9ab83cebfd drag-action: Capture stage leave
If we are dragging, we don't want the drag handle to emit a
::leave-event even if the pointer left the stage.

8d51617979 Conditionally use g_object_notify_by_pspec
This adds a wrapper macro to clutter-private that will use
g_object_notify_by_pspec if it's compiled against a version of GLib
that is sufficiently new. Otherwise it will notify by the property
name as before by extracting the name from the pspec. The objects can
then store a static array of GParamSpecs and notify using those as
suggested in the documentation for g_object_notify_by_pspec.

Note that the name of the variable used for storing the array of
GParamSpecs is obj_props instead of properties as used in the
documentation because some places in Clutter uses 'properties' as the
name of a local variable.

Mose of the classes in Clutter have been converted using the script in
the bug report. Some classes have not been modified even though the
script picked them up as described here:

json-generator:

 We probably don't want to modify the internal copy of JSON

behaviour-depth:
rectangle:
score:
stage-manager:

 These aren't using the separate GParamSpec* variable style.

blur-effect:
win32/device-manager:

 Don't actually define any properties even though it has the enum.

box-layout:
flow-layout:

  Have some per-child properties that don't work automatically with
  the script.

clutter-model:

  The script gets confused with ClutterModelIter

stage:

  Script gets confused because PROP_USER_RESIZE doesn't match
  "user-resizable"

test-layout:

  Don't really want to modify the tests

fd27ca7398 Mark property strings for translation
Both the nick and the blurb fields should be translatable, for UI
builders and other introspection-based tools.

62c08b4a09 drag-action: Disable picking during drag
While dragging we don't need to perform picking to determine the actor
underneath the pointer, for two reasons:

  • we use a capture on the stage to determine the motion delta.
  • we know the actor underneath the pointer because that's the
    actor we are dragging around.

This change should make dragging actors in complex scenes a bit faster.

f97d16cd2d drag-action: Remove the press event button
Both ::drag-begin and ::drag-end have a "button" argument - even though
we assume internally, and externally, that dragging can only be the
result of a primary button operation.

b2c905ff50 Hide the marshallers
The marshallers we use for the signals are declared in a private header,
and it stands to reason that they should also be hidden in the shared
object by using the common '_' prefix. We are also using some direct
g_cclosure_marshal_* symbol from GLib, instead of consistently use the
clutter_marshal_* symbol.

b77c0c91d7 drag-action: Re-use press_button in emit_drag_end()
Since emit_drag_end() can be called from a MOTION event capture we
cannot call clutter_event_get_button(). We should, instead, use the
press_button value because if we're emitting ::drag-end it means we
also emitted ::drag-begin and the value is valid.

cfb05bfb09 docs: Fix DragAction documentation
The ::drag-motion signal does not have a ModifierType argument; also,
there's no need to connect to the ::drag-motion signal any more.

728e2d8071 drag: Add a default drag-motion behaviour
The DragAction should, by default, drag the actor to which it has been
applied, instead of delegating what to do to the developer. If custom
code need to override it, g_signal_stop_emission_by_name() can be called
to stop the default handler to ever running.

4fd74e71e6 action: Add DragAction, an action implementing drag capabilities
DragAction is an Action sub-class that provides dragging capabilities to
any actor. DragAction has:

  • drag-begin, drag-motion and drag-end signals, relaying the event
    information like coordinates, button and modifiers to user code;

  • drag-threshold property, for delaying the drag start by a given
    amount of pixels;

  • drag-handle property, to allow using other actors as the drag
    handle.

  • drag-axis property, to allow constraining the dragging to a specific
    axis.

An interactive test demonstrating the various features is also provided.
