I'm trying to set the text of a TextArea from C++, but it the page is going plain dark ( splash) with no error messages in the logs.
I have tried it in both simulator and Dev Alpha device and same thing happend.
QmlDocument *qml = QmlDocument::create("logger.qml"); AbstractPane *root = qml->createRootNode<AbstractPane>(); txtArea = root->findChild<QObject*>("txtName"); // QString temp="";//txtArea->text(); // temp.append("Text:"); txtArea->setProperty("text", "Text:"); qDebug() << "JSON data loaded OK!"; Application::setScene(root); }
If i comment the 'setProperty' line, the empty text area comes just fine.
As you would notice I tried the setText too, but that also failed.
Solved! Go to Solution.

I changed a sample I have that uses a TextArea to use a QString instead, commenting out all TextArea methods and just doing your setProperty line. This worked fine for me. I also tried just changing the findChild to findChild<QObject*>. When my variable is a TextArea*, this gives a syntax error unless I do:
So if the previous suggestion is not enough, change your txtArea variable to a TextArea* and check that the findChild actually returns something.
