We require a C compiler supporting C99 now. The main purpose of
these fallbacks was for MSVC. From what I can see this is now all supported
by MSVC 2015+ anyway.
The only other change this includes is to replace isnanf() with the
(type infering) C99 isnan() macro, because MSVC doesn't provide isnanf().
If you run weston with the headless backend, you get a Wayland
display with no seat, which is just fine by the protocol.
gdk_display_get_default_seat() returns NULL in this case. Various
widgets assume that we always have a seat with a keyboard and a
pointer, since that is what X guarantees. Make things survive
without that, so we can run the testsuite under a headless
Wayland compositor.
Add back a property that determines whether an individual
widget will accept focus or not. :can-focus prevents the
focus from ever entering the entire widget hierarchy
below a widget, and :focusable just determines if grabbing
the focus to the widget itself will succeed.
See #2686
Emit accessible change signals after setting the
new selection limits. This was broken in
commit f6bedd0d5e, and showed up as broken
accessibility tests.
Always track visited state of links. This way all visited links in all
labels look the same. Whether the theme wants to style :visited is the
theme's business.
This makes it more obvious that gtk_label_setup_mnemonic() depends on
the root of the widget and it therefore makes sense to call it in
::root/::unroot.
Don't allocate a new GString if we never need it and therefore don't
create the PangoAttrList if we have no attributes anyway. Update callers
to handle the possible NULL return value.
We don't really have an event anywhere close in most
cases, and we already pass GDK_CURRENT_TIME in half
the cases anyway.
If we want to be serious about this, we need to pass
the event itself, since future focus-stealing protocols
may not rely on just a timestamp.
Add a .link style class on labels that contain links,
so we can avoid the focus outline around the label
when individual links are focused, and use the link
node when rendering the focus on links.
