-Valid values for this option are \fBbottom\fR, \fBcenter\fR,
-\fBleft\fR, \fBnone\fR, \fBright\fR and \fBtop\fR. The default value
-is \fBnone\fR, meaning that the menubutton will display either an image or
-text, depending on the values of the \fB\-image\fR and \fB\-bitmap\fR
-options.
-.VS
.OP \-direction direction Height
Specifies where the menu is going to be popup up. \fBabove\fR tries to
pop the menu above the menubutton. \fBbelow\fR tries to pop the menu
below the menubutton. \fBleft\fR tries to pop the menu to the left of
the menubutton. \fBright\fR tries to pop the menu to the right of the
menu button. \fBflush\fR pops the menu directly over the menubutton.
-.VE
+In the case of \fBabove\fR or \fBbelow\fR, the direction will be
+reversed if the menu would show offscreen.
.OP \-height height Height
Specifies a desired height for the menubutton.
If an image or bitmap is being displayed in the menubutton then the value is in
screen units (i.e. any of the forms acceptable to \fBTk_GetPixels\fR);
for text it is in lines of text.

.SH INTRODUCTION
.PP
The \fBmenubutton\fR command creates a new window (given by the
and is associated with a menu widget.
If text is displayed, it must all be in a single font, but it
can occupy multiple lines on the screen (if it contains newlines
-or if wrapping occurs because of the \fBwrapLength\fR option) and
+or if wrapping occurs because of the \fB\-wraplength\fR option) and
one of the characters may optionally be underlined using the
-\fBunderline\fR option. In normal usage, pressing
+\fB\-underline\fR option. In normal usage, pressing
mouse button 1 over the menubutton causes the associated menu to
be posted just underneath the menubutton. If the mouse is moved over
the menu before releasing the mouse button, the button release
causes the underlying menu entry to be invoked. When the button
is released, the menu is unposted.
.PP
-Menubuttons are typically organized into groups called menu bars
+Menubuttons are used to construct a \fBtk_optionMenu\fR, which is the
+preferred mechanism for allowing a user to select one item from a list
+on Mac OS X.
+.PP
+Menubuttons were also typically organized into groups called menu bars
that allow scanning:
if the mouse button is pressed over one menubutton (causing it
to post its menu) and the mouse is moved over another menubutton
in the same menu bar without releasing the mouse button, then the
menu of the first menubutton is unposted and the menu of the
new menubutton is posted instead.
+\fIThis use is deprecated\fR in favor of setting a \fBmenu\fR directly as a
+menubar; see the \fBtoplevel\fR's \fB\-menu\fR option for how to do that.
.PP
There are several interactions between menubuttons and menus; see
the \fBmenu\fR manual entry for information on various menu configurations,
such as pulldown menus and option menus.
-
.SH "WIDGET COMMAND"
.PP
The \fBmenubutton\fR command creates a new Tcl command whose
determine the exact behavior of the command. The following
commands are possible for menubutton widgets:
.TP
-\fIpathName \fBcget\fR \fIoption\fR
+\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 \fBmenubutton\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
this case the command returns an empty string.
\fIOption\fR may have any of the values accepted by the \fBmenubutton\fR
command.
-
.SH "DEFAULT BINDINGS"
.PP
Tk automatically creates class bindings for menubuttons that give them
focus to allow keyboard traversal of the menu and its submenus.
See the \fBmenu\fR manual entry for details on these bindings.
.IP [7]
-If the \fBunderline\fR option has been specified for a menubutton
+If the \fB\-underline\fR option has been specified for a menubutton
then keyboard traversal may be used to post the menubutton:
Alt+\fIx\fR, where \fIx\fR is the underlined character (or its
lower-case or upper-case equivalent), may be typed in any window
under the menubutton's toplevel to post the menubutton.
.IP [8]
The F10 key may be typed in any window to post the first menubutton
-under its toplevel window that isn't disabled.
+under its toplevel window that is not disabled.
.IP [9]
If a menubutton has the input focus, the space and return keys
post the menubutton.
.PP
The behavior of menubuttons can be changed by defining new bindings for
individual widgets or by redefining the class bindings.
