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.
We delegate the size request mode, the measuring, and the allocation of
a widget through a GtkLayoutManager instance, if one has been attached
to the widget; otherwise, we fall back to the widget's own implementation.
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.
Add a ::show-peek-icon property and show a clickable
icon when it is set. Clicking it toggles the visibility
of the content. The same functionality is also accessible
via a context menu item.
This is a common feature of password entries.
In particular, add a per-category querying API for the matrix:
- gsk_transform_to_translate()
- gsk_transform_to_affine()
- gsk_transform_to_2d()
- gsk_transform_to_matrix()
This way, code can use the relevant one for the given category.
Change gdk_surface_get/set_user_data to private
API and rename them to get/set_widget.
Also remove an unused associated function.
The last two places where the surface API is used
are in gtkroot.c and gtkwidget.c. Make them
use the private api.
This is a first cut at updating the drawing model chapter
for the way we do things now. It introduces the scene graph and
render nodes, explains node caching and tree diffing, and removes
sections about subwindows.
Instead of gtk_snapshot_offset(), provide a full set of functions
kept in sync with GtkTransform APIs.
On top of that, add gtk_snapshot_save() and gtk_snapshot_restore()
mirroring cairo_save()/restore() that allow saving a snapshot's
transform state.
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.
Use a GtkText child, and delegate the editable functionality
to it. Also forward all the properties that are provided by
GtkText.
Some of the more internal APIs, such as layout and im context
access and caps-lock warning, are removed here, but we preserve
most of the plain GtkEntry API by forwarding it to the GtkText
child.
The transform matrix is a translation matrix from the parent's origin to
the widget origin. We will later allow more transformations than just
translations.
Change the reorder api to insert after a sibling,
so that moving to first place becomes reorder (... NULL).
And add a insert_after api that can replace the common
container_add / reorder_after (... NULL) combination.
Update all callers.
Instead of using the INCLUDE directive inside the sections file, we can
specify the default C include in the gtkdoc-mkdb arguments, and override
it inside the C sources that need it.
As stated by the documentation, this should be called when a widget gets
updated, but in that case, one can equally use
gtk_widget_trigger_tooltip_query.
The complexity with model items vs row items is really confusing. Add to
that treelistmodel position vs child model position vs parent position,
and you're so confused, even the best naming can't help.
And once you're there, consider passthrough vs non-passthrough...
Remove gtk_menu_popup_for_device() and gtk_menu_popup(), as they cannot
be implemented in a portable manner by all backends. They have been
deprecated for proper alternative APIs for some time, so lets remove
them now before its too late.
While at it, fix the example documentation for mapping a menu.
7733f646d6 renamed GdkDragContext to
GdkDrag, which broke the docs, as a reference to
gdk_drag_context_get_type() still exists. This commit renames the type
accordingly and adds GdkDrop.
In particular, this patch removes:
gdk_surface_get_events()
gdk_surface_set_events()
gdk_surface_get_device_events()
gdk_surface_set_device_events()
Event masks so far still exist for grabs.
This uses the new method without GDK_ACTION_ASK:
Either it is a single action (queryable via gdk_drag_action_is_unique())
or it is not and then the drop target has to make a decision
(potentially by asking someone).
Unconditionally putting 'gdkwayland_inc' in src_dir argument of gtkdoc
call tells gtkdoc-scan to scan source files in a non-existent build
directory, gdk/wayland. To avoid causing build failure when a specific
backend is disabled, we should include directories conditionally.
and gtk_image_set_can_shrink().
Images are meant to always be icon-sized, they can never shrink below
that.
And images are icons, so they are meant to be square. If they are
not, we pretned that's by accident and keep aspect ratio.
This commit introduces GtkPicture, which is supposed to complement
GtkImage.
GtkImage will be adapted to always display an icon, while
GtkPicture displays regular imagery.
1. Include the broadway renderer (so we can test it properly fails on
Wayland or X11)
2. List all potential renderers, print useful information when Vulkan
is not compiled in instea dof omitting it
3. Improve docs
to retreive paper size specific hard margins and use this
to set the hard margins in the print context.

This makes the previous gdk_draw_context_is_drawing() function public
under a new name.
I decided against the old name because we use the term "frame" for a
drawing operation, so I wanted to have this boolean flag reuse the term.
As they require a draw context and the draw context is already bound to
the surface, it makes much more sense and reduces abiguity by moving
these APIs to the draw context.
As a side effect, we simplify GdkSurface APIs to a point where
GdkSurface now does not concern itself with drawing anymore at all,
apart from being the object that creates draw contexts.
This does nothing but disallow passing NULL to gdk_surface_begin_paint()
and instead require this context.
The ultimate goal is to split out Cairo drawing into its own source file
so it doesn't clutter up the generic rendering path.
And of course, gsk_render_node_get_name() is gone, too.
The replacement is of course debug nodes.
As a side effect, GskRenderNode is now *really* immutable.
When filing a new merge request it's often hard to know who to ask for a
review; using the Git log doesn't always help — the person that touched
a file last may just be fixing the build or a compiler warning.
The `CODE-OWNERS` file format is something that GitHub uses in order to
pre-fill the list of reviewers:
https://help.github.com/articles/about-codeowners/
Ideally, in the future, we'll be able to use this file with a bot like
homu to automatically go through newly filed merge requests and
automatically ask the relevant people for reviews, instead of doing this
manually.
If you want to draw a widget to cairo today, you create a widget
paintable, snapshot it to a render node and then draw the render node to
cairo.
And yes, this is that complicated on purpose. Don't draw widgets to
Cairo.
Instead of calling gdk_surface_invalidate_region(), just
gdk_surface_queue_expose() and rely on the renderer computing the diff
from the previous rendering.
It doesn't need to be exported anymore.
As a side effect, the inspector no longer has any information about the
render region, so remove the code that was taking care of that.
This is the equivalent snapshot function to pango_cairo_show_layout().
Not to be confused with gtk_snapshot_render_layout(), which is the
equivalent to gtk_render_layout().
If you want transparent region, you can just render them transparent.
If you want input shaping, use gdk_surface_input_shape_combine_region().
Also remove gtk_widget_shape_combine_region().

This is necessary so that bidnings work properly and don't make
gdk_gl_texture_release() a function on GdkTexture.
It also allows code to identify what type of texture they are dealing
with.
Finally, we can now decide to add getters later without screwing
anything up, if we want to allow people to access GL textures directly.
If set, the image will draw its contents while keeping their aspect
ratio. That means empty areas show up on the top/bottom or left/right.
Also move the special-case snapshotting code for icons to
GtkIconHelper. That's where it belongs.
The internal known_globals hashtable is used to carry accounting for
interfaces that depend on others (as ordering is not guaranteed), extend
its usage so it also keeps track of unimplemented interfaces (here at
least).
The API call will then use this to allow querying the globals offered by
the compositor, it will be useful to determine whether we can use
text-input protocols or should fallback to other IMs.
Since part of our type system is resolved at run time, we need to use
run time facilities to get diagnostic messages, like deprecation
warnings for properties and signals.
We should mention the G_ENABLE_DIAGNOSTIC environment variable in the
migration guide, to let developers know how to catch deprecations and
changes while porting their code.
- Make the rules for including headers explicit
- Make the symbol visibility rules explicit, and drop the
old "leading underscore" hack
- Drop Private data structure declarations and priv pointers
from public headers
- Mention G_DECLARE_* macros
- Mention `#pragma once`
