X.SH DESCRIPTION
X.I STDWIN
Xis a standard interface available for several window systems.
XThis man page describes the common aspects of applications written using
XSTDWIN when run under MIT's X Window System, Version 11.
X.SH COMMAND LINE OPTIONS
XMost applications (to be precise, those that use the
X.I winitnew
Xcall to initialize STDWIN) will accept all options shown in the
Xsynopsis.
XFor most options there can also be a corresponding
X.I resource
X(option string stored in the X server or in ~/.Xdefaults).
XCommand line options override resources; resources override defaults
Xbuilt in the application; application defaults override library defaults.
XUnless otherwise stated, the resources have the same name as the command
Xline options (all in lower case), prefixed with ``.stdwin''.
XFor example, the full name of the resource corresponding to the
X``\-font'' option is named
X.IR program .stdwin.font.
XSince most options have a standard meaning for most X applications, they
Xare not explained in great length here.
XOptions with a specific meaning for STDWIN are:
X.TP
X.BI \-font " font-name"
XSpecifies the font to be used by default in text drawn by the
Xapplication.
XBoth proportional and fixed-width fonts are acceptable
X(except that some old applications look nicer with a fixed-width font).
XThe library default is to use the X server's default (usually 8x13).
X.TP
X.BI \-menufont " font-name"
XSpecifies the font to be used in menus and dialog boxes.
XThe library default is to use the same font as for normal text.
X.TP
X.BI \-foreground " color-spec, " \-background " color-spec"
XSpecify the colors to be used in the application's part of the window.
XThe defaults are black and white.
X.TP
X.BI \-menuforeground " color-spec, " \-menubackground " color-spec"
XSpecify the colors to be used in the menu bar, the scroll bars,
Xdialog boxes and for the window border (the foreground color).
XBy default the same values are used as for
X.B \-foreground
Xand
X.BR \-background .
X.TP
X.B \-reverse
XReverses the uses of foreground and background colors.
X.TP
X.BI \-debuglevel " number"
XSpecifies the amount of debugging output you want; the higher the
Xnumber, the more output you have to wade through.
XThe library default is wisely 0.
X.TP
X.B \-synchronous
XSpecifies that you want the connection with the X server to be
Xmaintained in synchronous mode (each request immediately sent and a
Xreply waited for).
XThis is sometimes useful while debugging.
XNote that synchronous mode can tremendously reduce drawing efficiency.
XSynchronous mode is not set automatically when the debugging level is
Xnonzero, since some bugs go away when it is turned on!
XThis option has no corresponding resource.
X.SH SCROLL BARS
XAll STDWIN applications have two scroll bars (which may be inactive),
Xone to the left of the window and one at the bottom.
XOperation and interpretation of the scroll bars is intended to be
Xidentical to the scroll bars of applications using the X toolkit
X(e.g., xterm).
XSummarizing:
Xthe left button click scrolls forward, the amount varying with
Xthe position of the click in the bar (for the vertical bar, remember
X``line to top'');
Xthe right button similarly scrolls back (``top to line'');
Xthe middle button moves the beginning of the position indicator
X(the gray block) to the position where the button is pressed.
X.SH MENUS
XAll STDWIN applications display one or more menu titles in a
X``menu bar'' at the top of the window.
XPressing and holding a mouse button in a menu title ``pulls down'' a
Xmenu containing text items.
XSliding the mouse cursor over the text items
Xinverts (highlights) the item over which the cursor is currently;
Xreleasing the mouse button when an item is highlighted causes the
Xcorresponding command th be executed by the application.
XReleasing the mouse button outside the menu selects no item.
XSliding the mouse horizontally over the menu titles pulls down the other
Xmenus; at most one menu will be visible at any time.
X.PP
XOne menu, labeled
X.BR X ,
Xis present in all windows.
XIts only item, named
X.BR Close ,
Xis the standard way to close the window; for single-window applications,
Xselecting this also quits the application.
XThe application is free to refuse closing its window, or to ask
Xconfirmation first, or to do whatever when this item is selected; it is
Xmerely a hint that you would like the window to go away, not a request.
X.PP
XMenu items may be marked (``checked'') with a `*' in the left margin; this
Xan indicator that the function selected by the menu item is currently
X``active''.
XThe check mark can be set and cleared by the application for each menu
Xitem; the use should be apparent from the application's documentation.
XMenu items may be inactive (``disabled''); such items cannot be selected
Xand will not be highlighted.
XDisabled items are currently indicated by a `\-' in the left margin.
X.PP
XMenu items may be selectable via a keyboard shortcut.
XThe existence of a keyboard shortcut is shown in the menu item by the
Xpresence of the string
X.RI ``M- c ''
Xin the right margin, where
X.I c
Xcan be any character.
XThe M stands for ``Meta''.
XHolding a ``Meta'' key (possibly labeled Alt, Command, Compose, Left or
Xsome such name on your keyboard, but definitely not Control or Shift)
Xwhile typing a character, usually a letter, will be
Xequivalent to selecting the corresponding menu item with the mouse.
XShortcuts are defined by the application.
XSome shortcuts are conventional in many applications:
XM-Q for Quit, M-S for Save, M-O for Open.
XAlso M-Z for Undo, M-X for Cut, M-C for Copy and M-V for Paste
X(reminiscent of the Macintosh commands).
XUpper and lower case characters are equivalent, unless the application
Xuses the same letter in lower and upper case as shortcuts for
Xdifferent menu items.
X.\"SH DIALOG BOXES
X.\"SH TEXT EDITING
X.\" selecting, button-2 selecting, double-click, cut/paste, delete, arrows.
X.SH EXAMPLE
XHere are some lines you could put in your resource input file:
X
X *stdwin*font:courier12f
X.br
X dpv*geometry:700x850
X.br
X klok*geometry:-1+1
X
XThis sets the font for all STDWIN applications, the initial size for
X.I dpv
Xand the initial position for
X.I klok.
XNote the use of `*' for separators; extra levels of names may be
Xinserted in the future.
X.SH DIAGNOSTICS
X.I STDWIN
Xcan issue complaints about various error conditions, e.g., font not found;
Xthese are intended to be self-explanatory.
XSome messages indicate STDWIN has found an inconsistency in
Xitself or in the X server.
XThese should be reported to the author if the cause isn't obvious.

X.SH AUTHOR
XGuido van Rossum
X.SH BUGS
XI could be sued by Apple for stealing the ``look and feel'' of some
Xaspects of the Macintosh. :-)
X.br
XThe
X.B \-reverse
Xoption doesn't affect the use of colors in dialog boxes.
X.br
XLike so many other window systems, X11 limits the size of windows to
X64Kx64K.
X.br
XSince a STDWIN document is represented as an X11 window (scrolled inside
Xanother X11 window), applications that create really big windows (~32K
Xpixels wide or high) may crash due to a server bug.
X.br
XWhen an application does no window output for some time after a menu
Xitem has been selected, the menu stays visible in its pulled-down state.
X.br
XThe conventional shortcuts for Undo, Cut and Paste aren't very mnemonic.
X(But Apple never thought that was a problem.)
X.br
XThe standard X-STDWIN command line options are best given before all
Xapplication-specific options.
X.br
XIf you are running an application in the background and have
X.I "stty tostop"
Xturned on, warnings or errors from STDWIN may cause the program to
Xblock.
