Re: How nautilus places item on desktop window?

Hi Leena,

as a general advice, you should look at sources from git master [1] to
make sure you get the latest code, as things might have changed in the
meanwhile (and they actually changed quite a lot from 2.30).

You should be able to debug with printf() from nautilus-icon-container.c
just fine; maybe you just put them in an uncommon code path that was not
executed? libnautilus-private is just an internal library that includes
more low-level objects, which are usually instantiated from the other
classes in src/

I fail to parse your second question, but generally the best answer I
can give you to these very specific questions (such as 1 and 3) is "you
have to dig in the code to find it out" :) Code for icon container's
keynav starts around here [2].

NautilusIconContainer's icon layouting code is old, quite complex and
might have its bugs for sure; I don't think you can find anybody here on
the list who can answer these questions off-hand, without looking at the
code, so if you have a specific bug in mind, feel free to mention it
here or open a bug report at the GNOME bugzilla.
