=== Sugar toolbar version ===
Sugar toolbars changed in Sucrose v0.86. You can detect which version you are running by checking for an ImportError:
try: # 0.86 toolbar widgets
from sugar.bundle.activitybundle import ActivityBundle
from sugar.activity.widgets import ActivityToolbarButton
from sugar.activity.widgets import StopButton
from sugar.graphics.toolbarbox import ToolbarBox
from sugar.graphics.toolbarbox import ToolbarButton
_new_sugar_system = True
except ImportError:
_new_sugar_system = False
Use the flag to determine whether to create old-style or new toolbars:
if _new_sugar_system:
# Use 0.86+ toolbar design
toolbar_box = ToolbarBox()
...
else:
# Use pre-0.86 toolbar design
self.toolbox = activity.ActivityToolbox(self)
...
You can share callbacks between versions, but take care to make sure you are using the proper context:
# 0.86+
fullscreen_button.connect('clicked', self._do_fullscreen_cb)
or
# pre-0.86
self.viewToolbar = ViewToolbar(self)
class ViewToolbar(gtk.Toolbar):
def __init__(self, pc):
self.activity = pc
self.activity.fullscreen_button.connect('clicked', self.activity._do_fullscreen_cb)
