Otherwise, we could sometimes fail to update the cursor node when the
right row was deleted.
Also, I'd like to file a formal complaint that this node/tree
differentiation makes writing comparisons too complicated.
https://bugzilla.gnome.org/show_bug.cgi?id=668169
Instead, focus nothing and wait until we get focus before doing so. This
restores previous behaviour but still emits proper cursor-changed
events.
Fixes a bunch of bugs in the filechooser which populates the treeview
asynchronously.
https://bugzilla.gnome.org/show_bug.cgi?id=613728
No more signal handler is needed, therefore the code can also get rid of
tracking the treemodel. And we use a faster approach for iterating the
changed cellrenderers: We just iterate all columns instead of over all
cell accessibles, as that number is likely quite a bit smaller.
There was a corner case where the changed signal was not emitted.
If rows were built like this:
1 (not selected)
+ 2 (selected)
+ 3 (not selected)
And row 1 was removed, no signal would be emitted.
I like it when writing tests actually finds bugs that have been around
since 2003 - introduced by 4a03ea2334
actually. :)
We get certain cases, in particular with SELECTION_MULTIPLE, where we
cannot figure out in advance of real_set_cursor() if the selection will
actually change.
Previously, the cursor would just become invalid, which used to
reselect the first row in the treeview later on (without a
cursor-changed signal). This leads to a crash now with the recent
refactorings.
The patch is longer than I'd like it to be, but the situation is kinda
complicated, because we want to make sure to move the cursor to a good
row. It works like this:
1) From the deleted row, search forward for the first row that is not
going to be deleted and is not a separator.
2) If no such row exists, search backwards for a row that is not a
separator.
3) If no such node exists, clear the cursor.
Previously the code used a GtkTreeRowReference, which was (a) less
performant and more importantly (b) hiding errors.
The errors being hidden were the referenced row becoming invalid or
collapsed, because such rows would not be valid cursor rows and it would
be necesary to select a new row and emit a "cursor-changed" signal.
So if a crash bisects down to this commit, it is very likely that the
cursor has not correctly been updated and the cursor row is invalid.
Previously, when the cursor was a descendant of the collapsed row,
the cursor path was set to the collapsed row, but this was not
communicated via cursor-changed events.
_gtk_tree_view_find_path() was not a name that not really described what
the function does. And I kept forgetting it. Also, it took the tree view
as an argument and that was completely unnecessary.
Turned assertion into silent return.
This assertion is only hit when dragging from an empty tree view. In
this case, gtk_tree_view_begin_drag() is triggered from gtkdnd.c and not
from gtk_tree_view_maybe_begin_dragging_row(). We actually want to
cancel the drag at this point, but that is not possible with the GTK+
API as far as I can see.
The alternative is to not allowing the drag to start. This could be
done by simply unsetting the tree view as drag source when it is empty
and setting it as drag source again when rows are added. I didn't
choose to go with this for now, since this will likely break third party
code.
In gtk_tree_view_state_flags_changed() we were setting the background on
the bin_window without the necessary "view" style class, making the
treeview render with the wrong color in some circumstances (such as when
adding an empty treeview in a window, as spotted by Brian Smith).
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.
.. as a replacement for _gtk_rbtree_node_find_parity(). Instead of 1 or
0, the function now returns the index of node in the complete tree
(counting from the root). And this is of course identical to the row
number.
Track the RBNode/RBTree instead of keeping a TreeRowReference. This is a
whole lot faster and less error-prone.
Also, notify the accessible of removal of rows before actually removing
them, so we have a chance to clean up.
The default (out) transfer mode is "full", but the passed "model" pointer gets
set to gtk_tree_view_get_model() which is "transfer none". This caused Python

This commit introduces a new setting, gtk-visible-focus, backed
by the Gtk/VisibleFocus X setting. Its three values control how
focus rectangles are displayed.
'always' is equivalent to the traditional GTK+ behaviour of always
rendering focus rectangles.
'never' does what it says, and is intended for keyboardless
situations, e.g. tablets.
'automatic' hides focus rectangles initially, until the user
interacts with the keyboard, at which point focus rectangles
become visible.

