I have an Acer Aspire Switch Alpha 12 with a touch screen and pen. The pen typically emulates a graphics tablet. I am on Wayland. I was able to click on the network manager applet and see my networks. I attempted to connect to a vpn connection (I could not scroll to the top to see my primary connection). The tap with the pen was registered, but rather than connect, it toggled the expand function. I tried the same on my active connection. I tapped disconnect and instead of disconnecting, it expanded. Operating System: Manjaro Linux KDE Plasma Version: 5.20.3 KDE Frameworks Version: 5.76.0 Qt Version: 5.15.1 Kernel Version: 5.9.8-2-MANJARO OS Type: 64-bit Processors: 4 × Intel® Core™ i5-6200U CPU @ 2.30GHz Memory: 7.7 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 520 Can confirm with my touchscreen's pen. We're not doing any special handling here so I suspect that the cause of this issue is deep within Qt. I notice that I can't actually activate *anything* in the applet with my pen. Touching it to the screen results in an item being expanded or collapsed. Can anyone confirm? I can confirm this with both my Lenovo YOGA 730 and Cintiq Pro 13. I must uncheck "Enable Gesture" in kde-wacomtablet to make touch work. However, neither the stylus or the touchscreen can trigger a button click event in that applet. I supposed it's a Qt issue. I saw familiar things in the past. :p > I must uncheck "Enable Gesture" in kde-wacomtablet to make touch work. > However, neither the stylus or the touchscreen can trigger a button click > event in that applet. Ah, this is actually a Wacom driver bug. You should bug the Manjaro packagers (well, probably the Arch packagers) to implement the fix in https://bugs.launchpad.net/ubuntu/+source/xf86-input-wacom/+bug/1774242 When I do that, it works, so I guess this is all on the Wacom drivers. Sorry but I think you've misunderstood what I meant. Disabling "Enable Gesture" turns the touchscreen from totally useless to generally usable, but it still doesn't work on that specific applet. Regardless of the state of this option, I can't click the network applet's Connect/Disconnect button. I don't think the bug I reported here has anything to do with the one in Comment 4. Gotcha. Still likely an upstream issue, though perhaps a different one. Can you test more things with your pen and see if there is anything it does work for? For example: - Other UI elements on the network applet popup - Other applets' popups - Other Elements of Plasma - QML-based desktop apps such as Discover - QWidgets-based desktop apps such as Dolphin That should help us narrow down where the issue is located. Network applet - can't click Connect/Disconnet button; can't switch Speed/Details tab. Otherwise normal. Removable Media applet - can't click Safely Remove button; can click Open Photos with... or Open File Manager links. So this one is completely broken. Application Launcher applet - can't scroll with scrollbars when dragging over them, only works when dragging the empty space on the right side of the scrollbars. Discover - everything works, and they work better than normal KDE applications. I can click-and-drag to scroll in Discover as if I was using Windows 10 + Windows Ink. Dolphin - I use Dolphin everyday and haven't yet notice any function loss. I figure the condition might be that if you: put a (1) Clickable Object inside of a (2) Dynamically Downward Expandable Area inside of an (3) Plasma Applet, a user can't use their graphics tablet or their touchscreen to click it. Clicks can only be registered as Expanding/Collapsing the Expandable Area. There's definitely something odd in various plasma components and applets here. When I use a stylus on my touchscreen, what works and what doesn't seems almost random. Everything in Kickoff and the Task Manager works. Almost nothing in System Tray applets or its expanded view works. Half of the thing sin the clock popup work and half the things don't. I'm struggling to find a pattern. >I'm struggling to find a pattern.
Then the best next step is to try and make a minimal test case:
qmlscene with a few buttons and steps to reproduce on that.
I would also like to remind everyone that touchscreen DID NOT work either. The changed title of this bug report does not reflect what I'm actually experiencing. *** Bug 432987 has been marked as a duplicate of this bug. *** Created attachment 135768 [details]
repro (?)
currently Kickoff uses HoverHandler to detect hover, however for some reason it messes with the tablet while trying to make a min repro test and for some reason PlasmaCore.Dialog messes with tablet hover works consistently in window but not the dialog not sure why though *** Bug 433026 has been marked as a duplicate of this bug. *** Fixed kickoff. Should come in the next minor release https://invent.kde.org/plasma/plasma-desktop/-/commit/e86a68a5cb168d896393d6548b22ceacb839c82e *** Bug 409078 has been marked as a duplicate of this bug. *** Mikel Johnson's patch fixes Application Launcher, but the issue in Network Applet and Removable Media Applet still occurs. Dolphin does not work properly for me. This might be because I am on 2x HiDPI. When I try to select a row in the file listing or the list containing places/devices, the selection is off by some distance. The misalignment worsens when I move Dolphin to the bottom right corner of my screen, as compared to the top left corner. This means I am unable to actually open any folders or files. Clicks to the list headers are also misaligned horizontally, causing clicks to the left part of "Name" to go to "Size" or "Modified". The good thing here though is that clicking actually has an effect. The big buttons, the address, and the bottom slider don't work. The window decorations do work. Also, I don't remember whether the alignment was fine a while ago or I am confusing this with my attempts at touch. This also affects System Settings. The taskbar's calendar, desktop switcher, opening Kickoff, launching pinned applications, focusing running applications, clicking tray icons, status and notifications, and show desktop work. The WiFi applet still doesn't work properly. I can't scroll or connect/disconnect. I can though enable/disable WiFi, search, and clear search. Touching the stylus down on an item causes it to expand and collapse. Switching from "Speed" to "Details" in the active item doesn't work. Nothing inside Kickoff works. Operating System: Ubuntu 21.04 KDE Plasma Version: 5.21.0 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2 Tablet: Intuos Pen Small [033B] Everything in kickoff is working for me with a stylus now. Let;s aboid this being a catch-all "everything is broken" bug as those are never actionable. Instead, please report individual issues with stylus input being broken. Marking this as a duplicate of Bug 426079, as that's originally what was reported here. I'll see if I can fix it. *** This bug has been marked as a duplicate of bug 426079 *** |
