KArchiveFile
Represents a file entry in a KArchive.
Definition: karchive.h:491
KArchive
KArchive is a base class for reading and writing archives.
Definition: karchive.h:43
KArchive::writeDir
virtual bool writeDir(const TQString &name, const TQString &user, const TQString &group)=0
If an archive is opened for writing then you can add new directories using this function.
KArchive::closeArchive
virtual bool closeArchive()=0
Closes the archive.
KArchive::device
TQIODevice * device() const
The underlying device.
Definition: karchive.h:96
KArchive::doneWriting
virtual bool doneWriting(uint size)=0
Call doneWriting after writing the data.
KArchive::openArchive
virtual bool openArchive(int mode)=0
Opens an archive for reading or writing.
KArchive::writeData
bool writeData(const char *data, uint size)
Write data into the current file - to be called after calling prepareWriting.
Definition: karchive.cpp:353
KArchive::writeSymLink
bool writeSymLink(const TQString &name, const TQString &target, const TQString &user, const TQString &group, mode_t perm, time_t atime, time_t mtime, time_t ctime)
Writes a symbolic link to the archive if the archive must be opened for writing.
Definition: karchive.cpp:327
KArchive::prepareWriting
virtual bool prepareWriting(const TQString &name, const TQString &user, const TQString &group, uint size)=0
Here's another way of writing a file into an archive: Call prepareWriting, then call writeData() as m...
KArchive::writeFile
virtual bool writeFile(const TQString &name, const TQString &user, const TQString &group, uint size, const char *data)
If an archive is opened for writing then you can add a new file using this function.
Definition: karchive.cpp:228
KZip
This class implements a tdeioslave to access zip files from KDE.
Definition: kzip.h:54
KZip::fileName
TQString fileName()
The name of the zip file, as passed to the constructor.
Definition: kzip.h:84
KZip::ExtraField
ExtraField
Describes the contents of the "extra field" for a given file in the Zip archive.
Definition: kzip.h:89
KZip::Compression
Compression
Describes the compression type for a given file in the Zip archive.
Definition: kzip.h:112
TDEIO::symlink
TDEIO_EXPORT SimpleJob * symlink(const TQString &target, const KURL &dest, bool overwrite, bool showProgressInfo=true)
Create or move a symlink.
Definition: job.cpp:808
