Customised file manager

Nemooo

Hello!
I am new in Qt. Everything begun when I tried to add additional columns in QFileSystemModel. I didn't find the solution. By I got some hints that it is possible to create my own model using QStandardItemModel. I have found something like this:

const QIcon fileIcon = qApp->style()->standardPixmap(QStyle::SP_FileIcon);
const QIcon dirIcon = qApp->style()->standardPixmap(QStyle::SP_DirIcon);

QStandardItemModel model(0, 2);
QFileInfoList files = QDir("/Users").entryInfoList();
foreach(const QFileInfo &fi, files) {
    QStandardItem *item = new QStandardItem(QString("%0").arg(fi.fileName()));
    item->setFlags(Qt::ItemIsEnabled | Qt::ItemIsSelectable);
    if (fi.isDir())
        item->setData(dirIcon, Qt::DecorationRole);
    else
        item->setData(fileIcon, Qt::DecorationRole);
    model.appendRow(item);
}

QTreeView view;
view.setModel(&model);
view.show();

Of course it is far from real QFileSystemModel. At least I don't know how to create QObject::connect to open folders when you click so it reminds to real file manager where I could have more than 5 columns (for example for media info).
Can anybody give me some hints please.

Thank you.

Hi and welcome to devnet,

What do you want to show in that additional column ?

Hi. I want to write a program that calculates selected audio files duration. I need a column that shows audio files durations (min, sec) and when I select some of them somewhere I create QLabel which shows resulted durations sum. The column with audio durations is just for convenience.

The solution is KExtraColumnsProxyModel. The author is the maintainer of anything relating to models in Qt.

If you use MSVC2017 compiler you can find a pre-compiled version of the library containing that class here: 32 bit/64 bit

Thank you very much, but I don't know how to use and attach it. Moreover I would like to use standard Qt library for training

I don't know how to use and attach it

for training

Being able to use 3rd party libraries is a must-have for a programmer. Way more important (I can't stress this enough) than knowing how to implement a custom proxy model.

Thank you very much. I will try to attach this library
