Adding QStringList to QListView

[Tomasz]

Hello!

I've listed some directories to QStringList. Now I want to put that list into QListView. How can I do it? My code:

void MainWindow::listMyDirs()
{
    QDir myDir("/home/");
    QStringList list = myDir.entryList (QDir::Dirs|QDir::NoDotAndDotDot, QDir::Name);
 
    // ui->listaCzujnikow->setModel() or smething??
}

void MainWindow::listMyDirs()
{
    QDir myDir("/home/");
    QStringList list = myDir.entryList (QDir::Dirs|QDir::NoDotAndDotDot, QDir::Name);

    // ui->listaCzujnikow->setModel() or smething??
}

To copy to clipboard, switch view to plain text mode 

thanks in advance
best regards
Tomasz

See QStringListModel.

EDIT: Ehm, better use QFileSystemModel direct!

See QStringListModel.

How can I use it here? Some code would be very helpful.

I've tried:

QDir myDir("/home/");
 
    QStringListModel list(myDir.entryList (QDir::Dirs|QDir::NoDotAndDotDot, QDir::Name));
 
    ui->myList->setModel(&list);

QDir myDir("/home/");

    QStringListModel list(myDir.entryList (QDir::Dirs|QDir::NoDotAndDotDot, QDir::Name));

    ui->myList->setModel(&list);

To copy to clipboard, switch view to plain text mode 

but it doesn't work. It's compiling but list is empty...

thanks in advance
best regards

Old same c++ weakness... Create it on the heap.

It works! Thanks! But why it's necessary to create that object on heap to make it work?

thanks in advance

Because otherwise your model gets deleted at the scope's end. So when your view is displayed the model does not exist any more. And without a model, there is nothing to display.
