## Description

GWeatherInfo provides a handy way to access weather conditions and forecasts from a GWeatherLocation, aggregating multiple different web services.

It includes also astronomical data such as sunrise times and moon phases.

## Details

### enum GWeatherForecastType

    typedef enum {
     /*< underscore_name=gweather_forecast_type >*/
        GWEATHER_FORECAST_STATE,
        GWEATHER_FORECAST_ZONE,
        GWEATHER_FORECAST_LIST
    } GWeatherForecastType;

`GWEATHER_FORECAST_STATE` |
`GWEATHER_FORECAST_ZONE` |
`GWEATHER_FORECAST_LIST` |

### gweather_info_new ()

    GWeatherInfo *      gweather_info_new                   (GWeatherLocation *location,
                                                             GWeatherForecastType forecast_type);

Builds a new GWeatherInfo that will provide weather information about `location`. The returned info will not be ready until the "updated" signal is emitted.

`location` : | the desidered GWeatherLocation (NULL for default). [allow-none]
`forecast_type` : | the type of forecast requested
Returns : | a new GWeatherInfo. [transfer full]

### gweather_info_new_for_world ()

    GWeatherInfo *      gweather_info_new_for_world         (GWeatherLocation *world,

Similar to `gweather_info_new()`, but also has a `world` parameter, that allow controlling the hierarchy of GWeatherLocation to which `location` (or the default one taken from GSettings) belongs.

`world` : | a GWeatherLocation representing the whole world
`location` : | the desidered GWeatherLocation (NULL for default). [allow-none]
`forecast_type` : | the type of forecast requested
Returns : | a new GWeatherInfo. [transfer full]

Changes `info` to report weather for `location`.

`info` : | a GWeatherInfo
`location` : | a location for which weather is desired. [allow-none]

### gweather_info_get_forecast_list ()

    GSList *            gweather_info_get_forecast_list     (GWeatherInfo *info);

`info` : | a GWeatherInfo
Returns : | list of GWeatherInfo* objects for the forecast. The list is owned by the 'info' object thus is alive as long as the 'info'. This list is filled only when requested with type FORECAST_LIST and if available for given location. The 'update' property is the date/time when the forecast info is used for. [transfer none][element-type GWeather.Info]

        GWEATHER_PROVIDER_ALL = 31
    } GWeatherProvider;

`GWEATHER_PROVIDER_NONE` | no provider, no weather information available
`GWEATHER_PROVIDER_METAR` | METAR office, providing current conditions worldwide
`GWEATHER_PROVIDER_IWIN` | US weather office, providing 7 days of forecast
`GWEATHER_PROVIDER_YAHOO` | Yahoo Weather Service, worldwide but non commercial only
