X.SH DESCRIPTION
X.I Textedit
Xis the standard text-editing package for STDWIN.
XIt allows you to designate any part of a window as a ``text-editing''
Xarea, in which the user can see or edit arbitrary text.
XUntil I find the time and the mental rest to write a decent manual,
Xyou'll have to do with the example and hints on this man page.
X.PP
XA textedit area need not occupy an entire window, and there can be
Xmore than one textedit area in a given window.
XConsequently, textedit areas are not resized automatically when their
Xwindow is resized, and the document size is not set automatically when
Xthe textedit area's size changes.
XIf you want to use a single textedit area in a window, and want them to
Xbe coupled more tightly, use the
X.I editwin
Xpackage instead.
X.PP
XThe functions
X.I wdrawpar
Xand
X.I wparheight
Xdraw a paragraph of text exactly like the
X.I textedit
Xroutines would draw it, without the need to allocate a textedit data
Xstructure for it.
X.I Wdrawpar
Xreturns the ``v'' coordinate of the bottom of the paragraph drawn, and
X.I wparheight
Xreturns its height.
X.PP
XAvailable routines are:
X.IP tealloc
X.IP tecreate
X.IP tefree
X.IP tedestroy
X.IP tedraw
X.IP tedrawnew
X.IP temove
X.IP temovenew
X.IP tesetfocus
X.IP tereplace
X.IP tesetbuf
X.IP tearrow
X.IP tebackspace
X.IP teclicknew
X.IP tedoubleclick
X.IP teevent
X.IP teclick
X.IP teclickextend
X.IP tegettext
X.IP tegetlen
X.IP tegetnlines
X.IP tegetfoc1
X.IP tegetfoc2
X.IP tegetleft
X.IP tegettop
X.IP tegetright
X.IP tegetbottom
X.IP wdrawpar
X.IP wparheight

X.SH HINTS
X.I Tedestroy
Xcalls
X.I wchange
Xfor the area occupied by the textedit area, and then calls
X.IR tefree ;
X.I tefree
Xgets rid of the data structures allocated for it.
X.PP
X.I Tesetbuf
X``gives the buffer away.''
XThat is, you should have allocated the buffer using
X.IR malloc (3),
Xbut you shouldn't call
X.I free
Xto get rid of it \- a pointer to the buffer is incorporated in the
Xtextedit data structures, and it will be freed later by
X.I tefree.
XDon't pass a buffer that wasn't allocated through
X.IR malloc (3)!
X.PP
X.I Tegettext
Xreturns a pointer to the internal buffer used to represent the text.
XSubsequent calls to textedit routines that modify the buffer may
Xinvalidate this pointer.
XYou shouldn't modify the text found there.
XTo get the text selected in the focus, copy the substring found between
Xpositions
X.I tegetfoc1
Xand
X.I tegetfoc2,
Xfor example:
X.nf
X.ft C
X/* Copy focus text into buffer, whose size is len */
Xgetfocus(tp, buf, len) TEXTEDIT *tp; char *buf; {
X int f1= tegetfoc1(tp), f2= tegetfoc2(tp);
X char *text= tegettext(tp);
X if (f2-f1 < len) len= f2-f1+1;
X strncpy(buf, len-1, text+f1);
X buf[len-1]= '\0';

XTextedit areas always grow and shrunk automaticatically at the bottom.
XTherefore,
X.I tecreate
Xignores the bottom coordinate.
X.br
XWhen a textedit area shrinks more than a line at a time, garbage may
Xremain on the screen between the old and the new bottom position.
X.br
XThe text attributes (font, size and style) in effect when any of the
Xtextedit routines are called must be those that were in effect when the
Xtextedit area was created. (The routines should save and restore the
Xtext attributes, but currently they don't.)
X.br
XThe constants TRUE and FALSE used in the #include file are not defined
Xthere, even though the typedef bool is.
X.br
XBeware that the last argument to
X.I tealloc
Xand
X.I temove
Xis the width of the textedit area on the screen, not its right
Xcoordinate!
X.br
XIt is a pain that there are ``new'' and ``old'' versions of routines
Xlike tealloc, tedraw, temove and teclick.
XThe old routines should not be used any more, and the new ones should be
Xrenamed to the old names.
X.br
X.I Wdrawpar
Xand

XMissing functionality:
Xa way to affect the line breaking algorithm;
Xa way to display text centered or with justified margins;
Xa way to disable changes while still passing events (for selection, etc.);
Xmore keyboard editing functions (begin/end of line/file, etc.);
Xa way to suppress the automatic growing of the textedit area;

