printing latitude on canvas

[oyuky]

hello, im trying to make a little script that prints the latitude on a canvas using a internal gps from a n95 phone , but im getting an unexpected behaivor, my app closes when it tries to print the latitude, any idea of what is going wrong here?


thanks

o.

here is the code:



from graphics import *
import appuifw
import e32
import positioning


appuifw.app.screen='normal'
appuifw.app.title=unicode('My Test App')
canvas=appuifw.Canvas()
appuifw.app.body=canvas


positioning.select_module(positioning.default_module())

positioning.set_requestors([{"type":"service",
"format":"application",
"data":"test_app"}])


d = positioning.position()
e = d["position"]


canvas.clear()
canvas.text( (2,12), str(e["latitude"]))

Hi Oyuky and welcome to the Python Forum !

Did you try print the latitude on the Console?

You could even use this to print any unicode texts when you are running your application,

t=appuifw.Text()
appuifw.app.body=t
t.add(unicode(variable_name))

PS: Use the CODE tabs (#) to post your CODE as I have done. This helps to maintain the indents in the code.

hello, thanks for the reply, yes, i forgot to convert to unicode. i was getting boxes in my canvas instead of numbers.

i added this and now it works fine

canvas.text( (2,12), unicode(str(e["latitude"])))
e32.ao_yield()
e32.ao_sleep(15)

bye
