Check whether a string is a valid filename with Qt
- by ereOn
Hi,
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.
Examples:
// 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.
Many thanks.
