/*! \qmltype IntentHandler
\inqmlmodule QtApplicationManager.Application
\ingroup common-instantiatable
\brief A handler for intent requests received by applications.
Any application that has intents listed in its manifest file needs to have a corresponding
IntentHandler instance that is actually able to handle incoming requests. This class gives
you the flexibility to handle multiple, different intent ids via a single IntentHandler
instance or have a dedicated IntentHandler instance for every intent id (or any combination of
those).
Here is a fairly standard way to handle an incoming intent request and send out a result or
error message:
\qml
Image {
id: viewer
}
IntentHandler {
intentIds: [ "show-image" ]
onRequestReceived: {
var url = request.parameters["url"]
if (!url.startsWith("file://")) {
request.sendErrorReply("Only file:// urls are supported")
} else {
viewer.source = url
request.sendReply({ "status": source.status })
}
}
}
\endqml
*/
/*! \qmlproperty list<string> IntentHandler::intentIds
Every handler needs to register at least one unique intent id that it will handle. Having
multiple IntentHandlers that are registering the same intent id is not possible.
\note Any changes to this property after component completion will have no effect. This
restriction will likely be removed in a future update.
*/
/*! \qmlsignal IntentHandler::requestReceived(IntentRequest request)
This signal will be emitted once for every incoming intent \a request that this handler was
registered for via its intentIds property.
Handling the request can be done synchronously or asynchronously. As soon as your handler has
either produced a result or detected an error condition, it should call either
IntentClientRequest::sendReply() or IntentClientRequest::sendErrorReply respectively to send a
reply back to the requesting party.
Only the first call to one of these functions will have any effect. Any further invocations
will be ignored.