X.SH DESCRIPTION
X.I VT
Xis a package which emulates one or more virtual terminals in STDWIN
Xwindows.
XA VT structure contains a WINDOW pointer and data structures to save the
Xscreen contents, cursor position, etc.
XSuch a virtual terminal may be used to implement a terminal emulation
Xprogram on a micro-computer (which was the original goal of this
Xprogramming exercise), or as a tool to simplify interfacing a program
Xusing printf-style output to STDWIN.
XThe virtual terminal's cursor position is indicated by STDWIN's standard
Xtext caret, appearing to the left of the character at the cursor
Xposition.
XThis actually feels very natural in most cases.
X.PP
XThe functions you might want to know about are:
X.IP vtopen
XCreates the window and returns a pointer to a VT struct.
X.I Rows
Xand
X.I cols
Xspecify the size of the virtual terminal;
X.I saverows
Xspecifies the number of rows saved after they have scrolled off the top
Xof the terminal.
XIf something went wrong, a nil pointer is returned.
X.IP vtclose
XCloses the window and deallocates the data contained in the VT struct.
X.IP vtansiputs
XSends an output string to the virtual terminal.
X.I Len
Xspecifies the length of the string; if it is negative, the string is
Xterminated by a null character.
XControl character and escape sequence processing is done in the style of
XANSI terminals, with some limitations and extensions.
XWarning: unless
X.I "vtsetnlcr(vt, 1)"
Xhas been called, both a CR and LF character must be sent to properly
Xstart a new line.
X.IP vtsetcursor
XMoves the terminal's cursor to the indicated position.
XThe top left corner of the virtual terminal is position (0, 0).
X.IP vtreset
XCompletely resets the virtual terminal to its initial state.
XThe cursor is moved to position (0, 0).
XThe
X.I lazy
Xand
X.I nlcr
Xflags are not changed.
X.IP vtresize
XChanges the dimensions of the virtual terminal to explicitly given
Xnumbers.
XIn case of memory shortage, this function may fail irrecoverably,
Xleaving the VT struct in an unusable state (except to
X.IR vtclose ).
X.IP vtautosize
XChanges the dimensions of the virtual terminal to conform to the new
Xwindow size.
XIf possible, the sum of rows and saverows is kept constant.
XThe same limitations as for
X.I vtresize
Xapply.
X.IP vtfind
XGiven a window pointer, returns a pointer to the VT struct containing
Xthat window.
XReturns a nil pointer if no such VT struct exists.
X.IP vtsend
XThis function is defined in the library, but you might want to write
Xyour own version.
XIt is called by the library for cases where the virtual terminal must
Xsend a reply back to the computer system.
X(This happens in response to certain ANSI escape sequences, in
Xparticular ESC-[-6-n or ESC-[-c.)
XYou may want to ignore this output, or actually send it down a serial
Xline if you are implementing a terminal emulator program for a
Xmicro-computer.
XThe library's default version calls
X.I vtansiputs
Xwith the same parameters as passed to
X.I vtsend.
X.IP vtwindow
XReturns a pointer to the window contained in the VT struct.
X.IP vtcwidth
XReturns the width of characters drawn in the VT's window.
X.IP vtcheight
XReturns the height of characters drawn in the VT's window.
X.IP vtsetnlcr
XTurns the
X.I nlcr
Xoption on or off.
XWhen on, every LF character received is translated into a CR plus LF.
XThis is useful if you want to perform C style output to a VT window,
Xwhere lines are terminated by a single LF.
XInitially this option is off.
X.IP vtsetlazy
XTurns the
X.I lazy
Xoption on or off.
XWhen on, actual output to the terminal is delayed until the window's
Xdraw procedure is called; when off, all output is drawn immediately.
XInitially this option is off.
X.SH ANSI ESCAPE SEQUENCES
XThe termcap entries for xterm, vt100, vt100em and versaterm would all
Xwork with the emulated terminal (if you could somehow translate the
Xoutput intended for a Unix terminal into calls to
X.IR vtansiputs ).
XUnrecognized escape sequences and control characters are ignored.
X.PP
X*** List all implemented escape sequences here. ***

X.SH DIAGNOSTICS
X.I Vtopen
Xreturns a nil pointer if it can't allocate all the required memory or if
Xthe call to
X.I wopen
Xit makes fails.
X.br
X.I Vtresize
Xand
X.I vtautosize
Xreturn false (zero) if they can't allocate the extra memory required;
Xin this case the VT struct has been damaged beyond repair.

X.SH BUGS
XIn some versions of STDWIN, the scroll bars won't appear and some other
Xfunctionality won't be available unless the program calls
X.I wgetevent.
X.br
XUnless the application calls
X.I vtautosize
Xat all the right moments, it is quite possible that the window size
Xdoesn't match the size of the virtual terminal.
XWhen the window is too small, STDWIN's automatic scrolling will cause
Xthe text to jump around; when it is too large, portions of the
Xscrolled-away text will remain visible but unreachable by the cursor.
X.br
XThe ANSI terminal implementation is incomplete.
XIt certainly isn't a full-fledged VT100.
X.br
XThe behaviour of the cursor at the right margin is slightly
Xunconventional.
X.br
XBold output only works on the Macintosh, and requires that a font called
X``Bold'' (9 points) be available in the system file. This font can be
Xfound in the resources for (some versions of) VersaTerm(TM).
X.br
XThe package makes the assumption that all characters have the same
Xwidth.
X.br
XThe order of parameters indicating rows and columns is internally
Xconsistent, but reversed with respect to order used for h and v
Xcoordinates in the rest of STDWIN.
X.br
XThe origin of cursor coordinates passed to
X.I vtsetcursor
Xis (0, 0), even though the origin used by ANSI escape sequences is
X(1, 1).
X.br
XThe header file defines functions that aren't really part of the public
Xinterface.
