- * The basic design of the pbproxy code is as follows.
- *
- * When a client selects text, say from an xterm - we only copy it when the
- * X11 Edit->Copy menu item is pressed or the shortcut activated.  In this
- * case we take the PRIMARY selection, and set it as the NSPasteboard data.
- *
- * When an X11 client copies something to the CLIPBOARD, pbproxy greedily grabs
- * the data, sets it as the NSPasteboard data, and finally sets itself as 
- * owner of the CLIPBOARD.
- * 
- * When an X11 window is activated we check to see if the NSPasteboard has
- * changed.  If the NSPasteboard has changed, then we set pbproxy as owner
- * of the PRIMARY and CLIPBOARD and respond to requests for text and images.
- *
- * The behavior is now dynamic since the information above was written.
- * The behavior is now dependent on the pbproxy_prefs below.

+ * The basic design of the pbproxy code is as follows.

+ *

+ * When a client selects text, say from an xterm - we only copy it when the

+ * X11 Edit->Copy menu item is pressed or the shortcut activated.  In this

+ * case we take the PRIMARY selection, and set it as the NSPasteboard data.

+ *

+ * When an X11 client copies something to the CLIPBOARD, pbproxy greedily grabs

+ * the data, sets it as the NSPasteboard data, and finally sets itself as 

+ * owner of the CLIPBOARD.

+ * 

+ * When an X11 window is activated we check to see if the NSPasteboard has

+ * changed.  If the NSPasteboard has changed, then we set pbproxy as owner

+ * of the PRIMARY and CLIPBOARD and respond to requests for text and images.

+ *

+ * The behavior is now dynamic since the information above was written.

+ * The behavior is now dependent on the pbproxy_prefs below.

+ */

+ * 1. handle MULTIPLE - I need to study the ICCCM further, and find a test app.

