entry has a command associated with it then the result of that
command is returned as the result of the \fBinvoke\fR widget
command.  Otherwise the result is an empty string.  Note:  invoking
a menu entry does not automatically unpost the menu;  the default
bindings normally take care of this before invoking the \fBinvoke\fR
widget command.
.TP
\fIpathName \fBpost \fIx y\fR ?\fIindex\fR?
.
Arrange for the menu to be displayed on the screen at the root-window
coordinates given by \fIx\fR and \fIy\fR.  If an index is specified
the menu will be located so that the entry with that index is
displayed at the point.  These coordinates are adjusted if necessary to
guarantee that the entire menu is visible on the screen.  This command
normally returns an empty string.  If the \fB\-postcommand\fR option
has been specified, then its value is executed as a Tcl script before
posting the menu and the result of that script is returned as the
result of the \fBpost\fR widget command.  If an error returns while

executing the command, then the error is returned without posting the
menu.
.TP
\fIpathName \fBpostcascade \fIindex\fR
.
Posts the submenu associated with the cascade entry given by
\fIindex\fR, and unposts any previously posted submenu.
If \fIindex\fR does not correspond to a cascade entry,
or if \fIpathName\fR is not posted,

 * We use Apple's Pop-Up Button widget to represent the Tk Menubutton.
 * However, we do not use the NSPopUpButton class for this control.  Instead we
 * render the Pop-Up Button using the HITheme library.  This imposes some
 * constraints on what can be done.  The HITheme renderer allows only specific
 * dimensions for the button.
 *
 * The HITheme library allows drawing a Pop-Up Button with an arbitrary bounds
 * rectangle.  However the button is always drawn as a rounded box which is 22
 * pixels high.  If the bounds rectangle is less than 22 pixels high, the
 * button is drawn at the top of the rectangle and the bottom of the button is
 * clipped away.  So we set a minimum height of 22 pixels for a Menubutton.  If
 * the bounds rectangle is more than 22 pixels high, then the button is drawn
 * centered vertically in the bounds rectangle.
 *
 * The content rectangle of the button is inset by 14 pixels on the left and 28
 * pixels on the right.  The rightmost part of the button contains the blue
 * double-arrow symbol which is 28 pixels wide.
 *
 * To maintain compatibility with code that runs on multiple operating systems,
 * the width and height of the content rectangle includes the borderWidth, the
 * highlightWidth and the padX and padY dimensions of the Menubutton.  However,
 * to be consistent with the standard Apple appearance, the content is always
 * be drawn at the left side of the content rectangle.  All of the excess space
 * appears on the right side of the content, and the anchor property is
 * ignored.  The easiest way to comply with Apple's Human Interface Guidelines
 * would be to set bd = highlightthickness = padx = 0 and to specify an
 * explicit width for the button.  Apple also recommends using the same width
 * for all Pop-Up Buttons in a given window.
