Language bindings—especially ones based on introspection—cannot deal
with custom type hiearchies. Luckily for us, GType has a derivable type
with low overhead: GTypeInstance.
By turning GskRenderNode into a GTypeInstance, and creating derived
types for each class of node, we can provide an introspectable API to
our non-C API consumers, with no functional change to the C API itself.
The proper way to do this would be to adapt the tables
to have the right data for the platform. Since 4.0 is
a new start in many ways, lets clean this up.
We don't need all of them, only the ones that contain public API. This
allows us to reduce the chance of a stray symbol getting incorrectly
added to the introspection data.
This broke when the event type check in gdk_key_event_matches
was removed and replaced by a precondition that accepts both
key press and release events.
Add the check in gtk_keyval_trigger_trigger instead.
Our new approach to modifiers works with a fixed set,
there is really no need to customize the modifier
masks if the backends are all supposed to deliver
the same modifiers.
This removes the use of the context menu and shift group
intents in gdkevents.c. If it turns out to be important,
we need to introduce vfuncs for gdk_event_triggers_context_menu
and gdk_event_matches.
Reviewing the existing settings, the only backend with
some differences in the modifier intent settings is OS X,
and we would rather have that implemented by interpreting
the existing modifiers in the appropriate way.
X11 Wayland Win32 OS X
primary ctrl ctrl ctrl mod2
mnemonic alt alt alt alt
context menu - - - ctrl
extend sel shift shift shift shift
modify sel ctrl ctrl ctrl mod2
no text alt|ctrl alt|ctrl alt|ctrl mod2|ctrl
shift group varies - - alt
GTK now uses the following modifiers:
primary ctrl
mnemonic alt
extend sel shift
modify sel ctrl
no text alt|ctrl
The context menu and shift group intents were not used
in GTK at all.
Update tests to no longer expect <Primary> to roundtrip
through the accelerator parsing and formatting code.
This code needs to be redone differently, since keymaps are no
longer going to be exposed. There should really not be this much
ifdef-ed backend-specific code here anyway. Or any, really.
Add all of the keyboard translation results in the key event,
so we can translate the keyboard state at the time the event
is created, and avoid doing state translation at match time.
We actually need to carry two sets of translation results,
since we ignore CapsLock when matching accelerators, in
gdk_event_matches().
At the same time, drop the scancode field - it is only ever
set on win32, and is basically unused in GTK.
Update all callers.
The win32 backend is using GDK_MOD2_MASK for AltGr,
so define GDK_MOD2_MASK locally to keep this working,
but remove any mention of GDK_MOD3_MASK,...,GDK_MOD5_MASK.
These are never used in practice, and we never want to
see them in the UI, so stop supporting them. This is
in preparation for cleaning up GdkModifierType.
