I had the assumption that:

Qt Code:
  1. QtCore.QSignalBlocker(mywidget.setValue(somevalue))
To copy to clipboard, switch view to plain text mode 

Would be somewhat equivalent to:

Qt Code:
  1. mywidget.blockSignals(True)
  2. mywidget.setValue(somevalue)
  3. mywidget.blockSignals(False)
To copy to clipboard, switch view to plain text mode 

But, I've found that the latter actually does block the signals while the former appears to do "nothing".

I must be missing something. Anyone have some insight?
