+.SH DESCRIPTION
+.PP
+The \fBpanedwindow\fR command creates a new window (given by the
+\fIpathName\fR argument) and makes it into a panedwindow widget.
+Additional options, described above, may be specified on the command
+line or in the option database to configure aspects of the panedwindow
+such as its default background color and relief. The
+\fBpanedwindow\fR command returns the path name of the new window.
+.PP
+A panedwindow widget contains any number of panes, arranged
+horizontally or vertically, according to the value of the
+\fB\-orient\fR option. Each pane contains one widget, and each pair of
+panes is separated by a moveable (via mouse movements) sash. Moving a
+sash causes the widgets on either side of the sash to be resized.
+
+.SH "WIDGET COMMAND"
+.PP
+The \fBpanedwindow\fR command creates a new Tcl command whose name is
+the same as the path name of the panedwindow's window. This command
+may be used to invoke various operations on the widget. It has the
+following general form:
+.CS
+\fIpathName option \fR?\fIarg arg ...\fR?
+.CE
+\fIPathName\fR is the name of the command, which is the same as
+the panedwindow widget's path name. \fIOption\fR and the \fIarg\fRs
+determine the exact behavior of the command. The following
+commands are possible for panedwindow widgets:
+.TP
+\fIpathName \fBadd \fIwindow ?window ...? ?option value ...?\fR
+Add one or more windows to the panedwindow, each in a separate pane.
+The arguments consist of the names of one or more windows
+followed by pairs of arguments that specify how to manage the windows.
+\fIOption\fR may have any of the values accepted by the
+\fBconfigure\fR subcommand.
+.TP
+\fIpathName \fBcget \fIoption\fR
+Returns the current value of the configuration option given by
+\fIoption\fR. \fIOption\fR may have any of the values accepted by the
+\fBpanedwindow\fR command.
+.TP
+\fIpathName \fBconfigure \fI?option? ?value option value ...?\fR
+Query or modify the configuration options of the widget. If no
+\fIoption\fR is specified, returns a list describing all of the
+available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for
+information on the format of this list). If \fIoption\fR is specified
+with no \fIvalue\fR, then the command returns a list describing the
+one named option (this list will be identical to the corresponding
+sublist of the value returned if no \fIoption\fR is specified). If
+one or more \fIoption\-value\fR pairs are specified, then the command
+modifies the given widget option(s) to have the given value(s); in
+this case the command returns an empty string. \fIOption\fR may have
+any of the values accepted by the \fBpanedwindow\fR command.
+.TP
+\fIpathName \fBforget \fIwindow ?window ...?\fR
+Remove the pane containing \fIwindow\fR from the panedwindow. All
+geometry management options for \fIwindow\fR will be forgotten.
+.TP
+\fIpathName \fBidentify \fIx y\fR
+Identify the panedwindow component underneath the point given by
+\fIx\fR and \fIy\fR, in window coordinates. If the point is over a
+sash or a sash handle, the result is a two element list containing the
+index of the sash or handle, and a word indicating whether it is over
+a sash or a handle, such as {0 sash} or {2 handle}. If the point is
+over any other part of the panedwindow, the result is an empty list.
+.TP
+\fIpathName \fBproxy \fI?args?\fR
+This command is used to query and change the position of the sash
+proxy, used for rubberband-style pane resizing. It can take any of
+the following forms:
+.RS
+.TP
+\fIpathName \fBproxy coord\fR
+Return a list containing the x and y coordinates of the most recent
+proxy location.
+.TP
+\fIpathname \fBproxy forget\fR
+Remove the proxy from the display.
+.TP
+\fIpathName \fBproxy place \fIx y\fR
+Place the proxy at the given \fIx\fR and \fIy\fR coordinates.
+.RE
+.TP
+\fIpathName \fBsash \fI?args?\fR
+This command is used to query and change the position of sashes in the
+panedwindow. It can take any of the following forms:
+.RS
+.TP
+\fIpathName \fBsash coord \fIindex\fR
+Return the current x and y coordinate pair for the sash given by
+\fIindex\fR. \fIIndex\fR must be an integer between 0 and 1 less than
+the number of panes in the panedwindow. The coordinates given are
+those of the top left corner of the region containing the sash.
+\fIpathName \fBsash dragto \fIindex x y\fR
+This command computes the difference between the given coordinates and the
+coordinates given to the last \fBsash coord\fR command for the given
+sash. It then moves that sash the computed difference. The return
+value is the empty string.
