QML and Qt Quick

Yep, thx anyway.

p.s. Might be worth mentioning, in Qt4 (Qt Quick 1) QtCreator added qmlapplicationviewer to start up the gui, with @QScopedPointer<QmlApplicationViewer> viewer(QmlApplicationViewer::create());@ put into main.cpp. QtQuick.Controls 1.0 needs QtQuick 2, which in turn needs qtquick2applicationviewer rather than qmlapplicationviewer, e.g. @QScopedPointer<QtQuick2ApplicationViewer> viewer(new QtQuick2ApplicationViewer());@ But this actually conflicts with ApplicationWindow. Both ApplicationWindow and QtQuick2ApplicationViewer create a root window, so there is conflict over which window is to be used. Instead, to use ApplicationWindow, in main.cpp we should use QQmlApplicationEngine instead of QtQuick2ApplicationViewer, e.g. @QScopedPointer<QQmlApplicationEngine> engine(new QQmlApplicationEngine());@ followed by @ engine->load(QUrl("qrc:/qml/main.qml")); QObject *topLevel = engine->rootObjects().value(0); QQuickWindow *window = qobject_cast<QQuickWindow *>(topLevel); window->show();@ instead of @viewer->setSource(QUrl("qrc:/qml/main.qml")); viewer->show();@

Qt documentation has a great entry on signals and slots, just read it ;) In general, a slot is just a standard C++ method, but it has some additional features: it can be invoked through meta object system (QObject::incokeMethod()), signals can be connected to it, and it can use the QObject::sender() meta information (although it's pretty dangerous). Another benefit is that it can be invoked indirectly (Qt::QueuedConnection), which helps greatly in making asynchronous APIs, fluid GUIs and safe communication with threads.

Found it! @export QT_QPA_EGLFS_HIDECURSOR=1@

Thanks Jens, Your replys always help me a lot!

Entirely correct. Also note that at least for button, you could also do it like this: @ Button { width: 100 Label { anchors.centerIn: parent text: "hello" color: "red" } } @

Torgeir, you must be a mind reader. After seeing the advice of JKSH I've been thinking about how to implement a collection of mass points (perhaps dozens, but not 10K). You brought up the previously-unknown -- to me -- item "Repeater". Perhaps I should retitle the posting as "[SOLVED -- even better]". Thanks.

Sorry, as you can see, when I upgraded to 5.1 and created new projects it went away. I really did not have time to work out why and it has not happened since. Sorry.

QML windows? Do you mean visual items or views? Please read "the document":http://qt-project.org/doc/qt-5.1/qtqml/qml-qtqml-models2-objectmodel.html And you should read the document related to scene graph.

Thank sohail I knew Shader Effects, I want to use Shader Effects too. However after Shader Effects are rendered, how to save results? The only way I know is grabbing drawing frames. The issue of grabbing drawing frames is that I cannot get full-resolution results because screen resolution is limited.

Hey, thanks for the reply. funny enough the same bug was apparently reported two days ago there... If anyone else is facing this problem, here is the direct link: "QTBUG-33729":https://bugreports.qt-project.org/browse/QTBUG-33729

Thanks a lot for the Info Jens! That is indeed good news for me, and i will try and get a hold of the Alpha build to see how it works out! - would be glad to possibly give feedback Thanks again

Thank you! Then I think I can handle it form c++ by implementing a model by sub classing QAbstractListModel. TaleViewDelegate idea is great. I would like to see it on a future version. :)

Well surely they could have an optional flag that you can set to use the alpha channel, so that if you don't want it then you still have the improved speed?

Ok, got it working right after posting this... I had to set also passwordCharacter to "*" in addition to setting inputMethodHints to Qt.ImhNone.
