#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 dis‐
played 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 expres‐
sion. 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.
