This is used for example in the source tab of gtk4-demo.
It broke because GtkScrollbar no longer is a GtkRange,
but rather has one. So we need to forward the signal.
It was selecting paned separator, which means any separator at any level
of descent within a paned, including the toplevel container in GEdit.
We need to be more specific and only select the relevant separator that
is the direct child of the paned. This is what Adwaita does.

Nulling priv->button in _unset_tree_view() is asymmetrical: we create
it via init(), not _set_tree_view(), so we shouldn’t null in the latter.
Worse, doing so manifests in criticals + a SEGV easily with basic use of
testtreecolumns, removing the TVC from a TV then trying to add it to one
Finally, the wrong null-out meant dispose() failed to unref the button,
so it leaked.

This patch makes that work using 1 of 2 options:
1. Add all missing enums to the switch statement
or
2. Cast the switch argument to a uint to avoid having to do that (mostly
for GdkEventType).
I even found a bug while doing that: clearing a GtkImage with a surface
did not notify thae surface property.
The reason for enabling this flag even though it is tedious at times is
that it is very useful when adding values to an enum, because it makes
GTK immediately warn about all the switch statements where this enum is
relevant.
And I expect changes to enums to be frequent during the GTK4 development
cycle.
GtkCellArea uses event coordinates (thus in treeview relative
coordinates), but calculations used to happen in bin window coords.
We can just offset the cell area by the bin window, fixes cell
renderer activation and edition.
If the column is not clickable, it may make some sense to stop
event propagation here for button events. However motion events
should be left alone.
Fixes treeview column resize pointer cursors, since that's
implemented up the bubbling phase in the treeview.
The operations rely there on bin window relative coordinates, but we
are receiving GtkTreeView relative coordinates there. Fixes clicking
on treeview expanders, which was offset by visible headers.
-Wint-conversion is important because it checks casts from ints to
pointers.
-Wdiscarded-qualifiers is important to catch cases where we don't
strings when we should.
The border and icon highlight are useful feedback that was defeated by
CSS precedence. It worked for .titlebuttons due to their implementation,
but the same was not true for custom .flat buttons. This makes it so.
https://bugzilla.gnome.org/show_bug.cgi?id=788580
When the window was backdropped, they suddenly regained their border.
This was clearly not intentional or of any practical use to anyone.
Shuffle around some selectors so that the backdrop ones do not override
the flat ones and make the borders magically reappear when backdropped.
Note that, whereas standard titlebuttons get the border on :hover, other
.flat buttons in the headerbar do not. That should probably be fixed too

They were hard-coded to a transparent black, but that is our bg colour
in HC Inverse, so windows stacked on top of each other or a dark
background blended together into a mush.
Fix this by making the $_wm_border* colours relative to the fg colour,
so that HighContrastInverse gets borders that are transparentised white.

A missing decoration selector meant that we got a solid black background
behind the rounded corners of the dialog.
Copy the equivalent code from Adwaita, including nicely rounding the
focus outline too (& sorry, but this needs more newlines to be readable)
There were various problems, like only selecting on .tooltip and not the
widget node tooltip, not being specific enough for tooltip.csd, etc. So,
specific theming was absent, and default popup window styles got applied
This commit copies in the better working tooltip CSS from Adwaita, but
applies a couple of changes to make it work better in the HC themes:
• Reduce the transparency of the tooltip, so we achieve higher contrast
• Drop the black text-shadow, as it is not useful on this more black bg
Note: we may then need to re-add some of this to the .tooltip class. But
it is unclear what needs done there. While Adwaita is not doing it, we
are better not to confuse by keeping it in HC only; we should try to be
as close as possible, to make it easier for HC to keep up with Adwaita.

We need
.window-classes decoration

n_attach_points is the result of g_strv_length(): the index at which the
string vector ends in NULL. So by definition, when i == n_attach_points,
string[i] == NULL, and there is no need to check for the latter. The
fact that we did appears to confuse static analysers, as the dereference
and index check were inverted from what would normally be safe. We could
reverse them, but we may as well just remove the unnecessary NULL check.

