In the early 2.14.x releases, GtkAdjustment was changed to enforce
that values are restricted to the range [lower, upper - page_size].
This has always been the documented behaviour, and the recommended
practice is to set page_size to 0 when using adjustments for simple
scalar values, like in a slider or spin button.
Due to the large number of applications that are affected by this
change, the behaviour has been reverted to the old behaviour in
2.14.3, with an explicit warning that this change will be
reintroduced in 2.90.
This reverts commit e6373738fc.

This is exposed by overshooting in a HildonPannableArea. Leaking
a GtkTreeRowReference also means leaking the whole model, since
the GtkTreeModel reference count is increased for each row
reference.
Fixes bug #607770 - Leak in GtkTreeView with HildonPannableArea
Deprecate widget flag macros GTK_WIDGET_STATE, GTK_WIDGET_SAVED_STATE,
GTK_WIDGET_FLAGS, GTK_WIDGET_TOPLEVEL, GTK_WIDGET_NO_WINDOW and
GTK_WIDGET_COMPOSITE_CHILD.
Also deprecate the type macros GTK_WIDGET_TYPE, GTK_OBJECT_TYPE_NAME and
GTK_OBJECT_TYPE which have become redundant.
Instances of GTK_WIDGET_TOPLEVEL are replaced with gtk_widget_is_toplevel,
GTK_WIDGET_TYPE is replaced with G_OBJECT_TYPE, GTK_WIDGET_COMPOSITE_CHILD
is replaced with use of the "composite-child" property and uses of
GTK_WIDGET_NO_WINDOW are adjusted to use gtk_widget_get_has_window.
Uses of GTK_WIDGET_SAVED_STATE and GTK_WIDGET_FLAGS inside GtkWidget are
changed to direct flag usage.
Documentation is updated to refer to gtk_widget_set_has_window and
gtk_widget_get_has_window.
Gail and tests are updated as well.

Initialize event_last_[xy] to out of range coordinates and also update
these values in enter and leave notify. Fix up calls to
update_prelight() from size allocate. Unconditionally doing these calls
caused problems with hover selection. Now we only do this call when
the "width before the expander column" has changed. (Which might be
awkward, but it is the best heuristic I could come up with so far).
Commit again after revert.
Store (x, y) of last motion event. From
gtk_tree_view_adjustment_changed(), call prelight_or_select() so that
the prelight is recalculated. We do the same from
gtk_tree_view_size_allocate() for the case that clicking on an expander
shows new rows that resize the column(s) left of the expander. This
means that the expander is moved horizontally, in such a case the
prelight also has to be reconsidered.
The Gtk-custom.c file in gir-repository contained a number of
introspection annotations. Merge those into the GTK source files.
Some documentation was moved from the tmpl/ files to accomodate
the addition of annotations.
Rework double click handling in GtkTreeView. We cannot blindly use
the 2BUTTON_PRESS and 3BUTTON_PRESS events. In case a user does two
fast double clicks, we receive a 3BUTTON_PRESS and BUTTON_PRESS. We
cannot easily deduce two double clicks from this.
We have removed the bookkeeping using row references of the last paths
clicked. Instead we monitor event time, (x, y) coordinates and compare
against double-click-time and double-click-distance ourselves.

Commit 3f306a4042 made it possible for
gtk_tree_view_top_row_to_dy() to be called recursively. (In a different
way than was already guarded for). This caused a single test case in
the scrolling test suite to fail. We now also guard for recursive calls at
the beginning of gtk_tree_view_top_row_to_dy().
This was removed long ago by the patch in bug 101235. On a hindsight,
all other scrollable widgets are processing exposes at this point, which
completely makes sense to me, so I am putting it back.
Such paths (eg. a child node that is collapsed) should be ignored. This
is fixed by checking the return value of _gtk_tree_view_find_node(),
which returns a partial return value (the parent node) when it returns
TRUE. Also added a unit test.
Reorder drawing in gtk_tree_view_bin_expose() so that the tree lines are
drawn after the cells have been drawn. This is because cell-background
is handled in the cell renderer, so the tree lines need to be drawn
after this.
Contrary to what was believed before, do_validate_rows() does need to
queue a normal resize (including a redraw) when it has to. The redraw
is required because of the size of the tree has changed because new
row(s) have been validated.
In validate_visible_area() it was assumed that gtk_tree_path_prev()
would always return the correct path of the preceding node. This is
obviously not true. The if-clause has been removed so that we now
always use _gtk_tree_view_find_path() to get the path from the tree,
node.
gtk_tree_view_enter_notify() now "ignores" the synthesized crossing
events. The synthesized crossing events always have (0, 0) as
coordinates, which messes things up. This patch does not fix all issues,
at least it makes the behavior much more reasonable again. Watch bug
555109 for further discussion on the issue.
Adapt gtk_tree_view_get_path_at_pos() and
gtk_tree_view_get_drag_dest_row() to just return FALSE when bin_window
is NULL and not hit a warning. Makes this case consistent with the tree
view not having a model. Documentation has been updated to clarify
this, unit test has been added.
Fixes bug 539377, based on a patch by Bjorn Lindqvist.
Instead of failing with warning on !tree_view->priv->tree, return
silently when tree_view->priv->model is NULL. Clarified in the
documentation that for invalid paths (and every path is invalid when no
model is set), the function will fail silently although the current
cursor will be unset.
Fixes bugs 498010 and 546005.
gtk_tree_view_discover_dirty_iter() and gtk_tree_view_discover_iter()
have been in the tree forever, but unused since 1.3.8 or so. I guess we
no longer need them, so removed them. Fixes a compiler warning as well.
Previously, do_validate_rows() validated 300 rows per iteration. While
this is usually not problematic, as the typical tree view contains less
than 100 rows. Tree views with a lot of columns or complex cell
renderers could take inacceptably long, like:
- Epiphany's location bar entry completion has multiline and marked up
text in every cell. Validating a single row took ~1.5ms here.
- In the list view in Nautilus, When enabling all columns, validating a
single row would take ~3ms.
With 300 rows per iteration, that made those examples take 500ms/1s in a
signle main loop callback, and this obviously caused responsiveness
problems.
Now the code uses a timer and limits the time for validating rows to
30ms. This can cause less lines to be invalidated per call, so the
function might be called more often, but generally results in more
responsive applications.
GtkFileChooserDefault actually implements a binding signal for
Backspace, to make it go to the parent directory. However,
GtkTreeView was eating our Backspace, and thus the file chooser was
not getting a chance to execute its binding signal.
GtkTreeView implements a Backspace binding itself, which it uses to
move to the parent node of the current cursor node. However, the
binding handler would return TRUE even if there was no parent to the
current node. Now the binding handler only returns TRUE if it
actually changed the cursor.
Additionally, gtk_tree_view_key_press() sees if no bindings handled a
key press; in that case, it re-sends the key press to the treeview's
search entry. However, sending a Backspace to an empty entry makes
the entry beep. Thus, we add a flag that gets set from GtkTreeView's
Backspace binding handler, to tell gtk_tree_view_key_press() when it
should *not* re-emit the key press on the search entry. Sort of,
"yeah, I didn't handle this key press, but I don't want you to send it
to the search entry, either!".
