The "iconified" state is mostly an X11-ism; every other platform calls
this state "minimized" because it may not involve turning a window into
an icon at all.
The new check/radio style increased their specificity, but it was not
synchronized in the menu styling.
This commit increases the specificity to match the updated check/radio
styling.

- Adjust the emoji picker appearance to be the same as gtk3's.
- Fix button.emoji-section margins in RTL.
- Prevent the .emoji hover effect from being applied to the entire
nested popover.
The signal handler that calls notify_child_cb() is disconnected
from a child widget before the child is removed from the header bar.
gtk_header_bar_dispose() chains up before destroying the start and end
boxes, thus avoiding calls to notify_child_cb() after start_box and
end_box have been cleared.
Fixes#2246
A GtkBox in a titlebar could have unwanted spacing.
This caused a glitch in split-header applications where
parts of the titlebar would be transparent or black.
This commit tweaks Adwaita to make sure no spacing is added for boxes when used as titlebars.
Fixes#2233
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
GTK uses the Meson `buildtype` option to determine whether to enable or
disable debugging code and safeties. We should document our behaviour
and expectations.
This adds support using the GtkTextHistory helper for undo/redo to the
GtkText widget. It is similar in use to GtkTextView, but with a simplified
interface.
You can disable undo support using the GtkText:enable-undo property. By
default, it is enabled.
This changes the semantics of ::deleted-text to perform the removal of
text in the default handler. This means, that if you want the old behavior
where your signal handler is called after the text has been deleted, you
should connect with G_CONNECT_AFTER in your signal handler (or use
g_signal_connect_after).
Without this change, there was never a way to get the deleted-text before
the operation had completed and this is necessary to provide undo support
to the text widgets.
This builds upon the GtkTextHistory helper to provide undo and redo support
for the GtkTextView widget and GtkTextBuffer object.
You can undo/redo using familiar shortcuts such as Primary+Z,
Primary+Shift+Z, ad Primary+Y.
Developers that wish to disable undo, should set the
GtkTextBuffer:enable-undo property to FALSE.
You can wrap irreversible actions
gtk_text_buffer_begin_irreversible_action() and
gtk_text_buffer_end_irreversible_action(). This will cause the undo stack
to drop all undo/redo actions and the changes made between them will be
the "initial state" of the buffer.
Calling gtk_text_buffer_set_text() will do this automatically for you.
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.