This gives consistent behavior with e.g. Qt, Mozilla's suites and
LibreOffice (with non-truly native backends like "gen" and "gtk",
but unlike "gtk2" and "gtk3" ones that probably use true GTK menus).
This behavior is expected by at least some accessibility users, and
it seems good to behave like other common applications and toolkits
in this area. There should be no issue in doing so either for current
users, as it only enters the submenu instead of not doing anything.

ComboBox and TreeMenu warned in the doc for :row-span-column that the
value must not exceed :wrap-width, but :wrap-width does not interact
with the number of rows; it’s the :column-span-column that’s relevant.
Also: Warn that spans must be > 0 for rows too, and that column spans <=
:wrap-width are also not useful for items at menu column positions > 0.
Finally, refer to items having spans, not values, as we were already
talking about values in the model (and rows in the menu).
Instead of creating one GPtrArray per GtkSnapshotState and saving nodes
in there, create one GPtrArray per snapshot and assign a
start_node_index to every GtkSnapshotState as well as a n_nodes variable
so every state knows which nodes belong to it.
It's not a GtkCssGadget anymore, it doesn't have any properties or
signals either and it's not public. Further, its lifetime is very clear
the way it's being used inside GTK+.
This showed up in profiles in certain scenarios, so export a
_get_n_shadows getter instead and let callers provide a sufficiently
large allocated array of GskShadows, which we can use with
g_alloc/g_newa.
The GtkFlowBoxCreateWidgetFunc type lacked GObject Introspection
annotations for its arguments. This made gtk_flow_box_bind_model()
unusable from Python as the callback function would be passed useless
values.
The annotations that I've added match those of the similar callback
type GtkListBoxCreateWidgetFunc.

Those should be interpreted by widget-local gestures, not guessed at a
high level with no notions of the specific context. Users will want
GtkGestureMultiPress to replace these events.
Those worked similarly to those in GtkFlowBox, but would additionally
handle "active" state for child rows. Simplify this to just enabling/
disabling active state on gesture press/release, we don't get the
nice state updates when hovering around with a mouse button pressed,
but the rationale from flowbox applies here, and makes a nice cleanup.
They just maintain priv->in_button and widget state up-to-date, this
basically matters during user interaction, and is already maintained
in the gesture ::update handler. This seems to be sufficient.
Those basically controlled priv->active_child_active, which would
1) trigger a redraw when the pointer enters/leaves it, and 2) ensure
that press/release happen on the same child for it to be activated.
The former is not necessary, and the latter can be simplified by
just checking again the child on the coordinates given by the
::release gesture handler. This makes all enter/leave/motion_notify
event handlers unneeded.
All kinetic scrolling initial velocity calculations are now
taken from the scroll controller. The handling of timeouts
to snap back when overshooting has been also made to just
apply on devices that can't emit ::scroll-begin/end.
This is a GtkEventController implementation to handle mouse
scrolling. It handles both smooth and discrete events and
offers a way for callers to tell their preference too, so
smooth events shall be accumulated and coalesced on request.
On capable devices, it can also emit ::scroll-begin and
::scroll-end enclosing all ::scroll events for a scroll
operation.
It also has builtin kinetic scrolling capabilities, reporting
the initial velocity for both axes after ::scroll-end if
requested.
This change is made for consistency, it doesn't make sense to expose
one-way propagation, as it can only break expectations from GTK+. This
function might be made entirely private in the future, but it still
makes sense to do this in one go for our internal usecases.
This will allow further cleanups and optimizations in capture/target/bubble
event delivery. For simplicity, ATM every widget will receive its own
GtkEventControllerLegacy, it could be desirable to add finer control over
this in the future, so widgets that fully use event controllers for input
management can do away without this legacy piece.
As Benjamin says, ident should only be used if any value
is valid, which is not the case here. So use enums instead,
which should also be more efficient. To handle the more
complicated cases like font-variant-ligatures, we have to
introduce flags-like values.
Clarify that ::destroy, not ::hide*, removes a window from its app, by
replacing the mention of open windows with the blurb on destruction from
:application, completing commit 7db4bee4b6
Also link to the equivalent gtk_application_(add|remove)_window() calls,
since Application.add_window() already links back to Window:application.

