I wonder if it's possible to develop extensions (aka Add-Ons) for
Firefox (or in my case Thunderbird). I'm totaly unfamiliar to the
stuff right now. But the advantage I could think of is 1) I don't know
C++ and 2) it is easy to cross compile code for different platforms.
Writing extensions without javascript needs XPCOM bindings. I saw that
there're some for using the gecko rendering engine in Firefox. Is
there a more general thing to access XPCOM? Anybody has experience
with this? I'm a total C++ noob.
Try looking at the gecko integration package. It is meant to do the opposite
(integrating gecko in your app) but it also uses
xpcom, and you should get ideas from that.
Thanks Michael, I already found that. You may find there the
relationship between XPCOM C++ bindings for Gecko and how to use them
in fpc app. In my case i'm interested to access the adressbook in
Thunderbird. Even if I would get along to find the right functions I
have no idea how to process returned data. I guess you have to be a
very good C++ developer for that as well. But that's ways over my
skills, I think.
I don't think so: everything is done using interfaces, and as soon as
you have the definition of an interface, the rest should not be a problem.
The main problem is to get the interface definitions.
I think they provide an IDL file, and you'd have to produce a pascal file
from it. As I remember, there should be an idl-pascal on the net somewhere.
Michael.
