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".
Those functions are unused and the documentation says "Returns some
random number that the icon theme creator chose" which does not seem at
all useful and an implementation detail.
So get rid of it.
We're not in the business of adding Cairo APIs. That's Cairo's job.
Also, we don't need this API anywhere like the original commit claimed,
so there's no need to make it available in any way.
This reverts commit afa6cc2369.
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 ())
All the a11y tests were failing for me with a window state diff
like this:
- state: active enabled resizable sensitive showing visible
+ state: enabled resizable sensitive showing visible
I guess the windows in the CI always gets the focus, but not when
I run it here. Generally focus seems asynchronous and hard to rely
on so I just made the test ignore the active state on toplevels.
These days initilizing gtk may create a connection to the sesson bus,
so we have to initialize GTestDBus before initalizing gtk, or we'll
use the address of the "real" session bus (and remember that in the
global).
To further muck things up, g_test_dbus_up() resets important env
vars like DISPLAY and XDG_RUNTIME_DIR, which we have to re-set.
This was blocking the clean exit from the testdbus shutdown in
the defaultvalues test. The proxy was keeping the connection alive
which blocks g_test_dbus_down().
Fix up the index computation. We have duplicate entries
in the type enum, so to go from one of the 'initial' types
to it corresponding type you subtract one, but to find
the size array entry for a type, you divide by 2.
It turns out with the icon cache now using the virtual SYMBOLIC_PNG_SUFFIX
flag the two enums are now identical, so lets just use one of them, the
one GtkIconCache (so we move it to the header).
This adds a GDK_DEBUG=default-settings flag which disables reads
from xsettings and Xft resources, and enables this for the testsuite.
This is one less way to get different testresults depending on the
environment. In particular, it was failing the css tests for me
due to getting the wrong font size because i have a different dpi.
This is a useful widget to have, and it has minimal api.
Not having it public forces apps to recreate a lot of
complicated machinery for not good reason, if they need
an Emoji chooser in a different context.
Traditionally the icon lookup for a theme has been:
lookup (icon_name, size):
best_directory = NULL
forearch theme
foreach directory in theme
if dir_size_matches (directory, size) && dir_has_icon (directory, icon-name)
best_directory = chose_best_size_dir (best_directory, directory)
if best_directory
return icon from best_directory
However, it turns out that there are a lot of subdirectories which have the same
size, as they differ only in the (essentially useless) "context" value. For example
the "16x16/apps" subdirectory is essentially the same as the "16x16/actions" one.
So, instead rathern than keeping all the directories as separate we store the
all the directories with the same size as a single entity (DirSize) and the
icon lookup in that DirSize looks up not only which suffix to use for that icon
but also which subdir it is in.
Additionally we keep a hashtable with all icon names that are
available in the entire theme (i.e. all DirSizes), which allows use
both to store each icon name only once, but also to do a quick
negative lookup and early exit in case we're looking up an icon that
doesn't exist. This is pretty common because we often look up sets of
icons like "image-png-symbolic", "image-png", "image", expecting some
to fail.
This brings down the time of the initial css validation from 20msec to 15msec for
me when running icon-factory.
This lists the icons in a particular director, with their flags in a
hashtable. We also convert from "icon.symbolic" + SUFFIX_PNG to
"icon" + SUFFIX_SYMBOLIC_PNG.
This avoids the build from erroring out on C4819 (Unicode handling issue in
Visual Studio compiler), notably when running on Chinese, Japanese and
Korean locales.
Also apply -D_USE_MATH_DEFINES, -FImsvc_recommended_pragmas.h and -utf-8 to
the C++ compiler options as well.
We only have implementations of this on X11 and Win32,
so make it available as backend api there.
Update all callers to use either the backend api, or
just monitor 0.
Instead of requiring sassc to be installed add meson subprojects
which build libsass and sassc (currently both forks of mine, tested
under linux/mingw/msvc) when needed.
This allows us to drop the generated .css files and build scripts from git.
