+=== Palettes can't include menu and widgets at the same time ===
+We can use anything like this:
+<pre>
+class SugarMenuItem(gtk.EventBox):
+    __gsignals__ = {
+        'clicked': (gobject.SIGNAL_RUN_FIRST, None, [])
+    }
+    def __init__(self, icon_name, label_text):
+        gtk.EventBox.__init__(self)
+        self._sensitive = True
+        vbox = gtk.VBox()
+        hbox = gtk.HBox()
+        vbox.set_border_width(style.DEFAULT_PADDING)
+        self.icon = Icon()
+        self.icon.props.icon_name = icon_name
+        hbox.pack_start(self.icon, expand=False, fill=False,
+                padding=style.DEFAULT_PADDING)
+        align = gtk.Alignment(xalign=0.0, yalign=0.5, xscale=0.0, yscale=0.0)
+        text = '<span foreground="%s">' % style.COLOR_WHITE.get_html() + \
+                    label_text + '</span>'
+        self.label = gtk.Label()
+        self.label.set_use_markup(True)
+        self.label.set_markup(text)
+        align.add(self.label)
+        hbox.pack_start(align, expand=True, fill=True,
+                padding=style.DEFAULT_PADDING)
+        vbox.pack_start(hbox, expand=False, fill=False,
+                padding=style.DEFAULT_PADDING)
+        self.add(vbox)
+        self.id_bt_release_cb = self.connect('button-release-event',
+                self.__button_release_cb)
+        self.id_enter_notify_cb = self.connect('enter-notify-event',
+                self.__enter_notify_cb)
+        self.id_leave_notify_cb = self.connect('leave-notify-event',
+                self.__leave_notify_cb)
+        self.modify_bg(gtk.STATE_NORMAL, style.COLOR_BLACK.get_gdk_color())
+        self.show_all()
+        self.set_above_child(True)
+    def __button_release_cb(self, widget, event):
+        self.emit('clicked')
+    def __enter_notify_cb(self, widget, event):
+        self.modify_bg(gtk.STATE_NORMAL,
+                style.COLOR_BUTTON_GREY.get_gdk_color())
+    def __leave_notify_cb(self, widget, event):
+        self.modify_bg(gtk.STATE_NORMAL, style.COLOR_BLACK.get_gdk_color())
+    def set_icon(self, icon_name):
+        self.icon.props.icon_name = icon_name
+    def set_label(self, label_text):
+        text = '<span foreground="%s">' % style.COLOR_WHITE.get_html() + \
+                    label_text + '</span>'
+        self.label.set_markup(text)
+    def set_sensitive(self, sensitive):
+        if self._sensitive == sensitive:
+            return
+        self._sensitive = sensitive
+        if sensitive:
+            self.handler_unblock(self.id_bt_release_cb)
+            self.handler_unblock(self.id_enter_notify_cb)
+            self.handler_unblock(self.id_leave_notify_cb)
+        else:
+            self.handler_block(self.id_bt_release_cb)
+            self.handler_block(self.id_enter_notify_cb)
+            self.handler_block(self.id_leave_notify_cb)
+            self.modify_bg(gtk.STATE_NORMAL, style.COLOR_BLACK.get_gdk_color())
+</pre>
+And add them to a vbox:
+<pre>
+        # TODO: private!!!
+        self._content.set_border_width(0)
+        self._play_pause_button = SugarMenuItem('player_play',
+                _('Say selected text'))
+        self._play_pause_button.connect('clicked', self.__play_clicked_cb)
+        vbox_menu.add(self._play_pause_button)
+</pre>
+To do the SegurMenuItem take all the width in the palette, we need set the border_width in _content to zero,
+but that is a private member. Then we need to look if we add a method to set the it,
+or change the api to make the first container (where is the menu today) useful for other type of widgets.
