This is an enum that we're gonna use soon and it's worth introducing as a
separate commit.
The intention is to have meaningful names for return values in
comparison functions.
Users provide a search filter and an expression that evaluates the items
to a string and then the filter goes and matches those strings to the
search term.
GtkExpressions allow looking up values from objects.
There are a few simple expressions, but the main one is the closure
expression that just calls a user-provided closure.
With this, the expand_content_files list has been
completely converted to markdown files. Whats left
in content_files is man pages, and a few special
cases.
Arrange for files named section-foo.md to be turned
into docbook sections, while others get turned into
chapters. This is necessary to allow including such
content in chapters, since chapters in docbook don't
nest.
As part of the conversion, give up on including
sources files from the examples directory, and
instead include the content directly. All include
mechanisms add complications. They were already
complicated with xml, and markdown is not making
things easier.
We already did that for fragments, and if you
make changes to these example sources, you
probably need to revise the surrounding text
anyway.
Use pandoc to convert freestanding markdown files to docbook for
inclusion in the generated docs, and use bits and pieces of
gtk-doc code to continue expanding typical gtk-doc abbreviations.
The new tool for markdown -> docbook is a python script called
gtk-markdown-to-docbook.
The markdown dialect is specified via a list of pandoc extension
in gtk-markdown-to-docbook. It includes header annocations,
definition lists and tables, among other things.
This commit converts the 3 overview chapters (drawing, input
handling and actions) and the migration guide to markdown
syntax. Other files that are still listed in content_files
can be converted later.
This commit adds a pandoc dependency.
Drop apis and code related to appmenus from
both GtkApplication and GtkApplicationWindow.
We still keep the menubar support, since it
is needed for system integration on OS X.
Fixes: #2731
We are using floating point for coordinates
everywhere now, so be consistent here.
This commit also changes the implementation of
gtk_fixed_get_child_position to work with
non-translation child transforms.
Nested main loops are bad, as they introduce layers of complexity caused
by the potential re-entrancy in the case of multiple event sources, like
IPC, threads, etc. Additionally, the programming model they provide—stop
the world while spinning a new loop—does not conform to the event-driven
model employed by GTK.

Redo this series of examples from 2013, and adapt it to modern
way of doing things. The biggest differences are that we use
a headerbar right from the start, and don't mention the app
menu.
Fixes: #2730
Add back a property that determines whether an individual
widget will accept focus or not. :can-focus prevents the
focus from ever entering the entire widget hierarchy
below a widget, and :focusable just determines if grabbing
the focus to the widget itself will succeed.
See #2686
Use window title, or custom title widget if it's set. Remove 'title'
property.
Update demos and tests to set the title on the window instead of
headerbar.
This gives us a hook to walk the widget tree whenever a global
setting changes and do per-widget invalidations. This will
replace gtk_style_context_reset_widgets().
This was only living in gtkcontainer.c for historic
reasons. Move it closer to where it belongs, and
rename it from 'idle' to 'layout', since it is
really about the layout phase of the frame clock,
nowadays.
Make GtkAspectFrame not derive from GtkFrame anymore,
since frames now always draw, well, a frame. Also,
add proper setters for the properties of GtkAspectFrame.
Update our sole user.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/2627
The viewport draws a frame at the same place as
the scrolled window, so there is really no need
to have that ability in both. Just drop the frame
from viewports.
GdkEvent has been a "I-can't-believe-this-is-not-OOP" type for ages,
using a union of sub-types. This has always been problematic when it
comes to implementing accessor functions: either you get generic API
that takes a GdkEvent and uses a massive switch() to determine which
event types have the data you're looking for; or you create namespaced
accessors, but break language bindings horribly, as boxed types cannot
have derived types.
The recent conversion of GskRenderNode (which had similar issues) to
GTypeInstance, and the fact that GdkEvent is now a completely opaque
type, provide us with the chance of moving GdkEvent to GTypeInstance,
and have sub-types for GdkEvent.
The change from boxed type to GTypeInstance is pretty small, all things
considered, but ends up cascading to a larger commit, as we still have
backends and code in GTK trying to access GdkEvent structures directly.
Additionally, the naming of the public getter functions requires
renaming all the data structures to conform to the namespace/type-name
pattern.
Make this a full async function, and add a simple wrapper.
Call gtk_show_uri_full() if you need control over the
results, and use gtk_show_uri() if you are fine with
ignoring any errors.
We have event controller apis to replace these.
There is one remaining use of gtk_get_current_event_time
in gtkwindow.c, so we can't drop the implementation yet.
Add a section in the migration guide for this.
Our new approach to modifiers works with a fixed set,
there is really no need to customize the modifier
masks if the backends are all supposed to deliver
the same modifiers.
People should use shortcut controllers instead (global, capture).
A side effect of this is that GtkAccelLabel now lost its method to
magically look up accelerators to display. Somebody needs to add that
back later.
This is mainly for internal use, but I can't see a reason to not have it
public for people who want to maintain their own lists.
I'm sure gnome-builder will never ever find a way to misuse it.
When creating shortcuts, there almost always are a trigger and an action
available for use. So make gtk_shortcut_new() take those as arguments.
Also add gtk_shortcut_new_with_arguments() so people can easily pass
those in, too.
Similar to GtkShortcutTrigger, GtkShortCutAction provides all the
different ways to activate a shortcut.
So far, these different ways are supported:
- do nothing
- Call a user-provided callback
- Call gtk_widget_activate()
- Call gtk_widget_mnemonic_activate()
- Emit an action signal
- Activate an action from the widget's action muxer
It's an outdated technology now that everybody is using GActionGroups.
If somebody wanted to support changeable shortcuts, they'd need to
reintroduce it in another way.
This adds an interface for taking care of shortcut controllers with
managed scope.
Only GtkWindow currently implements this interface, so we need to ensure
that we check if any top-level widget we reach is a shortcuts manager
before we call into it.
Mnemonics need to be triggered with help from the controllers (who
determine the modifiers). Support for that has been added, too.
Mnemonics do not use this yet though.
Allow setting the scope for a controller. The scope determines at what
point in event propagation the shortcuts will be activated.
Local scope is the usual activation, global scope means that the root
widget activates the shortcuts - ie they are activated at the very
start of event propagation (for global capture events) or the very end
(for global bubble events).
Managed scope so far is unimplemented.
This is supposed to be used to replace accelerators and mnemonics.
This is a very barebones controller that currently does nothing but
activate the binding signals. Yay.
And because we have bindings on every widget (Yes, a GtkGrid has a
keybinding - 2 in fact), we need that controller everywhere.
This function is the replacement for
gtk_binding_entry_add_signall().
The GVariant will be demarshalled and passed to the action signal upon
binding activation. The same rules apply as used to apply for
GtkBindingArg, in that long, double and string args are now replaced by
"x", "d" and "s" variant types.
Add an api to retrieve the model containing a given
item in a flatten listmodel. This is useful when the
individual items in the list don't have backpointers.
