This is to go along with the newly introduced GdkDrop.
This commit includes the necessary updates to the X11, Wayland
and Broadway backends. Other backends have to be updated separately.
Instead of doing all handling manually in the ::event vfunc,
set up drag/multipress gestures on icon images, and implement
emission of ::icon-press/release and DnD there.
As a side effect, the GdkEvent field in ::icon-press/release
signals has been dropped. Callers that might be interested on it
may still use gtk_get_current_event*().
All of the four platform-dependent backends are enabled by default. It
is usually a good default because it requires users to explicitly choose
backends they want to use. Rules in meson.build also automatically
disable unavailable backends for macOS, Windows, Linux, so users on
these 3 major platforms don't have to manually disable things when
running meson commands.
However, meson.build doesn't do the same thing for other Unix-like
systems, which is acceptable but not ideal. To make it easier to build
GTK+ on these systems, the Linux case, which enables X11 and Wayland and
disables Win32 and Quartz, is made the default for all operating systems
that are not Windows or macOS.
This commit also changes most 'host_machine.system()' calls to os_*
variables, which are easier to read and less likely to be used wrongly.
This allows being more specific about the size.
It's useful in particular when the resulting render nodes might be
too small for the size, not only when they are too large. For the
latter case, using a clip node would be enough.
It also requires adding a clip node when rendering the resulting
paintable, but that should be optimized out by GtkSnapshot when not
necessary.

is_touchpad_device() for XI2 was hardcoded to look for libinput only.
Extend it slightly to correctly identify other Xorg touchpad drivers.

This used to test that "windowed widgets" and "non-windowed widgets"
handle alpha correctly, but none of the mentioned widgets are windowed
at all anymore. For the rest, this is more easily and dynamically
testable by simply using the inspector.
The border is now drawn on the frame node, not using an internal border
node, so we are no longer able to align the label to vertically overlap
the border. The property no longer performs its original purpose, & nor
is it a useful candidate for giving a new role, so no point keeping it.

So we can use that one when translating event coordinates. Also adapt
the widgetfocus demo to ensure this works.
We should probably at some point delete either the int or the double
version.
Load random strings from /usr/share/dict/words instead of reusing the
same 10 words all the time. That way, we get closer to the real world
use case of having a full alphabet.
The main GDK thread lock is not portable and deprecated.
The only reason why gdk_threads_add_timeout() and
gdk_threads_add_timeout_full() exist is to allow invoking a callback
with the GDK lock held, in case 3rd party libraries still use the
deprecated gdk_threads_enter()/gdk_threads_leave() API.
Since we're removing the GDK lock, and we're releasing a new major API,
such code cannot exist any more; this means we can use the GLib API for
installing timeout callbacks.

This test was not updated to using a draw func instead
of the ::draw signal yet. At the same time, make it use
::size-allocate instead of ::configure-event.
1) Add a --compare cmd line switch that lets people compare the normal
render path and the render_texture path.
2) Add a -o cmd line switch that lets people render the given .node
file to a texture and save that texture to the given png file name.
This is in preparation of using input streams to show that these
coordinates aren't needed most of the time and can otherwise be saved
during GtkWidget::drag-drop.
This is a GSList of GFile and we want it so we can operate with lists of
files and text/uri-list.
I chose GSList over GList because that's what the GtkFileChooser API
uses, too.
Instead of having just one function that has the gtype and mime type as
out arguments, have 3 functions: 1 that finds any match, 1 that finds a
GType match and one for a mime type match.
This makes the API way more convenient to use.
This requires implementing a "pipe" so we can have 2 streams running:
contentprovider => serializer => outputstream
inputstream => deserializer => reader
And the pipe shoves the data from the outputstream into the inputstream.
GdkContentProvider is the object that represents local data in the
clipboard.
This patch only introduces the object and adds the clipboard properties,
it does not yet provide a way for the actual implementations to access
it.
The only access that is implemented is the local shortcut GValue access.
This allows us not just to pass any mime type to the read function, but
it also makes it possible to pass multiple mime types and the clipboard
can then try them in order until it finds a supported one.
This is so far not implemented though.
It's unused. Plain text is not using that framework, neither is
in-process same-display transmission.
So it was only useful for sharing text with custom tags across
applications, and nobody is doing that.
This is not used by anything yet, but add it now, so people looking at
this new code can make sense of it.
Plus, the documentation mentions it, so better have the docs make sense.
It will be used once we add support for conversions to GDK and allow
doing cipboard/dnd by GValue.
Make sure the API reflects the idea that GdkContentFormats is a set
containing mime types. In particular, treat the object itself as a
plural - it's named content format`S' after all - and therefor use
the correct verb form.
Also make GdkContentFormats keep an array instead of a list, now that
it's immutable.
Instead of allowing people to pass a uint user-data, insist on them
comparing mime types.
The user data was a uint instead of a pointer anyway, so uniqueness
could not be guaranteed and it caused more issues than it was worth.
And that's ignoring the fact that it basically wasn't used.
Instead, add a function gtk_image_set_icon_size() for the cases where
overriding the icon size is necessary.
Treat icon sizes the same way as pixel sizes, too. So gtk_image_clear()
no longer unsets the icon size.
Instead of returning the icon size with them, make
gtk_image_get_icon_name() and gtk_image_get_gicon() only return the icon
itself.
As a benefit, we can turn them into regular getters that return values
instead of requiring out parameters.
Instead, provide gtk_image_get_icon_size() to query the icon size.
Change constructors to reflect that.
While doing so, also add a fallback argument to the cursor constructors,
so it is now possible to create cursors with fallback.
And have a priv->display instead of a priv->screen.
Includes turning gtk_menu_set_screen() into gtk_menu_set_display(),
because that function just forwards to its window.
This drops the pixbuf property and the pixbuf getters. We keep
gtk_image_new/set_from_pixbuf, but these are small helpers that
immediately convert to a surface, and there is no way to later get
back the pixbuf you passed in.
The from file/resource codepaths are also changed to load a surface
instead of a pixbuf.
Rename the surface getter to peek, following other render
node getters, and make the surface-based constructor private,
since it is not something we want to encourage.
Update all callers.
GtkMenu’s own keynav code, which actually bothers to account for the
layout of items, only happens if columns > 1. So, adding items to 1
column using a reverse loop meant they were placed in the Menu’s list of
children in that order, and because we only have 1 column, Menu passes
keynav up to MenuShell, which doesn’t adjust for the items’ positions.
‘Fix’ that here by adding items in the same order they’ll have when laid
out in the Menu, so keynav does what you’d expect, not the opposite. For
that, it’s simpler just to use gtk_container_add().
Let’s presume users are using add(), attach() with a non-inverted loop,
or attach() with arguments that create 2+ columns and so GtkMenu keynav.
Ditch two items that were white and so weren’t visible on our standard
theme anyway, and use the new space to test extra grid-mode properties.
Note that if we do this then, as before, we set the ListStore on the
ComboBox before appending to it, that produced runtime warnings like:
Gtk-CRITICAL **: gtk_menu_attach: assertion 'left_attach < right_attach' failed
I didn’t look into that yet, but it may indicate that attaching items
vs. recognising their spans don’t occur in the correct order. For the
purposes of testing this, I just create the CB after filling its model.
The ComboBoxes were initially empty, rather than reflecting the initial
values of the properties. The CheckButtons were only correct by chance.
Fix this by setting the initial values on the widgets and binding them
to the properties using SYNC_CREATE, so the two are always synced up.
