[fxruby-users] problem with FXMemoryBuffer and OpenGL

[Dr. Nikolaus Klepp]

Hi!

I just tried to migrate a program fom FOX 1.0 to FOX 1.2 and ran intgo this 
problem (ruby 1.8.2):

FXMemoryBuffer::data does not return an array of FXColor, but the same string 
I get when I call FXMemoryBuffer::to_s (it's 33 chars long). Despite 
FXMemoryBuffer::[] works and I can access the individual pixels. In 
consquence I can't access the bitmaps and can't build an OpenGL texture. 

example:

...
img = FXPNGImage.new(@@application, nil, IMAGE_KEEP|IMAGE_SHMI|IMAGE_SHMP)       
...
GL::TexImage2D(GL::TEXTURE_2D,0,GL::RGBA,img.width,img.height,0,GL::RGBA                                                                        
              GL::UNSIGNED_BYTE,img.data.to_s)
...

works using FOX 1.0, fails using FOX 1.2.

Any idea how to solve this?
