Re: Ncurses/Forms unfocus current field

[Leon Winter]

Hi Thomas,

> yes - that would help

see attached patch for the new function "unfocus_current_field".
I'd like to reiterate that some programs might assume that the current field
pointer is always valid [0][1][2] (just a small search for code samples of
usages). However in order to set the field pointer to NULL one has to
deliberately do so. When we introduce the new function and people use it, they
need to make sure their logic can handle a NULL pointer for the current field.

Regards,
Leon
