Detailed Description

KDE Status notifier Item protocol implementation

This class implements the Status notifier Item Dbus specification. It provides an icon similar to the classical systemtray icons, with some key differences:

the actual representation is done by the systemtray (or the app behaving like it) itself, not by this app. Since 4.5 this also includes the menu, which means you cannot use embed widgets in the menu.

there is communication between the systemtray and the icon owner, so the system tray can know if the application is in a normal or in a requesting attention state.

icons are divided in categories, so the systemtray can represent in a different way the icons from normal applications and for instance the ones about hardware status.

Whenever possible you should prefer passing icon by name rather than by pixmap because:

it is much lighter on Dbus (no need to pass all image pixels).

it makes it possible for the systemtray to load an icon of the appropriate size or to replace your icon with a systemtray specific icon which matches with the desktop theme.

some implementations of the system tray do not support passing icons by pixmap and will show a blank icon instead.

Member Enumeration Documentation

enum KStatusNotifierItem::ItemCategory

Different kinds of applications announce their type to the systemtray, so can be drawn in a different way or in a different place.

Enumerator:

ApplicationStatus	An icon for a normal application, can be seen as its taskbar entry.
Communications	This is a communication oriented application; this icon will be used for things such as the notification of a new message.
SystemServices	This is a system service, it can show itself in the system tray if it requires interaction from the user or wants to inform him about something.
Hardware	This application shows hardware status or a means to control it.
Reserved

Definition at line 110 of file kstatusnotifieritem.h.

enum KStatusNotifierItem::ItemStatus

All the possible status this icon can have, depending on the importance of the events that happens in the parent application.

Enumerator:

Passive	Nothing is happening in the application, so showing this icon is not required.
Active	The application is doing something, or it is important that the icon is always reachable from the user.
NeedsAttention	The application requests the attention of the user, for instance battery running out or a new IM message was received.

Definition at line 95 of file kstatusnotifieritem.h.

Constructor & Destructor Documentation

KStatusNotifierItem::KStatusNotifierItem ( QObject * parent = 0 ) [explicit]

Construct a new status notifier item.

Parameters:

parent the parent object for this object. If the object passed in as a parent is also a QWidget, it will be used as the main application window represented by this icon and will be shown/hidden when an activation is requested.

See also:: associatedWidget

Definition at line 101 of file kstatusnotifieritem.cpp.

KStatusNotifierItem::KStatusNotifierItem	(	const QString &	id,
		QObject *	parent = `0`
	)		`[explicit]`

Construct a new status notifier item with a unique identifier.

If your application has more than one status notifier item and the user should be able to manipulate them separately (e.g. mark them for hiding in a user interface), the id can be used to differentiate between them.

The id should remain consistent even between application restarts. Status notifier items without ids default to the application's name for the id. This id may be used, for instance, by hosts displaying status notifier items to associate configuration information with this item in a way that can persist between sessions or application restarts.

Parameters:

id	the unique id for this icon
parent	the parent object for this object. If the object passed in as a parent is also a QWidget, it will be used as the main application window represented by this icon and will be shown/hidden when an activation is requested.
