Hi, Stefan
We have some problems with declaration of singal inside of __init__ function. 1 - When you define the signal outside of __init__ function you are declaring the signal in the current class TYPE. If you declare the signal inside of __init__ function you are declaring the signal only for current instance. 2 - Signals in Qt is registered on metaobject, and we have only one metaobject for each type. Then you can't have individual signals/slot for each instance. 3 - PySide register the signal/slot/properties on metaobject during the QObject constructor, based on the class TYPE information, and if everything works fine the object Signal is transfered to instance object with all information necessary to connect/emit/get/set. Because of that you can't declar the Signal, Slot, Property for individual instance object.
