## 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).

### struct AppIndicator

    struct AppIndicator;

An 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

      “attention-icon-desc”      char *

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

Flags: Read / Write

Default value: NULL

### The `“attention-icon-name”` property

      “attention-icon-name”      char *

### The `“label”` property

      “label”                    char *

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.

### The `“label-guide”` property

      “label-guide”              char *

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.

### The `“ordering-index”` property

      “ordering-index”           guint

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.

### The `“status”` property

      “status”                   char *

Whether the indicator is shown or requests attention. Can be one of 'Passive' (the indicator should not be shown), 'Active' (the indicator should be shown in its default state), and 'Attention' (the indicator should now show it's attention icon). Defaults to 'Passive'.

### The `“title”` property

      “title”                    char *

Provides a way to refer to this application indicator in a human readable form. This is used in the Unity desktop in the HUD as the first part of the menu entries to distinguish them from the focused application's entries.
