Signals

void	requestFailed(QOhosElementName elementName, QString message)
void	requestSucceeded(QOhosElementName elementName, QString message)

Detailed Description

QOhosStartRequest adapts the StartOptions completionHandler into Qt signals. The requestSucceeded() and requestFailed() signals correspond to onRequestSuccess and onRequestFailure callbacks from the platform completion handler.

Create an instance using createStartRequest().

See Completion Handler.

 auto options = QtOhosExtras::createStartOptions();
 auto request = QtOhosExtras::createStartRequest(*options);

 QObject::connect(
     request.get(), &QtOhosExtras::QOhosStartRequest::requestSucceeded,
     [](const QtOhosExtras::QOhosElementName &elementName, const QString &message) {
         qDebug() << "started" << elementName.abilityName << message;
     });
 QObject::connect(
     request.get(), &QtOhosExtras::QOhosStartRequest::requestFailed,
     [](const QtOhosExtras::QOhosElementName &elementName, const QString &message) {
         qWarning() << "failed to start" << elementName.abilityName << message;
     });

 QtOhosExtras::QOhosWant want;
 want.bundleName = QStringLiteral("com.example.target");
 want.abilityName = QStringLiteral("EntryAbility");
 QtOhosExtras::startAbility(want, *request);

Member Function Documentation

`[signal]` void QOhosStartRequest::requestFailed(QOhosElementName elementName, QString message)

Signal emitted when the start request fails. It corresponds to the onRequestFailure callback of the platform completion handler. The elementName identifies the intended target ability; it may be left empty when the target cannot be resolved, for example when an implicit start fails. The message carries the failure information provided by the system as a JSON string. See onRequestFailure.

See also requestSucceeded().

`[signal]` void QOhosStartRequest::requestSucceeded(QOhosElementName elementName, QString message)

Signal emitted when the start request completes successfully. It corresponds to the onRequestSuccess callback of the platform completion handler. The elementName identifies the started ability and message carries additional information provided by the system. See onRequestSuccess.
