The [[Development_Team/Almanac|Sugar Almanac]] also has lots of code snippets.

WINDOW_WIDTH, WINDOW_HEIGHT = 700, 500

Setting a standard Sugar toolbar.
from sugar.activity import activity
...
class MyActivity(activity.Activity):
...
toolbox = activity.ActivityToolbox(self)
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. Eg,
Adding a custom toolbar and icons.
from sugar.graphics.toolbutton import ToolButton
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)
helpbut.show()
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
icons/my-icon.svg
And then use it.
=== Other notes ===
mybut = ToolButton('my-icon')# without extension

This snippet shows how to get [http://lists.laptop.org/pipermail/devel/2008-March/011799.html a path to an activity's writable directories] (i.e. the SUGAR_ACTIVITY_ROOT environment variable; see also [[Activity_DBus_API#Security | the activity DBus API]]):
class WebActivity(activity.Activity):
def __init__(self, handle):
activity.Activity.__init__(self, handle)
temp_path = os.path.join(self.get_activity_root(), 'instance')
