  Format choise is up to you :) If you need to store some tree data or you want to edit it in your text editor later or you just need non-binary format then xml is ok.

  Be aware that if you are using QDeclarativeView::showFullscreen() you will need to set the geometry manually, otherwise your view won't show up. In addition, the order is important: set the source set the resize mode set the geometry show @ int main(int argc, char* argv[]) { QApplication application(argc, argv); QDeclarativeView view(QUrl("main.qml")); view.setResizeMode(QDeclarativeView::SizeRootObjectToView); view.setGeometry(application.desktop()->screenGeometry()); view.showFullScreen(); return(application.exec()); } @ @ Rectangle { color: "green" } @

  Once we have Qt Quick Components ready, we should have all these widgets come ready-made. And about "should it be a global item", I don't know any other way of doing it. May be there is a way??

  lv->property("currentItem"); But normally you want QML to be calling things from C++, not the other way around. Perhaps you could expose the C++ functionality as a function, and call that function from QML with the currently selected item as an argument?

  [quote author="Vijay Bhaska Reddy" date="1308651284"]@sigrid, thanks for your reply. But did not get your answer. The question was is on how to assign id to a dynamically created object.[/quote] That is because you asked the wrong question. You asked how to assign an id. As you say yourself earlier on, that is not possible: [quote author="franziss" date="1308625139"]I understand that we cannot dynamically assigned id to the dynamically created object.[/quote] So, asking that, is obviously the wrong question. What you really wanted to know, is given that you can not use ids, what kind of mechanism you can use to refer to dynamically created objects. That is the question that sigrid answered for you.

  Building the branch 4.7 from git (what will become 4.7.4) or the tech preview of Qt 4.8 are the ways to have QtQuick 1.1 at the moment.

  also i got a problem when using a qml file that contains mouseareas. In a QdeclarativeView everything works fine. but when i put the same qml file into a QDeclarativeItem with following code @QDeclarativeEngine* engine = new QDeclarativeEngine(); QDeclarativeComponent* component = new QDeclarativeComponent(engine, QUrl::fromUserInput(qmlFileName)); QDeclarativeItem *item = qobject_cast<QDeclarativeItem *>(component->create());@ i dont recieve any mouse relating signals in my qml. do i have to set specific flags?

  Hi, Could you please double check your XML file - it contains some mistyped characters as I see it. Also there is opening <p> which is missing...so please clean it first a bit and then specifiy exactly what do you expect to grab from the xml as pass it over to the role.

  If I understand your situation correctly, the correct solution would be to expose the Consumer type to QML. If there is only one instance of the Producer class, then each Consumer class can find that instance using a static method on the Producer class, inside the C++ constructor. Assuming that the Consumer class is a QObject derived class, you just register it with QML and instantiate it in QML when ever you want one. From QML you can access the properties and data of the Consumer object to display them. You can do your special setup in the C++ constructor. This does not require a plugin if you have your own C++ application already, you can register types for use just within your application.

  Thank you for your advice,now I use javascript RegExp to get the tag content,but QXmlStreamReader is extremely nice.Thanks again !My regards! [quote author="Andre" date="1308471518"]Very simple: QRegExp is not a parser. Do not use it to parse XML. Instead, use the right tool for the job: QXmlStreamReader or XMLPatterns. Believe me, you will make your life easier that way. You might be able to eat your soup with a fork, but using a spoon will certainly result in a more pleasant eating experience. The same goes for solving programming problems. Because you want to do that from QML, you'll either need to such such a facility from javascript (is there such a thing? I don't know.), or expose a C++ object that does the work for you into your QML context. [/quote]

  [quote author="Vijay Bhaska Reddy" date="1308470508"]This should work. Did you try to debug or are you getting any compile time errors. finestraPrincipale => does this get valid pointer?? after the statement @QObject *finestraPrincipale = view.rootObject();@ [/quote] If it wasn't a valid pointer (i.e. 0) he'd get a SIGSEV anyway on the findChild method. @spode: You could try to use the objectName() method to find out whether you actually have the right object

  I solved it here: http://developer.qt.nokia.com/forums/viewthread/5862/#38285 Basically, you use macros on the C++ side to introduce a property to QML, the rest can be done in Javascript based on that property (or properties if you like to have many).

  Hi, There isn't currently a way to link them, but there is a suggestion for this in the bug tracker: "QTBUG-17323":http://bugreports.qt.nokia.com/browse/QTBUG-17323 . I'd suggest leaving a comment there with your usecase if possible -- it would be helpful to see more examples of where this plays out in real life (e.g. the kind of internal changes that cause this sort of situation). Thanks, Michael
