Share Data Receiver Example

Demonstrates receiving Share Kit records delivered to the application through a want.

The window is a log view. At startup the example reads QOhosAppContext::getAppLaunchWantInfo() and calls QOhosWantInfo::tryGetSharedRecordsFromShareKit(), printing the MIME type, content and file path of every record, or a note that no shared data arrived. The same handling is connected to QOhosAbilityContext::newWantInfoReceived() so shares that arrive while the application is already running are logged as well.

Reading shared records from the launch want:

     auto wantInfo = QtOhosExtras::QOhosAppContext::getAppLaunchWantInfo();
     auto sharedDataRecords = wantInfo->tryGetSharedRecordsFromShareKit();

Handling wants that arrive while the application is running:

     auto abilityContext = QtOhosExtras::QOhosAbilityContext::instance();
     QObject::connect(
         abilityContext,
         &QtOhosExtras::QOhosAbilityContext::newWantInfoReceived,
         [&](auto wantInfo) {
             auto sharedDataRecords = wantInfo->tryGetSharedRecordsFromShareKit();
             window.appendText(
                 !sharedDataRecords.isNull()
                     ? QStringLiteral("[On New Want] received Shared Data records:\n%1")
                         .arg(recordsToString(*sharedDataRecords))
                     : QStringLiteral("[On New Want] there is no Shared Data."));
         });

Note: Both the launch want and subsequent wants have to be handled; a null result from tryGetSharedRecordsFromShareKit() means the want carries no shared data.
