It's old and busted, and mostly broken in weird ways when it comes to
extended input devices. All that XIM does, these days, is make a mess
when people enable it by mistake.
Remove the unneeded is_platform() check and just go by extension point
priority.
Also g_error() out if no im module exists, because "simple" is compiled
in and should always exist.
The code would technically allow loading the xim module when X11 support
was not compiled in.
This is probably an artificial concern, because it's pretty hard to
compile XIM support without X11 support, but it makes the code clearer,
so there we go.
…the wayland registry.
Wnen _gtk_im_module_get_default_context_id calls
match_backend (context_id) and the default GdkDisplay
is wayland, match_backend() should return TRUE only if
gdk_wayland_display_query_registry (display, "gtk_text_input_manager")
returns TRUE.
When generating introspection data, we instantiate types without
calling gtk_init, so make sure that extension points are registered
before the type is trying to implement them.
Add an extension point called gtk-im-module, which requires
the type GtkIMContext. Simplify the loading by using GIO
infrastructure. Drop the locale filtering for now, I don't
think it is really necessary nowadays.
Convert existing platform modules to gio modules.
Sill to do: Drop the conditional build machinery.
Either always include them, or never.
This was added a few years ago, as a way to have _no_ im context
at all. But it didn't actually work. Make it work, and streamline
the handling of none by moving it all to gtkimmodule.c.
As part of this, add context to the translated names of all
im modules we ship.
We add a custom im module for broadway that calls some broadway
specific APIs to show/hide the keyboard on focus in/out. We then forward this
to the browser, and on the ipad we focus an input field to activate
the keyboard.
GTK+ tries to automatically assign the best input module based on the
'system locale'. In the specific case of the IME input method, it will
be the default for the whole GTK+ application if the system locale is
either Japanese (ja), Korean (ko) or Chinese (zh). Other defaults are
equally applicable, e.g. if system locale is Catalan (ca), the special
'Cedilla' input module is chosen.
System locale can be changed (e.g. Win7) through the following sequence
(reboot required):
Control Panel
Region and Language
Administrative
Language for non-Unicode Programs
Change system locale...
The problem with this behaviour is that changing the 'default input
language' (e.g. from English to Japanese+IME) doesn't affect the GTK+
application. Therefore, I can have an English system locale (where GTK+
will choose Simple IM by default) but then have Japanese+IME as input
language.
Default input language can be changed (e.g. Win7) through the following
sequence (no reboot required):
System locale can be changed (e.g. Win7) through:
Control Panel
Region and Language
Keyboards and Languages
Keyboards and other input languages
Change keyboards...
Default input language can also be changed using the language bar directly.
So, instead of using the system-wide default locale to decide which input
method to use as default, better use the input language specified by the
user, which may be the same as the system-wide default locale, or different.
Following the previous example, with an English system locale and a
Japanese+IME input language, the default input method will now be IME
instead of Simple, which is closer to what's expected by the user.
This change only affects the application during startup; i.e. if the user
changes the input language while the application is running, we wouldn't be
changing the default input method to use. We could do this processing the
WM_INPUTLANGCHANGE messages, though.

With multiple GDK backends in the process, we run into problems where
we try to use the Wayland im module on X, which crashes. This commit
adds a quick backend filter that removes the wayland, xim and ime
input methods from consideration unless the corresponding GDK backend
is in use.
This code is called early on, without a window, and then later on
with a window. Currently, it returns different results for these
cases when the setting contains a value. That leads to pointless
construction and destruction of im contexts. Instead, just look
at the settings of the default screen. In practice, there is only
one screen, ever.
Move the remaining struct definition into gtkimcontextinfo.h and include
that header in gtk.h. gtkimmodule.h is now an empty header. We should
probably deprecate it somehow.
This is also necessary so headers used in gtk .c files don't include
gtk.h which in turn includes all the deprecated headers which we want to
avoid so we can include them with deprecation warnings turned off.
Make includes not rely on gtkimmodule.h including gtk.h. This will be
important once we remove gtkimmodule from the include files.
That way, we can achieve not pulling deprecated headers automatically.
- add gtkmodulesprivate.h and move stuff there from gtkprivate.h
- add gtkprivate.c and move stuff there from gtkmain.c
- add gtkwin32.c and move stuff there from gtkmain.c
- don't redefine GTK_DATADIR and friends in gtkprivate.h
- have _gtk_get_datadir() and friends on all platforms
- remove the horrid hacks where gtkprivate.h can't be included,
or must be included later due to redefinition of the compile-time
directories
