      I'm not sure I understand your English. I'll assume you meant "when I click a button in QML, I want my webview, declared in C++ (QtWidgets) to go to a certain URL". If that happens to be the case, the answer is quite simple. You can use signal/ slot connections to manage your communication. Or even simple Q_INVOKABLE method.

      For example:

      create a Qt class (it has to inherit from QObject, remember!): say, myText. There, declare something like @ Q_INVOKABLE void setWebViewUrl(const QString &newUrl); @

      add this class to QML by calling @ QDeclarativeView::rootContext()->setContextObject(new myClass *instance()); @ (you have to provide a QDeclarativeView object, of course)

      you can now use this new method inside your QML code, it will be available everywhere. I'll give an example for MouseArea:

      @ MouseArea {
      onClicked: {
      setWebViewUrl("my.new.url.com")
      }
      } @

      That's it. Happy coding :)

          Re-read 3rd point I've made. It's globally available once you add the QObject that declares it to rootContext.
