Features/GTK3/Shell
Daniel Drake started an effort to port the shell to the GTK3 sugar-toolkit. These are the biggest issues identified so far:
Custom tree model for journal
Having trouble reimplementing this. See http://mail.gnome.org/archives/python-hackers-list/2011-December/msg00010.html
Custom Icon cell renderer
sugar3.graphics.icon.CellRendererIcon is based on pygtks GenericCellRenderer - needs to be ported
do_forall not working in pygobject
Update, this bugs are fixed and do_forall is working in the shell port branch.
Needs:
- https://bugzilla.gnome.org/show_bug.cgi?id=663052 gobject-introspection was merged 2012-07-13
- https://bugzilla.gnome.org/show_bug.cgi?id=644926 pygobject missing header file in patch. was merged 2012-03-27
gtk_clipboard_set_with_data not introspected
cant call gdkwindow.raise()
Update: this bug is fixed in pygobject, see https://bugzilla.gnome.org/show_bug.cgi?id=676746 .
raise is reserved word in Python. Workaround: getattr(win, 'raise')()
See http://mail.gnome.org/archives/python-hackers-list/2011-December/msg00011.html
xklavier
python-xklavier is based on pygtk codegen, we can probably just drop the link to pygtk, but failing that, we will need introspection bindings.
gdk_property_get
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
ActivityIcon.do_draw never called
see http://mail.gnome.org/archives/python-hackers-list/2011-December/msg00013.html filed as https://bugzilla.gnome.org/show_bug.cgi?id=672864
set_data/get_data not available anymore
https://bugzilla.gnome.org/show_bug.cgi?id=641944, we can use python attributes here
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())
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.
Can't call gdk_window_set_user_data()

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.
