This is a premature patch, it traverses the tree's expanded
rows and fetches the deepest depth every time we allocate a
column. The deepest depth should rather be cached and pushed
when a row expands, then recalculated when the deepest expanded
row collapses.
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).
This is because focus in treeviews can be given to cells that cannot do anything
with activation (for better keynav), so we dissociate the concept of cell
activation and focusing.
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 should be implemented as propery height-for-width by
the treeview-refactor branch. This commit includes a FIXME
comment that scroll adjustments should not be updated from
inside size requests but only after receiving an allocation.
This patch adds the GtkScrollablePolicy type property to GtkScrollable
and implements it in all subclasses. GtkScrolledWindow observes this
property to make a good guess about when to show/hide scrollbars for
height-for-width content.
Most scrollable children do not do height-for-width *yet* but
most certainly will (toolpalette, treeview, iconview, textview
widgets all TODO), for scrollable widgets that do have a minimum
and natural size, it's important for them to observe the state
of this property in order to properly drive the scroll adjustments
according to the desired GtkScrollablePolicy. This patch makes
GtkViewport do this.
Patch also adds tests/testscrolledwindow.c to display the effects
of this property.
The scrollable patch removed set_scroll_adjustments (NULL, NULL) from
gtk_tree_view_init() which ensured the treeview would have adjustments
at all times, this patch adds set_v/hadjustment (NULL) to _init to ensure
the same thing (without it, there are crashes when trying to access the
adjustments notably from set_headers_visible() in gedit).
It is just too annoying to have to implement these properties in
every scrollable. Instead, we now have ::min-content-height/width
in GtkScrolledWindow.
We also add GtkScrollablePolicy to determine how to size the
scrollable content.
The GtkScrollable interface provides "hadjustment" and "vadjustment"
properties that are used by GtkScrolledWindow. It replaces
the ::set_scroll_adjustment signal. The scrollable interface
also has ::min-display-width/height properties that can be
used to control the minimally visible part inside a scrolled window.
The gtkprivate.h header contains GtkWidget-specific private symbols that
are not useful except in a handful of cases. Basically everything
includes gtkprivate.h for the GTK_PARAM_* macros.

The idea is that it is way more common to want to manipulate the
actual list, rather than the headers. Once you Tab into the treeview
(and the list part gets the focus), you can use Shift-Tab to focus
the headers.
This means that some hysteresis is added to the focus chain, but
it makes the treeview a lot more convenient to focus with the keyboard.

Because validate_visible_area() can modify the window size (and thus
the underlying surface), it should not be called from within the draw
method. Given that the presize handler is run with a higher priority
than redraw, and the presize handler will validate the visible area,
there should not be cases wherein the draw method is called and
validate_visible_area() has not been run yet.
However, one such a case was gdk_window_process_updates(), which would
trigger the draw method at some point. We now work around this
by factoring this in a new gtk_tree_view_bin_process_updates() function
that will run the presize handler first if needed.
Note: for other platforms, it might still be the case that the draw
method is called and validate_visible_area() has not been run yet.
(For example the Mac backend calls gdk_window_process_updates() from
the drawRect method, and the redraw-in-idle handling thus works
differently). This does not seem to be a problem now, if
it will be in the future we need to take care of that then.
It doesn't make sense to keep them separate as GtkSizeRequest requires a
GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have
one without the other.
It also makes the code a lot easier because no casts are required when
calling functions.
Also, the names would translate to gtk_widget_get_width() and people
agreed that this would be a too generic name, so a "preferred" was added
to the names.
So this patch moves the functions:
gtk_size_request_get_request_mode() => gtk_widget_get_request_mode()
gtk_size_request_get_width() => gtk_widget_get_preferred_width()
gtk_size_request_get_height() => gtk_widget_get_preferred_height()
gtk_size_request_get_size() => gtk_widget_get_preferred_size()
gtk_size_request_get_width_for_height() =>
gtk_widget_get_preferred_width_for_height()
gtk_size_request_get_height_for_width() =>
gtk_widget_get_preferred_height_for_width()
... and moves the corresponding vfuncs to the GtkWidgetClass.
The patch also renames the implementations of the vfuncs in widgets to
include the word "preferrred".
validate_visible_area() can change the vertical adjustment and thus
trigger window moves/scrolls. This seems to change the surface for
which gtk_tree_view_bin_expose() just created a cairo context. Creating
the cairo context after the call to validate_visible_area() fixes
such crashes.
The keysyms create a lot of potential namespace conflicts for
C, and are especially problematic for introspection, where we take
constants into the namespace, so GDK_Display conflicts with GdkDisplay.
For C application compatiblity, add gdkkeysyms-compat.h which uses
the old names.
Just one user in GTK+ continues to use gdkkeysyms-compat.h, which is
the gtkimcontextsimple.c, since porting that requires porting more
custom Perl code.
Since we have a new mechanism for requesting sizes: GtkSizeRequestIface;
it makes no sense to maintain this cache on the GtkWidget structure...
removing the requisition cache however does not break the old "size-request"
signal which is there for backwards compatability reasons.
In any case widget->requisition should not have been accessed,
gtk_widget_get_child_requisition() would have been the correct way
to consult the cache.
This commit also deprecates the newly added gtk_widget_get_requisition()
API and makes it fallback on gtk_size_request_get_size().
This was a style property to let theme engines 'opt-in' to more
correct behaviour while maintaining compatibility with existing
themes. GTK+ 3 engines are expected to handle the more correct
behaviour.
gtk_window_get_group() never returns NULL; if the window isn't in a group,
a default window group is returned instead. Use gtk_window_has_group() instead.
This fixes some previous commits to use accessors to access GtkWindow.

If a a treeview has frequent periodic additions and removals of
rows, it is possible that a page down keypress moves the cursor
out of the height of the treeview. In some of these cases, we
can be tricked into dereferencing a NULL pointer.

Includes fixing all callers to use the cairo region API instead. This is
usually just replacing the function names, the only difference is
gdk_region_get_rectangles() being replaced by
cairo_region_num_rectangles() and cairo_region_get_rectangle() which
required a bit more work.

The old version wasn't introspectable as it didn't have a length
return parameter. Also, delete gtk_tree_path_get_indices_with_depth,
since it's no longer needed.
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 is exposed by overshooting in a HildonPannableArea. Leaking

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!".
