NAME
       adime_d_double_calc_edit_proc

SYNOPSIS
       #include <adime.h>


       int adime_d_double_calc_edit_proc(int msg, DIALOG *d, int c);

DESCRIPTION
       Gui proc for an edit box accepting a mathematical expression whose result
       is a floating point number. The result is calculated and displayed on a
       separate gui object as the user types. The edit box has a 3d-ish look.

       The dp2 field points to a `struct ADIME_EDIT_NUMBER *´ which holds some
       information about the behavior of the edit box:

          typedef struct ADIME_EDIT_NUMBER
          {
             int is_signed;          /* Set for integer formats if it is signed. */
             int is_float;           /* Set if we only have float, not double. */
             double min_val, max_val;/* Range for numbers. */
             DIALOG *result_object;  /* DIALOG object to display result in. */
          } ADIME_EDIT_NUMBER;

       The `result_object´ will be used to display the result of the expression.
       There is an `adime_d_calc_edit_result_proc´ object type which is designed
       to be used as `result_object´, but you may of course write your own
       object to take care of this. Whenever the user changes the text in the
       `adime_d_double_calc_edit_proc´, the result is printed to the `dp´ field
       of `result_object´; hence you must have set the dp field of
       `result_object´ to a text buffer with enough space (256 bytes is safe).
       The `result_object´ will then be sent a `MSG_DRAW´ message with the `c´
       parameter set to 2 if there is an error in the expression or 1 if it is
       ok.
