=== ~~Custom tree model for journal~~ ===

===foreach/forall===

Using gtk_container_foreach or [http://developer.gnome.org/gtk3/3.4/GtkContainer.html#gtk-container-foreach gtk_container_forall] does expect the callback data to be passed in Python, it does work in a subclassed container due to Carlos [http://git.gnome.org/browse/gtk+/commit/?id=db569cbee7e3842d802c5f1d53e28d0dde98ffeb fix in the GtkCallback annotations].

===gtk_clipboard_set_with_data not introspected===

Line 45:

Line 21:

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

It seems like functions with multiple callbacks are still unsupported in pygi. I opened https://bugzilla.gnome.org/show_bug.cgi?id=682604 but unless someone suggest a way to not break API perhaps we should just add our own sugar_clipboard_set_data using closures for now --dnarvaez

=== gdk_property_change ===

Line 59:

Line 37:

AttributeError: 'gi.repository.Gdk' object has no attribute 'property_change'

</pre>

We have a wrapper for this in sugar-toolkit-gtk3 --dnarvaez

TypeError: Could not caller allocate argument 6 of callable property_get

===Palettes===

* Palettes in Views do popup/popdown in a loop: [http://git.sugarlabs.org/~manuq/sugar-toolkit-gtk3/manuqs-sugar-toolkit-gtk3/commit/f751ec4761934a4d7193c7b4de1ab48fba8e619a fix in sugar-toolkit-gtk3/port]

* FavoritePalette: wrong order of items: [http://git.sugarlabs.org/~manuq/sugar/manuqs-erikos-shell-port/commit/1b1ea09f09dc4001698503d14c5b067636e62471 fix in sugar/port]

* when you switch views always the owner Palette comes up

* Home View: when a Palette is up, the search entry is de-focused

* Palette label: 1) icon has gray background and 2) the positioning is not at the left, 3) there is no separation line below the label

* Journal ListView entry Palette: "AttributeError: 'CellRendererActivityIcon' object has no attribute 'get_display'"

* Frame, friend Palette draws not at the correct position

* Mix Menus and Widgets: Palettes can not mix both Menus and Widgets. Gonzalo has implemented a [http://git.sugarlabs.org/read/mainline/blobs/master/sugarmenuitem.py SugarMenuItem] which can be used instead.

===Icon/EventIcon: badge is not drawn at the correct position===

Filed as [http://bugs.sugarlabs.org/ticket/3835 SL #3835]

===Artwork===

Changes in the theme to adopt to:

* [http://bugs.sugarlabs.org/ticket/3836 Palette Icon: background]

* [http://lists.sugarlabs.org/archive/sugar-devel/2012-August/039359.html GtkLabel: background]

Line 199:

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~~===

===Drag-and-drop in home view, random layout===

Partially done in [http://git.sugarlabs.org/sugar/manuqs-erikos-shell-port/commit/204899e21435d12114747127feee2122e6c3efe3 commit 204899e2]. Pending issue: the activity icon is not being displayed while dragging.

~~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.~~

(sugar-session:13647): Gtk-CRITICAL **: gtk_drag_source_set_icon_pixbuf: assertion `site != NULL' failed

===Other issues===

* ~~home, list view not being displayed~~

* activity launch icon in the frame does not stop fading in and out, like loading

* activities launch ~~screen does not go away~~

* activity icon in the frame does not stop ~~blinking~~

* the corners of the frame have grey color

* 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)

* home, favorites view, random layout, can't drag icons

==Done==

=== Can't call gdk_window_set_user_data() ===

=== Custom tree model for journal ===

Fix from: Manuel Quiñones, Simon Schampijer, Gonzalo Odiard

Custom tree model sample: http://dev.laptop.org/~manuq/shell-port/test_custom_treemodel-gtk3.py

Having trouble reimplementing this. See http://mail.gnome.org/archives/python-hackers-list/2011-December/msg00010.html [https://bugzilla.gnome.org/show_bug.cgi?id=680812 this bug] might be related see 8f31e85db1392eb7222593fc0d05144c2bca06a3 in pygobject.

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

===key grabber===

Fix from: Simon Schampijer

- grab_keys needs to be introspectable, [http://lists.sugarlabs.org/archive/sugar-devel/2012-August/039190.html patch]

- is_modifier does not allow to pass no mask anymore, has to be something like "is_modifier(keycode, mask=Gdk.ModifierType.MOD1_MASK)"

=== Xkl.ConfigRec does not have set_model() method ===

Fix from: Manuel Quiñones, Sergey V. Udaltsov

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

Fix from: Simon Schampijer in commit cd29d065.

=== Port the gstreamer code to pygi ===

Fix from: Daniel Narvaez in commit f74489e6 .

=== Remove resize grips ===

Fix from: Manuel Quiñones

Resize grip has been moved from GtkStatusbar to GtkWindow. See "Resize grip" section of the [http://developer.gnome.org/gtk3/3.1/ch25s02.html GTK+2 > GTK+3 porting guide].

Done in [http://git.sugarlabs.org/sugar/manuqs-erikos-shell-port/commit/3efb87f349f56e4167010ac020ad31521e2533a2 commit 3efb87f3].

=== 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
