## Description

An application indicator is a way for an application to put a menu into the panel on the user's screen. This allows the user to interact with the application even though it might not be visible to the user at the time. In most cases this is not a good solution as there are other ways to inform the user. It should only be use if persistence is a desired feature for the user (not for your marketing purpose of having your logo in the panel).

### enum AppIndicatorCategory

    typedef enum { /*< prefix=APP_INDICATOR_CATEGORY >*/
    	APP_INDICATOR_CATEGORY_APPLICATION_STATUS, /*< nick=ApplicationStatus >*/
    	APP_INDICATOR_CATEGORY_COMMUNICATIONS, /*< nick=Communications >*/
    	APP_INDICATOR_CATEGORY_SYSTEM_SERVICES, /*< nick=SystemServices >*/
    	APP_INDICATOR_CATEGORY_HARDWARE, /*< nick=Hardware >*/
    	APP_INDICATOR_CATEGORY_OTHER /*< nick=Other >*/
    } AppIndicatorCategory;

The category provides grouping for the indicators so that users can find indicators that are similar together.

`APP_INDICATOR_CATEGORY_APPLICATION_STATUS`

  The indicator is used to display the status of the application.

`APP_INDICATOR_CATEGORY_COMMUNICATIONS`

  The application is used for communication with other people.

`APP_INDICATOR_CATEGORY_SYSTEM_SERVICES`

  A system indicator relating to something in the user's system.

`APP_INDICATOR_CATEGORY_HARDWARE`

  An indicator relating to the user's hardware.

`APP_INDICATOR_CATEGORY_OTHER`

  Something not defined in this enum, please don't use unless you really need it.

AppIndicatorCategory

### enum AppIndicatorStatus

    typedef enum { /*< prefix=APP_INDICATOR_STATUS >*/
    	APP_INDICATOR_STATUS_PASSIVE, /*< nick=Passive >*/
    	APP_INDICATOR_STATUS_ACTIVE, /*< nick=Active >*/
    	APP_INDICATOR_STATUS_ATTENTION /*< nick=NeedsAttention >*/
    } AppIndicatorStatus;

These are the states that the indicator can be on in the user's panel. The indicator by default starts in the state APP_INDICATOR_STATUS_PASSIVE and can be shown by setting it to APP_INDICATOR_STATUS_ACTIVE.

`APP_INDICATOR_STATUS_PASSIVE`

  The indicator should not be shown to the user.

`APP_INDICATOR_STATUS_ACTIVE`

  The indicator should be shown in it's default state.

`APP_INDICATOR_STATUS_ATTENTION`

  The indicator should show it's attention icon.

AppIndicatorStatus

### AppIndicatorPrivate

    typedef struct _AppIndicatorPrivate AppIndicatorPrivate;

All of the private data in an instance of a application indicator.

AppIndicatorPrivate

### AppIndicator

    typedef struct _AppIndicator AppIndicator;

A application indicator represents the values that are needed to show a unique status in the panel for an application. In general, applications should try to fit in the other indicators that are available on the panel before using this. But, sometimes it is necissary.

## Property Details

### The `"attention-icon-name"` property

      "attention-icon-name"      gchar*                : Read / Write

If the indicator sets it's status to `APP_INDICATOR_STATUS_ATTENTION` then this icon is shown.

Default value: NULL

AppIndicator:attention-icon-name

### The `"category"` property

      "category"                 gchar*                : Read / Write / Construct Only

The type of indicator that this represents. Please don't use 'Other'. Defaults to 'ApplicationStatus'.

Default value: NULL

AppIndicator:category

### The `"connected"` property

      "connected"                gboolean              : Read

Pretty simple, `TRUE` if we have a reasonable expectation of being displayed through this object. You should hide your TrayIcon if so.

Default value: FALSE

AppIndicator:connected

### The `"icon-name"` property

      "icon-name"                gchar*                : Read / Write / Construct

The name of the regular icon that is shown for the indicator.

Default value: NULL

AppIndicator:icon-name

### The `"icon-theme-path"` property

      "icon-theme-path"          gchar*                : Read / Write / Construct

An additional place to look for icon names that may be installed by the application.

Default value: NULL

AppIndicator:icon-theme-path

### The `"id"` property

      "id"                       gchar*                : Read / Write / Construct Only

The ID for this indicator, which should be unique, but used consistently by this program and its indicator.

Default value: NULL

AppIndicator:id

### The `"label"` property

      "label"                    gchar*                : Read / Write

A label that can be shown next to the string in the application indicator. The label will not be shown unless there is an icon as well. The label is useful for numerical and other frequently updated information. In general, it shouldn't be shown unless a user requests it as it can take up a significant amount of space on the user's panel. This may not be shown in all visualizations.

Default value: NULL

AppIndicator:label

### The `"label-guide"` property

      "label-guide"              gchar*                : Read / Write

An optional string to provide guidance to the panel on how big the "label" string could get. If this is set correctly then the panel should never 'jiggle' as the string adjusts through out the range of options. For instance, if you were providing a percentage like "54% thrust" in "label" you'd want to set this string to "100% thrust" to ensure space when Scotty can get you enough power.

Default value: NULL

AppIndicator:label-guide

### The `"menu"` property

      "menu"                     DBusGObjectPath*      : Read

A method for getting the menu path as a string for DBus.

AppIndicator:menu

### The `"ordering-index"` property

      "ordering-index"           guint                 : Read / Write

The ordering index is an odd parameter, and if you think you don't need it you're probably right. In general, the application indicator try to place the applications in a recreatable place taking into account which category they're in to try and group them. But, there are some cases where you'd want to ensure indicators are next to each other. To do that you can override the generated ordering index and replace it with a new one. Again, you probably don't want to be doing this, but in case you do, this is the way.

Default value: 0

AppIndicator:ordering-index

### The `"status"` property

      "status"                   gchar*                : Read / Write

Whether the indicator is shown or requests attention. Defaults to 'Passive'.

Default value: NULL

Default value: NULL

AppIndicator:x-ayatana-label-guide

      "x-ayatana-ordering-index" guint                 : Read / Write

Default value: 0

AppIndicator:x-ayatana-ordering-index
