OpenGL with wxWidgets
by Chris Perez 23 Feb '07

Ok, Brand new problem, I have OpenGL working in Haskell and compiling, and I have been working with wxWidgets to make the GUI process easier. Now I am trying to work out a way to combine the two. I haven't been able to do it successfully because they seem to create different kinds of windows, but I would like it if it would be possible to Open a frame with wxWidgets then inside the frame as one of the panels Have some OpenGL running , on which I could apply buttons from the parent frame to. I can't seem to find any easy way to do this and have been reading through the documentation for both. Any suggestions? -- Without Wax, Chris

clear [ColorBuffer]

Hello, The program: import Graphics.Rendering.OpenGL import Graphics.UI.GLUT main = do _ <- getArgsAndInitialize createWindow "Hello World" displayCallback $= clear [ ColorBuffer ] mainLoop and the problem: The ColorBuffer is not cleared, the window shows what was there before it was created. Creating windows, drawing points,... works all well, but "clear [ ColorBuffer ]" seems not to work. (I'm using the ghc 6.6 on Windows) Thanks in advance for your help.

HOpenGL install help

Hello, I am writing a graphical program in Haskell as a final project for university to show that it is not a "toy language". Unfortunatly when trying to install HOpenGL I get past the ./configure part but then fail with errors on the make depend and make all or even make install. I can't seem to locate the problem or where the errors are coming from. I get the following error report: module 'Main' is defined in multiple files: Info.hs QBSP.hs QuakeMovement.hs TestGLUT.hs make[2]: *** [depend] Error 1 make[1]: *** [depend] Error 1 make: *** [depend] Error 1 I would really like to use HOpenGL for this project, so If anyone knows how I can solve this I would love to know. -- Without Wax, Chris
