This is a GtkRoot implemntation for drag icons,
using the surface provided by GdkDrag. This lets
us avoid GTK_WINDOW_POPUP and
gtk_window_set_hardcoded_surface.
GtkBuilderScope is an interface that provides the scope that a builder
instance operates in.
It creates closures and resolves types. Language bindings are meant to
use this interface to customize the behavior of builder files, in
particular when instantiating templates.
A default implementation for C is provided via GtkBuilderCScope (to keep
with the awkward naming that glib uses for closures). It is derivable on
purpose so that languages or extensions that extend C can use it.
The reftest code in fact does derive GtkBuilderCScope for its own scope
implementation that implements looking up symbols in modules.
gtk-widget-factory was updated to use the new GtkBuilderCScope to add
its custom callback symbols.
So it does it different from gtk-demo, which uses the normal way of
exporting symbols for dlsym() and thereby makes the 2 demos test the 2
ways GtkBuilder uses for looking up symbols.
We use a compilation symbol in our build to allow the inclusion of
specific headers while building GTK, to avoid the need to include only
the global header.
Each namespace has its own compilation symbol because we used to have
different libraries, and strict symbol visibility between libraries;
now that we have a single library, and we can use private symbols across
namespaces while building GTK, we should have a single compilation
symbol, and simplify the build rules.
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.
Some of the CSS API has been moved to a public namespace, so we need to
include it into the introspection data we build in order for people to
use it.
Fixes: #2230
The GtkTextHistory helper provides the fundamental undo/redo stack that
can be integrated with other text widgets. It allows coalescing related
actions to reduce both the number of undo actions to the user as well as
the memory overhead.
A new istring helper is used by GtkTextHistory to allow for "inline
strings" that gracefully grow to using allocations with g_realloc(). This
ensure that most undo operations require no additional allocations other
than the struct for the action itself.
A queue of undoable and redoable actions are maintained and the link for
the queue is embedded in the undo action union. This allows again, for
reducing the number of allocations involved for undo operations.
This creates a new GtkTextViewChild that can manage overlay children at
given x,y offsets in buffer coordinates. This simplifies GtkTextView by
extracting this from GtkTextWindow as well as providing a real widget for
the borders.
With this change, we also rename gtk_text_view_add_child_in_window() to
gtk_text_view_add_overlay(). For those that were using
GTK_TEXT_WINDOW_WIDGET, they can use a GtkOverlay. It does not appear
that anyone was using GTK_TEXT_WINDOW_(LEFT|RIGHT|TOP|BOTTOM) for widgets
in this fashion, but that can be done by setting a gutter widget with
gtk_text_view_set_gutter(). We can make GtkTextViewChild public if
necessary to simplify this should it become necessary.
GtkTextViewChild will setup a CSS node of either "text" or "border"
depending on the GtkTextWindowType.
The old GtkTextViewChild has been renamed to AnchoredChild as it is only
used for widgets with anchors in the GtkTextBuffer. This also removes the
use of allocated GSList and instead embeds a GQueue and GList to save a
few extraneous allocations.
This adds a GtkTextLineDisplayCache which can be used to cache a number
of GtkTextLineDisplay (and thus, PangoLayout) while displaying a view.
It uses a GSequence to track the position of the GtkTextLineDisplay
relative to each other, a MRU to cull the least recently used display,
and and a direct hashtable to lookup display by GtkTextLine.
We only cache lines that are to be displayed (!size_only). We may want to
either create a second collection of "size_only" lines to speed that up,
or determine that it is unnecessary (which is likely the case).
This removes the use of GtkTextDisplay (a PangoRenderer) to use
the GskPangoRender which generates render nodes. Part of this means
improving the GskPangoRenderer to support the necessary features for
displaying a GtkTextView.
Primarily, this is a merging of GtkTextDisplay features into
GskPangoRender. Additionally, GtkTextDisplay was removed to allow for
gtk_text_layout_snapshot() to be implemented elsewhere.
This commit moves GtkConstraintGuide into its own
source files to avoid gtkconstraintlayout.c turning
too messy, adds max size properties and implements
getters and setters.
