GUI command profiling

Hello,
How to know what commands run as a result of the gui-user interaction?
Like, when i select a drive from my main menu, what commands get executed to ask my password & then mount & open it in nautilus? And what gets executed when i copy-paste.
I noticed the time taken by copy-paste is less, than executing cp or rsync in terminal.
PS:oops, i hit save instead of preview. i dont have edit permissions yet. So, wrote 2nd. Moderator, please dont think i am double posting.
Thanks.

It's likely that most GUI program do the system calls themselves rather than calling the shell.
If you need to know how to perform a specific task you'll need to make a specific search for it.
So, whatever system calls the desktop environment is making, do they get logged in some file? Or, is their any book that tells what calls/cmds are executed behind the UI.
I am curious to know what calls/cmd the DE uses to do a task.
did no one so far thought to know what goes on behind the clicks? Looking into sources is a straight forward approach, but highly inefficient for an individual, considering the amount of code a DE has.
Is there no book about this?

i might have miss understood your question, so bear with me.
i am thinking that it would be dependant of the language the program is written in and the style o the programer. Some programs have a well documented wiki with the source code or you could look for the command line instrucion within the source code with a ctrl+f in gedit. If you can't find it then they probably used some other means. For example c might have a way to do the same thing and python another. But that should be found in the documentation help for each language.

To get a list of the low-level system API read http://linux.die.net/man/2/syscalls (or man syscalls)
Most programs would use wrapper libraries to these functions which are usually quite cumbersome to use.
