This removes the GDK_CONFIGURE event and all related functions and data
types; it includes untested changes to the MacOSX, Win32 and Broadway
backends.
This removes the gdk_surface_set_shadow_width() function and related
vfuncs. The point here is that the shadow width and surface size can now
be communicated to GDK atomically, meaning it's possible to avoid
intermediate stages where the surface size includes the shadow, but
without the shadow width set, or the other way around.
Setting a field on a class structure is not always an easy task from
languages other than C. While bindings can provide access to the class
pointer, twiddling the fields in the class structure can be awkward.
Additionally, signal ids are not always readily available.
We can paper over the direct access to the class structure, as well as
the "signal name to id" mapping with a simple couple of setter
functions.
First of all, we must list *all* ignored headers. Since we have public
headers in the x11 and wayland directories, we must explicitly declare
all headers that we consider private under those directories.
The "quartz" subdirectory was renamed "macos", with the new macOS
backend. The "mir" directory was removed, so there's no need to ignore
it.
We are also missing a bunch of ignored headers in the top-level gdk
directory.
Finally, pass the list of ignored files to gtkdoc-mkdb, so we won't get
missing declaration warnings.
GtkTreeView.get_tooltip_context() takes an inout X and Y coordinates,
but the "out" side is a side effect: the conversion from widget-relative
to bin window-relative coordinates is not documented, and can be done
using public API, if needed.
GtkIconView.get_tooltip_context() follows the same pattern, and takes
two inout arguments for the coordinates, but it does not change them any
more, after GtkIconView's bin window was dropped in commit 8dc5e13e.
There's really no point in having these `inout` arguments, and while
GtkTreeView and GtkIconView are certainly de-emphasised in GTK4, and we
nudge developers to move to the new list views, we should take advantage
of the API break to remove warts.
Currently GTK can be built with G_ENABLE_DEBUG which enables various debug code and parsing
of those env vars, or without, which instead of parsing them prints a warning if they are set.
While building with G_ENABLE_DEBUG isn't strictly needed it's the only way to make GTK_DEBUG=interactive work,
which is a nice thing to have always.
This enables parsing of those env vars in any case and allows specific values being marked as also
available when not built with G_ENABLE_DEBUG (interactive for example). If not built with G_ENABLE_DEBUG
then all unavailable values will be marked as such in the help output and a note is added that
GTK needs to be built with G_ENABLE_DEBUG to use them, which should help discoverability.
Use a single environment variable for everything:
- select the ATContext implementation
- select the test ATContext
- disable ATContext entirely
We use the same pattern as GSK_RENDERER, GTK_DEBUG, etc.
The documentation needs to be updated to include the environment
variable.
