<H2>DESCRIPTION</H2><PRE>
|
|
Calling <STRONG>newwin</STRONG> creates and returns a pointer to a new win-
|
|
dow with the given number of lines and columns. The upper
|
|
left-hand corner of the window is at
|
|
line <EM>begin</EM>_<EM>y</EM>,
|
|
column <EM>begin</EM>_<EM>x</EM>
|
|
|
|
If either <EM>nlines</EM> or <EM>ncols</EM> is zero, they default to
|
|
<STRONG>LINES</STRONG> <STRONG>-</STRONG> <EM>begin</EM>_<EM>y</EM> and
|
|
<STRONG>COLS</STRONG> <STRONG>-</STRONG> <EM>begin</EM>_<EM>x</EM>.
|
|
|
|
A new full-screen window is created by calling
|
|
<STRONG>newwin(0,0,0,0)</STRONG>.
|
|
|
|
Calling <STRONG>delwin</STRONG> deletes the named window, freeing all memo-
|
|
ry associated with it (it does not actually erase the win-
|
|
dow's screen image). Subwindows must be deleted before
|
|
the main window can be deleted.
|
|
|
|
Calling <STRONG>mvwin</STRONG> moves the window so that the upper left-hand
|
|
corner is at position (<EM>x</EM>, <EM>y</EM>). If the move would cause the
|
|
window to be off the screen, it is an error and the window
|
|
is not moved. Moving subwindows is allowed, but should be
|
|
avoided.
|
|
|
|
Calling <STRONG>subwin</STRONG> creates and returns a pointer to a new win-
|
|
dow with the given number of lines, <EM>nlines</EM>, and columns,
|
|
<EM>ncols</EM>. The window is at position (<EM>begin</EM>_<EM>y</EM>, <EM>begin</EM>_<EM>x</EM>) on
|
|
the screen. The subwindow shares memory with the window
|
|
<EM>orig</EM>, so that changes made to one window will affect both
|
|
windows. When using this routine, it is necessary to call
|
|
<STRONG>touchwin</STRONG> or <STRONG>touchline</STRONG> on <EM>orig</EM> before calling <STRONG>wrefresh</STRONG> on
|
|
the subwindow.
|
|
|
|
Calling <STRONG>derwin</STRONG> is the same as calling <STRONG>subwin,</STRONG> except that
|
|
<EM>begin</EM>_<EM>y</EM> and <EM>begin</EM>_<EM>x</EM> are relative to the origin of the win-
|
|
dow <EM>orig</EM> rather than the screen. There is no difference
|
|
between the subwindows and the derived windows.
|
|
|
|
Calling <STRONG>mvderwin</STRONG> moves a derived window (or subwindow) in-
|
|
side its parent window. The screen-relative parameters of
|
|
the window are not changed. This routine is used to dis-
|
|
play different parts of the parent window at the same
|
|
physical position on the screen.
|
|
|
|
Calling <STRONG>dupwin</STRONG> creates an exact duplicate of the window
|
|
<EM>win</EM>.
|
|
|
|
Calling <STRONG>wsyncup</STRONG> touches all locations in ancestors of <EM>win</EM>
|
|
that are changed in <EM>win</EM>. If <STRONG>syncok</STRONG> is called with second
|
|
argument <STRONG>TRUE</STRONG> then <STRONG>wsyncup</STRONG> is called automatically whenev-
|
|
er there is a change in the window.
|
|
|
|
The <STRONG>wsyncdown</STRONG> routine touches each location in <EM>win</EM> that
|
|
has been touched in any of its ancestor windows. This
|
|
routine is called by <STRONG>wrefresh</STRONG>, so it should almost never
|
|
be necessary to call it manually.
|
|
|
|
The routine <STRONG>wcursyncup</STRONG> updates the current cursor position
|
|
of all the ancestors of the window to reflect the current
|
|
cursor position of the window.
|
|
|
|
|
|
</PRE>
|
|
<H2>RETURN VALUE</H2><PRE>
|
|
Routines that return an integer return the integer <STRONG>ERR</STRONG> up-
|
|
on failure and <STRONG>OK</STRONG> (SVr4 only specifies "an integer value
|
|
other than <STRONG>ERR</STRONG>") upon successful completion.
|
|
|
|
Routines that return pointers return <STRONG>NULL</STRONG> on error.
|
|
|
|
X/Open defines no error conditions. In this implementa-
|
|
tion
|
|
|
|
<STRONG>delwin</STRONG>
|
|
returns an error if the window pointer is null, or if
|
|
the window is the parent of another window.
|
|
|
|
<STRONG>derwin</STRONG>
|
|
returns an error if the parent window pointer is
|
|
null, or if any of its ordinates or dimensions is
|
|
negative, or if the resulting window does not fit in-
|
|
side the parent window.
|
|
|
|
<STRONG>dupwin</STRONG>
|
|
returns an error if the window pointer is null.
|
|
|
|
This implementation also maintains a list of windows,
|
|
and checks that the pointer passed to <STRONG>delwin</STRONG> is one
|
|
that it created, returning an error if it was not..
|
|
|
|
<STRONG>mvderwin</STRONG>
|
|
returns an error if the window pointer is null, or if
|
|
some part of the window would be placed off-screen.
|
|
|
|
<STRONG>mvwin</STRONG>
|
|
returns an error if the window pointer is null, or if
|
|
the window is really a pad, or if some part of the
|
|
window would be placed off-screen.
|
|
|
|
<STRONG>newwin</STRONG>
|
|
will fail if either of its beginning ordinates is
|
|
negative, or if either the number of lines or columns
|
|
is negative.
|
|
|
|
<STRONG>syncok</STRONG>
|
|
returns an error if the window pointer is null.
|
|
|
|
<STRONG>subwin</STRONG>
|
|
returns an error if the parent window pointer is
|
|
null, or if any of its ordinates or dimensions is
|
|
negative, or if the resulting window does not fit in-
|
|
side the parent window.
|
|
|
|
The functions which return a window pointer may also fail
|
|
if there is insufficient memory for its data structures.
|
|
Any of these functions will fail if the screen has not
|
|
been initialized, i.e., with <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG>.

|
|
<H2>NOTES</H2><PRE>
|
|
If many small changes are made to the window, the <STRONG>wsyncup</STRONG>
|
|
option could degrade performance.
|
|
|
|
Note that <STRONG>syncok</STRONG> may be a macro.
|
|
|
|
|
|
</PRE>
|
|
<H2>BUGS</H2><PRE>
|
|
The subwindow functions (<EM>subwin</EM>, <EM>derwin</EM>, <EM>mvderwin</EM>, <STRONG>wsyn-</STRONG>
|
|
<STRONG>cup</STRONG>, <STRONG>wsyncdown</STRONG>, <STRONG>wcursyncup</STRONG>, <STRONG>syncok</STRONG>) are flaky, incomplete-
|
|
ly implemented, and not well tested.
|
|
|
|
The System V curses documentation is very unclear about
|
|
what <STRONG>wsyncup</STRONG> and <STRONG>wsyncdown</STRONG> actually do. It seems to imply
|
|
that they are only supposed to touch exactly those lines
|
|
that are affected by ancestor changes. The language here,
|
|
and the behavior of the <STRONG>curses</STRONG> implementation, is pat-
|
|
terned on the XPG4 curses standard. The weaker XPG4 spec
|
|
may result in slower updates.
|
|
|
|
|
|
</PRE>
|
|
<H2>PORTABILITY</H2><PRE>
|
|
The XSI Curses standard, Issue 4 describes these func-
|
|
tions.
