### Description
|
|
|
|
addch() adds the chtype ch to the default window (stdscr) at the
|
|
current cursor position, and advances the cursor. Note that chtypes
|
|
can convey both text (a single character) and attributes, including a
|
|
color pair. add_wch() is the wide-character version of this function,
|
|
taking a pointer to a cchar_t instead of a chtype.
|
|
|
|
waddch() is like addch(), but also lets you specify the window. (This
|
|
is in fact the core output routine.) wadd_wch() is the wide version.
|
|
|
|
mvaddch() moves the cursor to the specified (y, x) position, and adds
|
|
ch to stdscr. mvadd_wch() is the wide version.
|
|
|
|
mvwaddch() moves the cursor to the specified position and adds ch to
|
|
the specified window. mvwadd_wch() is the wide version.
|
|
|
|
echochar() adds ch to stdscr at the current cursor position and calls
|
|
refresh(). echo_wchar() is the wide version.
|
|
|
|
wechochar() adds ch to the specified window and calls wrefresh().
|
|
wecho_wchar() is the wide version.
|
|
|
|
addrawch(), waddrawch(), mvaddrawch() and mvwaddrawch() are PDCurses-
|
|
specific wrappers for addch() etc. that disable the translation of
|
|
control characters.
|
|
|
|
The following applies to all these functions:
|
|
|
|
If the cursor moves on to the right margin, an automatic newline is
|
|
performed. If scrollok is enabled, and a character is added to the
|
|
bottom right corner of the window, the scrolling region will be
|
|
scrolled up one line. If scrolling is not allowed, ERR will be
|
|
returned.
|
|
|
|
If ch is a tab, newline, or backspace, the cursor will be moved
|
|
appropriately within the window. If ch is a newline, the clrtoeol
|
|
routine is called before the cursor is moved to the beginning of the
|
|
next line. If newline mapping is off, the cursor will be moved to
|
|
the next line, but the x coordinate will be unchanged. If ch is a
|
|
tab the cursor is moved to the next tab position within the window.
|
|
If ch is another control character, it will be drawn in the ^X
|
|
notation. Calling the inch() routine after adding a control
|
|
character returns the representation of the control character, not
|
|
the control character.
|
|
|
|
Video attributes can be combined with a character by ORing them into
|
|
the parameter. Text, including attributes, can be copied from one
|
|
place to another by using inch() and addch().
|
|
|
|
Note that in PDCurses, for now, a cchar_t and a chtype are the same.
|
|
The text field is 16 bits wide, and is treated as Unicode (UCS-2)
|
|
when PDCurses is built with wide-character support (define PDC_WIDE).
|
|
So, in functions that take a chtype, like addch(), both the wide and
|
|
narrow versions will handle Unicode. But for portability, you should
|
|
use the wide functions.
|
|
|
|
### Return Value
|
|
|
|
All functions return OK on success and ERR on error.

/* The handling of "fullwidth" characters (those consuming two "normal"
|
|
columns) and combining characters (characters that can add accents to a
|
|
preceding character) in PDCurses is, of necessity, complex.
|
|
|
|
Unicode is defined to have 17 planes of 2^16 characters each, so that
|
|
the maximum Unicode code point is U+10FFFF. When addch() is given a
|
|
fullwidth character, it handles that character "normally", and then
|
|
stores the non-Unicode character DUMMY_CHAR_NEXT_TO_FULLWIDTH
|
|
(U+110000) next to it, just as a placeholder. (That part is actually
|
|
rather simple.)
|
|
|
|
PDCurses handles combining characters by creating entirely new "Unicode"
|
|
(let's call them "post-Unicode") characters, at code point U+110001
|
|
(COMBINED_CHAR_START) and beyond. The 'combos' table keeps track of
|
|
these newly-created characters, essentially saying: "This post-Unicode
|
|
character consists of the following 'root' character, plus an
|
|
added combining character." The 'root' character in question may itself
|
|
be a post-Unicode character; this allows us to add more than one
|
|
combining character.
|
|
|
|
For example, if one calls wchar() with, in succession, 'r' (U+72),
|
|
a circumflex (U+0302), and an acute accent below (U+317), the call
|
|
with the circumflex would cause 'combo' to be allocated, with
|
|
combo[0].root = 'r' and combo[0].added = 0x302. Code point U+110001
|
|
would correspond to this character ('r' plus circumflex). The call
|
|
with the acute accent below would create code point U+110002,
|
|
combo[1].root = 0x110001 and combo[1].added = 0x317. Thus, a character
|
|
with multiple combining characters simply resolves itself as a series
|
|
of "post-Unicode" characters. When the display function in pdcdisp.c
|
|
is asked to show character 0x110001 or 0x110002, it can use
|
|
PDC_expand_combined_characters() to convert that code point to the
|
|
actual series of characters.
|
|
|
|
'ncurses' handles combined characters in a very different manner: a
|
|
'cchar' is defined as an array of five characters, so that you can
|
|
add up to four combining characters in any given cell. I had to reject
|
|
that solution because backward compatibility within PDCurses would be
|
|
broken. Quite aside from that, this is a simpler solution, and allows
|
|
for any number of combining characters (though four ought to be enough
|
|
for anybody). */