GtkConstraintSolver is an implementation of the Cassowary constraint
solving algorithm:
http://constraints.cs.washington.edu/cassowary/
The Cassowary method allows to incrementally solve a tableau of linear
equations, in the form of:
x = y × coefficient + constant
with different weights, or strengths, applied to each one.
These equations can be used to describe constraints applied to a layout
of UI elements, which allows layout managers using the Cassowary method
to quickly, and efficiently, lay out widgets in complex relations
between themselves and their parent container.
The only cases of stateful actions we've seen
so far have been boolean properties, and we
don't really want to add much state handling
API, so lets just go with property actions
for now.
Adapt the only user in GtkText.
This library is meant to be the new CSS library that gets used from GDK,
GSK and GTK for string printing and parsing.
As a first step, move GtkCssProviderError into it.
While doing so, split it into GtkCssParserError (for critical problems)
and GtkCssParserWarning (for non-critical problems).
The need of a specialised fixed layout container that can be placed into
a GtkScrolledWindow ceased to exist once GtkScrolledWindow gained the
ability to automatically interpose a GtkViewport when adding a child
that does not implement GtkScrollable.
All the other justifications that led to the existence of GtkLayout as a
separate widget from GtkFixed have been largely made irrelevant in the
20 years since its inception.
- Rename GtkLegacyLayout to GtkCustomLayout
- Use for() to iterate over children in GtkBinLayout
- Whitespace fixes for code imported from GtkBox
- Store the GtkLayoutChild instances inside LayoutManager
- Simplify the GtkLayoutManager API by dropping unnecessary arguments
- Fix the ownership model of GtkLayoutManager
GtkLegacyLayout is a layout manager for the transitional period between
the introduction of layout managers and the removal of GtkWidget virtual
functions for the size negotiation.
Layout managers needs a way to store properties that control the layout
policy of a widget; typically, we used to store these in GtkContainer's
child properties, but since GtkLayoutManager is decoupled from the
actual container widget, we need a separate storage. Additionally, child
properties have their own downsides, like requiring a separate, global
GParamSpecPool storage, and additional lookup API.
GtkLayoutChild is a simple GObject class, which means you can introspect
and document it as you would any other type.
A base abstract class for layout manager delegate objects.
Layout managers are associated to a single widget, like event
controllers, and are responsible for measuring and allocating the
children of the widget they are bound to.
This is a new object (well, boxed type, but I'm calling it object) for
dealing with transform in a more constructive way than graphene_matrix_t
by keeping track of how the transform was created.
This way, reasoning about the transform becomes easier, and we can create
better ways to print it or transition from one transform to another one.
An example of this is that while a 0 degree and a 360degree rotation are
both the identity matrix, doing a transition between the two would cause
a rotation.
Build the .rc files for Windows so that one can track the version info
more easily for Windows, as well as giving GTK+ apps a default icon.
Also, move back the manifest embedding for the themed Windows print
dialog back into gtk-win32.rc.body.in, so that we just have one way of
embedding this manifest file, making things easier for ourselves, as
this is supported in the later Visual Studio compilers as well, which is
2013 and later.
This model just takes an object and a property name and recursively
looks it up. In particular, I want it for:
widget, widget.parent, widget.parent.parent, ...
This commit introduces GtkPicture, which is supposed to complement
GtkImage.
GtkImage will be adapted to always display an icon, while
GtkPicture displays regular imagery.
GTK does use libintl directly (in gtkmain.c, for example) and thus
needs to be linked to it (if found and/or needed).
Previously we most likely were getting libintl from glib, but
that stopped for some reason. Either way, explicit linking is
the right thing to do here.
Instead of going through an ancillary script to strip away the
`WL_EXPORT` annotation from the generated code, we should bump up the
required version of Wayland, and use the `private-code` argument for
wayland-scanner, which does the right thing for us.
This is a GtkGesture done to deal with stylus events from drawing tablets.
Those have a special number of characteristics that extend a regular
pointer, so it makes sense to wrap that.
This event controller is meant to replace usage from key-press/release-event
handlers all through. Optionally it can be set a GtkIMContext, so interaction
is carried by the controller.
