Hey, I'm interested in working on ktorrent, but I'm not sure what I need to know to do that. I've loaded the project in KDevelop and looked around, but it's quite a bit to take in. Any specific suggestions on what to learn to make sense of the source?

There isn't really a document which describes the architecture of KTorrent. I think your best option is probably to just ask what you want to know.

Well not a document, but like, where I should begin from. Let me be more specific: what part of the code to start reading from?

Try generating doxygen documentation and take a look at the libktorrent/interfaces for start.

First off, thanks for the reply. I built the doxygen docs in kdevelop and have started snooping around and found bt::TorrentControl which seems to be the heart of the system. I'm not sure which interfaces belong to libktorrent and which not, doxygen just gives me namespaces like bt, kt. Any specific interfaces I can look for?

#2: How do I build KTorrent in KDevelop? It complains of no Makefile or autogen.sh present.

Interfaces are in libktorrent/interfaces directory like I mentioned and interface for bt::TorrentControl is kt::TorrentInterface.

#2
Where did you get the sources from?

Ah ok, I'll look at that interface first then.

I downloaded the sources from ktorrent.org.

Download the sources from SVN trunk (see FAQ) and you'll have a project ready to be used with KDevelop.

Alright, will download from SVN later. I'm still somewhat new to Qt, and I'm used to having a main widget in main.cpp before the QApplication (or KApplication in this case) going into its execution loop. What is the main widget here? If it's too hard to answer, I was hoping you could direct me to some documentation about how that works.

apps/main.cpp

I lied, sorry

apps/ktorrent/main.cpp is the correct path

Yes, that's the main.cpp that I referred to in my last question. I'm not asking its path, I'm asking about the lack of a main widget inside the main function of that file.

The actual main widget is created in KTorrentApp::newInstance

OK, So I checked in the newInstance function inherited from KUniqueApplication http://developer.kde.org/documentation/library/3.5-api/kdelibs-apidocs/kdecore/html/kuniqueapplication_8cpp-source.html#l00466

It seems to depend on there being a main widget defined somewhere, but in KTorrent's main.cpp I couldn't find one.

Also:

I downloaded the SVN from 4/28 but it's not compiling in KDevelop either, complains about no active targets.

The main widget is created in KTorrentApp::newInstance, we override the one defined in KUniqueApplication

Try it from the commandline then.
