Label formatting issue when using Python 3 on Pyglet 1.2 RC1 #774

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Install Pyglet version 1.2 RC1
2. Create a script based on the tutorial from the pyglet programming guide. 
Found here: http://www.pyglet.org/doc/programming_guide/hello_world.html
3. Run the script using Python 3.

I have tried running this script in both Python 2 and Python 3. Python 2 runs 
everything just fine while 3 just loads up a black window and crashes before 
the Label is drawn.

Paste in the traceback or error message (this was produced when running each 
line of the script in the Python3 interpreter):

>>> label = pyglet.text.Label('Hello World', font_name = 'Times New Roman', 
font_size = 10, x = window.width//2, y = window.height//2, anchor_x = 'center', 
anchor_y = 'center')
