SUMMARY Files and folders do not respond to drags made with a tablet pen. This includes both the main view and sidebar STEPS TO REPRODUCE 1. Use a tablet pen 2. Attempt to drag a file OBSERVED RESULT The file is not dragged, and only registers the initial click EXPECTED RESULT The item is dragged as when using a mouse SOFTWARE/OS VERSIONS Operating System: Fedora Linux 40 KDE Plasma Version: 6.0.5 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.1 Kernel Version: 6.8.11-300.fc40.x86_64 (64-bit) Graphics Platform: Wayland Processors: 16 × Intel® Core™ i9-9900K CPU @ 3.60GHz Memory: 31.1 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 1080 Ti/PCIe/SSE2 ADDITIONAL INFORMATION Tablet: Wacom Intuos Draw Small - CTH-490 Dolphin version 24.05.0 Enabling touch mode on my tablet, so it functions as a touchpad, and then using my hand does work correctly. This issue seems specific to using the tablet pen. I can change the Zoom, and I can re-order tabs with a tablet pen.
I think this could an issue in qt itself. After reproducing the problem on neon unstable and adding some logging, I found that both tablet and mouse behaved the same up until dolphin executes the QDrag. However when using a tablet pen, Dolphin doesn't receive any subsequent drag events. I then tried the drag and drop examples qt provides (https://code.qt.io/cgit/qt/qtbase.git/tree/examples/widgets/draganddrop?h=6.7) and got the same results, where dragging only works with a mouse and not a tablet pen.
