2006-07-24 23:39 fracpete

    Now uses less memory. A copy of the edited object is now returned (rather than the object itself) when getValue() is called. Previously, for example, fully built classifiers were copied to a backup variable when the OK button was pressed. This can quickly gobble up lots of memory when large data sets are being used.
gui/GenericObjectEditor.html (1.38.2.8)
