Questions tagged [qdir]

A QDir is a class from the Qt toolkit which provides access to directory structures and their contents.

A QDir is used to manipulate path names, access information regarding paths and files, and manipulate the underlying file system. It can also be used to access Qt's resource system.

The official documentation can be found here for Qt 4.8 and here for Qt 5.
