Hi Luca,
The best way to do this, is to set your personnally designed UI file in
the layer properties->field properties->attribute editor layout->provide
ui file
Then, you want to call qgis method to show a feature form:
http://qgis.org/api/classQgisInterface.html#aff2467aa3cefd8fc5b59213f385b7180
And you would need some processing to show it:
1. get feature id from the selected line
2. fetch the feature of the main layer
3. get the foreign key from one of its fields
4. fetch the corresponding feature
4. show the feature form with it
Anyway, if I understand properly, you're trying to do something which
has been recently added to QGIS (it's in the master version), it's 1:n
relations.

Hi to all,
I need a help from a python guru. I'm trying to move my first steps
with pyqgis.
I've got two qgis layer with a 1 to many relation. I create a custom
form for the parent layer with a QTableWidget that contain the primary
key of the child layer. Now I want to open another custom form with
the data of the child record selected into the QTableWidget. I try to
look up into the QGIS API Documentation but I'didn't find the solution
to my problem.
Now I just can open form with this code, connected with a button:
path = os.path.dirname( os.path.abspath( __file__ ) )
uifile = os.path.join(path , my_form.ui')
window = uic.loadUi(uifile)
window.exec_()
how can I connect my form with the right data ?
Can I use some method to select the right layer/record and open it in
the form ?
Thanks in advance for any tips
Luca
