PyQt with embedded python in Qt App

Is it possible for a Qt C++ application, which embeds the python
interpreter, to import and use PyQt? There can be only one
QApplication, which is created in the C++ side, so how would I use
that from the python side?

QtGui.QApplication.instance()

QtGui.QApplication.instance()
What I can do with this pointer?
It is possible to add window to application ?
It is possible to connect to application signals?

It's not a pointer, it's a Python object that wraps the C++ pointer.

Yes.

Yes.

It's not a pointer, it's a Python object that wraps the C++ pointer.
So how to pass this object into embeded python interpreter (executed script)?
Anyone know any example?

You don't pass it, you _retrieve_ it in the embedded interpreter by
invoking the code given to you.

For better understand this :) I wan't add scripting to one application wrotten
with Qt.

So, you have Qt/C++ application which you want to script through
python.

But why do you need PyQt for ? If you design a script api in python
and bind it using whatever binding technology (manually, boost, sip,
pyrex, ...), you should not need to use PyQt.

Or do you mean to use PyQt as the binding technology ?

Or I want to use PyQt in scripts to have similar gui for plugins written in
python
Or I want to extend application by scripts with PyQt.

Or better question:
How to easy add python scripting in Qt application and have almast all objects
of app accesible in scripts?
Kross could be good solution?

I realy need some examples :(
I'm looking for solutions.

You are proffesional programmers so that is why write on this list :)

Thanks for Your answars.
