It is bad if the image that is used as a fallback for missing
images goes missing itself, so include it as a resource. This
way, it will always be available.
The rules-hint property has always been a fairly bad application API, as
it set some wrong expectations for the developers; deferring to the
theme makes it impossible to design application reliably, and if this is
a usability setting we should either impose this setting on every theme,
or simply drop it.
Our own default theme does not honour the zebra striping, which makes
this function even more questionable.
In practice, usability studies on zebra striping have demonstrated that
alternating colors on a list it improves readability just as much as
clear ruling between rows, or by visually differentiating the selected
row. Zebra striping improves readability (or, at least, it does not
hinder it) on static displays, like a table on paper or a document; on a
dynamic display, like an application's UI, there are different
strategies that yield similar, if not better, results.

The next call to gtk_list_box_get_selection_mode just expected the
GtkListBoxRow's parent to be a GtkListBox and failed when the row was
added to something other than a GtkListBox.

If an icon theme has a file called "foo-symbolic.symbolic.png" which
was converted from svg using gtk-encode-symbolic-svg we will read
it in an recolor, allowing symbolic icons without using librsvg.

If the same position is requested on a popover, it should at least ensure
the window is realized and raised, even if no resizes are queued on the
content. Otherwise other widgets being mapped might raise the windows over
the popover's if its original position is unchanged.

It turns out that when we were painting the shadows, we painted the them
with the base color once, which contained the alpha, and then blurred it
and used it as a mask for the fill, which has the fill again.
To fix this, always paint the base surface with full alpha. The existing
code applies the blur conditionally sometimes in weird ways, so the code
shuffling fix may not look correct, but be assured it is. If the blur
happens, the new cr we return has the *default* color applied, which is
fully opaque black, which works perfectly against the A8 surface.
The fallback spinner code needs some modification, since it is
intentionally using the alpha to paint the lobes which are "in the past".
Since we shouldn't be hitting this fallback path very often, we use a
temporary group and paint it with paint_with_alpha, even though it is
slow.
Introduce a new debug category "actions" and write some messages from
GtkActionHelper about if we can find the actions or not.
We will probably soon want to add some similar messages to
GtkMenuTrackerItem.

This leads to an assertion failure, because parent window is never registered
in the first place, widget's own GdkWindow is. But that window is unregistered
in a generic fashion by GtkWidget code, so there's nothing for us to do here.
https://bugzilla.gnome.org/show_bug.cgi?id=733766
So far, gtk_window_set_focus just did not work when called on
a hidden window. Change it to record the desired focus widget
for hidden windows, and apply it when the window gets shown.
This is similar to how we tread other window properties that
can't be set before the window is realized, like maximized
or fullscreen.
This is related to

The previous code for computing the clip rectangle forgot to respect
the text-shadow CSS property. This is usually not very visible because
text shadows usually don't extend the ink rectangle by very much.
See attached testcase for an example.
Although there is the "changed" signal, it is more correct to notify the
"text" property too. It can be useful for a small text view, where the
text is saved e.g. to gsettings with a binding to the text property.
The "text" property includes only the text, not child widgets or images,
so the notify signal is sent too many times (also for child widgets and
images), but it's not a big problem.
https://bugzilla.gnome.org/show_bug.cgi?id=624791
Currently, when loading an image from a GResource or file we don't take
the scale factor of the display into consideration, and let
GtkIconHelper scale it accordingly.
While this in general works for non-scalable images, we can take
advantage of the native loader's scaling for e.g. SVG images, and load
them at the right scale factor automatically.
This is achieved by switching to a pixbuf loader instead of using the
native function.
https://bugzilla.gnome.org/show_bug.cgi?id=733416
This allows subclasses to render things below and above the text
in the text view. This allows e.g. GtkSourceView to highlight the
cursor row and to render overlays for colum 80. This used to be done
by rendering before/after chaining up to the parent, but that doesn't
work anymore since the view now renders a background, and due to the
use of the pixel cache.
This reverts commit 1ac13435b7.
We want to instead replace this with special vfunc for drawing
below/above the main text so that gtksourceview can use it.
This was silently broken - the code was just assuming that the
text cell renderer is item no. 6 on the list of all cells. That
doesn't work so well if the cell renderers are set up elsewhere
and get rearranged.
Fix this by keeping an explicit pointer to the the text cell.
For images without a concrete size but with an aspect ratio, we took the
wrong code path.
(I even copied the documentation that said "Otherwise" but didn't put an
else clause there, go me!)
Now that widget paths are allowed to have a state, use that state when
querying style properties. This uses a fast path in gtkcssprovider.c and
that is great.
Header-bar and action-bar buttons used to be bigger then others
now everything is as big as those, maintaining two different sizes
for default widgets depending on the placement is a maintainance
nightmare and having controls the same size is good from a usability
point of view.
The toplevel_window was never set, and the only place where it
was used was causing us to hide tooltips needlessly. So removing
it is a double win.
https://bugzilla.gnome.org/show_bug.cgi?id=733321
Add yet another tab for showing information about a widget that
does not quite fit into any of the other tabs (not a property,
not style information, etc...).
For now, we show the widget state, as well as the default and
focus widget for windows.
GtkArrow is deprecated and is not used internally anymore by the
menu button. Document also the fact that if no direction is specified
then the view-context-menu icon is shown.

