Hey Michael,

Did you try applying Sayamindu's patch from the previous email (and did you
see the associated screenshot)?

I'm surprised it hasn't been cleaned up and pushed by the Sugar dev team by
now.

Re: anonymous gray activity circles

2009-01-04 Thread Mikus Grinbergs
> Here's a short code tour for your enjoyment.

Thank you very much, Michael.  This is very helpful.


Would it be possible for you (or someone else) to similarly 
enumerate the conditions under which 'anonymous gray activity 
circles' are made to disappear ?

I don't have difficulty with gray circles while activities are 
running (I can figure out which circle is which session) -- but it 
leaves an untidy impression when the session itself goes away, but 
the gray circle does not.  [In fact, I once saw so many leftover 
gray circles that the top bar of Frame showed "arrowheads" for the 
viewer to scroll back and forth within the "ActivitiesTray".]

Maybe if I can understand *why* gray circles might persist, I might 
be able to think of a way to force leftover useless ones to go away. 
[I would guess a gray circle left behind by a  session 
could only be gotten rid of by restarting Sugar.]

Here's a short code tour for your enjoyment. I'll start by tracing
backwards from what we know:

1. Clone the sugar source code:

   git clone git://git.sugarlabs.org/sugar/mainline.git sugar

2. We know that things including gray circles appear in the top part of
the frame. What causes this?

   cd sugar
   find . -name '*frame*'
   # Inspiration!
   cd src/jarabe/frame

3. Start reading files here looking for info about how the frame is
constructed. 

   Ah hah! We find out from src/jarabe/frame/frame.py that the frame
   consists of four panels.

   
http://git.sugarlabs.org/projects/sugar/repos/mainline/blobs/master/src/jarabe/frame/frame.py#line117

   What goes in the top panel? Read _create_top_panel():

   
http://git.sugarlabs.org/projects/sugar/repos/mainline/blobs/master/src/jarabe/frame/frame.py#line177

   Bingo! An ActivitiesTray()!

4. Go find ActivitiesTray():

   First, search for "ActivitiesTray". Find the import line at

   
http://git.sugarlabs.org/projects/sugar/repos/mainline/blobs/master/src/jarabe/frame/frame.py#line29

   Next, go read src/jarabe/frame/activitiestray.py looking for the
   definition of ActivitiesTray()

   
http://git.sugarlabs.org/projects/sugar/repos/mainline/blobs/master/src/jarabe/frame/activitiestray.py#line299

5. Figure out what message causes the tray to add icons.

   Doesn't that __activity_added_cb() callback look suspicious? 
   
   Let's figure out what causes self._home_model to generate
   'activity-added' signals.

6. Track down self._home_model.

   Ah! In ActivitiesTray.__init__, we set it equal to shell.get_model().

   Where does the variable "shell" come from? From here:

   
http://git.sugarlabs.org/projects/sugar/repos/mainline/blobs/master/src/jarabe/frame/activitiestray.py#line39

7. Track down 'get_model' in src/jarabe/model/shell.py

   
http://git.sugarlabs.org/projects/sugar/repos/mainline/blobs/master/src/jarabe/model/shell.py#line573

   So what's a ShellModel?

8. Look more carefully at ShellModel.

   We find the definition of the 'activity-added' signal here:
   
   
http://git.sugarlabs.org/projects/sugar/repos/mainline/blobs/master/src/jarabe/model/shell.py#line282

   alongside several other tasty-sounding signals.

   ...

   Oooh, look at the __init__ method:

   
http://git.sugarlabs.org/projects/sugar/repos/mainline/blobs/master/src/jarabe/model/shell.py#line310

   Doesn't that "window-open" signal sound interesting?

9. Review.

   We've pretty much figured out the chain of events that results in the
   appearance of a new button on the frame's top panel's activities tray.

   Moreover, while we still don't really know why the buttons sometimes
   display gray circles vs activity icons or how to remove a button, we
   can be fairly sure that the answers lie close by, e.g.

   (where the gray circles come from:)
   
http://git.sugarlabs.org/projects/sugar/repos/mainline/blobs/master/src/jarabe/frame/activitiestray.py#line67
 

   and back in jarabe.model.shell.ShellModel, which seems to be driving
   the show w.r.t. to the display and removal of items in the
   ActivitiesTray.

