023) / 1024)));

to:
QTableWidgetItem *sizeItem = new QTableWidgetItem(tr("")
.arg(QString(files)));

Compiles and prints all the dates & times correctly for all of the files found.

I can't get it to print in the dialog box.

QTableWidgetItem *sizeItem = new QTableWidgetItem(tr("").arg(QString(files)));

Should be:

QTableWidgetItem *sizeItem = new QTableWidgetItem(tr("%1").arg(QString(files)));

QTableWidgetItem *sizeItem = new QTableWidgetItem(tr("%1").arg(QString(files)));

To copy to clipboard, switch view to plain text mode 

The "%1" is required and tells QString to put the value returned by the arg() call in place of the %1. If you wanted to place multiple values in a formatted string, you would write something like:

QTableWidgetItem *sizeItem = new QTableWidgetItem(tr("First item is %1, second item is %2, etc.").arg(QString(files)).arg( QString( "Item 2")) );

QTableWidgetItem *sizeItem = new QTableWidgetItem(tr("First item is %1, second item is %2, etc.").arg(QString(files)).arg( QString( "Item 2")) );

To copy to clipboard, switch view to plain text mode 

And if what you want to put in the second column is the date, you would obviously not want to pass a QStringList (which is what "files" is), but instead a QString formatted to contain the date for files[i]. You have already done this for your QDebug statement.
