Qt equivalent of PathAppend?
Short story: does Qt 4 have an analog of Python's os.path.join?
Long story: I need to add a relative path to the application directory, QCoreApplication::applicationDirPath() in the Right Way (TM), so that the code doesn't depend on the file system directory separator character.
Is merely joining QStrings and using "/" as the separator a good solution?
回答1:
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).
回答2:
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.
回答3:
Just use "/" when staying in the Qt world. To convert the path for non-Qt classes and functions etc., use QDir::toNativeSeparators( path ).
