Most pyglet programs seem not to work for me, example: 'Hello World' (Pyglet 1.1)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. 'Hello World' Example does not work. (copyed and pasted
http://pyglet.org/doc/programming_guide/hello_world.py)
2. Leaves a white window that can't be closed.
3. Most other Examples I tried lead to the same issue.

Paste in the traceback or error message:

Any additional info (platform/language/hardware) that may be relevant?

I am new to programming. I just tried this out, if it's my fault it doesn't
work, I am sorry.

Hi, that's an unusual error.  I assume you can run the examples that do not 
render text (for example, opengl.py)?  
Please post the output of running (e.g., from cygwin or a command line) "python 
-m pyglet.info", which will give 
me some more information about your system.  If you're running the examples 
from IDLE or another IDE, it is 
worth trying just from the command line (or from explorer).

Yes, I can run "opengl.py" from the pyglet 1.1-docs examples. I think you are 
right,
it must have something to do with text rendering.

I don't know if this will help you in any way, but I just noticed that you 
released

Thanks, could you try adding the following line near the top of your test 
program?

import pyglet.image.codecs.gdiplus

Let me know if this fixes the problem so I can add a proper fix.

It should work if you avoid GDI+.  Add the following line before any other 
imports:

import pyglet
pyglet.options['font'] = 'win32'

This uses a different font rendering engine in Windows (which should at least 
be legible, if not pretty).  Please 
confirm that you have XP service pack 2 and subsequent updates installed.

Yes, service pack 2 and updates are installed.

Hrm, the non-GDI+ font rendering code is deprecated, which is why you can 
expect to see a few errors like this.  
For now, just explicitly pass in a font name (e.g., 'Arial').

Original comment by Alex.Hol...@gmail.com on 28 Aug 2008 at 11:39

This is a long shot, but you might also want to try (without the PYGLET_FONT 
environment variable set) changing 
pyglet/font/win32.py line 531 from

        name = ctypes.c_wchar_p(name)

to 

        name = ctypes.create_unicode_buffer(name)

OK, I want to make sure I do everything right.
I changed the line in win32.py, ok.

But what is the PYGLET_FONT environment varaible?

This is the program I run:

__docformat__ = 'restructuredtext'
__version__ = '$Id: hello_world.py 2090 2008-05-29 12:49:25Z Alex.Holkner $'

window = pyglet.window.Window()
label = pyglet.text.Label('Hello, world', 
                          font_name='Arial', 
                          font_size=36,
                          x=window.width//2, y=window.height//2,
                          anchor_x='center', anchor_y='center')

@window.event
def on_draw():
    window.clear()
    label.draw()

Right, just delete the line 

pyglet.options['font'] = ('win32',)

which disables GDI+ rendering (and wouldn't really solve the issue anyway).

I realize that "me too" posts are inappropriate, however I am having an almost 
identical issue as this person, and I cannot help but notice that we are both 
using 
non-English versions of Windows. This has caused issues for me in the past, and 
I 
wonder if perhaps that is the case here as well.

Just to see if this makes any difference. Thanks!
