Since the addition of GdkEventSequence in touchpad events, these
are now stored in the gesture using that sequence. This bit of touchpad
gesture handling was however missing to be updated, still looking up
the special NULL sequence.
Use the last sequence here, which will be the one coming from touchpad
gesture events.
Despite touchpad gestures having a sequence, these must use the logical
pointer focus. Avoid using the sequence for GtkPointerFocus lookups with
those events, in order to ensure those events make it all the way to the
intended target.
This is fallout from adding GdkEventSequence information to touchpad
gestures.
Currently when the widget is realized after the focus in event the input
method isn't activated as enable is never sent. The call trace is
gtk_text_focus_changed ->
gtk_im_context_focus_in ->
gtk_im_context_wayland_focus_in
which returns early as self->widget is NULL since it's set up in
gtk_text_realize() via gtk_im_context_set_client_widget(). Handle that
case by invoking gtk_im_context_focus_in() from gtk_text_realize() too.
A case where the above happens is a GtkSearchEntry in a GtkSearchBar.
E.g. in gtk4-demo when starting the demo and then hitting the search
button right away.
Remember the current context on focus-in even though the text-input
isn't set up yet. This helps in the case where the text-input is not yet
created but a widget already got focused. Without that the enable()
invocation in text_input_enter() woulnd't be invoked leaving the input
method disabled.
This fixes
gtk4-demo --run=search_entry
which would initially not show the on-screen keyboard when e.g using
phoc/sway as compositor.
Make GtkIMContextIME ignore ASCII control characters just like other
IMContext implementations (e.G. GtkIMContextSimple). Fixes bogus
characters appearing in text input fields (old bug 676077).
Unref private spool_io of GtkPrintJob before setting it to a new one
in gtk_print_job_set_source_file() and gtk_print_job_set_source_fd()
to prevent a leak.

Instead of relying on the iso-codes package, use the native Windows NLS APIs to
acquire the localized (translated) language names so that we do not need to
incur an extra runtime dependency on Windows. It's not coverering 100% of the
languages that we would like to support through this, but should cover much of
the things that are required.
We aren't really using PangoFT2 for [language|script]-names.c, and are
always using items from them, so make sure they are being built.
Also always include the pangoft2 dependency in gtk_dep if it is found.
We were handling events in the wrong order,
by doing async calls for some of them, but not
for all of them.
And we were not taking into account that GFileMonitors
RENAMED events may or may not move a file on top
of an existing file.

clang-tidy says:
gtklabel.c:1188:15: warning: Although the value stored to 'mid' is used in the enclosing expression, the value is never actually read from 'mid'
min = mid = text_width;
^ ~~~~~~~~~~
Which seems right since mid will be assigned to at the beginning of the
next loop iteration anyway.
If we have a GDK_ACTION_MOVE, we need to delete the selection. However,
previously this only worked when the drop target and drag source were
different applications, as the selection would get messed up along the
way.
Instead, we stash marks for the duration of the operation so that we can
delete the appropriate selection when completing the move.
The change to use ld and objcopy for resources
had some side-effects: it leaked a few symbols
and made our stack executable. We don't want that.
Use -z nonexecstack and --strip-all to avoid this.

Everything that makes use of gtk_printer_settings_get should be nullable
Because the hashtable might not contain the key and there's no default value provided
Pango may not do this for us, so don't rely on it.
We only show one face with a given name, and we
prefer a variable face over a non-variable one.
The check for variable faces requires new Pango
API that will be in Pango 1.52.
Allowing to tweak the axes of named instances does
not do any harm. If we don't, we have to worry that
we need at least one non-named-instance in the face
list, and make it more obvious how to pick it out.
If the application window is measured with for_size -1 horizontally,
this code clearly passes something lower to the parent class measure()
implementation. Only subtract the menubar_height if we're passed a
for_size > -1.
This has lots of issues:
* It randomly crashes when data is loading while the dnd goes away.
* The data gets randomly reset at the wrong time
* Can't scroll the window on Wayland
* ...
But it's better than nothing, so better get it committed.
After performing an action such as undo/redo, we need to actually scroll
to the position where the operation occurred.
I do note that the scroll here seems to often get invalidated if it is
pages away, and we never make the full scroll. But I've seen this all over
the place elsewhere too and that needs to be handled, most likely, as a
more comprehensive fix for scrolling during line validation.

It's cheap to store the selection position, so always set it even if we
are in a user section. Otherwise, we risk not having the right position
when starting a delete action within a begin_user_action(),
end_user_action() pair.

At last as long as widgets like GtkFlowBox and
GtkGrid still trigger this, it is not a great
idea to have this warning in a stable release.
So remove it for 4.6
Generates a graph visualizing calls to gtk_widget_measure().
Generation of the graph can be slow - like when it forces Pango to wrap
a huge label 1000s of times.
You can dnd the graph to look at it closer or to impress people in
gitlab issues.
It makes sense to connect the begin/update/end events
for touchpad swipes and pinches in a sequence. This
commit adds the plumbing for it, but not backends
are setting sequences yet.
We now require a Pango version that requires Visual Studio 2015 or later to
build, and non-UCRT-based (VS2013) binaries may not bode well with
UCRT-based binaries (VS2015+). Drop the support for VS2013 as a result.
This reverts commit e208e0e07886248d4d86118aa5591c9882f0ed5c.
We run into trouble on X11 if the widgets
in the drag icon have drop targets attached.
Prevent this by suppressing event delivery
to drag icons outright.
We were sometimes ending printer enumeration prematurely,
and the code was confused about the meaning of found_printer.
The new setup follows these rules:
- We *only* end the search prematurely if found_printer
is set, which indicates that we found the right printer
- We *always* call find_printer_idle exactly once, and
make it return less than perfect matches like the
default printer, or the first printer we found

If we've already done the tracking into the parent muxer, there is no need
to do it again. This can save a great deal of recursive work when adding
items to the muxer.
This makes showing the context menu in gnome-text-editor repeatedly fast
even as spelling corrections are changed.
It is likely that this could fix#4422 as well.

