Hello, I´ve a problem when I try to draw a line in my app for a s60 mobile. I try this:


import e32
import appuifw
import graphics
import key_codes
import random
...
img.text((180, 200), u'%d' % (3))
img.line((30,40),(100,40),outline=0,fill=0)
...

and I´ve tried the second line in a great amount of ways and i become once and again the same error: Invalid syntax. When I quit the second line it all works fine. What am I doing wrong?

Thanks!

That's because the coordinates are supposed to be in one tuple. So use either
img.line((30,40,100,40),outline=0,fill=0)
or
img.line(((30,40),(100,40)),outline=0,fill=0)

Hi BAM8,
If would like to tell you that please give a complete code here so that one can easily find the error and one more thing, use code tag while writing a code so that it will maintain all white spaces. It is given as a '#" button on the top of the window.

Regards.

I tried that too, and the way i put here too... all of them give me a mistake.
