Detailed Description

A class for reading and writing compressed data onto a device (e.g. file, but other usages are possible, like a buffer or a socket)

 KFilterDev ( KFilterBase * filter )

Create a KFilterDev for a given filter (e.g. gzip, bzip2 etc.)

[static]

Call this to create the appropriate filter device for base working on file . The returned QIODevice has to be deleted after using.
