◆ __createEntry()

Q_INVOKABLE KNSCore::Entry Engine::__createEntry	(	const QString &	providerId,
		const QString &	entryId )

inline

Definition at line 151 of file quickengine.h.

◆ adoptEntry()

void Engine::adoptEntry ( const KNSCore::Entry & entry )

Adopt an entry using the adoption command.

This will also take care of displaying error messages

Parameters

entry Entry that should be adopted

See also: signalErrorCode; signalEntryEvent

Since: 5.77

Definition at line 499 of file quickengine.cpp.

◆ busyMessage()

◆ busyState()

Engine::BusyState Engine::busyState ( ) const

Definition at line 195 of file quickengine.cpp.

◆ busyStateChanged()

Q_SIGNAL void Engine::busyStateChanged ( )

Signal gets emitted when the busy state changes.

Since: 5.74

◆ entryEvent

void Engine::entryEvent	(	const KNSCore::Entry &	entry,
		KNSCore::Entry::EntryEvent	event )

signal

This is fired for events related directly to a single Entry instance The intermediate states Updating and Installing are not forwarded.

In case you need those you have to listen to the signals of the KNSCore::Engine instance of the engine property.

As an example, if you need to know when the status of an entry changes, you might write:

function onEntryEvent(entry, event) {
    if (event == NewStuff.Engine.StatusChangedEvent) {
        myModel.ghnsEntryChanged(entry);
    }
}

nb: The above example is also how one would port a handler for the old changedEntries signal

See also: Entry::EntryEvent for details on which specific event is being notified

◆ errorCode

void Engine::errorCode	(	KNSCore::ErrorCode::ErrorCode	errorCode,
		const QString &	message,
		const QVariant &	metadata )

signal

Fires in the case of any critical or serious errors, such as network or API problems.

This forwards the signal from KNSCore::Engine::signalErrorCode, but with QML friendly enumerations.

Parameters

errorCode	Represents the specific type of error which has occurred
message	A human-readable message which can be shown to the end user
metadata	Any additional data which might be helpful to further work out the details of the error (see KNSCore::Entry::ErrorCode for the metadata details)
