(English) Grouped TableView Sample

(This entry is English translate of previous post.)
HelloPython, sample program of python on iPhone, is nice demonstration of how python code runs on iPhone. but I wanted more practical sample like this. (with some buttons, labels...)

so, I made one.

This uses TableView with GroupedStyle (UITableViewStyleGrouped).
To use, you can paste this code into HelloPython.py.

and in the middle of this code, there is "self.sections_" settings like this.

self.sections_ = [
{"header": "header 1", "items": [{"title": "title 1", "action": lambda p: self.callback(p)}]},
{"header": "header 2", "items": [
    {"title": "title 2-1", "action": None},
    {"title": "title 2-2", "action": None}]
}
]

You can configure the application by changing this settings. (clicking on "title 1" shows alert dialog by defalt.)

Enjoy iPhone programing.