-.SH NAME
-XWin \- X Server for the Cygwin environment on Microsoft Windows
-
-
-.SH SYNOPSIS
-.B XWin
-[ options ] ...
-
-
-.SH DESCRIPTION
-\fIXWin\fP is an X Server for the X Window System on the Cygwin environment
-running on Microsoft Windows.
-
-
-.SH MODES
-\fIXWin\fP can operate in 3 different modes:
-.br
-* \fISingle Window\fP: This is the default mode.  Each X screen
-appears as a single \fIWindows\fP window and all X windows are contained
-within this window.
-(In X terminology, the \fIWindows\fP window contains the root window for
-the screen)
-.br
-* \fIMulti-Window\fP: In this mode \fIXWin\fP uses its own integrated
-window manager in order to handle the top-level X windows, in such a
-way that they appear as normal \fIWindows\fP windows.
-.br
-* \fIRootless\fP: In this mode the X server works in a window
-containing the whole screen but this root window (traditionally covered with an X hatch
-pattern) is hidden from view, so only top-level X windows are seen.
-
-.SH OPTIONS
-In addition to the normal server options described in the \fIXserver(1)\fP
-manual page, \fIXWin\fP accepts the following command line switches,
-\fIall\fP of which are optional:
-
-.SH OPTIONS CONTROLLING WINDOWING MODE
-Only one of these options may be specified.
-.TP 8
-.B (default)
-Windowed or rooted mode.
-Each X screen appears as a single \fIWindows\fP window and all X windows are
-contained within those windows.
-.TP 8
-.B \-multiwindow
-Each top-level X window appears in its own \fIWindows\fP window.
-Also start the integrated \fIWindows\fP-based window manager.
-.TP 8
-.B \-rootless
-Run the server in rootless mode.
-The X server works on a window covering the whole screen but the root window
-is hidden from view.
-.TP 8
-.B \-mwextwm
-Experimental.
-The mode combines \fB\-rootless\fP mode drawing with native \fIWindows\fP
-window frames managed by the experimental external window manager \fIxwinwm\fP.
-.PP
-\fBNOTE:\fP \fI-multiwindow\fP mode uses its own internal window manager.
-All other modes require an external window manager in order to move, resize, and perform other
-operations on the individual X windows.
-
-.SH OPTIONS FOR SPECIFYING X SCREENS
-An X display may be composed of multiple screens.
-The default behaviour is to create a single screen 0 that is roughly the
-size of useful area of the primary monitor (allowing for any window
-decorations and the task-bar).
-
-Screen specific parameters, such as \fB\-fullscreen\fP, can be applied as a
-default to all screens by placing those screen specific parameters
-before any \fB\-screen\fP parameter.  Screen specific parameters placed after
-the first \fB\-screen\fP parameter will apply only to the immediately
-preceeding \fB\-screen\fP parameter.
-.TP 8
-.B \-[no]multimonitors or \-[no]multiplemonitors
-Create a screen 0 that covers all monitors [the primary monitor] on a system with
-multiple monitors.
-This option is currently enabled by default in \fB\-multiwindow\fP mode.
-.TP 8
-.B "\-screen \fIscreen_number\fP [\fIW\fP \fIH\fP [\fIX\fP \fIY\fP] | [[\fIW\fPx\fIH\fP[+\fIX\fP+\fIY\fP]][@\fIM\fP]] ] "
-Create screen number
-.I screen_number
-and optionally specify it's
-.I height,
-.I width
-and
-.I initial position.
-Additionally a
-.I
-monitor number
-(which count from 1) can be specified to place the screen on,
-at which point, all coordinates become relative to that monitor.
-Screen numbers must be contiguous starting from zero and cannot be duplicated.
-
-Examples:
-
-.I "  -screen 0 @1 ; on 1st monitor using its full resolution (the default)"
-
-.I "  -screen 0 800x600+100+100@2 ; on 2nd monitor offset 100,100 size 800x600"
-
-.I "  -screen 0 1024x768@3        ; on 3rd monitor size 1024x768"
-
-.SH OPTIONS CONTROLLING THE APPEARANCE OF THE X SCREEN WINDOWS
-These parameters only apply to windowed mode screens i.e. not
-in \fB-multiwindow\fP or \fB-rootless\fP mode.
-.TP 8
-.B "\-fullscreen"
-The X server window takes the full screen, covering completely the
-\fIWindows\fP desktop.
-.TP 8
-.B \-nodecoration
-Do not give the Cygwin/X window a \fIWindows\fP window border, title bar,
-etc.
-This parameter is ignored when the \fB\-fullscreen\fP parameter is specified.
-.TP 8
-.B \-scrollbars
-Alternative name for \fB\-resize=scrollbars\fP.
-
-.SH OPTIONS CONTROLLING RESIZE BEHAVIOUR
-.TP 8
-.B \-resize[=none|scrollbars|randr]
-Select the resize mode of an X screen.
-
-.RS
-.IP \fB\-resize=none\fP 8
-(default). The screen is not resizable.
-
-In windowed mode, if the window has decorations, a fixed frame is used.
-
-.IP \fB\-resize=scrollbars\fP 8
-The screen window is resizeable, but the screen is not resizable.
-
-In windowed mode, if the window has decorations, a resizing frame is used.
-Scrollbars are drawn when needed to allow the entire X screen
-to viewed by adjusting them.
-
-This also permits screens bigger than the \fIWindows\fP virtual desktop to be used.
-
-This parameter is ignored in \fB-multiwindow\fP or \fB-rootless\fP mode.
-Alternative name is \fB\-scrollbars\fP.
-
-.IP \fB\-resize=randr\fP 8
-The screen is resizable and the screen window is resizeable.
-
-In windowed mode, if the window has decorations, a resizing frame is used.
-
-Resizing the  \fIWindows\fP window will use the RANDR extension to change
-the size of the X screen.  Likewise, changing the size of
-the X screen using the RANDR extension will cause the size
-of the \fIWindows\fP window containing the X screen to be changed.
-
-In \fB-multiwindow\fP or \fB-rootless\fP mode, if the X screen is
-of the same dimensions as a Windows monitor or the virtual desktop,
-the X server will respond to the WM_DISPLAYCHANGED sent when those
-dimensions change by resizing the X screen.  Changing the size
-of the X screen using the RANDR extension is not permitted.
-
-The maximum dimensions of the screen are the dimensions of the \fIWindows\fP virtual desktop.

-Enables [disables] the integration between the Cygwin/X clipboard and
-\fIWindows\fP clipboard.  The default is enabled.
-.TP 8
-.B "\-emulate3buttons [\fItimeout\fP]"
-Emulate a three button mouse; pressing both buttons within

+.SH NAME

+XWin \- X Server for the Cygwin environment on Microsoft Windows

+

+

+.SH SYNOPSIS

+.B XWin

+[ options ] ...

+

+

+.SH DESCRIPTION

+\fIXWin\fP is an X Server for the X Window System on the Cygwin environment

+running on Microsoft Windows.

+

+

+.SH MODES

+\fIXWin\fP can operate in 3 different modes:

+.br

+* \fISingle Window\fP: This is the default mode.  Each X screen

+appears as a single \fIWindows\fP window and all X windows are contained

+within this window.

+(In X terminology, the \fIWindows\fP window contains the root window for

+the screen)

+.br

+* \fIMulti-Window\fP: In this mode \fIXWin\fP uses its own integrated

+window manager in order to handle the top-level X windows, in such a

+way that they appear as normal \fIWindows\fP windows.

