Detailed Description
KFileMetaInfo provides metadata extracted from a file or other resource.
When instantiating an instance of this class, the metadata related to it will be retrieved and stored in the instance. The data can be inspected through KFileMetaInfoItem objects.

| __init__ | ( | self, | ||
| QString | path, | |||
| QString | mimetype=QString(), | |||
| KFileMetaInfo.WhatFlags | w=KFileMetaInfo.Everything | |||
| ) |
Construct a KFileMetaInfo that contains metainformation about the resource pointed to by path.
When w is not Everything, a limit of 64kbytes is imposed on the file size.

- that c'tor is not thread-safe
| __init__ | ( | self ) |
Construct a KFileMetaInfo instance from another one.
| __init__ | ( | self, | ||
| KFileMetaInfo | a0 | |||
| ) |

Enumeration Documentation
| What |
This is used to specify what a KFileMetaInfo object should read, so you can specify if you want to read "expensive" items or not. This is like a preset which can be customized by passing additional parameters to constructors.
