+.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 \fR?\fIwindow ...\fR? ?\fIoption 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 \fR?\fIoption\fR? ?\fIvalue 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 \fR?\fIwindow ...\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 \fR?\fIargs\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 \fR?\fIargs\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.
+.TP
+\fIpathName \fBsash dragto \fIindex x y\fR
+.
+This command computes the difference between the given coordinates and the
+coordinates given to the last \fBsash mark\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 \fBsash dragto\fR 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 \fR?\fIoption\fR? ?\fIvalue 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\-hide \fIboolean\fR
+.
+Controls the visibility of a pane.  When the \fIboolean\fR is true
+(according to \fBTcl_GetBoolean\fR) the pane will not be visible, but
+it will still be maintained in the list of panes.
+.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 \(em 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\fR, \fBs\fR, \fBe\fR or \fBw\fR.  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
+.QW stick
+to.  If both \fBn\fR and \fBs\fR (or \fBe\fR and \fBw\fR)
+are specified, the window will be stretched to fill the entire height
+(or width) of its cavity.
+.TP
+\fB\-stretch \fIwhen\fR
+.
+Controls how extra space is allocated to each of the panes.
+\fIWhen\fR is one of \fBalways\fR, \fBfirst\fR, \fBlast\fR,
+\fBmiddle\fR, and \fBnever\fR.
+The panedwindow will calculate the required size of all its panes. Any
+remaining (or deficit) space will be distributed to those panes marked
+for stretching. The space will be distributed based on each panes
+current ratio of the whole.  The \fIwhen\fR values have the following
+definition:
+.RS
+.TP
+\fBalways\fR
+.
+This pane will always stretch.
+.TP
+\fBfirst\fR
+.
+Only if this pane is the first pane (left-most or top-most) will it
+stretch.
+.TP
+\fBlast\fR
+.
+Only if this pane is the last pane (right-most or bottom-most) will it
+stretch.  This is the default value.
+.TP
+\fBmiddle\fR
+.
+Only if this pane is not the first or last pane will it stretch.
+.TP
+\fBnever\fR
+.
+This pane will never stretch.
+.RE
+.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"
+.PP
+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 (e.g. 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.
+.PP
+Unlike slave windows managed by e.g. pack or grid, the panes managed by a
+panedwindow do not change width or height to accomodate changes in the
+requested widths or heights of the panes, once these have become mapped.
+Therefore it may be advisable, particularly when creating layouts
+interactively, to not add a pane to the panedwindow widget until after the
+geometry requests of that pane has been finalized (i.e., all components of
+the pane inserted, all options affecting geometry set to their proper
+values, etc.).
