Cross-platform way of constructing an FS path with Qt [duplicate]

Answer 1

From Qt 4.6 QDir documentation,

Qt uses "/" as a universal directory separator in the same way that "/" is used as a path separator in URLs. If you always use "/" as a directory separator, Qt will translate your paths to conform to the underlying operating system.

So, I guess QDir will be helpful for you.

Answer 2

You can either use "/" directly or use QDir::separator(). But in general use a QDir for this (which translates "/" to the platform specific path separator for you).

Answer 3

Just use "/" when staying in the Qt world. To convert the path for non-Qt classes and functions etc., use QDir::toNativeSeparators( path ).
