C2061 - Syntax error



  • I am new at QT, so I apologize if this is an easy question, but I have typed in an example that I found that uses QListViewItem and for some reason it can not find it, even though I am including qlistview.h. Here is the header where I am getting the error:

    @
    #include <QMainWindow>
    #include <qlistview.h>
    #include <QtXml\QDomDocument>

    class OutlineTree : public QListView
    {
    Q_OBJECT
    public:
    OutlineTree( const QString filename, QWidget *parent = 0, const char *name = 0);
    ~OutlineTree();

    private:
    QDomDocument domTree;
    void getHeaderInformation(const QDomElement &header);
    void buildTree(QListViewItem * parentItem, const QDomElement &parentElement);
    };
    @

    And here is the .pro file, in case you find it useful:

    @
    QT += core gui

    greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

    TARGET = DomTreeWithPart
    TEMPLATE = app

    SOURCES += main.cpp
    mainwindow.cpp
    OutlineTree.cpp

    HEADERS += mainwindow.h

    FORMS += mainwindow.ui
    @

    Any thoughts or suggestions would be greatly appreciated.

    You need to include QListViewItem, too.



  • I did try that. It said there was no such file.


  • Moderators

    Oh sorry, I've mistaken that with QListWidgetItem, which does exist. Your example code might be wrong, then.

    Hi,

    QListViewItem is from Qt 3, you should either update your code to use the Qt 4/5 classes or use Qt3Support but it's not a good idea since you seem to learn Qt.

    As a side note it's Qt, QT stands for Apple's QuickTime :)

    Hope it helps



  • I am using Qt 5.0.2. So, are you saying that QListViewItem is no longer valid in this version? If so, what would I use instead?


  • Lifetime Qt Champion

    QListViewItem was already no longer valid in Qt 4.

    Could you explain what you want to achieve so I can better help you ?



  • I was trying to read in an XML file using DOM and create a tree. I found an example online (evidently an old one) and tried to implement it for my file. The code in the class that is supposed to do everything looks like this:

    @
    OutlineTree::OutlineTree( const QString fileName, QWidget *parent, const char *name)
    :QListView( parent, name)
    {
    QFile partFile("c:/qt experiments/database/parts/theFile.xml");
    if (!partFile.open(QIODevice::ReadOnly)) {
    QMessageBox::critical(0, tr("Critical Error"), tr("Parsing error for file"));
    partFile.close();
    return;
    }
    partFile.close();

    //Get the header information from the DOM
    QDomElement root = domTree.documentElement();
    QDomNode node;
    node = root.firstChild();
    while ( !node.isNull()) {
        if (node.isElement() && node.nodeName() == "PART") {
            QDomElement part = node.toElement();
            getHeaderInformation(part);
            break;
        }
        node = node.nextSibling();
    }
    
    //Create the tree view out of the DOM
    node = root.firstChild();
    while (!node.isNull()) {
        if (node.isElement() && node.nodeName() == "PLY") {
            QDomElement plys = node.toElement();
            buildTree(0, plys);
            break;
        }
        node = node.nextSibling();
    }
    

    }

    OutlineTree::~OutlineTree()
    {

    }

    void OutlineTree::getHeaderInformation(const QDomElement &header)
    {
    //no children only attributes
    }

    void OutlineTree::buildTree(QListViewItem * parentItem, const QDomElement &parentElement)
    {
    QListViewItem * thisItem = 0;
    QDomNode node = parentElement.firstChild();
    while (!node.isNull()) {
    //add a new list view item for the outline
    if (parentItem == 0) {
    if (node.isElement() && node,nodeName() == "PLY") {
    thisItem = new QListViewItem(this, thisItem);
    } else {
    thisItem = new QListViewItem(parentItem, thisItem);
    }
    thisItem->setText(0, node.toElement().attribute("NAME"));
    //recursive build of the tree
    buildTree(thisItem, node.toElement());
    }
    node = node.nextSibling();
    }
    }
    @

    Maybe I should just find a more up-to-date example.

    Then I would recommend the reading of Qt 5 doc's about QDomDocument and have look at the DOM Bookmark example. It covers exactly what you want
