Aborts the sequence change needed in the given calendar component, which means it will not require a sequence commit (via #e_cal_component_commit_sequence) even if the changes done require a sequence increment.
Adds an alarm subcomponent to a calendar component. You should have created
the alarm by using e_cal_component_alarm_new(); it is invalid to use a
#ECalComponentAlarm structure that came from e_cal_component_get_alarm(). After
adding the alarm, the alarm structure is no longer valid because the
internal structures may change and you should get rid of it by using
e_cal_component_alarm_free().
An alarm.
Creates a binding between source_property on source and target_property
on target.
Whenever the source_property is changed the target_property is
updated using the same value. For instance:
g_object_bind_property (action, "active", widget, "sensitive", 0);
Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.
If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well.
The binding will automatically be removed when either the source or the
target instances are finalized. To remove the binding without affecting the
source and the target you can just call g_object_unref() on the returned
#GBinding instance.
Removing the binding by calling g_object_unref() on it must only be done if
the binding, source and target are only used from a single thread and it
is clear that both source and target outlive the binding. Especially it
is not safe to rely on this if the binding, source or target can be
finalized from different threads. Keep another reference to the binding and
use g_binding_unbind() instead to be on the safe side.
A #GObject can have multiple bindings.

Creates a binding between source_property on source and target_property

Creates a new calendar component object by copying the information from another one.
Increments the sequence number property in a calendar component object if it needs it. This needs to be done when any of a number of properties listed in RFC 2445 change values, such as the start and end dates of a component.
This function must be called before calling e_cal_component_get_as_string() to ensure that the component is fully consistent.
Checks if the DTSTART and DTEND properties of the 2 components match. Note that the events may have different recurrence properties which are not taken into account here.
A calendar component object.
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 g_object_ref_sink().
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.
This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.
Builds a list of the unique identifiers of the alarm subcomponents inside a calendar component.
Gets the iCalendar string representation of a calendar component. You should call e_cal_component_commit_sequence() before this function to ensure that the component's sequence number is consistent with the state of the object.
Queries the attachment properties of the calendar component object. When done,
the attachment_list should be freed by calling g_slist_free().
Queries the attendee properties of the calendar component object
Queries the categories of the given calendar component. The categories
are returned in the categories argument, which, on success, will contain
a comma-separated list of all categories set in the component.
Return holder for the categories.
Queries the list of categories of a calendar component object. Each element in the returned categ_list is a string with the corresponding category.
Queries the classification of a calendar component object. If the classification property is not set on this component, this function returns #E_CAL_COMPONENT_CLASS_NONE.
Return value for the classification.
Queries the comments of a calendar component object. The comment property can appear several times inside a calendar component, and so a list of #ECalComponentText is returned.
Queries the date at which a calendar compoment object was completed.
Return value for the completion date. This should be freed using the e_cal_component_free_icaltimetype() function.
Queries the contact of a calendar component object. The contact property can appear several times inside a calendar component, and so a list of #ECalComponentText is returned.
Queries the date in which a calendar component object was created in the calendar store.
Return value for the creation date. This should be freed using the e_cal_component_free_icaltimetype() function.
Gets a named field from the objects table of associations (see g_object_set_data()).
name of the key for that association
Queries the description of a calendar component object. Journal components may have more than one description, and as such this function returns a list of #ECalComponentText structures. All other types of components can have at most one description.
Queries the date/time end of a calendar component object.
Return value for the date/time end. This should be freed with the e_cal_component_free_datetime() function.
Queries the date/timestamp property of a calendar component object, which is the last time at which the object was modified by a calendar user agent.
A value for the date/timestamp.
Queries the date/time start of a calendar component object.
Return value for the date/time start. This should be freed with the e_cal_component_free_datetime() function.
Queries the due date/time of a calendar component object.
Return value for the due date/time. This should be freed with the e_cal_component_free_datetime() function.
Queries the list of exception date properties in a calendar component object.
Gets the geographic position property of a calendar component object.
Return value for the geographic position property. This should be freed using the e_cal_component_free_geo() function.
Queries the time at which a calendar component object was last modified in the calendar store.
Return value for the last modified time value.
Queries the location property of a calendar component object.
Return value for the location.
Get the number of attachments to this calendar component object.
Queries the organizer property of a calendar component object
A value for the organizer
Queries the percent-complete property of a calendar component object.
Return value for the percent-complete property. This should be freed using the e_cal_component_free_percent() function.
Queries the priority property of a calendar component object.
Return value for the priority property. This should be freed using the e_cal_component_free_priority() function.
Gets a property of an object.
The value can be:
In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling g_value_unset().
Note that g_object_get_property() is really intended for language bindings, g_object_get() is much more convenient for C programming.
the name of the property to get
return location for the property value

