fix shift buttons with certain input devices (huion tablets)
Closed, ArchivedPublic


I made a fix for the shift button that has been reported a couple of times to not be working with certain input devices, and since i just got some huion tablets and experienced the issue myself it was something i could directly test.
However since my knowledge with coding is limited i might have not understood some of the decision for the earlier implementation.


I have tested this only on PC so far, so if someone could test this on a mac would be great.

OS: windows 10 64bit
Devices Tested:

  • Wacom Intuos Pro (5th generation)
  • Huion H950P
  • Huion Camvas 13 pro
  • PC Keyboard (US layout)

@dan den (dan) grauer I’d like to know why you assign that to me? That’s not especially my area, certainly not for win/mac OS's…

And please submit a diff (, which you can then reference in both T49239 and T59854, much easier to handle review that way. ;)

@Bastien Montagne (mont29) ive seen you active on some older ticket related to this so i thought you would be the correct person to assign, guess i was wrong. sorry for that.
thanks for mentioning the diff creation, its really a lot easier than the patch.

No proplem, please continue the process though (create a new revision using the 'continue' button on the diff page) ;)

Then we can close that task.
