[Qgis-developer] Open custom form from another form

[Luca Lanteri]

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
