Important versions about opaque WINDOW

5.6 (20070303)

add NCURSES_OPAQUE symbol

5.7 (20090906)

add is_pad() function

• Non-opaque

  • WINDOW_HAS_FLAGS is defined
  • NCURSES_OPAQUE is defined as zero or not defined

• Opaque

  • WINDOW_HAS_FLAGS is not defined
  • NCURSES_OPAQUE is defined as one

Current

• define always WINDOW_HAS_FLAGS when having ncurses.h
• check directly _flags field of WINDOW

ncurses	non-opaque	opaque
< 5.6 (20070303)	ok	not implemented
>= 5.6 (20070303)	ok	compile error

Use is_pad

• define always WINDOW_HAS_FLAGS when having ncurses.h
• define py_is_pad if having _flags field or is_pad function/macro
• call py_is_pad

ncurses	non-opaque	opaque
< 5.6 (20070303)	ok	not implemented
>= 5.6 (20070303)	ok	compile error
>= 5.7 (20090906)	ok	ok

Use is_pad + Removing overwrite of WINDOW_HAS_FLAGS definition

• define py_is_pad if having _flags field or is_pad function/macro
• call py_is_pad

ncurses	non-opaque	opaque
< 5.6 (20070303)	ok	not implemented
>= 5.6 (20070303)	ok	retrograde
>= 5.7 (20090906)	ok	ok

PR 1689

• define NCURSES_OPAQUE as zero if both HAVE_CURSES_IS_PAD and WINDOW_HAS_FLAGS aren't defined
• define py_is_pad if having _flags field or is_pad function/macro
• call py_is_pad

ncurses	non-opaque	opaque
