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.
Do kep them for debug and debugoptimized builds though.
Keeping -Werror flags in release builds causes issues with forward
compatibility, when new compiler releases or different toolchains
suddenly cause those warnings to be emitted during compilation.
While we certainly want those issues to be investigated and fixed, they
should not prevent anyone from building GTK until they are.
Resolves#4388
We have a tight coupling with pango, whenever new
pango API appears, our build usually breaks. So
just make our flatpak manifests build pango from git.
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 == √😈
Having a short text and a large max-width-chars should request the
natural width of the text, not the limit from max-width-chars.
This caused huge message dialogs.
Reftests added.
Instead of translating font-variant-caps directly
to OpenType features, translate them to a PangoVariant,
now that that enumeration reflects all the css values.
This allows pango to emulate Small Caps for fonts that
don't support the OpenType feature.
When scrolling embedded widgets out of view,
they sometimes get left behind because we don't
reallocated them. To avoid that, move _all_ children
out of view in size_allocate, and let the current
child allocation plumbing move the visible ones
back in place.
Non-root widgets should unrealize their ATContext, if they have one,
when they are unrooted, as they don't have a connection to a top level
any more.
Fixes: #4421
Use the debug envvar 'GDK_DEBUG=gl-egl' to determine whether we want to try to
initialize EGL first before trying WGL, as a means for people to more easily
enable EGL support on Windows to test EGL there (such as to debug the shaders,
for instance)
This will clean up the EGL code in GDK-Win32, as well as fixing crashes caused
by using an invalid EGL context in gdk_gl_context_make_current() as we did not
store up the EGL context in the correct place (lost during the transition to
the common EGL initialization code).
On the Windows/libANGLE side, the initialization of EGL has now fully moved to
the common code in GDK, but we will still default on WGL for now. Help is
really appreciated for fixing the shaders on libANGLE!
We need to ensure that gdk_display_get_egl_display() is available even if EGL
is not enabled in the build, so that things will continue to link and work.
For builds without EGL, just return NULL.
