I'm having trouble finding example code that uses Regions in the
Haskell Graphics Library. But the following gives me a black window
when I think it should give me a black window with a square in it:
------------------ START CODE ------------------------------------------
import Graphics.HGL
main = runGraphics test
test = do
w <- openWindow "Test" (100,100)
drawInWindow w $ withRGB (RGB 255 255 255) testRegion
getLBP w
closeWindow w
testRegion = regionToGraphic $ rectangleRegion (5,5) (30,30)
------------------ END CODE ------------------------------------------
Am I using it correctly? If I am, then any other help is greatly appreciated.
I am on Debian Squeeze using GHC 6.12.1 (thanks debian maintainers!),
and using HGL-3.2.0.2
Thanks,
Brandon Simmons
