Subject: PyqtProperty types


Hi,


Two questions about pyqtProperties:


1) When making plugins for QtDesigner, I expose them in the widget class escope with QtCore.pyqtProperty, passing as parameters the type of the property and functions to get and set, for example:


my_property = pyqtProperty('QString', getMyProperty, setMyProperty, None)


However, this time I would like to use types as int and float. Every time I try I got errors like this:


"TypeError: unable to convert a Python 'str' object to a C++ 'double' instance"


What is the correct way to define types different from QString?


2) How can I create a property which is composed by others? An example of this kind is the property geometry of QWidget class: it is composed by X, Y, Width and Height properties.


Thanks for any help! :)
