Animation

A base class for animations.

adw.animation.Animation represents an animation on a widget. It has a target that provides a value to animate, and a state indicating whether the animation hasn't been started yet, is playing, paused or finished.

Currently there are two concrete animation types: class@TimedAnimation and class@SpringAnimation.

adw.animation.Animation will automatically skip the animation if property@Animation:widget is unmapped, or if property@Gtk.Settings:gtk-enable-animations is FALSE.

The signal@Animation::done signal can be used to perform an action after the animation ends, for example hiding a widget after animating its gtk.widget.Widget.gdouble to 0.

adw.animation.Animation will be kept alive while the animation is playing. As such, it's safe to create an animation, start it and immediately unref it: A fire-and-forget animation:

static void
animation_cb (double    value,
              MyObject *self)
{
  // Do something with @value
}

static void
my_object_animate (MyObject *self)
{
  AdwAnimationTarget *target =
    adw_callback_animation_target_new ((AdwAnimationTargetFunc) animation_cb,
                                       self, NULL);
  g_autoptr (AdwAnimation) animation =
    adw_timed_animation_new (widget, 0, 1, 250, target);

  adw_animation_play (animation);
}

If there's a chance the previous animation for the same target hasn't yet finished, the previous animation should be stopped first, or the existing adw.animation.Animation object can be reused.

Inherited Members

From ObjectG

setGObject
void setGObject(void* cObj, Flag!"Take" take)

Set the GObject of a D ObjectG wrapper.

cPtr
void* cPtr(Flag!"Dup" dup)

Get a pointer to the underlying C object.

ref_
void* ref_(void* gObj)

Calls g_object_ref() on a GObject.

unref
unref(void* gObj)

Calls g_object_unref() on a GObject.

getType
GType getType()

Get the GType of an object.

gType
GType gType [@property getter]

GObject GType property.

self
ObjectG self()

Convenience method to return this cast to a type. For use in D with statements.

getDObject
T getDObject(void* cptr, Flag!"Take" take)

Template to get the D object from a C GObject and cast it to the given D object type.

connectSignalClosure
ulong connectSignalClosure(string signalDetail, DClosure closure, Flag!"After" after)

Connect a D closure to an object signal.

setProperty
void setProperty(string propertyName, T val)

Template for setting a GObject property.

getProperty
T getProperty(string propertyName)

Template for getting a GObject property.

compatControl
size_t compatControl(size_t what, void* data)
bindProperty
gobject.binding.Binding bindProperty(string sourceProperty, gobject.object.ObjectG target, string targetProperty, gobject.types.BindingFlags flags)

Creates a binding between source_property on source and target_property on target.

bindPropertyFull
gobject.binding.Binding bindPropertyFull(string sourceProperty, gobject.object.ObjectG target, string targetProperty, gobject.types.BindingFlags flags, gobject.closure.Closure transformTo, gobject.closure.Closure transformFrom)

Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.

forceFloating
void forceFloating()

This function is intended for #GObject implementations to re-enforce a floating[floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling gobject.object.ObjectG.refSink.

freezeNotify
void freezeNotify()

Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.

getData
void* getData(string key)

Gets a named field from the objects table of associations (see gobject.object.ObjectG.setData).

getProperty
void getProperty(string propertyName, gobject.value.Value value)

Gets a property of an object.

getQdata
void* getQdata(glib.types.Quark quark)

This function gets back user data pointers stored via gobject.object.ObjectG.setQdata.

getv
void getv(string[] names, gobject.value.Value[] values)

Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.

isFloating
bool isFloating()

Checks whether object has a floating[floating-ref] reference.

notify
void notify(string propertyName)

Emits a "notify" signal for the property property_name on object.

notifyByPspec
void notifyByPspec(gobject.param_spec.ParamSpec pspec)

Emits a "notify" signal for the property specified by pspec on object.

refSink
gobject.object.ObjectG refSink()

Increase the reference count of object, and possibly remove the floating[floating-ref] reference, if object has a floating reference.

runDispose
void runDispose()

Releases all references to other objects. This can be used to break reference cycles.

setData
void setData(string key, void* data)

Each object carries around a table of associations from strings to pointers. This function lets you set an association.

setProperty
void setProperty(string propertyName, gobject.value.Value value)

Sets a property on an object.

stealData
void* stealData(string key)

Remove a specified datum from the object's data associations, without invoking the association's destroy handler.

stealQdata
void* stealQdata(glib.types.Quark quark)

This function gets back user data pointers stored via gobject.object.ObjectG.setQdata and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:

thawNotify
void thawNotify()

Reverts the effect of a previous call to gobject.object.ObjectG.freezeNotify. The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.

watchClosure
void watchClosure(gobject.closure.Closure closure)

This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling gobject.closure.Closure.invalidate on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, gobject.object.ObjectG.ref_ and gobject.object.ObjectG.unref are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.

connectNotify
ulong connectNotify(string detail, T callback, Flag!"After" after)

Connect to Notify signal.
