Detailed Description

This class provides the functionality to download and upload "new stuff".

Applications have to subclass KNewStuff, implement the pure virtual functions and link to against libknewstuff.

By calling download() the download process is started which means that a list of "providers" is fetched from a "master server", information about new stuff is collected from the providers and presented to the user. Selected entries get downloaded and installed to the application. The required functions to install new stuff are provided by implementing install(). The location where the downloaded files are stored can be customized by reimplementing downloadDestination().

By calling upload() the upload process is started which means the user has to select a provider from the list fetched from the master server and to put in information about the entry to be uploaded. Then the file to be uploaded is fetched from the application by calling createUploadFile() and transfered to the upload destination specified in the provider list.

Member Function Documentation

virtual bool KNewStuff::createUploadFile

(

const QString &

fileName

)

[pure virtual]

Create a file to be uploaded to a "new stuff provider" and return the filename.

The format of the file is application specific. The only constraint is that the corresponding install() implementation is able to use the file.

Parameters:

fileName

name of the file to be written

Returns:

true on success, false on error.

Implemented in KNewStuffGeneric, KNewStuffSecure, and TestNewStuff.

void KNewStuff::download

(

)

Start download process.

Definition at line 67 of file knewstuff.cpp.

QString KNewStuff::downloadDestination

(

KNS::Entry *

entry

)

[virtual]

Return a filename which should be used as destination for downloading the specified new stuff entry.

Reimplement this function, if you don't want the new stuff to be downloaded to a temporary file.

Reimplemented in KNewStuffGeneric.

Definition at line 72 of file knewstuff.cpp.

KNS::Engine* KNewStuff::engine

(

)

[inline, protected]

Get the pointer to the engine.

Needed by subclasses to access the KNS::Engine object.

Definition at line 154 of file knewstuff.h.

virtual bool KNewStuff::install

(

const QString &

fileName

)

[pure virtual]

Install file to application.

The given fileName points to the file downloaded by the KNewStuff engine. This is a temporary file by default. The application can do whatever is needed to handle the information contained in the file.

The function returns true, when the installation was successful and false if were errors.

Parameters:

fileName

name of downloaded file

Implemented in KNewStuffGeneric, KNewStuffSecure, and TestNewStuff.

QWidget * KNewStuff::parentWidget

(

)

const

Return parent widget.

Definition at line 57 of file knewstuff.cpp.

QString KNewStuff::type

(

)

const

Return type of data.

Definition at line 52 of file knewstuff.cpp.

void KNewStuff::upload	(	const QString &	fileName,
		const QString	previewName
	)

Upload with pre-defined files.

Definition at line 83 of file knewstuff.cpp.

void KNewStuff::upload

(

)

Start upload process.

Definition at line 78 of file knewstuff.cpp.
