DESCRIPTION
A spin button is a composite widget, it consists of an
entry and a scroll button. A spin button is used to cycle
through a series of string type inputs. The value is con-
troled by a spin function of type
char *(func)(int old_idx, int new_idx, void *clientData);
When the left mouse button is pressed over the arrow button,
the spin function b+func+ will be called to compute the
next choice. The value will then be displayed in the entry
widget.
EZ_GetSpinButtonValue returns the current value of
a spin button.
