[SOLVED] QDir::exists(const QString & name) and dirs

[tucnak]

Dirs. Is this function will work with them or only with files. If no, how can I review exists of dir.

If you want to know if a file exists use,

@
#include <QFile>

bool return;

QFile filename("location/of/file");
return = filename.exists();
if(return == true){
// success
}
else{
// failed
}
@

I would assume QDir would be the same way...aka replace QFile with QDir.

Instead of asking and waiting for someone to answer, you could just try it yourself. Should be manageable to create this code independently:

@
qDebug() << "existing dir: " << QDir("/path/to/existing/dir-or-file").exists();
qDebug() << "missing dir: " << QDir("/path/to/non-existing/dir-or-file").exists();
@

For further research: QFileInfo, including exists(), isDir(), isFile().

You could have stumbled over this class by reading [[Doc:QDir]] API docs. It's mentioned in the "See also" section and even at the description of QDir::exists(). Is it really that hard to click on the link?

Thanks, Volker. It was informative.
