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.
This commit handles complicated cases where we selections.
We handle this by adding extend and modify parameters to
the ::move-cursor signals, and adjust the bindings
accordingly.
After the :can-focus change in the previous commit, widgets
need to set suitable focus and grab_focus implementations
to implement the desired focus behavior.
This commit does that for all widgets.
Make widgets can-focus by default, and change the semantics
of can-focus to be recursive . If it is set to FALSE, focus
can not enter the widget or its descendents at all anymore.
This commit temporarily breaks focus behavior of widgets
that did not expect to receive focus.
Reviewing the existing settings, the only backend with
some differences in the modifier intent settings is OS X,
and we would rather have that implemented by interpreting
the existing modifiers in the appropriate way.

primary ctrl ctrl ctrl mod2
mnemonic alt alt alt alt
context menu - - - ctrl
extend sel shift shift shift shift
modify sel ctrl ctrl ctrl mod2
no text alt|ctrl alt|ctrl alt|ctrl mod2|ctrl
shift group varies - - alt
GTK now uses the following modifiers:
primary ctrl
mnemonic alt
extend sel shift
modify sel ctrl
no text alt|ctrl
The context menu and shift group intents were not used
in GTK at all.
Update tests to no longer expect <Primary> to roundtrip
through the accelerator parsing and formatting code.
This is a huge reorganization of GtkDropTarget. I did not know how to
split this up, so it's unfortunately all one commit.
Highlights:
- Split GtkDropTarget into GtkDropTarget and GtkDropTargetAsync
GtkDropTarget is the simple one that only works with GTypes and offers
a synchronous interface.
GtkDropTargetAsync retains the full old functionality and allows
handling mime types.
- Drop events are handled differently
Instead of picking a single drop target and sending all DND events to
it, every event is sent to every drop target. The first one to handle
the event gets to call gdk_drop_status(), further handlers do not
interact with the GdkDrop.
Of course, for the ultimate GDK_DROP_STARTING event, only the first
one to accept the drop gets to handle it.
This allows stacking DND event controllers that aren't necessarily
interested in handling the event or that might decide later to drop
it.
- Port all widgets to either of those
Both have a somewhat changed API due to the new event handling.
For the ones who should use the sync version, lots of cleanup was
involved to operate on a sync API.
It’s possible for code which uses a `GtkListBox` to reuse a single
header row, and move it around between rows. For example, this might
happen if the code has interactive widgets (like buttons) in the row,
and doesn’t want to continually recreate them and reattach signals to
them whenever the row headers change.
Unfortunately, this was broken, as the old header widget was
unconditionally unparented, even if it had just been set as the header
for a different row in the same `GtkListBox`. This left it assigned as
a child widget in the `GtkListBox` (so it was iterated over by
`forall`), but without its parent widget set.
Fix that by only unparenting the header if it hasn’t already been
assigned as the parent of a different row.

We don't need to cover every case with a va_marshaller, but there are a
number of them that are useful because they will often only be connected
to by a single signal handler.
Generally speaking, if I opened into a file to add a va_marshaller, I just
set all of them.
Similar to previous removals of g_cclosure_marshal_VOID__VOID we can remove
other marshallers for which are a simple G_TYPE_NONE with single parameter.
In those cases, GLib will setup both a c_marshaller and va_marshaller for
us. Before this commit, we would not get a va_marshaller because the
c_marshaller is set.
Related to GNOME/Initiatives#10
If we set c_marshaller manually, then g_signal_newv() will not setup a
va_marshaller for us. However, if we provide c_marshaller as NULL, it will
setup both the c_marshaller (to g_cclosure_marshal_VOID__VOID) and
va_marshaller (to g_cclosure_marshal_VOID__VOIDv) for us.
Signal emittion was added in 6f857f87dc commit and it seems that
this is only place where selected_row is set after emitting signal.
Because of this gtk_list_box_get_selected_row currently returns NULL
as selected row if selection mode is set to GTK_SELECTION_BROWSE.
Unparenting a GtkListBoxRow can drop its last reference, which
will free its memory. Right after unparenting, though, we were
accessing the row's iter - which assumes that the row is still
alive. This causes a crash when, for example, binding two or
more models to the listbox.
Fix that by storing the iter in a variable, and not trying to
access it after unparenting. After unparenting, the variables
that are potentially garbage were explicitly assigned NULL for
clarity.
