NAME

       d_check_proc  - Dialog procedure implementing a check box object. Allegro game programming
       library.

SYNOPSIS

       #include <allegro.h>

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

DESCRIPTION

       This is an example of how  you  can  derive  objects  from  other  objects.  Most  of  the
       functionality comes from d_button_proc(), but it displays itself as a check box. If the d1
       field is non-zero, the text will be printed to the right of the check, otherwise  it  will
       be on the left.

       Note:  the object width should allow space for the text as well as the check box (which is
       square, with sides equal to the object height).