It was never unref()d, either when replacing the existing GObject in
set_property(), cleaning up in finalize(), or becoming a placeholder.
Fix by using g_set_object() and g_clear_object() to unref as needed.
This also drops the check that the newly set object is a valid cloud
provider account, as we don’t do the equivalent for any of the other
object-typed properties, and Carlos didn’t think this was important.

Drop the current css2-style font-variant property and
replace it with a shorthand as specified in the css3 fonts
module. Currently, we fully support the font-variant-ligatures,
font-variant-position, font-variant-caps, font-variant-numeric
and font-variant-east-asian subproperties. font-variant-alternatives
is only partially supported.
Instead of relying on special values of edge constraints, this
patch adds an internal-only gdk_window_supports_edge_constraints()
function that by default returns FALSE, and is implemented by
GdkWindowWayland and GdkWindowX11.
This way, we can properly detect server-side support for this
feature and adapt accordingly.

The last touch on this patch series is making GtkWindow able to
selectively adjust various UI details based on the different
tiled edges. The main driver here is that we don't want to show
shadows on edges that are constrained.
This patch adds the necessary code to do that, while still
maintaining compatibility with the old ways.
https://bugzilla.gnome.org/show_bug.cgi?id=783669
GTK windows don't have their tiling states really
hooked into the client-side decoration code, and
the only effect it has is disabling the resizing
edges.
With the introduction of per-edge tiling information,
we are backed by much more precise data on how the
window manager wants the app to behave.
This patch, then, fixes GtkWindow to take into account
per-edge tiling information. For compatibility purposes,
the previous tiled field was kept, and thing will just
continue working if no edge information is supplied.

The outline-{top,bottom}-{left,right}-radius names have been
deprecated for a while, so lets remove them. Everybody should
just use the -gtk-prefixed names for these properties.
The focus outline disappeared as the colour of the swatch got close to
the normal focus outline colour, which is alpha(currentColor, 0.3).
Fix by making the outline an alpha’d version of the tick colour, but
more opaque than normal outlines. 0.6 seems good enough; feel free to
improve it, but at least this ensures the outline can’t vanish anymore.
HighContrast achieves this already because it applies the color property
to the main node, not the overlay. Doing that means the outline is fully
opaque, which is fine for HC obviously but was excessive for Adwaita.

It used $text_color unconditionally, but in :dark, text is white, so we
overlaid a white tick on any light colours, all the way to white itself.
Using these named colours doesn’t make practical or semantic sense.
Instead, use white/black over dark/light swatches, as in HC, so all
variant–swatch combos work. Light looks the same, & :dark works now.
For backdrop, use alpha 0.5, unlike 0.7 in HC, as that seemed excessive
& different from the current effect. 0.5 is almost identical to how
$backdrop_fg_colour is a 50% mix of $fg_color, & matches backdrop text.

On Python-3.x, we need to set the encoding when opening files, when this
script is run, as it might contain items that are not supported by the
system's locale (for example, non-English Windows). So, we use a
wrapper to set the encoding on Python 3.x, but open the file as we did
when using Python 2.x, since file encodings are not supported there.

along the orthogonal orientation. It seems a FlowBox on its own can only
handle being shrunk along its main orientation. The orthogonal requests
a huge min size – reserving what it would need if the main orientation
got its min size, which would flow all children in 1 line orthogonally.
Adding it to a ScrolledWindow (any policy) enables free shrinking, so
size_allocate() can reflow how users in this situation probably expect.

Without specifically connecting ::delete-event to something, the dialog
will be destroyed when it is closed, for example by pressing Esc. This
meant that when dismissing it this way, unlike by pressing Cancel, any
custom palette would be lost when the dialog was next opened, and so on.
Resolve this by making ::delete-event just do GTK_RESPONSE_CANCEL, so
closing the dialog has the same effect as clicking its Cancel button.

This commit takes several steps towards rendering text
like we want to.
The creation of the cairo surface and texture is moved
to the backend (in GskVulkanRenderer). We add a mask
shader that is used in the next text pipeline to use
the texture as a mask, like cairo_mask_surface does.
There is a separate color text pipeline that uses the
already existing blend shaders to use the texture as
a source, like cairo_paint does.
The text node api is simplified to have just a single
offset, which determines the left end of the text baseline,
like all our other text drawing APIs.
