## Includes

    #include <libedata-cal/libedata-cal.h>

## Description

This class communicates with ECalClientViews over the bus.

Calendar backends can automatically own a number of views requested by the client, this API can be used by the backend to issue notifications which will be delivered to the ECalClientView

## Functions

### e_data_cal_view_new ()

    EDataCalView *
    e_data_cal_view_new (struct _ECalBackend *backend,

Creates a new EDataCalView and exports its D-Bus interface on `connection` at `object_path` . If an error occurs while exporting, the function sets `error` and returns `NULL`.

#### Parameters

Compares the given `object` to the regular expression used for the given view.

#### Parameters

view | an EDataCalView |
object | Object to match. |

#### Returns

TRUE if the object matches the expression, FALSE if not.

### e_data_cal_view_component_matches ()

TRUE if the view has already been started, FALSE otherwise.

### e_data_cal_view_is_completed ()

    gboolean
    e_data_cal_view_is_completed (EDataCalView *view);