People expect to be able to call gtk_widget_show_all on the dialog
to make action widgets visible, as seen e.g. in
https://bugzilla.gnome.org/show_bug.cgi?id=733431
To keep this working, we can't always set no-show-all on the
action_box. Only set it when the action_area is not used and empty.
The accel label in menus was getting a small allocation that
caused its draw code to always omit the accelerator string.
Fix that by setting halign to fill. To keep the menu label
left-aligned, set xalign to 0 to compensate.
Make gtk_widget_path_append_for_widget() add the state flags of the
widget, too.
This enables the ability to select pseudoclasses on all elements in a
selector.
Don't take a state when constructing the CSS matcher. Instead, rely on
the newly introduced state in the widget path.
This way, the state can be queried not only on the first element, but on
all elements of the widget path.
Set the widget path state flags with the state flags of the style
context.
We do not update the state flags but replace the previous one because we
want to be able to have save()/restore() unset state flags.
Make backdrop insensitive state more similar to the focused
windows one, mostly to make dark variant more usable and
focused -> backdrop transition less distracting.
Add left/right/top/bottom style classes according to which edge(s)
of the progressbar the progress is adjacent to. Only for a fraction
of 1.0 will we set more than one edge.
Don't shadow existing variables. Instead of sharing the allocation and
then overwriting the width/height when convenient, declare it in the
block we use it in, as, really, the three different paths are all
extremely different, and there's no sense in sharing the variable.
We can't avoid calling set_titlebar in buildable_add_child, since
GtkBuilder assumes that it can e.g. call grab_default at the end,
which only works if the widget is inside a toplevel at that point.
Instead, drop the titlebar and clean up priv->headerbar in constructed
if we find that we don't want a headerbar.
find_by_log_attrs() can return true only in this case:
return moved && !gtk_text_iter_is_end (arg_iter);
So if the iter moved (i.e. something has been found), but is the end
iter, find_by_log_attrs() returns false.
Now the same checks are made in find_visible_by_log_attrs(). The public
functions using find_visible_by_log_attrs() say in their documentation
that false is returned for the end iter, hence the check with
gtk_text_iter_is_end().
https://bugzilla.gnome.org/show_bug.cgi?id=618852
attrs[len] is the last PangoLogAttr available, at the iter position after the
last character of the line.
For a line in the middle or the start of the buffer, the '\n' is taken
into account by 'len'. For example the is_word_end is generally reached
before the '\n', not after. But for the last line in the buffer, where
there is no trailing '\n', it is important to test until attrs[len].
The bug didn't occur before because find_by_log_attrs() worked directly
on the iter passed as the function argument. But now it is no longer the
case.
https://bugzilla.gnome.org/show_bug.cgi?id=618852
- Return true (found) and false (not found) explicitly.
- Set found_offset only when something has been found.
find_backward_cursor_pos_func() was a bit different, the while loop had
the condition "offset > 0" but the return was "offset >= 0". Probably a
micro-optimization, since offset == 0 is always a cursor position.
Anyway now the code is the same as the other functions.
https://bugzilla.gnome.org/show_bug.cgi?id=618852
Do not work with the iter passed as the function argument. Work with
another iter, and set it back to the function argument only if something
has been found.
This fixes a few unit tests. But there are regressions for a few others.

The Adwaita icon theme ships spinners in a scalable directory
with MaxSize=32 and Scale=1. One way to make them scale up in
hi-dpi would be to add an @2 directory with MaxSize=32 and Scale=2,
but that directory would also be consulted in non hi-dpi situations
and give us an effective spinner max size of 64.
Instead, treat svg icons implicitly as hi-dpi, and scale them
up to MaxSize * 2 when in hi-dpi.
This was causing menus to show up in the wrong position in case the menu
popped up towards the top and/or left.
The change to the requisition was in error; it is the allocated size
of the menu, not the toplevel, and doesn't include the shadow.
https://bugzilla.gnome.org/show_bug.cgi?id=591258
This had originally been added to Adwaita in the gnome-themes-standard
commit 7bf01517bc2 but was lost during 3.13 theme changes, causing bug
591258 to reappear.
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.
It's hard to figure out what the "expected_reply" means except under
close examination -- it's actually talking about whether this was a
reply to a ConfigureRequest or not. The inversion in the check doesn't
help either.
Make the code cleaner by moving it above the freeze/thaw case, and
making the check more explicit and without a confusing variable. If we
haven't sent any ConfigureRequests out, then it must be a gratuitous
ConfigureNotify.
Slapping file:// in front of a path does not guarantee a working
uri (e.g. if you are on windows and the path looks like F:\\...).
Therefore, go back to using g_file_new_for_path if we don't have
to deal with a resource.
The animated scrolling interferes with incremental validation.
As short-term solution, disable scrolling animation during
incremental validation. This is not a proper solution, but
it avoids broken behavior like scrollbars that are not reacting
to clicks. The problem was visible, e.g. in the list view
example in gtk3-demo.

gdk_x11_display_set_window_scale() affects the interpretation of the
Xft/DPI XSETTING - it is substituted inside GDK with the value of
Gdk/UnscaledDPI xsetting. However, this change is not propagated to
GTK+ and from GTK+ back to gdk_screen_set_resolution() until the
main loop is run.
Fix this by handling the screen resolution directly in gdk/x11.
This requires duplication of code between GDK and GTK+ since we still
have to handle DPI in GTK+ in the case that GdkSettings:gtk-xft-dpi
is set by the application.

