Manuq started the port of the shell branching the hippo removal. The main issues were identified by Daniel Drake some months ago and fortunately most of them are fixed at this point.

Daniel Narvaez set up a sugar-build branch to make the port. To test:

git clone git://git.sugarlabs.org/~dnarvaez/sugar-build/manuqs-shell-port.git

That is sugar-build with this sugar components branched:

http://git.sugarlabs.org/~manuq/sugar/manuqs-erikos-shell-port  
http://git.sugarlabs.org/~manuq/sugar-toolkit-gtk3/manuqs-sugar-toolkit-gtk3

Custom tree model for journal

Having trouble reimplementing this. See http://mail.gnome.org/archives/python-hackers-list/2011-December/msg00010.html this bug might be related see 8f31e85db1392eb7222593fc0d05144c2bca06a3 in pygobject.

Gonzalo provided an initial patch, and Manuq worked over it.

Current patch: http://dev.laptop.org/~manuq/journal_gtk3-2.patch

Previous patch that includes the switch to new toolbars: http://dev.laptop.org/~manuq/journal_gtk3.patch .

Calling Gio.VolumeMonitor.get() crashes Sugar:

Xkl.ConfigRec does not have set_model() method

This should be called in the setup keyboard at the startup. setup_keyboard_cb in sugar/bin/sugar-session . Reported in pygobject as: https://bugzilla.gnome.org/show_bug.cgi?id=681566

Seems that libxklavier needs a setter. Reported to libxklavier as https://bugzilla.freedesktop.org/show_bug.cgi?id=53547

gtk_clipboard_set_with_data not introspected

In the annotations it is marked as non-introspectable.

http://www.daa.com.au/pipermail/pygtk/2011-July/019940.html

- check with pygobject devs if the above statement is still the case

gdk_property_change

Is marked as non-introspectable in the annotations.

>>> from gi.repository import Gdk
>>> Gdk.property_change
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

gdk_property_get

The gdk_property_get annotations mark it as introspectable.

Not working:

def _property_get_trapped(window, prop, prop_type):
    Gdk.error_trap_push()

    prop_atom = Gdk.Atom.intern(prop, False)
    type_atom = Gdk.Atom.intern(prop_type, False)

    logging.warning("get prop %s %s %s", window, prop_atom, type_atom)
    prop_info = Gdk.property_get(window, prop_atom, type_atom, 0, 9999, False)
TypeError: Could not caller allocate argument 6 of callable property_get

Port hardcoded styles to the CSS stylesheet

For example in sugar/extensions/cpsection/network/view.py we have things like:

        label_server = gtk.Label(_('Server:'))
        label_server.set_alignment(1, 0.5)
        label_server.modify_fg(gtk.STATE_NORMAL,
                               style.COLOR_SELECTION_GREY.get_gdk_color())

Palettes can't include menu and widgets at the same time

We can use anything like this:


class SugarMenuItem(gtk.EventBox):

    __gsignals__ = {
        'clicked': (gobject.SIGNAL_RUN_FIRST, None, [])
    }

    def __init__(self, icon_name, label_text):
        gtk.EventBox.__init__(self)
        self._sensitive = True
        vbox = gtk.VBox()
        hbox = gtk.HBox()
        vbox.set_border_width(style.DEFAULT_PADDING)
        self.icon = Icon()
        self.icon.props.icon_name = icon_name
        hbox.pack_start(self.icon, expand=False, fill=False,
                padding=style.DEFAULT_PADDING)
        align = gtk.Alignment(xalign=0.0, yalign=0.5, xscale=0.0, yscale=0.0)
        text = '<span foreground="%s">' % style.COLOR_WHITE.get_html() + \
                    label_text + '</span>'
        self.label = gtk.Label()
        self.label.set_use_markup(True)
        self.label.set_markup(text)
        align.add(self.label)
        hbox.pack_start(align, expand=True, fill=True,
                padding=style.DEFAULT_PADDING)
        vbox.pack_start(hbox, expand=False, fill=False,
                padding=style.DEFAULT_PADDING)
        self.add(vbox)
        self.id_bt_release_cb = self.connect('button-release-event',
                self.__button_release_cb)
        self.id_enter_notify_cb = self.connect('enter-notify-event',
                self.__enter_notify_cb)
        self.id_leave_notify_cb = self.connect('leave-notify-event',
                self.__leave_notify_cb)
        self.modify_bg(gtk.STATE_NORMAL, style.COLOR_BLACK.get_gdk_color())
        self.show_all()
        self.set_above_child(True)

    def __button_release_cb(self, widget, event):
        self.emit('clicked')

    def __enter_notify_cb(self, widget, event):
        self.modify_bg(gtk.STATE_NORMAL,
                style.COLOR_BUTTON_GREY.get_gdk_color())

