[gl4java-usergroup] Problems with textures and gl parameters

[Ricardo O. <ro...@gl...>]

I have a problem, I only can load textures in the display method, or in the
init, my aplication read a file  with urls of images, and I want to load
them when I read the text file, but I can't, it says me:
"GLUT : Warning in (unamed): GL error: operation not valid"

when I try to execute:
TextureLoader texLoader = new AWTTextureLoader(this,gl,glu);

If I execute this in the display function it works ok.

My question is: Only can execute this function inside display function and
init function?

I try to do this in the KeyPressed function, and I have the same problem.

If I change the parameters,like
:"gl.glPolygonMode(GL_FRONT_AND_BACK,GL_LINE);" in the KeyPressed function
This don't take effect.

I change a variable in Keypressed, and in display function I put the same
code, and works, I think it's the same problem, I only can do things of
opengl in Init or in display, it's correct?

Have this a solution?

Thank you
