    @Jonas-Karlsson Thanks for the reply! However I cannot file a bug report on the Bug Tracker (the "Create" button won't respond). It would be nice if you would report it instead of me. P.S. The bug in the bug tracker, pretty ironic? Thanks!

    @ECEC said in Bind to another model's data in a delegate: @jeremy_k , A proxy model can only have one source though, so surely this would still require connecting to model B's dataChanged to be aware of relevant changes (i.e units changed)? QAbstractProxyModel::setSourceModel() only accepts one model. That doesn't mean that a proxy must use or limit itself to this interface.

    @petero3 Thanks for the update. Because we have to stick to older Qt version I found workaround to use QQuickPaintedItem. Visually it gives me the same effect and CPU impact (if any) is bearable. ... only hands were dirty :-)

    @huy2910 Any reason not to use more recent Qt version? Especially when using most recent Android version.

    @salirezag said in QML File Manager App Suddenly Crashes: @GrecKo It didn't help. Just a segmentation fault was thrown. You don't have any stacktrace? @salirezag said in QML File Manager App Suddenly Crashes: When I comment out NetworkSettings it works. It seems that this component is soaking up my memory. But I don't know why :). Figure out why then. How many memory is used/free when your app crashes? Run it through a memory profiler.

    I started getting "1060 Out of heap space" when I upgraded to Qt 6 and VS 2022. The "-std:c++17" flag triggers it. The solution was to update to VS 2022 ver. 17.14. This may be unrelated, but I'm posting it to help anyone else coming here with this problem.

    Hi, I recognise your name from SFOS forum/Openrepos. I pasted your code into a new project, I cannot reproduce your problem. I don't get the white background as per your video. I am using the latest Qt Creator 18.0.1 (Built on Dec 9 2025 12:49:14 based on Qt 6.10.1 (MSVC 2022, x86_64))

    @jchaviano I have met exact the same issue, the error string I got from "Video qml" onErrorStringChanged, is "I/O operation failed". I am using Android 11 and Qt5.15. Have you resolved the issue?

    The workaround in this post might help. Basically it shows the popup again if it is dismissed by clicking somewhere else: QML: MessageDialog closes on click outside
