[Qt-interest] signal emitted eveytime the dialog closes, in QT internally

[Thomas Ganshorn]

You do not have to implement the signal.
Signals are automatically implemented when defined with signals keyword.
(This is done by the moc compiler who reads signals and knows unless defined
otherwise all following functions are to be defined as signals).
 
to call a signal you can just call the functionname (finished() ) or for better
readability write
emit finished()
 
 
in your case you only have to write a slot that gets connected with finished.
in this slot you can then handle whatever you want to do
