Detailed Description

KNotification is the main class for creating notifications.

Definition at line 32 of file knotification.h.

Member Typedef Documentation

◆ Context

Sometimes the user may want different notifications for the same event, depending the source of the event.

Example, you want to be notified for mails that arrive in your folder "personal inbox" but not for those in "spam" folder

A notification context is a pair of two strings. The first string is a key from what the context is. example "group" or "filter" (not translated). The second is the id of the context. In our example, the group id or the filter id in the applications. These strings are the ones present in the config file, and are in theory not shown in the user interface.

The order of contexts in the list is is important, the most important context should be placed first. They are processed in that order when the notification occurs.

event

Definition at line 114 of file knotification.h.

◆ NotificationFlags

Stores a combination of NotificationFlag values.

Definition at line 176 of file knotification.h.

Member Enumeration Documentation

◆ NotificationFlag

See also
NotificationFlags
Enumerator
RaiseWidgetOnActivation 

When the notification is activated, raise the notification's widget.

This will change the desktop, raise the window, and switch to the tab.

Todo:
doesn't work yet
CloseOnTimeout 

The notification will be automatically closed after a timeout.

(this is the default)

Persistent 

The notification will NOT be automatically closed after a timeout.

You will have to track the notification, and close it with the close function manually when the event is done, otherwise there will be a memory leak

CloseWhenWidgetActivated 

The notification will be automatically closed if the widget() becomes activated.

If the widget is already activated when the notification occurs, the notification will be closed after a small timeout.

This only works if the widget is the toplevel widget

Todo:
make it work with tabulated widget
LoopSound 

The audio plugin will loop the sound until the notification is closed.

SkipGrouping 

Sends a hint to Plasma to skip grouping for this notification.

Since
5.18
DefaultEvent 

The event is a standard kde event, and not an event of the application

Definition at line 120 of file knotification.h.

◆ StandardEvent

default events you can use in the event function

Definition at line 182 of file knotification.h.

◆ Urgency

The urgency of a notification.

Since
5.58

setUrgency

Definition at line 195 of file knotification.h.

Property Documentation

◆ actions

QStringList KNotification::actions
readwrite

Set the list of actions shown in the popup.

The strings passed in that QStringList will be used as labels for those actions, so ideally they should be wrapped in i18n() or tr() calls. In Plasma workspace, these will be shown as buttons inside the notification popup.

The visual representation of actions however depends on the notification server

Parameters
actionsList of strings used as action labels
Since
5.88

Definition at line 64 of file knotification.h.

◆ autoDelete

bool KNotification::autoDelete
readwrite

Sets whether this notification object will be automatically deleted after closing.

This is on by default for C++, and off by default for QML.

Since
5.88 @seince 5.88

Definition at line 89 of file knotification.h.

◆ componentName

QString KNotification::componentName
readwrite

The componentData is used to determine the location of the config file.

If no componentName is set, the app name is used by default

Parameters
componentNamethe new component name
Since
5.88

Definition at line 74 of file knotification.h.

◆ defaultAction

QString KNotification::defaultAction
readwrite

Set a default action that will be triggered when the notification is activated (typically, by clicking on the notification popup).

The default action should raise a window belonging to the application that sent it.

The string will be used as a label for the action, so ideally it should be wrapped in i18n() or tr() calls.

The visual representation of actions depends on the notification server. In Plasma and Gnome desktops, the actions are performed by clicking on the notification popup, and the label is not presented to the user.

Parameters
actionLabel of the default action. The label might or might not be displayed to the user by the notification server, depending on the implementation. Passing an empty string disables the default action.
Since
5.31
5.88

Definition at line 59 of file knotification.h.

◆ eventId

QString KNotification::eventId
readwrite

Set the event id, if not already passed to the constructor.

Since
5.88
5.88

Definition at line 39 of file knotification.h.

◆ flags

KNotification::NotificationFlags KNotification::flags
readwrite

Set the notification flags.

These must be set before calling sendEvent()

Since
5.88

Definition at line 69 of file knotification.h.

◆ iconName

QString KNotification::iconName
readwrite

Set the icon that will be shown in the popup.

Parameters
iconthe icon
Since
5.4
5.88

Definition at line 54 of file knotification.h.

◆ text

QString KNotification::text
readwrite

Set the notification text that will appear in the popup.

In Plasma workspace, the text is shown in a QML label which uses Text.StyledText, ie. it supports a small subset of HTML entities (mostly just formatting tags)

If the notifications server does not advertise "body-markup" capability, all HTML tags are stripped before sending it to the server

Parameters
textThe text to display in the notification popup
Since
5.88

Definition at line 49 of file knotification.h.

◆ title

QString KNotification::title
readwrite

Set the title of the notification popup.

If no title is set, the application name will be used.

Parameters
titleThe title of the notification
Since
4.3
5.88

Definition at line 44 of file knotification.h.

◆ urgency

KNotification::Urgency KNotification::urgency
readwrite

Sets the urgency of the notification.

This defines the importance of the notification. For example, a track change in a media player would be a low urgency. "You have new mail" would be normal urgency. "Your battery level is low" would be a critical urgency.

Use critical notifications with care as they might be shown even when giving a presentation or when notifications are turned off.

Parameters
urgencyThe urgency.
Since

5.88

Definition at line 84 of file knotification.h.

◆ urls

QList< QUrl > KNotification::urls

Note
This feature might not be supported by the user's notification service
Parameters
urlsA list of URLs

Definition at line 503 of file knotification.cpp.

◆ setActions()

void KNotification::setActions ( const QStringList actions)

Set the list of actions shown in the popup.

The strings passed in that QStringList will be used as labels for those actions, so ideally they should be wrapped in i18n() or tr() calls. In Plasma workspace, these will be shown as buttons inside the notification popup.

The visual representation of actions however depends on the notification server

Parameters
actionsList of strings used as action labels

Definition at line 191 of file knotification.cpp.

◆ setAutoDelete()

void KNotification::setAutoDelete ( bool  autoDelete)

Parameters
componentNamethe new component name

Definition at line 286 of file knotification.cpp.

◆ setContexts()

void KNotification::setContexts ( const ContextList contexts)

set the list of contexts, see KNotification::Context

The list of contexts must be set before calling sendEvent;

Definition at line 247 of file knotification.cpp.

◆ setDefaultAction()

void KNotification::setDefaultAction ( const QString defaultAction)

Set a default action that will be triggered when the notification is activated (typically, by clicking on the notification popup).

The default action should raise a window belonging to the application that sent it.

The string will be used as a label for the action, so ideally it should be wrapped in i18n() or tr() calls.

The visual representation of actions depends on the notification server. In Plasma and Gnome desktops, the actions are performed by clicking on the notification popup, and the label is not presented to the user.

Parameters
actionLabel of the default action. The label might or might not be displayed to the user by the notification server, depending on the implementation. Passing an empty string disables the default action.
