Is there a way with
Qt 4.6 to check if a given
QString is a valid filename (or directory name) on the current operating system ? I want to check for the name to be valid, not for the file to exist.
// Some valid names test under_score .dotted-name // Some specific names colon:name // valid under UNIX OSes, but not on Windows what? // valid under UNIX OSes, but still not on Windows
How would I achieve this ? Is there some
Qt built-in function ?
I’d like to avoid creating an empty file, but if there is no other reliable way, I would still like to see how to do it in a “clean” way.
I don’t think that Qt has a built-in function, but if Boost is an option, you can use Boost.Filesystem’s name_check functions.
If Boost isn’t an option, its page on name_check functions is still a good overview of what to check for on various platforms.
