What is a kioslave you ask yourself?
|
||
|
|
|
||
|
|
A kioslave is a program designed to be intimately familiar with a certian
|
||
|
|
protocol, so that a standardized interface can be used to get at data from
|
||
|
|
any number of places. A few examples are the http and ftp kioslaves,
|
||
|
|
which using nearly identical methods will retrieve data from an http or
|
||
|
|
ftp server respectively.
|
||
|
|
|
||
|
|
Well, that's nice. How do they work?
|
||
|
|
|
||
|
|
To understand it, you'll need two ice cubes, a pair of handcuffs, and a
|
||
|
|
ferret. Some Crisco (or other shortening) is optional. Well, that aside,
|
||
|
|
this document focuses on the business end of the whole kio library. The
|
||
|
|
ioslave. See the documentation of the SlaveBase class for the methods
|
||
|
|
you need to reimplement, and see
|
||
|
|
http://developer.kde.org/documentation/design/kde/ioslaves/ for more docu
|
||
|
|
online.
|
||
|
|
|
||
|
|
That's nice, but how can I use it?
|
||
|
|
|
||
|
|
Any time you'd like to use non blocking IO over a high level protocol
|
||
|
|
(such as HTTP or FTP) a kioslave is for you.
|
||
|
|
|
||
|
|
That's nice, but how do I use it?
|
||
|
|
|
||
|
|
Basically, you create "jobs" by calling a public KIO::blah method
|
||
|
|
(the correct prototypes, etc, are in kio/job.h). Once this is done, you
|
||
|
|
connect to the result() signal, and wait for the result. There are
|
||
|
|
other signals emitted by jobs, see kio/jobclasses.h. Once again,
|
||
|
|
see the online documentation for more.
|
||
|
|
|
||
|
|
|
||
|
|
If you are interested in working on an ioslave,
|
||
|
|
the following slaves are severely lacking in functionality:
|
||
|
|
|
||
|
|
SMTP
|
||
|
|
SMB
