i need a program(code) for drawing using openGL.

example: when i click the left button of the mouse to start drawing something... and when i click the right button of the mouse to drop down a menu with colors, so i can choose a color to draw with...

I found something for the mouseHandler() that does the freehand drawing, and i tried to use it, but it's not working.

here is the func

void mouseHandler(int mouseX, int mouseY) {     GLint x = mouseX;     GLint y = 640 - mouseY;  //note mouse origin is bottom     GLint brushSize = 20;     glColor3f(1.0,0.0,0.0);     glRecti(x, y, x+brushSize, y+brushSize);     glFlush(); }


any help would be appreciated. thanks
