I thought it would work like insertFromMimeData [1].
I tested it with QTextEdit widget and works fine!

I need that to execute multi-line command in my shell i.e.:
>>> if True:
. . .    print "Hello"
. . . if False:
. . .    print "Bye Bye"

so the last command line only paste the text doesnt run it!

Also, I implemented dropEvent() and has worked only for drag and drop event
and not to paste :-(

Anyway, thanks a lot!
