Hello,
I was told to report a bug here with this information:
Krita
  Version: 4.0.1
OS Information
  Build ABI: x86_64-little_endian-llp64
  Build CPU: x86_64
  CPU: x86_64

Krita does not respond correctly to the space button when it is mapped to the button of a wacom pen.

I will list what works, and then what I'm doing, and then what doesn't work so everyone can easily follow along:

- Open Krita and create an image. Hold down spacebar, cursor turns into a hand, now when you click with the mouse and hold and then move the mouse, the canvas will pan around. So far, everything is working as intended.

- Now I want to do the same thing by putting the spacebar button on a pen button on the pen of my wacom tablet:

- Open wacom driver dialog. Set the lower button of the pen to press the spacebar. Open notepad or chrome or whatever and confirm that it's working (it is, you can even press buttons with that as if you'd hit spacebar on the keyboard. all good).
Now open Krita, create image, press and hold down that pen button (which was mapped to space). The cursor correctly turns into a hand icon. Now when you touch the pen to the tablet *nothing happens*!
It should at least turn into that "grabbing hand" thing like it does with mouse+keyboard, but it doesn't.
Moving the pen around (while still holding down the mapped space button on the pen and still touching it to the tablet) does nothing, it does not move the canvas.



Additional information that is likely pretty interesting:

- When I go to the window in Krita where they canvas settings are and expand "PAN CANVAS" and then set new keys for it. Then it actually works there.
You know the tiny window where you click on it to set a key-combo and then press the key and that gets registered? That actually works. I press the "none" with the pen, and then it starts listening, and when I press the button on my pen it actually says "Space" correctly.

- As I said above, when pressing the pen button it even turns the cursor into a hand, but touching+dragging won't work.

- Pressing the "space" key on the pen, and then moving the mouse also does not work.

- Pressing space on the keyboard and then touching and dragging with the pen does not work either.

- Drawing with a normal brush works fine with the pen and the mouse with no problems. Pressure sensitivity also works fine when drawing.


Tablet is a wacom intous.
Windows 7.
Newest driver from the wacom website. It says "DRIVER VERSION: 6.3.29-6".


I hope that is enough information.
Let me know if now.
