how to make a folder non writable

GrahamL

Hi
I have a need to make a folder non writable
I have made a QFile object and set the permissions to 0 but I am still able to perform a mkpath operation

		QFile file(dir.path());
		QString s = file.fileName();
		QFile::Permissions permissions = file.permissions();
		QFile::Permissions oldPermissions = permissions;
		permissions &= QFile::ExeGroup;
		permissions &= QFile::ReadOwner;
		permissions &= QFile::WriteOwner;
		permissions &= QFile::ReadUser;
		permissions &= QFile::WriteUser;
		permissions &= QFile::ExeUser;
		permissions &= QFile::ReadGroup;
		permissions &= QFile::WriteGroup;
		permissions &= QFile::ReadOther;
		permissions &= QFile::WriteOther;
		permissions &= QFile::ExeOther;
		file.setPermissions(permissions);

What is the correct way of doing this

Thanks

HI
Are you sure QFile will do it with a folder ?
Maybe try
QFile::Permissions perm = QFileInfo( "c:/ACCESS_DENIED/" ).permissions();
Since it mention folder also.
Never tried it! so just suggestion.

Hi
Thanks for your reply
I dont think this will allow me to set the permissions on the folder though

Hi
Yeah, after I posted ,
I realized that QFileInfo seems to have no setPermissions so
its back to QFile again. sorry.

Its under linux I assume ?

So the user the program runs under/as do have the permission to set permissions ?

Actually this is running under Windows
Dont think I can do it using Qt tho

@GrahamL
oh
and you did notice
extern Q_CORE_EXPORT int qt_ntfs_permission_lookup;

Well, if you trying to set the Read Only flag for the folder,
i think you are right that it wont work with Qt and you would have to resort to
SetFileAttributes

If that is the effect you want to get.

OK
Thanks for your help
