## Includes

    #include <libebook-contacts/libebook-contacts.h>

## Description

This is the main user facing interface used for representing an event or other component in a given calendar.

## Functions

### e_cal_component_gen_uid ()

    gchar *
    e_cal_component_gen_uid (void);

Generates a unique identifier suitable for calendar components.

#### Returns

A unique identifier string. Every time this function is called a different string is returned.

### e_cal_component_new ()

    ECalComponent *
    e_cal_component_new (void);

Creates a new empty calendar component object. Once created, you should set it from an existing icalcomponent structure by using `e_cal_component_set_icalcomponent()` or with a new empty component type by using `e_cal_component_set_new_vtype()`.

#### Returns

A newly-created calendar component object.

### e_cal_component_new_from_string ()

    ECalComponent *
    e_cal_component_new_from_string (const gchar *calobj);

Creates a new calendar component object from the given iCalendar string.

#### Parameters

calobj | A string representation of an iCalendar component. |

#### Returns

A calendar component representing the given iCalendar string on success, NULL if there was an error.

### e_cal_component_new_from_icalcomponent ()

    ECalComponent *
    e_cal_component_new_from_icalcomponent
                                   (icalcomponent *icalcomp);

Creates a new ECalComponent which will has set `icalcomp` as an inner icalcomponent. The newly created ECalComponent takes ownership of the `icalcomp` , and if the call to `e_cal_component_set_icalcomponent()` fails, then `icalcomp` is freed.

#### Parameters

icalcomp | An icalcomponent to use |

#### Returns

An ECalComponet with `icalcomp` assigned on success, NULL if the `icalcomp` cannot be assigned to ECalComponent.

Since 3.4

### e_cal_component_clone ()

    ECalComponent *
    e_cal_component_clone (ECalComponent *comp);

Creates a new calendar component object by copying the information from another one.

#### Parameters

comp | A calendar component object. |

#### Returns

A newly-created calendar component with the same values as the original one.

[transfer full]

### e_cal_component_set_new_vtype ()

    void
    e_cal_component_set_new_vtype (ECalComponent *comp,
                                   ECalComponentVType type);

Clears any existing component data from a calendar component object and creates a new icalcomponent of the specified type for it. The only property that will be set in the new component will be its unique identifier.

#### Parameters

comp | A calendar component object. |
type | Type of calendar component to create. |

### e_cal_component_get_icalcomponent ()

    icalcomponent *
    e_cal_component_get_icalcomponent (ECalComponent *comp);

Queries the icalcomponent structure that a calendar component object is wrapping.

#### Parameters

comp | A calendar component object. |

#### Returns

An icalcomponent structure, or NULL if the `comp` has no icalcomponent set to it.

### e_cal_component_set_icalcomponent ()

    gboolean
    e_cal_component_set_icalcomponent (ECalComponent *comp,
                                       icalcomponent *icalcomp);

Sets the contents of a calendar component object from an icalcomponent structure. If the `comp` already had an icalcomponent set into it, it will will be freed automatically if the icalcomponent does not have a parent component itself.

Supported component types are VEVENT, VTODO, VJOURNAL, VFREEBUSY, and VTIMEZONE.

#### Parameters

comp | A calendar component object. |
icalcomp | An icalcomponent. | [type long]

#### Returns

TRUE on success, FALSE if `icalcomp` is an unsupported component type.

### e_cal_component_rescan ()

    void
    e_cal_component_rescan (ECalComponent *comp);

#### Parameters

comp | A calendar component object. |

### e_cal_component_strip_errors ()

    void
    e_cal_component_strip_errors (ECalComponent *comp);

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.

#### Parameters

comp | A calendar component object. |

### e_cal_component_get_vtype ()

    ECalComponentVType
    e_cal_component_get_vtype (ECalComponent *comp);

Queries the type of a calendar component object.

#### Parameters

comp | A calendar component object. |

#### Returns

The type of the component, as defined by RFC 2445.

### e_cal_component_get_as_string ()

    gchar *
    e_cal_component_get_as_string (ECalComponent *comp);

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.

#### Parameters

comp | A calendar component. |

#### Returns

String representation of the calendar component according to RFC 2445.

### e_cal_component_commit_sequence ()

    void
    e_cal_component_commit_sequence (ECalComponent *comp);

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.

#### Parameters

comp | A calendar component object. |

### e_cal_component_abort_sequence ()

    void
    e_cal_component_abort_sequence (ECalComponent *comp);

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.

### e_cal_component_free_text_list ()

    void
    e_cal_component_free_text_list (GSList *text_list);

Frees a list of ECalComponentText structures. This function should only be used to free lists of text values as returned by the other getter functions of ECalComponent.

TRUE if the component has any alarms.

### e_cal_component_add_alarm ()

    e_cal_component_add_alarm (ECalComponent *comp,
                               ECalComponentAlarm *alarm);

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()`.

#### Parameters

comp | A calendar component. |
alarm | An alarm. |

### e_cal_component_remove_alarm ()

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.

#### Parameters

comp | A calendar component. |
auid | UID of the alarm to remove. |

### e_cal_component_remove_all_alarms ()

    void
    e_cal_component_remove_all_alarms (ECalComponent *comp);
