The normal way to associate accels with actions is
to attach a shortcut controller to the widget. The shorcut
controller will inject the accel into the action muxer
tree, so that it can get displayed in widgets that activate
the action (say, in menus.
This approach does not works for generated menus, since the
widgets are not in the hands of the app developer, so attaching
shortcut controllers to them is impractical.
Instead, GtkModelButton has an accel property that gets
bound to the accel coming from the action muxer tree (most
likely put there via gtk_application_set_accel_for_action),
and creates a shortcut controller itself.
The change in this commit is to prevent the shortcut controller
from injecting the accel into the action muxer tree in this case.
Otherwise, the accels get 'stuck' and we won't update them if the
global accels are later changed.
This is a hack, and needs a better solution.
We only needed the widget to get its action muxer. And this way we don't
have to call gtk_widget_get_action_muxer() dozens of times, just once in
set_widget().
This is truly a russian doll of documentation formats:
a string containing <> inside an xml fragment in an |[ ]|
gtk-doc example in markdown in a doc comment.
Sadly, something gets escaping wrong, so the <> end up
literally in the docbook and mess up the last step of
our document formatting, even after turning them into
entities.
Work around this with an extra level of entities that
really shouldn't be necessary.
Simplify all view model APIs and always return G_TYPE_OBJECT as the
item-type for every model.
It turns out nobody uses item-type anyway.
So instead of adding lots of APIs, forcing people to think about it and
trying to figure out how to handle filter or map models that modify item
types, just having an easy life is a better approach.
All the models need to be able to deal with any type of object going
through anyway.
Iterate the shortcuts we found in order, not in
reverse. Otherwise, we always end up activating
the last_selected one, since it is last in the
list.
This broke in fb9b54d4b2 when a list was
turned into an array.
Add all of the keyboard translation results in the key event,
so we can translate the keyboard state at the time the event
is created, and avoid doing state translation at match time.
We actually need to carry two sets of translation results,
since we ignore CapsLock when matching accelerators, in
gdk_event_matches().
At the same time, drop the scancode field - it is only ever
set on win32, and is basically unused in GTK.
Update all callers.
Make GtkShortcutController collect matching shortcuts
in the same way GtkKeyHash did (accept fuzzy matches
if we don't have any exact matches), and cycle among
the matches if we have multiple.
Allow GtkShortcutTrigger to return partial matches.
Currently, no triggers produce such results, and
GtkShortcutController treats partial matches like
exact ones.
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.
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
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.
