Removes the hidden “resized-width” and “use-resized-width” properties
from GtkTreeViewColumn and instead uses the “fixed-width” property to
serve the same purpose. “fixed-width”, if set, will now override the
auto-sized width (-1 is now a legal value meaning “not set”).
Additional “cleanups” in this commit:
1. When the user resizes the column the “expand” property is now also
set to FALSE, in order to prevent the column from suddenly jumping to a
different width when the window is resized.
2. The code that translated mouse movement to column sizes has been
simplified:
the change in column width is now calculated directly from the distance
the mouse cursor has traveled. Weird behavior that might have happened
previously if the position of the column changed during resizing, is now
prevented.
3. There was some lengthy logic handling the keyboard shortcuts used to
resize treeview columns, which would call gtk_widget_error_bell() once
the minimum or maximum width was reached. Instead of rewriting these
checks I simply set the “fixed-width” property to what was requested,
relying on the fact that it is already clamped between the minimum and
maximum width during size allocation.
I will greatly surprised if anyone notices the missing error bell.

This commit exposes the get_type() functions and standard
headers for accessible implementations. This makes it possible
to derive from the GTK accessible implementations without
GType magic tricks. This is necessary, because we require the
a11y type hierarchy to be parallel to the widget type hierarchy.
So, if you derive a widget and need to adjust its a11y implementation,
you have to be able to derive its accessible implementation.
This commit probably exposes more than is absolutely necessary,
it also exposes accessibles of widgets that are unlikely candidates
for deriving from.
This way, the a11y code knows if a column was reordered, added or
removed and can do the right things instead of trying to guess and
getting it wrong.
Also, this patch finalizes the changes so that only visible columns
exist to the accessibility interface.

Fixes#640741 - gtk_tree_view_column_get_cell_position() seems to be broken
It is supposed to return the offset within the column, but returned
the offset within the tree, changed by allocation.x of the column's
button (which I don't really unserstand and was clearly not working).
Patches by Benjamin Otte.
The "invalidate last column" hack is removed. It is now of no use since
the entire widget will be redrawn when a single column changes.
I've decided that it is isn't feasible to make cell areas runtime-settable
in the time we have left before 3.0, therefore, I'm going with the
approach to allow init() functions to instantiate the default cell area
and issue a warning if a construct property is ignored.
This is not ideal, but it keeps existing icon view and combo box
subclasses working.

Expander animation has been replaced by implicit animations
from the style context.
Column headers are also properly themed, GtkContainer::get_path_for_child()
is implemented and the treeview resets column buttons style on columns
being reordered.
The default CSS has changed to theme treeviews sensibly.
This function is useful to figure out whether the tree view is "blank"
at a given location. For such locations you might want to popup a
custom popup menu, clear the current selection or start rubber banding.
In the future, we are planning on updating GtkTreeView's user
interactions to take advantage of this new function.
Part of bug 350618.
Check (x, y) is inside background area. If yes, continue processing
and clamp the coordinates into cell area. This way we will properly
handle getting a cell (which is only used for setting the focus cell)
for clicks in the indentation area (in LTR and RTL mode) and clicks
in the focus rectangle area in case focus-line-width is large.
No longer need to detect if we're currently resetting the context since
the context properly now avoids re-triggering the reset by properly
avoiding to notify properties that dont change as a result of the reset.
This fixes autosize columns... result can be viewable by checking
tests/testtreeview and setting the second column to autosize and then
expanding/colapsing some rows.
Now we bookkeep the treeview assigned padding asides from the
requested width stored in the GtkCellAreaContext, this removes
the need for bookkeeping the deepest expanded depth in gtktreeview.c
At allocation time, just remove the padding from the allocated width
of the column and feed the rest to the underlying cell area.
The function has been re-implemented around GtkCellArea. This commits
also brings back the invocation of this function in
gtk_tree_view_button_press(). I shouldn't have removed this.
Now consult gtk_cell_area_context_get_preferred_height().
It can be that height-for-widths requested here were too large
when multiple cells are in play because of the alignments stored
in the context... removing the temporary focus-line-width hack.
Allow feeding treeviewcolumn a custom cell-area (or not a custom one,
but allow sharing the cell-area with say, the combo-box area).
This patch also:
- Fixes signal connections to the area (now they do eventually get
disconnected at dispose time, they are handled regardless if a
treeview is set but execute safely, at least there is only one
connection/disconnection).
- Fixes refcounting on the cell_area (GtkCellArea is GInitiallyUnowned).
- Adds a constructor() in order to build the cell-area if one has
not been provided by the caller before hand at g_object_new()
construct time.
Removed gtk_tree_view_get_real_requested_width_from_column() from
gtktreeview.c in favor of this function in the treeviewcolumn domain
(since this function goes and checks treeviewcolumn internals, settings
and derives the real requested width, seems logical this should be done
by the treeviewcolumn instead).
Now the GtkTreeViewColumn takes care of move/resizing its window and
allocating its button (except for the special case of current drag_column
where the column doesnt actually get reallocated).
Some details:
- button_request was not needed, consult the minimum request of the button
- gtk_tree_view_column_get_button() needed to be public as people can set
tooltips on the button (and libgail accesses the button).
Now consult gtk_cell_area_context_get_preferred_height().
It can be that height-for-widths requested here were too large
when multiple cells are in play because of the alignments stored
in the context... removing the temporary focus-line-width hack.

This fix has evolved in the staging branch since all column members are
on a private structure, but since it causes warnings when closing the
windows of the testcellarea test (because the combo-boxes use a treeviewcolumn)
I thought it nice for now to just manually include the fix.
The fix is just proper bookkeeping of delegate objects at dispose() time.
This is still very much a work in progress, but it renders and more or
less works. I will be fixing up the details in the very near future.
Important: this commit breaks ABI as it modifies the GtkTreeViewColumn
structure in gtktreeviewcolumn.h. This is a sealed structure that needs
to be moved to an internal header file, most likely gtktreeprivate.h.
This mostly goes to keep consistency with the changes to GtkSizeRequest
in the last patch, as GtkCellSizeRequest requires GtkCellRenderer and
GtkCellRenderer implements GtkCellSizeRequest there's no use in keeping
them separate.
This patch renames the functions:
gtk_cell_size_request_get_request_mode()
=> gtk_cell_renderer_get_request_mode()
gtk_cell_size_request_get_width()
=> gtk_cell_renderer_get_preferred_width()
gtk_cell_size_request_get_height()
=> gtk_cell_renderer_get_preferred_height()
gtk_cell_size_request_get_size()
=> gtk_cell_renderer_get_preferred_size()
gtk_cell_size_request_get_width_for_height()
=> gtk_cell_renderer_get_preferred_width_for_height()
gtk_cell_size_request_get_height_for_width()
=> gtk_cell_renderer_get_preferred_height_for_width()
... and moves the corresponding vfuncs to GtkCellRenderer.
The patch also renames the implementations of these functions in cell
renderers to include the word "preferrred".

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.
Fixes: https://bugzilla.gnome.org/show_bug.cgi?id=69872
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.
