It's quite simple, IMHO (at least as you don't need overloaded
class myWidget( QWidget ):
databaseChanged = pyqtSignal(str)
# self.react_to_db is a callable taking one argument.
self.databaseChanged.connect( self.react_to_db )
if database_has_changed :
# database_name has to be a string
(also, note that it's pyqtSignal, not pyQtSignal)
