Re: anonymous gray activity circles
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 defunct session could only be gotten rid of by restarting Sugar.] mikus ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: anonymous gray activity circles
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. -Wade On Sun, Jan 4, 2009 at 5:55 PM, Michael Stone mich...@laptop.org wrote: On Sat, Jan 03, 2009 at 02:23:41PM -0500, Chris Marshall wrote: 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? 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 and start asking questions.

Re: anonymous gray activity circles
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.

Re: anonymous gray activity circles
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
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 internals can suggest an approach or more specifics about where to look. --Chris Tony Anderson wrote: Hi, I didn't notice about your use of OpenGL. My remarks referred to GTK. However, what I think is happening is that the application is creating a new window. On non-sugar systems, they appear as separate windows. However, in the case of Sugar, I think it is expected that application will work in a single window. The result is in some sense 'undefined'. You will need to look at the source code and find where the source code recreates a new window and change it to repaint the current window (canvas?). Keep in mind I am reporting as an activity developer, not from a real knowledge of the internals.

Re: anonymous gray activity circles
Some X apps seem to accumulate circles with no way I have been able to determine to remove dead ones. 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. mikus ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
