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&#40;&#41;&#41;
    cout << iter.filePath().toStdString();
else
    cout << "failed\n";

}

int main()
{
someFunction();

getchar();
return 0;

}
@

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

bq. The QDirIterator constructor takes a QDir or a directory as argument. After construction, the iterator is located before the first directory entry.

Your iterator is placed on an invalid entry. You will have to call QDirIterator::next() at least once to place it on the first valid entry.
@
QDirIterator it("/etc", QDirIterator::Subdirectories);
while (it.hasNext()) {
qDebug() << it.next();

// /etc/.
// /etc/..
// /etc/X11
// /etc/X11/fs
// ...

}