10. Forward.

   The questions which remain include:

 a) What things are driving the ShellModel? Are they doing so
 correctly?

hint: nope. read 
  
http://git.sugarlabs.org/projects/sugar/repos/mainline/blobs/master/src/jarabe/model/shell.py#line434
  
http://standards.freedesktop.org/startup-notification-spec/startup-notification-latest.txt

(also, please help me get the ideas in the patches at the top of
  http://dev.laptop.org/git/users/mstone/sugar and 
  http://dev.laptop.org/git/users/mstone/sugar-toolkit
merged which, while they won't solve your problem, may still be
generally useful.)

 b) What icon data should we be feeding into those buttons? Where
 does it come from?

hint: read 
  http://standards.freedesktop.org/wm-spec/latest/
  http://standards.freedesktop.org/wm-spec/latest/ar01s05.html#id2569669

Vaguely related, I had did some work to avoid the gray circles: you
can see the result at:
http://dev.laptop.org/~sayamindu/standard_icons.png

The relevant patch (it needs some work) is at http://dev.laptop.org/ticket/8661

I'll resume work on it when I have some more time - in the meanwhile,
if anyone is enthusiastic enough, please feel free to take that patch
forward.

Thanks,

Thanks for the reply.  Unfortunately, I'm
not a python programmer so searching through
the source entails quite a learning curve...
Perhaps someone with real knowledge of the

Re: anonymous gray activity circles

Yes, but these are un-sugarized programs
and they still generate gray circles.
Doesn't that imply that window creation

acted upon?

Re: anonymous gray activity circles

2009-01-03 Thread Tony Anderson
Compare:

http://laguna.fmedic.unam.mx/~daniel/pygtutorial/pygtutorial/getting-started.html

which creates a top-level window and

http://wiki.laptop.org/go/PyGTK/Hello_World_Tutorial

as a sugar activity.

The first has the line:

window = GtkWindow(WINDOW_TOPLEVEL) # create a top level window

while the latter has:

# Create the main container
self._main_view = gtk.VBox()

Sugar has already created the top-level window with an empty VBox, so 
the activity only needs to pack that VBox with widgets.

Essentially to eliminate the grey circle, you need to modify the 
initialization code (with the two tutorials as a guide).

Re: anonymous gray activity circles

2009-01-03 Thread Chris Marshall
Two specific questions come to mind:

(1) How does Sugar know that a new top level
 window has been instantiated?  Is there a
 hook from the X server or what?

(2) What sort of cleanup is needed to make
 the anonymous gray circle go away?  Do
 you have to notify Sugar or what?

I'm trying to implement some code that uses
OpenGL via the Mesa library on the XO.  As
the code re-generates display graphics, the
gray circles keep accumulating.  I would
like to keep the number of circles equal
to the number of actual top level windows
and not the total number used across the
session.

Thanks,
Chris

os767 and Firefox-6 activity
start firefox
click on a file link to download
exit firefox after
left a gray circle

(Actually, it almost always leaves behind one
or more circles but I have not done exhaustive
testing to determine how many or under what
conditions.  It would be easier to start from
an understanding of how the circle gets there
to begin with (what is being used to trigger
the circle's appearance)...

I happen to have "sugarized" Sonata.  [There appears to be some 
"uncertainty" in the launching of the mpd daemon that performs the 
actual playback.]  I do not mind the Sonata gray circle while the 
"Activity" is running.  On Joyride-2610, if I exit from Sonata by 
hovering on its gray circle in Frame, and clicking 'Stop' in the 
palette Frame shows me, the "Activity" seems to quit without leaving 
the gray circle behind.

But [probably depending on the state of the mpd daemon] if I exit 
from Sonata by clicking on the octagonal 'Stop sign' in the top bar, 
sometimes an anonymous gray activity circle gets left in Frame.

It would be nice if there were a way for an user to remove "dead" 
circles from Frame.

Anyone who ever tried to run a non-sugarized application has seen this.

re: anonymous gray activity circles

2008-12-30 Thread Greg Smith
Hi Chris,

Unless someone else has seen this, I think we need more detail on how to
reproduce it.

Can you write down the steps it takes to get a "gray activity circle"? 
Include the version of XO software you are running: 
http://wiki.laptop.org/go/What_release_am_I_running%3F

It may be that you are double clicking to start an activity. That can 
cause a second activity instance to try and start then fail and leave an 
icon in the frame. That's the only thing that comes to mind without more 
detail.

Thanks,

Greg S

Is there a way to prevent the
anonymous gray activity circles
in the frame?  Some X apps
seem to accumulate circles with
no way i have been able to
determine to remove "dead" ones.
I tried to google the list but was
not able to generate useful links.
