QML and Qt Quick

Thank you very much for your answers, gentlemen.

See http://qt-project.org/doc/qt-5.0/qtquick/qtquick-visualcanvas-topic.html#visual-parent for more information about this. The short answer is that there are two different "parenting" concepts in QtQuick (object ownership parenting, and visual item parenting). In most cases, the visual item parent is also the object ownership parent, but there are cases where they can be different. Cheers, Chris.

ooops. You should not have both. May complete posting of the code would helped. It is good that is solved now. Happy ending. Enjoy

Yes, it's working fine now. I thought there would be a better way to do it, but this seems to be correct and works as expected.

yep, the same for me. Qt Creator marks my import as an error but at the same time I'm able to run my application without any problems. But if I use qmlRegisterType instead of qmlRegisterSingletonType everything is ok. P.S. It's actually one of the reasons why I'm thinking about using ContextProperty instead of registring singelton http://qt-project.org/forums/viewthread/37707/

Here's an example for doing heavy maths in another thread to stop the GUI from freezing: http://qt-project.org/doc/qt-5/qtcore-mandelbrot-example.html

Thx for the quick answer. And yes, after spending hours on finding a proper solution this is definitely is the easier way of doing it.

Alright, i'll give it a try, thank you.

Answer from Digia: bq. As Image requires url, you cannot directly specify QImage for it. One option would be to change the QImage to QString and then use the QString as image source. So add images to resource file and use in cpp: Constructor: @Animal(const QString &type, const QString &size, const QString &image);@ Adding an animal: @model.addAnimal(Animal("Wolf", "Medium", "my_image.png")@ and then in qml: @ListView { width: 200; height: 250 model: myModel Component { id: modelDelegate Item { width: 180; height: 40 Row { Text { text: "Animal: " + type + ", " + size } Image {source: image} } } } delegate: modelDelegate }@ Another option would be to use QQuickImageProvider class. http://qt-project.org/doc/qt-5.0/qtquick/qquickimageprovider.html An example of how to use QQuickImageProvider can be found from: \qtdeclarative\examples\quick\imageprovider

Well you could try something like that: "Custom QML Object":http://stackoverflow.com/questions/16534489/qml-control-border-width-and-color-on-any-one-side-of-rectangle-element Try to create a custom QML Object which looks like the border you want and is always on top.

Glad to hear :) All the best with your project!

Ah I see. Thanks so much for your help!

Hi, If i have understood your problem correctly, may be "propagateComposedEvents":http://qt-project.org/doc/qt-5.0/qtquick/qml-qtquick2-mousearea.html#propagateComposedEvents-prop would help you.

You're welcome ! Since it's working for you now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)

You're welcome. :) Happy coding!

You're welcome :) Happy coding!

Hi, Can you provide a minimal example for the note ?

Hi, You can try something like this: @ property list<QtObject> myModel: [ QtObject{text: "A"}, QtObject{text: "B"}, QtObject{text: "C"} ] Row { id: xRow anchors.centerIn: parent visible: true spacing: 5 Repeater { id:xRepeater model: myModel Image { id:xImage width: 78; height: 70 fillMode: Image.Stretch source: "imgs/x.png" smooth: true Text { id: xText anchors {centerIn: parent} text: modelData.text font {pixelSize: 36} color: "black" } }//end of image }//end of repeater block }//end of of row block @ This way, changes in your object properties should cause binding reevaluation. However, I don't know how this would be mapped into C++. Probably a QList<QObject*> or a QVariantList but you will have to test this to be sure.

Which compiler? Qt 4.7 is very old, but I got multimedia working with the MinGW 4.4 compiler before. Can you please post your .pro file?
