Hi all I have problem with my QML code.
I made mistake and I went to put certain size to elements and now I have problem when putting app on other devices.
I will paste you my code where I have width and height so you can change it to show me how to work with dynamic resizeing.
I need to say that I am calling qml file from qt with this code:
QDeclarativeView *view= new QDeclarativeView;
ui->setupUi(this);
setCentralWidget(view);
QDeclarativeContext *ctxt = view->rootContext();
ctxt->setContextProperty("funkcije",this);
ctxt->setContextProperty("myModel", QVariant::fromValue(MainWindow::dataList));
view->setSource(QUrl("qrc:/gui.qml"));
view->setResizeMode(QDeclarativeView::SizeRootObjectToView);
showFullScreen();
And here goes my QML code:

I have put all the code with width and height so you can see what I have done wrong. And please if someone can say me how to make it dynamically fill.
It’s unfortunately tricky to get perfect, as it’s likely that as the screen size shrinks you might actually want the buttons to be bigger and to drop content from the screen to ensure the user can access and read everything ok.
But the general approach is actually to set a scale factor in the C++ side:
And then on the QML side, use that everyone to scale all the objects:
That way you can adjust the scale variable to change everything’s size. Having said that, many people end up with different QML files depending on the platform size though.
