# Gtk::StatusIcon Class Reference

Inheritance diagram for Gtk::StatusIcon:

[legend]

List of all members.

## Detailed Description

The "system tray" or notification area is normally used for transient icons that indicate some special state.

For example, a system tray icon might appear to tell the user that they have new mail, or have an incoming instant message, or something along those lines. The basic idea is that creating an icon in the notification area is less annoying than popping up a dialog.

A StatusIcon object can be used to display an icon in a "system tray". The icon can have a tooltip, and the user can interact with it by activating it or popping up a context menu. Critical information should not solely be displayed in a StatusIcon, since it may not be visible (e.g. when the user doesn't have a notification area on his panel). This can be checked with is_embedded().

On X11, the implementation follows the freedesktop.org "System Tray" specification. Implementations of the "tray" side of this specification can be found e.g. in the GNOME and KDE panel applications.

This function is not intended for other use cases which are more likely to be met by one of the non-X11 specific methods, such as position_menu().

Applications can use this function to display context-sensitive menus.

This is equivalent to the gtk_status_icon_position_menu() helper callback in GTK+, which can be provided to gtk_menu_popup().

See Gtk::Menu::popup() for more details.

Parameters:

  | menu | The menu to popup for the status icon.
  | button | The mouse button which was pressed to initiate the event.
  | activate_time | The time at which the activation event occurred.
