Thread: Command Lines in OpenGL

I want to add a function into my program which lets the user change the ticket price and the show name, etc. things like that...

I can do all the background stuff, source code, but the key thing I don't know how to do, is set up so I can write to a command line in my program, using OpenGL....

Any insight on where to look for this? NeHe doesn't cover this topic :d

Assuming you mean in C++:

Code:

#include <iostream>

int main(int argc, char*argv[])
{
	for(register short int i=0;i<argc;i++)
	{
		std::cout<<i<<'\t'<<argv[i]<<'\n';
	}
	return 0;
}

and the input/output:

Code:

jshao@MCP ~/Programming/C++ $ ./test.exe a b c d
0       ./test.exe
1       a
2       b
3       c
4       d

as you can probably see, int argc holds how many command line arguments are sent (seperated by spaces). char*argv[] holds the actual arguments as character arrays

if your program was called on the command line, there's always at least one argument (argc>=1) and the first argument is always the title of the program/way it was invoked (argv[0]="./test.exe").

I believe Shamino meant a console (like hitting ~ in World of Warcraft) to type commands in. Theres source code under N at Nehe - NeHe Console by Lolo: http://nehe.gamedev.net/data/downloa...d.asp?letter=N

a Field? (e.g. the one I'm typing in now, e.g. the one you put url's in on browsers)

Yeah thats what he needs, I forgot OpenGL is just graphics commands/display (whatever).

Check my post, under OpenGL Addons, FLTK looks like nice one IMO: http://cboard.cprogramming.com/showt...8&page=2&pp=15
