System info dialog source?

Question

I'd like to know where I could find (in launchpad preferably) the source code of this dialog.

Answer 1

Here: https://launchpad.net/unity-control-center

I leave you with a meaningless sentence to meet the answer length limit.

Answer 2

Expanding on a recent answer that gets the PID of a clicked window, you could run this, click the window and it should (some thing don't work well) give you the package.

dpkg -S $(sed 's/\x0.*//' /proc/$(xprop _NET_WM_PID | awk '{print $NF}')/cmdline)

Once you have the package, it's fairly simple to find on Launchpad or through packages.ubuntu.com.
