1.1.0 pre-alpha version released

[jplauril]

So, the 1.1.0 pre-alpha version is out there. Try it if you are interested.

Note that the API's aren't final and that the 1.1.0 build is actually already quite old, since posting it took a while. The much improved 1.1.2 build will hopefully follow soon.

[korakotc]

Thank you!!!

Worth my patient wait.

[Zen13546]

Great, been waiting for it such a long time ...

First I noticed was that I downloaded version for S60 v1.1, and it wasn't able to install, so I tried 2.0 and it worked (I use n-gage -> 1.1), so please fix it, it may confuse somebody.

[Zen13546]

it's great, but one thing. are you sure that appuifw.Text.color, font, hlcolor and style should work? I can change anything, but the font (color, style...) is still the same. I don't know if I'm doing something wrong or it's a pre-alpha-bug.

I am only able to download the SIS file from the forum.nokia.com website. The zip files that are downloaded are corrupt. I need those since I don't have a phone at hand to test the new API's. Anybody else experiencing the same problem?

[korakotc]

Thanks for the cube example. It make playing with
the canvas much easier. The snake example
is a bit too long.

I added 4 lines to the cube.

def stop():
....global xrd, zrd
....xrd = zrd = 0
c.bind(EKeyDevice3, stop)

Now, you can stop the cube with the joy stick.
(Does anyone know why its name is Device3 ?)

[korakotc]

I post 3 examples about contacts, canvas and sysinfo
at the code snippet repository.
http://www.bigbold.com/snippets/tags/series60

My canvas example is a bit shorter, and could be
a good start to play with canvas.

Currently it looks like pages don't allow anykind of downloads. Lets wait until Forum gets thing fixed and try then again

Could you post the code that doesn't work?

Note that those attributes only apply to new text you insert, they won't affect the current contents in any way.

sorry. I had written the example when I downloaded the new SDK, and it didn't work. But I deleted it, and now when I read your post, I tried to write some example again, and it worked. I can't compare it with the previous code so I don't what did I wrong.

Sorry.

Nice example, Cyke64

Let's collect some more ideas.
What other easy examples should we write
to demonstrate canvas?

Now we have snake and rotate_cube.
Here are my ideas
- hang man : use draw & text
- mine sweeper
- 15-square (1 missing)

Any more ideas?

[mueller-stach]

The rotating cube is really nice, thanks. For real nerds here is the rotating icosahedron:


Replace con and cpx data in cube example by the following: (import math !)

s=72
h=s//2*(math.sqrt(5)-1)

cpx=((-h,-s,0),(h,-s,0),
(0,-h,s),(0,-h,-s),(s,0,h),
(s,0,-h), (-s,0,-h),(-s,0,h),(0,h,s),
(0,h,-s),(-h,s,0),(h,s,0))

con = ((0,1),(1,2),(2,0),
(1,3),(3,0),(1,4),
(4,5),(5,1),(0,6),
(6,7),(7,0),(2,8),
(2,4),(2,7),(3,5),
(3,6),(8,7),(8,4),
(3,9),(9,6),(6,10),
(7,10),(9,5),(5,11),
(4,11),(11,8),(8,10),
(10,9),(9,11),(10,11))