Checks whether the given calendar component object has simple recurrence rules or more complicated ones.
Checks whether object has a [floating][floating-ref] reference.
Checks whether a calendar component object is an instance of a recurring event.
Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.
Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.
the name of a property installed on the class of object.
Emits a "notify" signal for the property specified by pspec on object.
This function omits the property name lookup, hence it is faster than g_object_notify().
One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with g_object_class_install_property() inside a static array, e.g.:
enum
{
PROP_0,
PROP_FOO,
PROP_LAST
};
static GParamSpec *properties[PROP_LAST];
static void
my_object_class_init (MyObjectClass *klass)
{
properties[PROP_FOO] = g_param_spec_int ("foo", "Foo", "The foo",
0, 100,
50,
G_PARAM_READWRITE);
g_object_class_install_property (gobject_class,
PROP_FOO,
properties[PROP_FOO]);
}
and then notify a change on the "foo" property with:
g_object_notify_by_pspec (self, properties[PROP_FOO]);
the #GParamSpec of a property installed on the class of object.
Increase the reference count of object, and possibly remove the
[floating][floating-ref] reference, if object has a floating reference.
In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.
Since GLib 2.56, the type of object will be propagated to the return type
under the same conditions as for g_object_ref().
Removes an alarm subcomponent from a calendar component. If the alarm that
corresponds to the specified auid had been fetched with
e_cal_component_get_alarm(), then those alarm structures will be invalid; you
should get rid of them with e_cal_component_alarm_free() before using this
function.

Sets the date in which a calendar component object is created in the calendar store. This should only be used inside a calendar store application, i.e. not by calendar user agents.
Value for the creation date.
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
If the object already had an association with that name, the old association will be destroyed.
Internally, the key is converted to a #GQuark using g_quark_from_string().
This means a copy of key is kept permanently (even after object has been
finalized) — so it is recommended to only use a small, bounded set of values
for key in your program, to avoid the #GQuark storage growing unbounded.

name of the key
This function gets back user data pointers stored via
g_object_set_qdata() 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:
void
object_add_to_user_list (GObject *object,
const gchar *new_string)
{
// the quark, naming the object data
GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
// retrieve the old string list
GList *list = g_object_steal_qdata (object, quark_string_list);
// prepend new string
list = g_list_prepend (list, g_strdup (new_string));
// this changed 'list', so we need to set it again
g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
}
static void
free_string_list (gpointer data)
{
GList *node, *list = data;
for (node = list; node; node = node->next)
g_free (node->data);
g_list_free (list);
}
Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().
A #GQuark, naming the user data pointer
Strips all error messages from the calendar component. Those error messages are added to the iCalendar string representation whenever an invalid is used for one of its fields.
Reverts the effect of a previous call to
g_object_freeze_notify(). The freeze count is decreased on object
and when it reaches zero, queued "notify" signals are emitted.
Duplicate notifications for each property are squashed so that at most one #GObject::notify signal is emitted for each property, in the reverse order in which they have been queued.
It is an error to call this function when the freeze count is zero.
Decreases the reference count of object. When its reference count
drops to 0, the object is finalized (i.e. its memory is freed).
If the pointer to the #GObject may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to %NULL rather than retain a dangling pointer to a potentially invalid #GObject instance. Use g_clear_object() for this.
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 g_closure_invalidate() on
it, in order to prevent invocations of the closure with a finalized
(nonexisting) object. Also, g_object_ref() and g_object_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.

name of a property to look up.
Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.
This function is meant to be called from the interface's default
vtable initialization function (the class_init member of
#GTypeInfo.) It must not be called after after class_init has
been called for any object types implementing this interface.
If pspec is a floating reference, it will be consumed.
