Scale

To draw a simple scale you use gmw_scale, which returns if the scale is currently pressed(and maybe moving).

you can make the scale animated by using gmw_scale_anim, and passing an additional double pointer argument it will use for animations. The value of the scale is between 0 and 1, so you will have to convert and round to your own scale.

Gama automatically guesses if it is a horizontal or vertical scale by looking at it's dimensions.

# Examples

        int age = 0;
double scale_value = age / 100;
double scale_value_anim;

do {
    if(gmw_scale(0, 0, 0.5, 0.1, &scale_value)) {
        age = scale_value * 100; // update the age
    }
    // animated scale
    gmw_scale_anim(0, 0.3, 0.5, 0.1, &scale_value, &scale_value_anim);
} ...;
