C2061 - Syntax error

[MichelleK]

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.

[MichelleK]

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

[sierdzio]

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 So, are you saying that QListViewItem is no longer valid in this version?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?

[SGaist]

QListViewItem was already no longer valid in Qt 4.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
