These are always set to the same value as the corresponding border
radius properties. They are also non-standard, so remove them and
replace them with the border radius properties everywhere.
Fixes#2414
When we are loading symbolic pngs or svgs, we know
that we need to the png or svg loader, so there is
no need to go through (surprisingly expensive) mime
sniffing to find the right loader.
It doesn't really make sense to treat double clicks here different than
single clicks (and is bad UX), and it also breaks switching months by
quickly trying to single-click the last/first days in the calendar.
This is an unused feature that's way too complicated for a default
calendar widget and complicates the implementation a lot. Since we want
to eventually replace this with actual widgets, remove the details
support now.
These will replace the previous gtk_snapshot_new_with_parent(), which
allocated an entirely new GObject just to push()/pop() some state. This
is already a problem but will be more important in the future as we
start using this more.
When reaching this point, it is impossible that all border styles are
HIDDEN or NONE, but up to 3 of them can still be that style. In any
case, the "none or solid" border style is the most common on there is,
so try to make this simpler here by just appending a border node
directly instead of going through the snapshot_border path.
Hide the expensive GTK_IS_ROOT() checks behind the cheaper realized,
mapped, etc. checks. This way we only check for the widget being a root
if the invariant does not hold.
This gets pop_verify_invariants() from 16% to 6% when running the
scrolling benchmark in the widget-factory.
When the css is validated we know the css size, so we can
create the paintable at that point, and we do so passing the
LOAD_IN_THREAD flag.
This causes us to load most icons early on, in parallel instead of
during the first snapshot.
Instead of having the IconTheme have a hashtable that owns
individual strings and then IconThemeDirSize have a similar
hash (but with the strings owned by the other hash), we
have a consecutive memory chunks where we store the icon names
and then the hashtable has pointers into this.
This means we can avoid a bunch of individual strdup()s in a
way that is less fragmented and wastes less space. Additionally,
since we do an initial lookup anyway we have the internalized
icon name during lookup which means we can use g_direct_hash/equal
instead of g_str_hash/equal making the lookup faster too.
If there is a passive grab and the pointer leaves the window we would
receive a GDK_CROSSING_NORMAL event when the pointer moves outside
the window, and a GDK_CROSSING_UNGRAB event when we do release the
button and the implicit grab.
We currently would react to the first, but want to react to the
second. In the time between both events, the client would still receive
pointer motion that will reach the implicitly grabbed widget.

We've started to turns containers into widgets which
just happen to have children, and some of these need
to be exposed to the a11y stack.
This adds a very minimal implementation, it does not
currently emit change notification when children are
added or removed.
These now render the paintable to a cairo surface and convert that
to a texture. This is sort of a hack, but its only used in two
special cases internally and in two hacky test apps.
This changes gtk_text_buffer_insert_texture() to
gtk_text_buffer_insert_paintable() which is strictly more useful
(as textures are paintables). It also fixes the code to actually
support drawing the paintables (as well as tracking changes
to the paintables.
If icon lookup fails or if loading it fails later, just always
fall back to the built in image-missing icon. Nobody is handling
missing icons in a sane way anyway.
If you *truly* need to handle missing icons, you need to manually
use gtk_icon_theme_has_icon().
While changing the loading code I also fixed an issue where it
was always passing "png" to pixbuf, now it also handles "xpm" if
that is the filename suffix.
We had a pretty complex setup where we tried to avoid scaling up themes from dirs
that specified a size. However, not only was it very complex, but it didn't quite
work with window scales, because when using e.g. a size 32 directory for 16@2x
the dir size is wrong anyway. Additionally it turns out most code either picks
an existing icon size, or uses the FORCE_SIZE flags, so it doesn't seem
like a useful behaviour.
This change drops the FORCE_SIZE flags, and always scales
icons. Additionally it moves the scaling of the icon to rendering,
which seems more modern, and allows us to (later) share icons loaded
for different sizes that happened to use the same source file (at
different scales).
Note that this changes the behaviour of
gtk_icon_paintable_download_texture() is it now returns the unscaled
source icon. However, ignore thats, as I plan to remove this function
and replace it with a way to render a paintable to a cairo-surface
instead.
It never makes sense to paint a texture that needs recoloring. If
you call the regular snapshot on a symbolic texture we just use the
default recoloring colors.
To support this we also change gtk_css_style_snapshot_icon_paintable()
to call gtk_icon_paintable_snapshot_with_colors() for IconPaintables
so that we get the correct colors, and we make it not emit the color
matrix.
Since we now rely on the icon to do the recoloring we also drop the
recolor argument in gtk_icon_paintable_snapshot_with_colors() as its
not needed anymore.
When we dismantle our children in dispose, we
trigger a11y children-changed signals which end
up calling back into the notebook. Handle this
without critical warnings.
Only update the action state when we have a text buffer,
there is no need to do it otherwise, since we are going
to get a buffer before we get shown. This avoids triggering
the action state updates from finalize, which is a bad
time to be recreating the action muxer.
The accessible gets properties of the entry, and
resetting the entry icons triggers accessible change
notification, so do that before we dismantle the entry
too far to respond to a g_object_get () call.
