从C ++访问QML对象 [英] Accessing QML objects from C++

问题描述

以下是编写的代码，用于将QML文档加载到c ++.

Following is a code written to load a QML document to c++.

  QmlDocument *qml = QmlDocument::create("asset:///main.qml").parent(this);

    // Create root object for the UI
    AbstractPane *root = qml->createRootObject<AbstractPane>();


    app->setScene(root);
}

如何访问QML文档的对象，例如按钮等；来自C ++.我需要访问它们以在QML文档中找到特定对象的内存地址.

How do I access the objects of the QMLdocument, such as a button etc; from C++. I need to access them to find the memory address of a specific object in the QML document.

推荐答案

ImageView* iv= root->findChild<bb::cascades::ImageView*>("myImageView");

和QML

 ImageView 
 {
      // ...
      objectName: "myImageView"
 }

别忘了清理并重建项目.

Don't forget to clean and rebuild the project.