+.TP
+\fIpathName \fBsash mark \fIindex x y\fR
+Records \fIx\fR and \fIy\fR for the sash given by \fIindex\fR; used in
+conjunction with later dragto commands to move the sash.
+.TP
+\fIpathName \fBsash place \fIindex x y\fR
+Place the sash given by \fIindex\fR at the given coordinates.
+.RE
+.TP
+\fIpathName \fBpanecget \fIwindow option\fR
+Query a management option for \fIwindow\fR. \fIOption\fR may be any
+value allowed by the \fBpaneconfigure\fR subcommand.
+.TP
+\fIpathName \fBpaneconfigure \fIwindow ?option? ?value option value ...?\fR
+Query or modify the management options for \fIwindow\fR. If no
+\fIoption\fR is specified, returns a list describing all of the
+available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for
+information on the format of this list). If \fIoption\fR is specified
+with no \fIvalue\fR, then the command returns a list describing the
+one named option (this list will be identical to the corresponding
+sublist of the value returned if no \fIoption\fR is specified). If
+one or more \fIoption\-value\fR pairs are specified, then the command
+modifies the given widget option(s) to have the given value(s); in
+this case the command returns an empty string. The following options
+are supported:
+.RS
+.TP
+\fB\-after \fIwindow\fR
+Insert the window after the window specified. \fIwindow\fR should be the
+name of a window already managed by \fIpathName\fR.
+.TP
+\fB\-before \fIwindow\fR
+Insert the window before the window specified. \fIwindow\fR should be
+the name of a window already managed by \fIpathName\fR.
+.TP
+\fB\-height \fIsize\fR
+Specify a height for the window. The height will be the outer
+dimension of the window including its border, if any. If \fIsize\fR
+is an empty string, or if \fB\-height\fR is not specified, then the
+height requested internally by the window will be used initially; the
+height may later be adjusted by the movement of sashes in the
+panedwindow. \fISize\fR may be any value accepted by \fBTk_GetPixels\fR.
+.TP
+\fB\-minsize \fIn\fR
+Specifies that the size of the window cannot be made less than
+\fIn\fR. This constraint only affects the size of the widget in the
+paned dimension -- the x dimension for horizontal panedwindows, the y
+dimension for vertical panedwindows. May be any value accepted by
+\fBTk_GetPixels\fR.
+.TP
+\fB\-padx \fIn\fR
+Specifies a non-negative value indicating how much extra space to
+leave on each side of the window in the X-direction. The value may
+have any of the forms accepted by \fBTk_GetPixels\fR.
+.TP
+\fB\-pady \fIn\fR
+Specifies a non-negative value indicating how much extra space to
+leave on each side of the window in the Y-direction. The value may
+have any of the forms accepted by \fBTk_GetPixels\fR.
+.TP
+\fB\-sticky \fIstyle\fR
+If a window's pane is larger than the requested dimensions of the
+window, this option may be used to position (or stretch) the window
+within its pane. \fIStyle\fR is a string that contains zero or more
+of the characters \fBn\fP, \fBs\fP, \fBe\fP or \fBw\fP. The string
+can optionally contains spaces or commas, but they are ignored. Each
+letter refers to a side (north, south, east, or west) that the window
+will "stick" to. If both \fBn\fP and \fBs\fP (or \fBe\fP and \fBw\fP)
+are specified, the window will be stretched to fill the entire height
+(or width) of its cavity.
+.TP
+\fB\-width \fIsize\fR
+Specify a width for the window. The width will be the outer
+dimension of the window including its border, if any. If \fIsize\fR
+is an empty string, or if \fB\-width\fR is not specified, then the
+width requested internally by the window will be used initially; the
+width may later be adjusted by the movement of sashes in the
+panedwindow. \fISize\fR may be any value accepted by \fBTk_GetPixels\fR.
+.RE
+.TP
+\fIpathName \fBpanes\fR
+Returns an ordered list of the widgets managed by \fIpathName\fR.
+
+.SH "RESIZING PANES"
+
+A pane is resized by grabbing the sash (or sash handle if present) and
+dragging with the mouse. This is accomplished via mouse motion
+bindings on the widget. When a sash is moved, the sizes of the panes
+on each side of the sash, and thus the widgets in those panes, are
+adjusted.
+.PP
+When a pane is resized from outside (eg, it is packed to expand and
+fill, and the containing toplevel is resized), space is added to the final
+(rightmost or bottommost) pane in the window.
