With recent versions of SIP, you can do:
import sip
sip.delete(widget.layout())
=================
Otherwise, if you're bound to an older version, a less clear but effective way
is to force SIP to transfer ownership of the object back to Python. By doing
so, you tie the lifetime of the C++ object to the lifetime of the Python object:
import sip
L = widget.layout()
sip.transferback(L)
del L # drop last Python reference -> destroy C++ object
Or, a more compact but equivalent form:
import sip
sip.transferback(widget.layout())
Of course, for this to work, you need to make sure you don't have *any* other
Python reference to that layout.
=================
A third solution involves the fact that QLayout is a QObject, so you can use
its deleteLater() method:
L = widget.layout()
L.deleteLater()
QCoreApplication.sendPostedEvents(L, QEvent.DeferredDelete)
