Mouse scroll wheel (glut)

Recommended Posts

Hello, so I am trying to utilize the scroll wheel of the mouse in my program. here is my code:

void mouse(int button, int state, int x, int y)
{
cout<< "It's Happening" << endl;

if (state == GLUT_UP )
{
if ( button == GLUT_WHEEL_UP )
{
cout<< "Wheel Up" << endl;
gameCamera.zoom(GLUT_WHEEL_UP);
}
else if( button == GLUT_WHEEL_DOWN )
{
cout << "Wheel Down" << endl;
gameCamera.zoom(GLUT_WHEEL_DOWN);
}
}
}

The function is called ("It's happening is printed") whenever i click and what not, but it does nothing when I try to scroll. Is there a way to use scrolling with glut? if not, what is another option? It'd be nice if I didn't have to include another library or anything.

As a not i've defined

#if !defined(GLUT_WHEEL_UP)
# define GLUT_WHEEL_UP 3
# define GLUT_WHEEL_DOWN 4
#endif

at the top of the program. But it doesnt really matter because the function isn't even calling then you scroll at all.

Hello,

I use freeglut on linux and find that it doesn't support scroll wheel.
There is no define of GLUT_WHEEL_UP and GLUT_WHEEL_DOWN.
So try other libraries such as SDL, SFML and QT.