Really exclude the portions in the gtkfontchooserwidget.c that are built
when HarfBuzz and PangoFT2 are built, and update the Meson files to
exclude such sources as well from the main GTK SO/DLL and from the
gtk4-demo program.

Check for freetype2 version, because pangoft works with any version
(pangoft availability does not indicate that ft2 is new enough), unlike
GTK.
On Windows, since pangoft is optional, we check for the presence of
freetype2 .pc file first after finding that we have pangoft, and then
check for FT_Get_Var_Design_Coordinates() manually by looking for the
freetype headers and .lib first, and then looking for the presence of
that symbol, since freetype2's Visual Studio build system does not
generate a .pc file for us.

This way, we can support external libraries providing implementations of
GtkMediaFile.
We also add a media backend called 'nomedia' that can be enabled to not
compile any support for GtkMediaFile. This is useful when people want to
statically compile GTK into an application that does not use media.
For now, this option is the default.
We also support a new environment variable GTK_MEDIA that allows
selecting the implementation to use.
GTK_MEDIA=help can be used to get info about the available
implementations.
Instead of loading them into surfaces (which we want to get rid of), we
load into textures.
In fact, we introduce a new paintable subclass called a GtkScaler that
takes care of tracking scaling.
This also ideally gets rid of an extra conversion once renderers learn
to render textures directly.
Use that instead of hacks to guess when an image is considered invalid
according to https://drafts.csswg.org/css-images-4/#invalid-image
Also add a GtkCssImageInvalid that implements the behavior of invalid
images according to the CSS spec so thjat image implementations can
refer to that image.
This adds a new GtkStyleAnimation called GtkCssDynamic (for lack of a
better name) that is spawned whenever at least one dynamic value is part
of the GtkCssStyle.
The gir XML file contains description of types and functions from
gtk/gtk-a11y.h. Indicate that this header should be included in addition
to gtk/gtk.h in applications written in C. #56
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.
With autotools the schemas were compiled into each test suite directory
and the tests set GSETTINGS_SCHEMA_DIR to the test build directory.
With meson's gnome.compile_schemas() we can not define a target directory
so just make sure it is built in the gtk directory and set GSETTINGS_SCHEMA_DIR
to the gtk build directory when running the tests.
This makes the gtk+:gtk suite pass when no gtk is installed on the system.
When building dependencies as subprojects we need to tell the
introspection scanner where to find the introspection data; this
means using GIR targets from the subproject.
Instead of using `--include-uninstalled` in the scanner arguments, we
can tell Meson to use an introspection target, and it'll do the
appropriate thing for us.
We need to have two lists: one, with the list of sources that need to be
introspected; and one with the list of sources that contain only private
symbols.
This reduces the amount of source files that the introspection scanner
needs to traverse, and thus the build time.
This is a bit of filechooser internals that gets shared with
nautilus, which is fine, but it shouldn't be part of our
public API. There are no other users than nautilus.
The documentation and annotations for some of the print API is defined
in platform-specific source files, so we need to ensure we're passing
those files to the introspection scanner in order to avoid warnings, and
to get the appropriate introspected API.
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.
With the shader approach to symbolic recoloring, we must
not recolor the svgs anymore as we're loading them. Instead,
load them the same way that gtk-encode-symbolic-svg does.
This fixes the rendering of large symbolic icons e.g. the
'no search results found' page in the file chooser.
This is just lots of renaming.
The interface remains private, so the public API does not change, apart
from removing the definition of the Interface object to avoid
subclassing.
The gtk_tools variable is an array of arrays; adding a new element
requires to maintain the same type, or we'll get a build failure when
we try to extract the newly added element.
Add the necessary machinery into the Meson definition files so that we
can build for Windows.
Since we don't have Wayland or X support for our use case here, disable
them once we know that we are building for Windows, as they are
(otherwise) enabled by default, and enable the items that need to be
built for Windows builds.
Exclude gtk4-launch from Windows builds as that is something that
is not supported on Windows.
As we won't have gio-unix on Windows, and PangoFT2 is optional, don't use
fallbacks for them when we are on Windows (but do use fallbacks for
gio-win32, as it will be used).
