QML and Qt Quick

@FishBoneEK hi, Which version of Qt are you using now ? On which platform ? Did you check the bug report system to see if it's something known ?

@SGaist Just had a look to the post. Login is fine, Qt email and Atlassian email matches, I can see the issues on bug tracker. However the "Create" button still won't work. Plus I can't access the account profile page, it says: This page has restricted content This page has restrictions that limit who can view it. Try going back home or asking a workspace admin for viewing permission.

This behaviour is still not documented (Qt Bug Tracker). The special modifier handling is implemented in QWindowsPointerHandler::translateMouseWheelEvent. A WM_MOUSEWHEEL event is treated like a WM_MOUSEHWHEEL event: const QPoint angleDelta = (msg.message == WM_MOUSEHWHEEL || (keyModifiers & Qt::AltModifier)) ? QPoint(delta, 0) : QPoint(0, delta);

@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.

Hi and welcome to devnet, Can you share a minimal runnable script that shows this ? Also, which version of PySide6 are you using ? With which version of Python ?

@GrecKo said in How to use qmlpreview?: I'll ask Qt commercial support about this. Did you get a chance to ask them and are there any pointers?

Thank you, I will take look at it.

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))
