Expand description

A key in the “thumbnail” namespace for checking whether the normal thumbnail is outdated.

This attribute is true if the normal thumbnail is up-to-date with the file it represents, and false if the file has been modified since the thumbnail was generated.

If FILE_ATTRIBUTE_THUMBNAILING_FAILED_NORMAL is true and this attribute is false, it indicates that thumbnailing may be attempted again and may succeed.

Corresponding #GFileAttributeType is FileAttributeType::Boolean.
