我正在尝试从 qml TextField 中获取用户输入并传递给 c++,但只有在文本属性值为硬编码(常量值)时才有效。
c++
QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
QObject *rootObject = engine.rootObjects().first();
QObject *serverField1 = rootObject->findChild<QObject*>("serverField1");
qDebug() << serverField1->property("text"); //Here I expect to get user input
Qml
ApplicationWindow {
id: applicationWindow
visible: true
width: 300
height: 550
TextField {
id: serverField1
objectName: "serverField1"
width: 200
height: 110
// text: "hardcoded value" //If text is const value, qDebug will get data from this property
}
}