+.br

+* \fIRootless\fP: In this mode the X server works in a window

+containing the whole screen but this root window (traditionally covered with an X hatch

+pattern) is hidden from view, so only top-level X windows are seen.

+

+.SH OPTIONS

+In addition to the normal server options described in the \fIXserver(1)\fP

+manual page, \fIXWin\fP accepts the following command line switches,

+\fIall\fP of which are optional:

+

+.SH OPTIONS CONTROLLING WINDOWING MODE

+Only one of these options may be specified.

+.TP 8

+.B (default)

+Windowed or rooted mode.

+Each X screen appears as a single \fIWindows\fP window and all X windows are

+contained within those windows.

+.TP 8

+.B \-multiwindow

+Each top-level X window appears in its own \fIWindows\fP window.

+Also start the integrated \fIWindows\fP-based window manager.

+.TP 8

+.B \-rootless

+Run the server in rootless mode.

+The X server works on a window covering the whole screen but the root window

+is hidden from view.

+.TP 8

+.B \-mwextwm

+Experimental.

+The mode combines \fB\-rootless\fP mode drawing with native \fIWindows\fP

+window frames managed by the experimental external window manager \fIxwinwm\fP.

+.PP

+\fBNOTE:\fP \fI-multiwindow\fP mode uses its own internal window manager.

+All other modes require an external window manager in order to move, resize, and perform other

+operations on the individual X windows.

+

+.SH OPTIONS FOR SPECIFYING X SCREENS

+An X display may be composed of multiple screens.

+The default behaviour is to create a single screen 0 that is roughly the

+size of useful area of the primary monitor (allowing for any window

+decorations and the task-bar).

+

+Screen specific parameters can be applied as a

+default to all screens by placing those screen specific parameters

+before any \fB\-screen\fP parameter.  Screen specific parameters placed after

+the first \fB\-screen\fP parameter will apply only to the immediately

+preceeding \fB\-screen\fP parameter.

+.TP 8

+.B \-[no]multimonitors or \-[no]multiplemonitors

+Create a screen 0 that covers all monitors [the primary monitor] on a system with

+multiple monitors.

+This option is currently enabled by default in \fB\-multiwindow\fP mode.

+.TP 8

+.B "\-screen \fIscreen_number\fP [\fIW\fP \fIH\fP [\fIX\fP \fIY\fP] | [[\fIW\fPx\fIH\fP[+\fIX\fP+\fIY\fP]][@\fIM\fP]] ] "

+Create screen number

+.I screen_number

+and optionally specify it's

+.I height,

+.I width

+and

+.I initial position.

+Additionally a

+.I

+monitor number

+(which count from 1) can be specified to place the screen on,

+at which point, all coordinates become relative to that monitor.

+Screen numbers must be contiguous starting from zero and cannot be duplicated.

+

+Examples:

+

+.I "  -screen 0 @1 ; on 1st monitor using its full resolution (the default)"

+

+.I "  -screen 0 800x600+100+100@2 ; on 2nd monitor offset 100,100 size 800x600"

+

+.I "  -screen 0 1024x768@3        ; on 3rd monitor size 1024x768"

+

+.SH OPTIONS CONTROLLING THE APPEARANCE OF THE X SCREEN WINDOWS

+These parameters only apply to windowed mode screens i.e. not

+in \fB-multiwindow\fP or \fB-rootless\fP mode.

+.TP 8

+.B "\-fullscreen"

+The X server window takes the full screen, covering completely the

+\fIWindows\fP desktop.

+Currently \fB\-fullscreen\fP may only be applied to one X screen.

+.TP 8

+.B \-nodecoration

+Do not give the Cygwin/X window a \fIWindows\fP window border, title bar,

+etc.

+This parameter is ignored when the \fB\-fullscreen\fP parameter is specified.

+.TP 8

+.B \-scrollbars

+Alternative name for \fB\-resize=scrollbars\fP.

+

+.SH OPTIONS CONTROLLING RESIZE BEHAVIOUR

+.TP 8

+.B \-resize[=none|scrollbars|randr]

+Select the resize mode of an X screen.

+

+.RS

+.IP \fB\-resize=none\fP 8

+(default). The screen is not resizable.

+

+In windowed mode, if the window has decorations, a fixed frame is used.

+

+.IP \fB\-resize=scrollbars\fP 8

+The screen window is resizeable, but the screen is not resizable.

+

+In windowed mode, if the window has decorations, a resizing frame is used.

+Scrollbars are drawn when needed to allow the entire X screen

+to viewed by adjusting them.

