QML and Qt Quick

What was it ?

@jsulm I meant modules such as import QtQuick 2.12 import QtQuick.Window 2.12 import QtQuick.Controls 2.15

@mzimmers Right, ListElements are a collection of roles. If you want to set "dynamically" those roles, you should play with the javascript functions of ListModel, and implement some kind of mechanism (depends on your use case) to update it.

I would created a class that handles the loading/unloading of QTranslator objects. You can then use an instance of it as a context property so you can call the method you want to change the language.

If you are using Qt Creator click on the Welcome icon in the left of Creator side bar. Then search for "game". Then look at the QML Advanced Tutorials 1, 2, and 3.

@oria66 Thank you so much! Works perfectly here.

Did you find a solution for the problem? I am facing the same problem - interestingly it works when using widgets but in Qml I see the exact same problem.

Sigh...I love when I find the answer immediately after posting... Container currentIndex TabBar { id: root currentIndex: { if (plateNavViewModel.viewingTheYield) { 0 } else { 2 } } I know the hard-coding is bad, but...it works.

It seems you are getting your technologies mixed up. The example you run is for the accelerometer (movement) but you are talking about a temperature sensor. Just adding bits of code is not going to make code run, there is a little more to it than that.

@AI_Messiah said in How do I load multiple images to be accessed by a Canvas as an array in QML: loadImage(mycanvas.oneEl); Shouldn't this be loadImage(oneEl)? oneEl is not a property of mycanvas. Edit: isImageLoaded will tell you if its loaded. https://doc.qt.io/qt-5/qml-qtquick-canvas.html#loadImage-method

@SGaist - Thanks for the information. The issue is resolved now. Below is the sample code QFutureWatcher<void> *modelThread = setFuture(QtConcurrent::run(this, &classname::method));

@KroMignon Some functions in QtQuick.Extras, QtQuick.Controls and QtQuick.Shapes, also I believe QtCharts is not available in Qt 5.11. Mainly visual features for styling.

Simply use a QList<QObject*> or QVariantList, depending on your space ship backend implementation. If you want a QML-only solution, for some reason - you can parent all your space ships under a single Item and then access them using item.children.

@fcarney said in accessing elements of a ListModel: onBottleListChanged: updateListModel() Oh, OK...I see my problem now. I was trying to use this line of code from within the repeater. I see now that it should go in the containing Rectangle. You call the function that rebuilds your ListModel. Don't you want that to update when it changes? Also, you said you had two lists of data. Does it have a signal too? I have two sources of data: one in C++ and one in a QML ListModel. I actually have 2 QML ListModels, but only use one (which one to use is determined at runtime by an environment variable). The only signal is emitted by the C++ update function; nothing in the ListModels. As it turns out, I've been able to eliminate the use of the QML update function entirely (though I still need the getColor routine() above, so I won't need to use this feature here, but this has been very educational. Thank you for all the help.

Sorry, that's one of the corner of Qt I do not have much experience with.