When handling action-added callbacks the code was previously using a
freeze_notify/thaw_notify in all cases. This turns out to allocate a
significant amount of memory when called a lot.
That said, it shouldn't be getting called this much but given the current
state of affairs elsewhere in GtkActionMuxer, this brought temporary
allocations down from 9MiB to 9KiB in gnome-text-editor after showing
the context menu a few times.
Related #4422
Instead of allocation width for height for width for height or whatever
that code was doing, actually allocate the size we were given or the
requested size, whatever is larger.
Don't just pass on measure() calls, but actually behave in the way we
behave during size allocate.
This should improve cases where GtkScrolledWindow is used with GTK_POLICY_NEVER.
We want this to take precedence in the wayland platform to other
modules that might be loaded via the IO extension point. None of
those is going to bode well in this platform.

This adds a new row to the Global/Information section which displays the
GTK im-module that is likely to be in use unless changed by an application.
It responds to updates of GtkSettings:gtk-im-module unless the
GTK_IM_MODULE environment variable is set.

When returning surrounding context to input methods,
include at least 2 words before and after the insertion
point.
Update the affected input method tests.
If we set the placeholder text before setting a buffer, we end up with
both the placeholder *and* the buffer's contents visible at the same
time.
Fixes: #4376
We use gtk_gesture_get_last_event() underneath at places that need to
work during ::proximity emission. Since GtkGesture only tracks events
while there are button/touch presses involved, this is not going to
bring the right result there.
Use gtk_event_controller_get_current_event() consistently inside,
which always pokes at the event being handled (which is the correct
intent here).
The idea of within-margin is to scroll as little
as possible to bring the mark within the margins
defined by the factor. The code was achieving
that when scrolling down, but not when scrolling
up. This change makes things symmetrical.
Fixes: #4325
It turns out we can't just use the size returned
by the memory stream as-is, since it may contain
unfilled garbage at the end, which utf8 validation
will choke on. So, cut it off at the first '\0'
we find.
When the iter is at the end of the buffer,
gtk_text_view_get_iter_location returns a
rectangle with width 0, which in turn makes
gdk_rectangle_intersect return FALSE.
Avoid that by always giving the rectangle
non-empty dimensions.
Fixes: #4503
Setting variations to their default value causes
them to show up in the serialization of the font
description - a font description has no idea about
the default values, so can't filter them out.
Avoid that.
Try to compute a min size that matches the current aspect ratio.
This means that when interactively resizing, we adapt the min size to
the current window area dynamically.
And that means that we always have a min size that is large enough, but
users can interactively cause it to be small-width x large-height,
large-width x small-width or anything inbetween.
Printing the affected widget leads people to assume that it is to blame
for the error. However, the widget is the object the function is being
called on, not the caller. And the caller is doing it wrong.
Usually the caller is the parent widget, so we could print that one, but
it's only usually, it can be an issue propagating from a grandparent and
it doesn't tell you from where the function is called (allocation or
measuring), so you need a debugger anyway.
So don't put anything there instead.
When the stack is homogeneous in only one direction, the other direction
may produce min sizes to small for all children. Make sure to query at
least the min size for those.
If halign=fill, force adjustment to height-for-width.
If valign=fill, force adjustment to width-for-height.
Otherwise look at request mode.
This way we don't try to adapt the filled dimension and only adjust
the one that is not set to fill.
It's not expensive to check it because we'll cache the dfault size
request anyway, and people do it wrong a lot.
As a bonus, don't do any return_if_fail(), just use the min size
instead.
When the compose file is a symbolic link, take the link itself's
modification time into account (in addition to its target's) in
determining whether to invalidate the compose cache.
This is useful e.g. on NixOS systems where the compose file might point
to a store path with an irrelevant modification time, and we want the
cache to expire when the symlink itself changes.
This grab-induced crossing event may come from outer means while there are
buttons pressed (e.g. WM window drags/resizes in X11), the implicit active
state should be undone in that situation.
Also, separate the handling of GDK_LEAVE_NOTIFY, as it's fundamentally
different from GDK_TOUCH_END/CANCEL handling.

The sequence should be cancelled from the gesture despite its current state.
Also, there was a piece of pointer emulation that was not dropped here,
maybe breaking things further for the pointer emulated touchpoint.

We only want to determine the size pixel-exact, not pango-unit-exact, so
don't spend lots of time wondering if text is half a pixel or a quarter
pixel wider.
Assume a vbox with 2 wrapping labels saying
Hello World
Hi Ho
being measured for their minimum width for 3 rows of text.
This should be layouted like
Hello
World
Hi Ho
and measured accordingly.
However, previously this was layouted as
Hello World
Hi Ho
with 1.5 lines being assigned to both labels.
That will obviously not compute the above wrapping which clearly
results in a smaller min width.
A reftest testing exactly this was included.
... when they are wrong.
Instead, remove them.
Or in other words: GTK4 does not have a fill child property anymore, so
we don't need to run the measuring loop above to determine the size.
This reverts commit cf7fa931d3.
We store the baseline in the cache and we do not know if baselines might
be queried in the future. So always store them.
No reftest because I don't know how to write one.
premature optimization == √😈
