I need to give user ability to enter a time in form hh:mm:ss (with appropriate validation of course). And standard function appuifw.query(u'Label', 'time') works almost fine except that it allows to enter only hours and minutes (hh:mm). So I want to look though its source and write my own that allows to enter seconds as well.
I've found file epoc32\winscw\c\resource\appuifw.py that comes with PyS60 SDK extension but it only contains constructor implementation (__init__).
So the question is where to find sources of platform's standard functions (particularly appuifw.query).
Thanks in advance.
