[PyQt] Custom widgets in Qt5

[Vincent Vande Vyvre]

Hi,

With PyQt4 I have this folder:
/usr/lib/x86_64-linux-gnu/qt4/plugins/designer/
wich content the lib libpythonplugin.so and a subfolder python for my 
custom widgets.

Now, I've just installed Qt5 and the latest snapshots of SIP and PyQt5 
and I'm looking whee can I copy my own widgets.
I've found a folder:
/usr/lib/Qt5.0.2/5.0.2/gcc_64/plugins/designer
but without the lib libpythonplugin.so, I presume this lib is needed for 
the widgets written in Python.

So, it's an other place for theses plugins or it's not already supported 
in PyQt5 ?
