It is enough to just set the parent (and make the parent
call gtk_native_check_resize in size_allocate).
This commit removes the relative_to argument to the
constructors of GtkPopover and GtkPopoverMenu, and
updates all callers.
This is in particular relevant for the ::is-focus property, because
updating that one doesn't cause enter/leave events.
But it also checks that notify and enter/leave happen in the right
order.
Split the focus tracking into a separate
GtkEventControllerFocus, and change the API one more time.
We are back to having ::focus-in and ::focus-out signals.
Update all users.
Add properties, and use string arrays instead of lists.
Among other things, this renames gtk_icon_theme_list_icons
to gtk_icon_theme_get_icon_names.

This tests was testing gestures by faking an event in the
middle of a window that has a hbox with an expanding image in it.
For me (and I guess this depends on all sorts of issues like whether
CSD is enabled, font sizes, etc) the hbox ended up centered horizontally
but not vertically (probably because of csd at the top), so no events
ever hit the inner widgets.
This is fixed by emitting the events at allocation.x/y of the
hbox, which should contain both the hbox and the image (as it expands).
We test this by looking at the produced render nodes now that
we don't actualluy scale the icon. Also, it turns out that this
code was broken due to some typos, so we also fix those.
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.
Stylecontexts are on their way out and I'm removing API that the
testsuite was relying on, so remove the tests.
Put the useful parts of the tests elsewhere.
Instead, rely on people passing fallbacks explicitly.
Alternatively, GThemedIcon provides the functionality to create
fallbacks, which is what GtkImage and the testsuite now use.
That method is slightly better, too, so the expected test results
have been updated accordingly.
There is no way to query contexts or do anything useful with them.
So don't keep track of them and don't make them an argument in public
APIs with the docs saying "I don't know what to use here, maybe read
some spec somewhere".
We expose no API to get at any colors for drawing symbolics, so we
shouldn't have APIs to draw with them.
Apart from that, those APIs look like a box of crayons, not like an
icontheme.
Most users were just forgetting to set the proper flags.
And flags aren't the right way to set this anyway, it was just
acceptable as a workaround during GTK3 to not break API.
The API encouraged wrong usage - most of the users were indeed wrong.
Use the correct version instead:
gtk_icon_theme_get_for_display (gtk_widget_get_display ())
