Previously we were assuming that only list box rows could occur
as focus children of a list box, and would crash if that wasn't
the case. This commit handles this case, and integrates focusable
headers into directional keynav and the focus chain.
The typical case of using separators as headers is not affected
by this change.

Don't use gtk_widget_show_all() on row widgets because that would
unconditionally show all of its children. This might be unwanted in case
the row implementation wants to keep some of its children hidden.
This commit changes it to use show() instead of show_all() and relies on
the row widget to control the visibility of its children itself as
appropriate.

We are trying to scroll the header in view together with the
focus row. The way this is implemented works fine when scrolling
up, but falls short when scrolling down. Fix this by making sure
that both the row and the header bar visible.
We automatically pick up an adjustment from our parent
scrollable, but we failed to update it when it changes.
This is happening in the places sidebar, and it was causing
the focus-tracking to fail there, letting the focus move
out of view. With this change, the focus remains visible.
gtk_css_node_set_after/before() are now called
gtk_css_node_insert_after/before().
This brings them in line with other similar APIs (ie GtkListStore). And
it allows easier usage of the API (see changes to gtkbox.c).
So objects connected by g_signal_connect_after actually get
the signal.
This was causing an issue in the dnd highlight, since there
a cairo rectangle is draw using g_signal_connect_after on the draw
signal.
This applies the proper CSS child ordering semantics using GtkCssNode to
GtkListBox. You can now use :first-child, :last-child, :nth-child(), and
:last-nth-child() selectors.
For example, this allows styling row separators using CSS while ignoring
the separator on the last row.
GtkListBoxRow {
border-bottom: 1px solid @borders;
}
GtkListBoxRow:last-child {
border-bottom: none;
}
When the sort ordering of the listbox changes, we also update the CSS
node ordering.
As it is, GtkListBox model binding will work nicely as long as your
create_widget_func returns a floating reference on the newly-created
widget.
If you try to return a full reference (as any higher-level language
would do) then you will leak that reference.
Fix that up by converting any floating references into full references
and then unconditionally releasing the full reference after adding to
the box.

Although gtk_list_box_row_grab_focus() is not a public function
it can be easily called by gtk_widget_grab_focus() with a row argument
which has been removed from the list box and has box == NULL.

gtk_list_box_bind_model() binds a GListModel to a GtkListBox.
This is a first step towards having GListModel support in Gtk. It's not
useful for large models, because GtkListBox always creates all widgets
for all rows.
Rows are not necessarily selected via select_row_internal(), add
the missing signal emissions there. Also the signal should be emitted
when removing the selection altogether.
https://bugzilla.gnome.org/show_bug.cgi?id=729809
We now apply the .button style class to rows that are either
activatable or selectable. Selectable rows only get the .button
if the listbox allows selection. This implies that we need to
update row styles when the selection mode changes, or when the
row gets added to a listbox.
Having an explicit property for this will make it easier
to have a hover style only for rows which are activatable
or selectable.
Rows are selectable by default, to preserve compatibility.
The listbox code relies on the container focus adjustment handling
to scroll the cursor row on screen. But GtkContainer has no idea
about row headers, so ensure that we scroll the header on screen too.
This will let us theme activatable rows differently.
We also avoid emitting the ::row-activated signal for
rows that are not activatable. For compatibility reasons,
rows are activatable by default.

This commit adds API for dealing with multi-selection. It is identical
to the flow box API for this purpose. The implementation is still limited
to single-selection, and will be updated in subsequent commits.
The button press/release handlers did invariably return FALSE, even
though it shouldn't if a row was found on the event coordinates. Also,
use GDK_EVENT_* defines for the return values.
The 'direction' parameter to gtk_widget_keynav_failed() is based on
gtk_list_box_move_cursor()'s 'count' parameter. However if the passed
in movement is GTK_MOVEMENT_DISPLAY_LINES, 'count' is modified by
the keynav handling and will always be 0. To avoid messing up the
'direction' parameter, use a local variable for keynav handling and
leave 'count' untouched.

keyboard navigation didn't support activation since we moved
the keynav to the child row widgets. We fix this by adding a
activate signal handler for the row and setting
widget_class->activate_signal to it.

... to make it possible to insert rows in the middle of the list without having
to fiddle with the sort functions. One of the first users is going to be Glade.

We already take care to not track headers when the listbox is hidden,
because that can be very expensive during creation, so we might as
well skip reseparate() too. The only time we don't want to skip it
is when we're about to show the list.
This was added from https://bugzilla.gnome.org/show_bug.cgi?id=691979
where it was wanted in order to get a "all children filtered" kind
of row. However, the solution is not really generic enough, because
filtering can happen for other reasons than a full refilter (i.e. due
to a row change), and the partial fix you can get by counting children
after refilter can be achieved by manually doing it whenever you manually
called refilter anyway.
Its possible we should have some better solution for the "empty state"
though.
Now that we automatically set up the focus_vadjustment we only
need the adjustment to handle the page-up/down scroll length correctly.
We use parent_set to automatically pick up the adjustment from a
scrollable (i.e. viewport) parent which makes add_to_scrolled useless, so
it can be removed.
Unhighlight rows if they are removed.
Drop the automatic drag motion based auto-scrolling. This is not really
right, as it e.g. hardcodes auto-scroll regions and assumes we're the only
widget inside the scrolled container. Its also imho in the wrong place,
autoscrolling if any should be done on the scrolled-window or viewport.
All the removed code is implementable outside Gtk+ though.
