QML and Qt Quick

Did you have a look at the Repeater Component? https://doc.qt.io/qt-5/qml-qtquick-repeater.html

I think it crashes because move up from 2 to 3 equals to do nothing. According to doc https://doc.qt.io/qt-5/qabstractitemmodel.html#beginMoveRows If you want to move 2 to 3 you have to move 2 to 4, but in this case you will have a problem with pre_last & last element. So there is a tricky way to do that: move 3 to 2 void ObjectModel::move(int from, int to) { ... if (from + 1 == to) std::swap(from, to); beginMoveRows(QModelIndex(),from,from,QModelIndex(),to); ... endMoveRows(); }

Have you looked at this page?

I found drag and drop to be finicky. If you haven't already seen this tutorial I would look at it. It helped me understand how to cleanly setup my drags and drops. I still found issues I had to tweak to make work just right. Like dragging items from a list would sometimes leave the source miss-adjusted. I had to tell it to remember its position to fix that. Other times I refreshed the list.

Well, answer is coming after a question even one has googled before it a lot. In the case of using menu, contentData property can be used for the replacing MenuItem's. I think the same approach can be extended on custom types.

@ocgltd said in Don't understand cause of "Cannot assign object to list property" error: Since .children is a list I thought this should work Yes it maybe a list, but a list of what??? I only aware about contentChildren and contentData for Popup component, what is bodyContent? Note: it would work with contentData (with is a list of object), but not with contentChildren because is it a list of Item

@KroMignon Hi, I looked at the example and I also used import QtCharts 2.0 but it does not do anything.

This has nothing to do with Qt, better look for help on some Linux-specific forum. The /dev folder is under complete control of the operating system. You should not try to change how it works! Instead, if you need to talk to such USB device, use common libraries (like libusb) and always search for your device using it's device ID, not path.

I don't know. To notice any performance difference I guess you'd have to spawn 50 of them and test on some slow device. I guess custom-styled Controls 2 are going to be faster due to some optimizations they can do to drawing, but I don't really know this for sure. To me it's more of a question of what do you prefer to use as a programmer, what will be easier to write and maintain.

I'm trying to make the BLE part has a separate static module (LIB) and integrating it into main executables, Everything linked correctly and works perfectly, but I'm getting the error, thanks for trying

What do you mean by "multi process"?
