Once a form has been posted (displayed), you should funnel
input events to it through <STRONG>form_driver</STRONG>. This routine has
three major input cases:
- - The input is a form navigation request. Navigation
- request codes are constants defined in <STRONG><form.h></STRONG>, which
- are distinct from the key- and character codes returned
- by <STRONG>wgetch</STRONG>.
+ <STRONG>o</STRONG> The input is a form navigation request. Navigation
+ request codes are constants defined in <STRONG><form.h></STRONG>, which
+ are distinct from the key- and character codes
+ returned by <STRONG>wgetch</STRONG>.
- - The input is a printable character. Printable charac-
- ters (which must be positive, less than 256) are
- checked according to the program's locale settings.
