A radiobutton without indicator is really just a togglebutton with a
group.
A radiobutton with indicator is really just a checkbutton with a group.
Make checkbutton its own widget not inheriting from GtkButton.
GtkRadioButton could be removed but it stays for now.
Radiobutton && !draw-indicator => Togglebutton
Checkbutton && !draw-indicator => Togglebutton
Radiobutton && draw-indicator => CheckButton + group
To build a better world sometimes means having to tear the old one down.
-- Alexander Pierce, "Captain America: The Winter Soldier"
ATK served us well for nearly 20 years, but the world has changed, and
GTK has changed with it. Now ATK is mostly a hindrance towards improving
the accessibility stack:
- it maps to a very specific implementation, AT-SPI, which is Linux and
Unix specific
- it requires implementing the same functionality in three different
layers of the stack: AT-SPI, ATK, and GTK
- only GTK uses it; every other Linux and Unix toolkit and application
talks to AT-SPI directly, including assistive technologies
Sadly, we cannot incrementally port GTK to a new accessibility stack;
since ATK insulates us entirely from the underlying implementation, we
cannot replace it piecemeal. Instead, we're going to remove everything
and then incrementally build on a clean slate:
- add an "accessible" interface, implemented by GTK objects directly,
which describe the accessible role and state changes for every UI
element
- add an "assistive technology context" to proxy a native accessibility
API, and assign it to every widget
- implement the AT context depending on the platform

Make Alt-e the mnemionic for both the Edit menu
and the Select button on page 2. This shows that
mnemonic cycling doesn't currently work, we always
open the menu.
The flowbox demo is otherwise less than useful,
if /usr/share/gnome/backgrounds isn't present.
At the same time, give the scale in the listbox
some function.
Change which rows in the listbox on page 2 are activatable,
and trigger a dialog. It did not really make sense that this
would happen when clicking on the spin button to focus it.
We have example cut/copy/paste actions for which we want
the usual shortcuts to show up in the menus, but they should
not break the expected shortcuts in entries. So, move them
to a capture phase shortcut controller.
The designers wanted the frame column gone for a long
time, since inset/outset/groove etc are not the coolest
features anymore.
Keep one frame, and put a GtkVideo in it.
This opens up some real estate on page 1. Suggestions
welcome for how to fill it.