    def __leave_notify_cb(self, widget, event):
        self.modify_bg(gtk.STATE_NORMAL, style.COLOR_BLACK.get_gdk_color())

    def set_icon(self, icon_name):
        self.icon.props.icon_name = icon_name

    def set_label(self, label_text):
        text = '<span foreground="%s">' % style.COLOR_WHITE.get_html() + \
                    label_text + '</span>'
        self.label.set_markup(text)

    def set_sensitive(self, sensitive):
        if self._sensitive == sensitive:
            return

        self._sensitive = sensitive
        if sensitive:
            self.handler_unblock(self.id_bt_release_cb)
            self.handler_unblock(self.id_enter_notify_cb)
            self.handler_unblock(self.id_leave_notify_cb)
        else:
            self.handler_block(self.id_bt_release_cb)
            self.handler_block(self.id_enter_notify_cb)
            self.handler_block(self.id_leave_notify_cb)
            self.modify_bg(gtk.STATE_NORMAL, style.COLOR_BLACK.get_gdk_color())

And add them to a vbox:


        # TODO: private!!!
        self._content.set_border_width(0)
 
        self._play_pause_button = SugarMenuItem('player_play',
                _('Say selected text'))
        self._play_pause_button.connect('clicked', self.__play_clicked_cb)
        vbox_menu.add(self._play_pause_button)

To do the SegurMenuItem take all the width in the palette, we need set the border_width in _content to zero, but that is a private member. Then we need to look if we add a method to set the it, or change the api to make the first container (where is the menu today) useful for other type of widgets.

In Manuq branch, palettes are blinking when mouse is over the icon.

A handful of NMClient issues

See http://mail.gnome.org/archives/python-hackers-list/2011-August/msg00003.html and the other posts in the thread. Some problems resolved, some probably still pending.

Owner icon allocation issue

The owner icon is displayed above the center in home and neighborhood views. If we don't take into account the container offset it looks ok, (test removing this line: y -= allocation.y) but then is bad aligned if an alert is displayed in the view.

Drag-and-drop in home view, random layout

Partially done in commit 204899e2. Pending issue: the activity icon is not being displayed while dragging.

Other issues

  • activity launch icon in the frame does not stop fading in and out, like loading
  • widgets like icons and texts have grey background instead of black (toolbar-grey) - this is because of a change in gtk (seen in Browse too)

Done

Remove resize grips

Fix from: Manuel Quiñones

Resize grip has been moved from GtkStatusbar to GtkWindow. See "Resize grip" section of the GTK+2 > GTK+3 porting guide.

Done in commit 3efb87f3.

Custom Icon cell renderer

Fix from: Manuel Quiñones

sugar3.graphics.icon.CellRendererIcon is based on pygtks GenericCellRenderer - needs to be ported

gconf_client_get_list not introspectable

Workaround from: Daniel Drake

The annotations mark it as non-introspectale.

opened an upstream bug: https://bugzilla.gnome.org/show_bug.cgi?id=681433

similar boxed types fix: https://bugzilla.gnome.org/show_bug.cgi?id=613247

The keyboard is not set up yet because of this as is being called in setup_keyboard_cb in sugar/bin/sugar-session .

Needs:

Custom TreeModelSort for home list view

Fix from: Simon Feltman, Manuel Quiñones

Can't inherit GtkTreeModelSort and pass a model to the parent constructor. Filed as: https://bugzilla.gnome.org/show_bug.cgi?id=681477

Working testcase for pygtk: http://dev.laptop.org/~manuq/test_listmodel2_gtk2.py

Testcase that shows the issue in PyGi: http://dev.laptop.org/~manuq/test_listmodel2_gtk3.py

Needs:

  • can be made to work by passing keyword arguments e.g. "Gtk.TreeModelSort.__init__(self, model=self._model_filter)"

can't call gdk_window_set_user_data()

In the latest implementation we don't use set_user_data anymore AFAIK. http://mail.gnome.org/archives/python-hackers-list/2011-September/msg00006.html

do_forall not working in pygobject

Fix from: Tomeu Vizoso, John Palmieri, Carlos Garnacho

Needs:

cant call gdkwindow.raise()

Fix from: Martin Pitt

Needs:

can not listen to signals in subclassed subclasses

Fix from: Carlos Garnacho

ActivityIcon.do_draw never called, see http://bugs.sugarlabs.org/ticket/3386

Needs:

set_data/get_data not available anymore

Fix in toolkit-gtk3 from: Simon Schampijer

More background info in: https://bugzilla.gnome.org/show_bug.cgi?id=641944

Needs:

libxklavier

Fix from: Manuel Quiñones

This is how Anaconda is using libxklavier in Python (found when coming across this bug, Colin enabled introspection for libxklavier).

You have to use Xkl.Engine.get_instance(display) instead of the constructor. Manuq made sure the API we use is there. This testcase was useful.