Now that we are not allocating treeview column buttons anymore
with invisible headers, we can't rely on their allocations for
other things like cell area computations anymore. Use x-offset
and width of the column directly, instead.
Include the child widget path in the returned path now. This allows
customizing the path of the current widgets - like adding flags to child
widgets (and maybe siblings in the future).
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.
We have to redraw if we are below a couple of rows that changed height
in do_validate_rows(). This will still require a redraw for a large
amount of cases, can we do better? You would expect that a redraw of
the tree view is not required when the dy changes with the same delta
as the delta of the height accrued when validating the nodes. This
further optimization will likely require changes to the top_row/dy
synchronization code.
It turns out that the gtk_grab_remove() can trigger a do_prelight()
call, which may end up changing prelight_node, and then the state
gets messed up. Moving the grab removal until after we're done with
button_pressed_node and prlight_node makes expanders work reliably.
One thing that is still not right is that the expander doesn't get
prelight again after the animation is done, if you manage to release
without any additional motion events.
https://bugzilla.gnome.org/show_bug.cgi?id=641039
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.
I have never really liked the updates done to the adjustments in
do_validate_rows() and other validation functions. But it is really
required. I have to come up with a real solution to this one day.
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.
When focus is initially grabbed and there is no focus column, when selecting
the first column for focus, further explicitly focus into the first cell
using gtk_cell_area_focus().
the edge.
When focusing left/right or up/down inside GtkCellArea, now we save what
was the last focused cell and if we hit the side (or top or bottom) of
the view we then restore focus to the last focused cell.
This function did alot of nothing, gtk_cell_area_focus() simply returns whether
the focus stays in the area (column) or not, seems not to cause regressions to
just call it directly instead.
Instead this is now enforced in gtk_tree_view_get_cell_area_height().
There are rows for which a height in between 0 and expander_size is
allowed, for example separator rows.
This argument allows the caller to specify that only an editable
cell should start editing but an activatable cell should not toggle
it's state, this is important for public apis like
gtk_tree_view_set_cursor_on_cell() which are only intended to
programatically bring attention to the editing of a specific
row or cell but not actually change any data.
GtkTreeView & CellAreaScaffold updated for the last minute api change.
This fix is incorrect, treeviews dont rely on the expander size for drawing
separator rows (added XXX comment in line), need to fix this somewhere else
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.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=632539
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.

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.

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!".

2006-12-26 Kristian Rietveld <kris@gtk.org>
Lots of scrolling fixes. Made scrolling work properly in not fully
validated tree views; fixed a bunch of corner cases.
* gtk/gtktreeview.c (validate_visible_area): if a row's dy is past
upper - page_size, we know it is located at the end so the test for
dy + height has been dropped.
In the same case if area_below < 0, we know this is the last node
in the tree view so area_above is page_size - height of this row.
(validate_visible_area): got rid of subtracting new_height -
old_height from area_{below,above}, it didn't make any sense at
all and the full height of the row should be subtracted instead.
(validate_visible_area): when scrolling to a given path, set the
top row directly together with the dy offset, then sync that top_row
to the dy.
(gtk_tree_view_set_top_row): new function to directly set a top_row.
(gtk_tree_view_dy_to_top_row): refactored to use
gtk_tree_view_set_top_row().
(gtk_tree_view_top_row_to_dy): make sure dy >= 0 when done.
(gtk_tree_view_adjustment_changed): only update our dy and
top_row if the adjustment's dy actually changed.
2006-12-03 Kristian Rietveld <kris@gtk.org>
* gtk/gtktreeview.c (validate_visible_area): when not using an
explicit alignment, use the full area of the row (not just dy)
to determine how to implicitly align it. (Fixes#363191, reported
by Federico Mena Quintero).
2006-11-24 Michael Natterer <mitch@imendio.com>
* gtk/gtktreeview.c (gtk_tree_view_move_cursor_up_down): if we

2006-11-16 Michael Natterer <mitch@imendio.com>
Add new infrastructure for notifications of failed keyboard
navigation and navigation with restricted set of keys.
The patch handles configurable beeping, navigating the GUI with
cursor keys only (as in phone environments), and configurable
wrap-around. Fixes bugs #322640, #70986, #318827, #334726, #334742
and #309291.
* gtk/gtksettings.c: added properties gtk-keynav-cursor-only,
gtk-keynav-wrap-around and gtk-error-bell.
* gtk/gtkwidget.[ch]: added new signal "keynav-failed" and public
API to emit it. Added New function gtk_widget_error_bell() which
looks at the gtk-error-bell setting and calls gdk_window_beep()
accordingly.
* gtk/gtk.symbols: add the new widget symbols.
* gtk/gtkcellrendereraccel.c
* gtk/gtkimcontextsimple.c
* gtk/gtkmenu.c
* gtk/gtknotebook.c: use gtk_widget_error_bell() or look at the
gtk-error-bell setting instead of calling gdk_display_beep()

* gtk/gtkiconview.c
* gtk/gtklabel.c

* gtk/gtkentry.c

* gtk/gtkrange.c
* gtk/gtktextview.c: consult gtk_widget_keynav_failed() on failed
cursor navigation and leave the widget if it returns FALSE.
* gtk/gtkmenushell.c
* gtk/gtknotebook.c: only wrap around if gtk-keynav-wrap-around
is TRUE.
* gtk/gtkradiobutton.c: ask gtk_widget_keynav_failed() to decide
whether to to wrap-around, and don't select active items on cursor
navigation if gtk-keynav-cursor-only is TRUE. Should look at
gtk-keynav-wrap-around too, will look into that.
