These are possible because gnuplot graphics_toolkit executed different process
and octave and gnuplot are communicated via pipe.
The fltk and qt are executed in part of process of octave.

The below is my guess
Notepad++ is based on Scintilla[1]. The other Scintilla based editor is SciTE.
In the SciTE execute external console process never represent GUI based 
graphics directory.
(octave+gnuplot is an exception because of reason described the above)

cmd/c is a trick to pass the process to another command window and then 
fltk and qt are executed but this loses the control of octave prompt from 
notepad++.
