How to exclude a specific file extension from QDir::entryList

Hi community,
I know how to specify the file extensions that I would like to be considered when I call the QDir::entryList method:

Code:

---

QDir dir(path);
QStringList files = dir.entryList(QStringList() << "*.ext1" << "*.ext2", QDir::Files | QDir::NoDot | QDir::NoDotAndDotDot);

---

In this case the files having extensions ext1 and ext2 only are considered. But how to exclude a specific extension?
For example I would like to considere ALL the extensions except a specific one ( in my case *.conf )

Thx

Hi, I'm not sure if entryList() can do that. But you can simply get all files, then iterate over the stringlist and remove the matching files afterwards.

Something like this:

Code:

---

// Note that since QFileInfo::suffix() returns the extension -without- a leading ".", the code allows the
// excluded extensions list to contain either "ext" or ".ext" and will check for both.
//
// This will also include files with no extensions, so if that is not desired, check the suffix for isEmpty()
// and discard them too.
//
// Usage:
//
// QStringList noBinaryList = excludedEntryList( path, QStringList() << ".exe" << "dll", QDir::Files | QDir::NoDot | QDir::NoDotAndDotDot );
 
// Untested code! Might contain bugs
 
QStringList excludedEntryList( const QString & path, const QStringList & excludedExts, QDir::Filters filters )
{
    QStringList filteredEntries;
    QDir dir( path );
    QFileInfoList unfilteredInfos = dir.entryInfoList( filters );
    for ( QFileInfo info : unfilteredInfos )
    {
        QString  ext = info.suffix();
        if ( !excludedExts.contains( ext ) && !excludedExts.contains( "." + ext ) )
            filteredEntries.push_back( info.fullPath() );
    }
    return filteredEntries;
}