Conceptually, text handles are boxes, whose content is a 'handle',
so draw background, frame and handle. With this, and the previous
commit, the cursor-handle theming in Adwaita now works as intended.
The text handles reuse the style context from their parent widget,
and just add .cursor-handle. That means that the more specific
entry selectors override the .cursor-handle theming unless we
select for .entry.cursor-handle. We also need to work harder to
keep the .entry styling from drawing decorations around the outlines.
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.
Use gtk_text_iter_set_line_offset (&tmp_iter, 0) instead of
gtk_text_iter_get_line(). The difference should not be big. In the first
case the line doesn't need to be traversed thanks to the offset 0. For
get_line(), the btree must be traversed.
A temporary iter is needed to not break the behavior. But the behavior
is quite strange, the function works directly on the iter passed as an
argument to the function, even if the function returns FALSE (not
found). So maybe a later commit will fix this strange behavior.

find_by_log_attrs() was a recursive function. It is replaced by an
iteration.
The already_moved_initially parameter was TRUE only for the recursive
call, so the paramater is removed.
There is also a small cleanup of the find_visible_by_log_attrs()
(remove trailing spaces, fix indentation).
There is still a part to optimize for a later commit.

This is fallout from the recent dialog changes. We don't set the
headerbar as titlebar early enough anymore, so when the window title
gets set, it does not get passed on to the headerbar. So, re-set it
manually when the titlebar is put in place.
https://bugzilla.gnome.org/show_bug.cgi?id=733099
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.

Move the touchscreen switch to the other debug switches, and
move the hidpi spin to the other graphical controls. Since the
Visual tab is getting large, make it scroll. The General tab
is purely informational again.
Otherwise, the CSS background we draw would be clipped if the ink rect
was smaller than the allocation (a very common thing).
Broken since 37030a7710 where we clipped
to the ink rect.
The overlap was caused by using pack-end for the arrow, which
causes it to be allocated from the other end. Avoid the problem
by using pack-start for both the title and the arrow, and
reordering them according to xalign.
Some of the features we expose can be hardcoded via environment
variables. In that case, don't confuse the user by letting them
change settings that have no effect.
The displacement animation has been replaced by edge gradients, that
have a stronger color the harder overshooting is hit. This makes it
possible to remove the internal overshoot window, which was merely
used to have contents displaced when overshooting to top/left.
Overshooting to bottom/right used to cause queue_resize() to be
called on the scrolled window, this isn't necessary anymore either.
https://bugzilla.gnome.org/show_bug.cgi?id=731297
There was this hack, taken verbatim from GtkCList according to the comment,
that would recursively translate the allocation during scrolling, and set
it on children widgets through the direct gtk_widget_set_allocation() setter.
Since commit 4f89eb05cf, this has caused the wrong clipping areas to children
widgets of a textview. The reasons for this seem lost in time, and the approach
seems indeed wrong for windowed widgets as the repositioning of those windows
couldn't happen.
So replace all of this with just a gtk_widget_size_allocate() call, which does
work ok for the children widgets embedded in the "multiple views" gtk demo, and
ought to work for every other widget.

The reparenting happening on the column header so it gets a movable
window breaks the implicit grab, so this is one situation were we
want a pointer grab, if just to replace it.

Code was expecting view coordinates, not widget ones, as we're
only dealing with horizontal displacements, just adding the
horizontal adjustment value suffices.

This saves some code and lets us reuse the color swatch styling.
Among other things, this fixes a lack of discernible border when
the selected color is very similar to the background.

The recent reshuffling caused an ordering problem where we would
hide the action area before relocating the buttons to the header
bar. But hiding makes the default button loose its defaultness.
Rearrange things so that we move the buttons before hiding the
action area, and thus preserve the default.
If the drag gesture gets a GtkGesture::updated signal, the user
is directly interacting through pointer/touch with the range slider,
animating the adjustment value change in this situation can produce
perceived lag, so set the value immediately when this is happening.
Use the adjustment target value when repositioning the cursor, and remove the
checks that ensured the cursor was made onscreen immediately, as there will
be definitely a delay on animated adjustment changes.
When moving the cursor, compare current adjustment value with the post-animation
target value, in order to avoid false "keynav failed" positives as the animation
hasn't started yet, so dx/dy are still 0 at that time.
