Description Tyson Tan 2019-06-23 14:19:39 UTC 
SUMMARY
In Plasma 5 Application Launcher, I cannot not drag its scrollbars with graphics tablets when my cursor is over the slider. However, I can drag the scrollbar with graphics tablets when the cursor is on the right of the scrollbar. Mouse is unaffected. Tested on Wacom Cintiq Pro 13.

BTW, in dolphin, I can drag the scrollbars anywhere close to the slider, both on its left and right, I don't have to drag exactly over the slider to make the scroll.

Tablet support in QtQuick isn't on par with QtWidgets yet. I suggest to test newest Qt (5.13.0), and if this doesn't resolve the issue, then report it to Qt developers.

Still an issue with the current as well as the new Kickoff.
Comment 3 Mikel Johnson 2021-01-25 07:46:23 UTC 
this might be a components issue, pls investigate

Who is that a question for?
Comment 5 Mikel Johnson 2021-01-25 17:14:32 UTC 
you I guess
Comment 6 Mikel Johnson 2021-01-25 17:15:40 UTC 
no obligations though
Comment 7 Nate Graham 2021-01-25 20:00:47 UTC 
Stylus support for UI controls is kind of a mess throughout Plasma, but I don't think that's what's going on here. For example using a stylus with a Plasma scrollbar in the clipboard applet works oddly, but in Kickoff it doesn't work at all. In fact nothing works at all with a stylus in Kickoff. It feels like there's a global MouseArea eating all stylus events. Knowing that there is in fact a big MouseArea in Kickoff somewhere, I suspect that something similar to this is what's happening.
