Hello I have set my app for SDL and CEGUI i have put some events to fire . like when pushing a button drawing a square or tea pot. my code is like this Code: bool DrawSquare(const CEGUI::EventArgs &e) { glutDisplayFunc(dene); return true; } and the dene function is Code: void dene() { glutWireTeapot(3.2) } what may be the problem ? when i click draw square it crashes without any warning and in debug it doesnt seem to show me where the problem is

OK a couple of things:
You seem to be using SDL and glut when there will more than lightly be a conflict using both of these.
You have not provided enough information for anybody to suggest a solution.
Have you tried debugging the application?
You have already posted this to the CEGUI forum.

yes i have

sorry if i didnt give enough info

ok here's the thing


since i cant find any function to draw lines with SDL

this is the code where i initilise SDL

void setupSDL()
{

if ((SDL_Init(SDL_INIT_VIDEO))<0)
{
fprintf(stderr, "Unable to initialise SDL: %s", SDL_GetError());
exit(0);
}

if ((surface = SDL_SetVideoMode(800,600,0,SDL_OPENGL))==NULL)
{
fprintf(stderr, "Unable to set OpenGL videomode: %s", SDL_GetError());
SDL_Quit();
exit(0);

}


SDL_WM_SetCaption("CSE452 Paint Program", NULL);

//Draw_Line(surface, 100,100, 30,0, 3);

//gluLookAt(100, 0, 20, 0, 0, -1, 0, 1, 0);
glEnable(GL_CULL_FACE);

glDisable(GL_FOG);

glClearColor(.2f,.3f,.3f,1.0f);



//glViewport(0,0, 800,600);

SDL_ShowCursor(SDL_DISABLE);

SDL_EnableUNICODE(1);


}


i was thinking if i may have the camera position wrong.
btw i found a SDL_draw library im trying to get it work right now. but its stubborn.
