Why i can't select different items in QTreeView



  • I can select only one item , i can't select my two rows for example:
    alt text

    I want to select my two rows in my treeview.
    Code mainwindow.cpp:

    //! [Quoting ModelView Tutorial]
    // modelview.cpp
    #include <QTreeView>
    #include <QStandardItemModel>
    #include <QStandardItem>
    #include "mainwindow.h"
    
    
    const int ROWS = 2;
    const int COLUMNS = 3;
    
    MainWindow::MainWindow(QWidget *parent)
        : QMainWindow(parent)
    {
        treeView = new QTreeView(this);
        setCentralWidget(treeView);
        standardModel = new QStandardItemModel ;
    
        QList<QStandardItem *> preparedRow =prepareRow("first", "second", "third");
        QStandardItem *item = standardModel->invisibleRootItem();
        // adding a row to the invisible root item produces a root element
        item->appendRow(preparedRow);
    
        QList<QStandardItem *> secondRow =prepareRow("111", "222", "333");
        // adding a row to an item starts a subtree
        preparedRow.first()->appendRow(secondRow);
    
        QList<QStandardItem *> thirdRow =prepareRow("111", "222", "333");
        // adding a row to an item starts a subtree
        preparedRow.first()->appendRow(thirdRow);
    
        treeView->setModel(standardModel);
        treeView->expandAll();
    }
    
    QList<QStandardItem *> MainWindow::prepareRow(const QString &first,
                                                    const QString &second,
                                                    const QString &third)
    {
        QList<QStandardItem *> rowItems;
        rowItems << new QStandardItem(first);
        rowItems << new QStandardItem(second);
        rowItems << new QStandardItem(third);
        return rowItems;
    }
    //! [Quoting ModelView Tutorial]
    

    Thanks in advance!





  • @Ratzz Thanks i solved using:

    treeView->setSelectionMode(QAbstractItemView::MultiSelection);
        treeView->setSelectionBehavior(QAbstractItemView::SelectRows);
    

    i will check too:
    http://doc.qt.io/qt-4.8/qabstractitemview.html#selectionMode-prop



  • @Ratzz for qtreewidget the example will be the same? because i'm using both and maybe will be the same thing?



  • @RIVOPICO said in Why i can't select different items in QTreeView:
