Issue using QDir/QDirIterator

[prophetjohn]

Can someone tell me what is wrong with this code? It compiles fine, but I can’t seem to figure out how to set a directory.

#include <QtCore/QDir>
#include <QtCore/QDirIterator>
#include <iostream>
 
using namespace std;
 
void someFunction()
{
    QString path = "C:/Users/";
    QDirIterator iter(path);
 
    if(iter.fileInfo().exists() || iter.fileInfo().isDir() || iter.fileInfo().isFile())
        cout << iter.filePath().toStdString();
    else
        cout << "failed\n";
}
 
int main()
{
    someFunction();
 
    getchar();
    return 0;
}

#include <QtCore/QDir>
#include <QtCore/QDirIterator>
#include <iostream>
 
using namespace std;
 
void someFunction()
{
    QString path = "C:/Users/";
    QDirIterator iter(path);
 
    if(iter.fileInfo().exists() || iter.fileInfo().isDir() || iter.fileInfo().isFile())
        cout << iter.filePath().toStdString();
    else
        cout << "failed\n";
}
 
int main()
{
    someFunction();
     
    getchar();
    return 0;
}

To copy to clipboard, switch view to plain text mode 

It prints “failed” every time. What am I doing wrong?

From the QDirIterator docs:

After construction, the iterator is located before the first directory entry.

Thanks. While testing I found that iter.hasNext() evaluated to true, so i tried iter.next() before the if/else block and it still prints "failed". Any ideas?

Works fine here:

QString path = "/var/spool/";
QDirIterator iter(path);
iter.next();
if(iter.fileInfo().exists() || iter.fileInfo().isDir() || iter.fileInfo().isFile())
    qDebug() << iter.filePath();
else
    qDebug() << "failed\n";

QString path = "/var/spool/";
QDirIterator iter(path);
iter.next();
if(iter.fileInfo().exists() || iter.fileInfo().isDir() || iter.fileInfo().isFile())
    qDebug() << iter.filePath();
else
    qDebug() << "failed\n";

Outputs: "/var/spool/cron"

Ah, I found my problem. Thanks!
