# KFilterBase Class Reference

`from PyKDE4.kdecore import *`

## Detailed Description

This is the base class for compression filters such as gzip and bzip2. It's pretty much internal. Don't use directly, use KFilterDev instead.

Internal:

## Static Method Documentation

KFilterBase findFilterByFileName | ( | QString | fileName
| ) |  |  |

Call this to create the appropriate filter for the file named fileName.

Parameters:

  | fileName | the name of the file to filter

Returns:
  the filter for the fileName, or 0 if not found

KFilterBase findFilterByMimeType | ( | QString | mimeType
| ) |  |  |

Call this to create the appropriate filter for the mimetype mimeType. For instance application/x-gzip.

Parameters:

  | mimeType | the mime type of the file to filter

Returns:
  the filter for the mimeType, or 0 if not found
