[visionegg] Re: black screen

A common question:
set the parameter like so:
screen.parameters.bgcolor = (0.0, 0.0, 0.0, 0.0)

This is in the following demos:
az_el_grid.py
convert3d_to_2d.py
displayText.py
dots.py
dots_simple_loop.py
lib3ds-demo.py
makeMovie.py
makeMovie2.py
mouseTarget.py
mouseTarget_user_loop.py
multi_stim.py
put_pixels.py
quicktime.py
target.py

The code :
screen = get_default_screen()
generates a default Screen object
http://www.visionegg.org/reference/VisionEgg.Core.Screen-class.html

You can manipulate parameters of objects by referencing them with dot notation
MyObject.parameters.MyParameter

print MyObject.parameters.MyParameter
will print the value of the parameter

MyObject.parameters.MyParameter = NewValue
sets the parameter to a new value

Hi,

the construct

screen = get_default_screen()

creates a gray screen.  The reference documentation for the screen
class indicates that it has a bgcolor parameter.  I've tried a number
of ways to set it, without success.  How do we set this parameter?  I
want, bgcolor = (0.0, 0.0, 0.0), rather than the default gray.

Best, Darren
