Example #1

File: mainwindow.cpp Project: Hasimir/PySide

MainWindow::MainWindow()
{
    QMenu *fileMenu = new QMenu(tr("&File"));

    QAction *quitAction = fileMenu->addAction(tr("E&xit"));
    quitAction->setShortcut(tr("Ctrl+Q"));

    menuBar()->addMenu(fileMenu);

//  For convenient quoting:
//! [0]
QListWidget *listWidget = new QListWidget(this);
listWidget->setSelectionMode(QAbstractItemView::SingleSelection);
listWidget->setDragEnabled(true);
listWidget->viewport()->setAcceptDrops(true);
listWidget->setDropIndicatorShown(true);
//! [0] //! [1]
listWidget->setDragDropMode(QAbstractItemView::InternalMove);
//! [1]

    this->listWidget = listWidget;

    connect(quitAction, SIGNAL(triggered()), this, SLOT(close()));
