OLPC XO Opera browser as Sugar activity

[Stevens]

Hi Bert, all,

I changed the script (OperaActivity.py) posted on the wiki (http:// 
wiki.laptop.org/go/Opera).

This is the old script:

> import logging
> from sugar.activity import activity
>
> import sys, os
> import gtk
>
> class OperaActivity(activity.Activity):
>
>     def __init__(self,handle):
>         activity.Activity.__init__(self,handle)
>
>         self.set_title('Opera Activity')
>
> 	os.system('opera -notrayicon &')


The above script resulted in the 'blank screen' activity. I added a  
personaldir switch, shown below:

import logging
from sugar.activity import activity

import sys, os
import gtk

class OperaActivity(activity.Activity):

     def __init__(self,handle):
         activity.Activity.__init__(self,handle)

         self.set_title('Opera Activity')

	os.system('opera -notrayicon -personaldir $SUGAR_ACTIVITY_ROOT/data &')

(The only change is in the last line: added personaldir command line  
switch.)

This resulted in progress. Now, in addition to the blank screen  
activity, it starts Opera.

However, this may not have been the right thing to do, or I may need  
to make some additional changes as there is still a bug: two glyphs  
show up in the activity circle, one the Opera glyph which when  
clicked on goes to a blank screen, and the other (a gray circle)  
which when clicked on goes to Opera. (Before I made the change to the  
script just the blank screen activity started.)

Is the change I made correct for this case? And, is there some other  
change I should make to eliminate the 'blank screen' being started?

-Peter