+

+This also permits screens bigger than the \fIWindows\fP virtual desktop to be used.

+

+This parameter is ignored in \fB-multiwindow\fP or \fB-rootless\fP mode.

+Alternative name is \fB\-scrollbars\fP.

+

+.IP \fB\-resize=randr\fP 8

+The screen is resizable and the screen window is resizeable.

+

+In windowed mode, if the window has decorations, a resizing frame is used.

+

+Resizing the  \fIWindows\fP window will use the RANDR extension to change

+the size of the X screen.  Likewise, changing the size of

+the X screen using the RANDR extension will cause the size

+of the \fIWindows\fP window containing the X screen to be changed.

+

+In \fB-multiwindow\fP or \fB-rootless\fP mode, if the X screen is

+of the same dimensions as a Windows monitor or the virtual desktop,

+the X server will respond to the WM_DISPLAYCHANGED sent when those

+dimensions change by resizing the X screen.  Changing the size

+of the X screen using the RANDR extension is not permitted.

+

+The maximum dimensions of the screen are the dimensions of the \fIWindows\fP virtual desktop.

+If another instance of \fIXWin\fP with the same display number is found running,

+exit silently and don't display any error message.

+.TP 8

+.B "\-xkblayout \fIlayout\fP"

+.TP 8

+.B "\-xkbmodel \fImodel\fP"

+.TP 8

+.B "\-xkboptions \fIoption\fP"

+.TP 8

+.B "\-xkbrules \fIrule\fP"

+.TP 8

+.B "\-xkbvariant \fIvariant\fp"

+These options configure the xkeyboard extension to load

+a particular keyboard map as the X server starts.  The behavior is similar

+to the \fIsetxkbmap\fP program.  The layout data is located at \fI

+__datadir__/X11/xkb/\fP.  Additional information is found in the

+README files therein and in the man page of \fIsetxkbmap\fP.  For example

+in order to load a German layout for a pc105 keyboard one uses

+the options:

+.br

+.I " \-xkblayout de \-xkbmodel pc105"

+

+Alternatively one may use the \fIsetxkbmap\fP program after \fIXWin\fP is

+running.

+

+The default is to select a configuration matching your current layout as

+reported by \fIWindows\fP, if known, or the default X server configuration

+if no matching keyboard configuration was found.

+

+.SH UNDOCUMENTED OPTIONS

+These options are undocumented.  Do not use them.

+

+.TP 8

+.B \-emulatepseudo

+Create a depth 8 PseudoColor visual when running in depths 15, 16, 24,

+or 32, collectively known as TrueColor depths.

+Color map manipulation is not supported, so the PseudoColor visual will

+not have the correct colors.

+This option is intended to allow applications which only work with a depth 8

+visual to operate in TrueColor modes.

+.TP 8

+.B \-internalwm

+Run the internal window manager.

+

+.SH LOG FILE

+As it runs \fIXWin\fP writes messages indicating the most relevant events

+to  the console

+from which it was called and to a log file that by default is located at \fI

+__logdir__/XWin.0.log\fP.  This file is mainly for debugging purposes.

+

+

+.SH PREFERENCES FILE

+On startup \fIXWin\fP looks for the file \fI$HOME/.XWinrc\fP or, if

+the previous file does not exist, \fI

+__sysconfdir__/X11/system.XWinrc\fP.  \fI.XWinrc\fP allows setting

+preferences for the following:

+.br

+* To include items into the menu associated with the \fIXWin\fP icon

+which is in the \fIWindows\fP system tray.  This functions in all

+modes that have a tray icon.

+.br

+* To include items in the system menu which is associated with the \fIWindows\fP

+window that \fIXWin -multiwindow\fP produces for each top-level X

+window, in both the generic case and for particular programs.

+.br

+* To change the icon that is associated to the \fIWindows\fP window that

+\fIXWin -multiwindow\fP produces for each top-level X-window.

+.br

+* To change the style that is associated to the \fIWindows\fP window that

+\fXWin I-multiwindow\fP produces for each top-level X window.

+.PP

+The format of the \fI.XWinrc\fP file is given in the man page XWinrc(5).

+

+.SH EXAMPLES

+Need some examples

+

+

+.SH "SEE ALSO"

+X(__miscmansuffix__), Xserver(1), xdm(1), xinit(1), XWinrc(__filemansuffix__), setxkbmap(1)

+

+

+.SH BUGS

+.I XWin

+and this man page still have many limitations.

+

+The \fIXWin\fP software is continuously developing; it is therefore possible that

+this man page is not up to date.  It is always prudent to

+look also at the output of \fIXWin -help\fP in order to

+check the options that are operative.
