Hi,
I've a class that inherits from the 'set' built-in class :
def class Toto( Tutu, set ):
def __init__(self):
set.__init__(self)
When I select the class name 'Toto' in eclipse and I choose the context menu
"Refactoring">"Override/Implement methods...", I've many successive dialog boxes
with the following error, before I can finally get the refactoring screen with
set's method names missing (see screenshot here
: http://img260.imageshack.us/img260/4625/pydevoverimplerrorhh1.png).
What do I do wrong ?
Problems occurred when invoking code from plug-in: "org.eclipse.jface".
