Hi,
How can I change the logo of the openGL window opened?
Use a good OpenGL context creation library like SFML, or a better than GLUT library like SDL
The “logo” of the window completely depends on your window system. Not every system that offers an OpenGL(R) implementation has a concept of windows
with a titlebar or a keyboard for input.
The OpenGL(R) specification is only concerned with rendering. Creating a “window” or similar system dependend object and telling the operating system that
you want to do OpenGL(R) rendering is not part of OpenGL(R) and left as a task to the user. Operating Systems that offer OpenGL(R) rendering typically
have their own custom API for that.
You could use the operating/window system API yourself (e.g. WinAPI on Windows(R), Xlib on UNIX(R) with X11, etc…), or a library that handles the task for
you (GLFW, SFML, etc…).
Some of those libraries might have the neccessary abstract functions to set a logo asociated with a window.
