## Description

Contains functions to work with the ECalComponentPropertyBag structure.

## Functions

### e_cal_component_property_bag_new ()

    ECalComponentPropertyBag *
    e_cal_component_property_bag_new (void);

Creates a new ECalComponentPropertyBag. Free the structure with `e_cal_component_property_bag_free()`, when no longer needed.

#### Returns

a newly allocated ECalComponentPropertyBag.

[transfer full]

Since: 3.34

### e_cal_component_property_bag_new_from_component ()

    ECalComponentPropertyBag *
    e_cal_component_property_bag_new_from_component
                                   (const ICalComponent *component,
                                    ECalComponentPropertyBagFilterFunc func,
                                    gpointer user_data);

Creates a new ECalComponentPropertyBag, filled with properties from the `component` , for which the `func` returned `TRUE`. When the `func` is `NULL`, all the properties are included.

Free the structure with `e_cal_component_property_bag_free()`, when no longer needed.

#### Parameters

component | an ICalComponent containing the properties to fill the bag with |
func | an optional `ECalComponentPropertyBagFilterFunc` callback. | [nullable][scope call]
user_data | user data for the `func` . | [closure func]

#### Returns

a newly allocated ECalComponentPropertyBag.

[transfer full]

Since: 3.34

### e_cal_component_property_bag_copy ()

    ECalComponentPropertyBag *
    e_cal_component_property_bag_copy (const ECalComponentPropertyBag *bag);

Returns a newly allocated copy of `bag` , which should be freed with `e_cal_component_property_bag_free()`, when no longer needed.

#### Parameters

bag | an ECalComponentPropertyBag. | [not nullable]

#### Returns

a newly allocated copy of `bag` .

[transfer full]

Since: 3.34

### e_cal_component_property_bag_free ()

    void
    e_cal_component_property_bag_free (gpointer bag);

Free `bag` , previously created by `e_cal_component_property_bag_new()`, `e_cal_component_property_bag_new_from_component()` or `e_cal_component_property_bag_copy()`. The function does nothing, if `bag` is `NULL`.

[skip]