Also, clean up meson.build a bit as we can just force-include
msvc_recommended_pragmas.h from GLib since we depend on GLib, and so we
can handle these warnings from msvc_recommended_pragmas.h instead.

This is a GtkEventController implementation to handle mouse
scrolling. It handles both smooth and discrete events and
offers a way for callers to tell their preference too, so
smooth events shall be accumulated and coalesced on request.
On capable devices, it can also emit ::scroll-begin and
::scroll-end enclosing all ::scroll events for a scroll
operation.
It also has builtin kinetic scrolling capabilities, reporting
the initial velocity for both axes after ::scroll-end if
requested.
This will allow further cleanups and optimizations in capture/target/bubble
event delivery. For simplicity, ATM every widget will receive its own
GtkEventControllerLegacy, it could be desirable to add finer control over
this in the future, so widgets that fully use event controllers for input
management can do away without this legacy piece.
Add integration of the libcloudproviders DBus API to the
GtkPlacesSidebar by showing name and sync status of the cloud providers.
The exported menu is rendered as a GtkPopover.
The sidebar will be updated if the list of cloudproviders changes e.g.
by adding or removing an account. If any cloud provider changes detailed
information like sync status only the individual sidebar row gets
updated.

Copy the PangoCairoRenderer into GTK+, rename it to GskPangoRenderer,
and strip it down far enough to build without private pango apis.
This means we currently don't support hexboxes or shapes.
Currently, this lives in gtk, but it might be nicer to put it
in gsk eventually.
GSK has various enumeration types that are currently not used; while
they may go away, currently they are built and introspected. If we want
the introspection machinery to work, and still use static libraries to
build GDK and GSK into the GTK shared library, then we need to reference
the get_type() function of these enumeration types somewhere, to avoid
the linker discarding it, and thus breaking the build.
As luck would have it, we have an autogenerated bit of C that refers to
all the get_type() functions in the library; if we add the GSK types to
it, then we get the reference we're looking for, and the build succeeds.
We're mixing a lot of styles in the Meson build files. This is an
attempt at making everything slightly more consistent in terms of
whitespace and indentation.
We need to check if the linker flags we use are available, depending on
the platform, and we need to ensure that the shared library is
versioned appropriately.
We have to work around some ordering problems here. We still
manage to keep most of the guts in modules/input/meson.build,
so it's not too ugly overall.
(The autotools build solves this with a 'make -C ../../input/modules'
inside gtk/Makefile, but that's not something we can or want to do.)
Add back dependencies on libgdk_dep and libsk_dep which are declared
dependencies. We removed this before because these declarations had
link_with: lines that dragged in the static libgdk.a and libgsk.a libs
which are linked into libgtk-4.so anyway and thus shouldn't be used
when linking internal exes/tools against libgtk-4. Remove the static
libs from the declared dependencies and have libgtk link those in
explicitly, so that the declared deps now just provide all the built
dependencies and include dirs and such for declared libgtk_dep users
such as the internal exes/tools, which want all the generated gsk/gdk/gtk
headers to exist before attempting to compile anything against the
gtk+ headers.
gdk and gsk are no longer separate libs but part of gtk now, so any
Gtk+ user should just link to gtk, there's no need to additionally
link against all those static helper libs that go into the gtk lib.
This means we need to specifically add confinc to include_directories
in more places to make sure the right config.h (i.e. ours) gets
included and not a subproject's like graphene's config.h.
Not dragging in static libs also fixes the issue of all executables
having to be relinked for any and all changes. With this change
it's super-fast now and can be skipped for most changes that don't
touch the external ABI.
This is how it's done in the autotools build. Also avoids problems
with multiple source files having the same name (gdkeventsource.c).
Also move broadway backend code into broadway subdir.
Add libgdk_dep as dependency to the libgtk_dep declare_dependency(), so
that the generated gdk includes are generated before anything is built
that tries to include gtk headers (such as various tests that don't depend
on gdk directly).
This is needed for the Meson port, a file name .c that's included
and shouldn't be compiled into an object is difficult to manage
otherwise. And it's not actually a valid .c file anyway.
