+Setting a standard Sugar toolbar.

+Adding a custom toolbar and icons.

+ from sugar.activity import activity
+ ...
+ class MyActivity(activity.Activity):
+ ...
+    mytoolbox = gtk.Toolbar()
+    helpbut = ToolButton('help') #Stock help icon
+    helpbut.set_tooltip(_("Get help"))
+    helpbut.connect('clicked', self.help_button_pressed)
+    mytoolbox.insert(helpbut, -1)

+    mytoolbox.show()
+    toolbox = activity.ActivityToolbox(self)
+    toolbox.add_toolbar("mytoolbar",mytoolbox)
+    self.set_toolbox(toolbox)
+    toolbox.show()
+In addition to the standard icons in /usr/share/icons/sugar/scalable/ (eg, "go-next"), you can create additional icons by putting an svg in your activity's icons/ directory.  E.g.,
+ icons/my-icon.svg
+And then use it.
