wacom shortcut sidepannels

Software darktable
1

Hi All,

I am trying to map wacom tablet to the side panels (scroll up/down) in darktable (without success).

Currently I am using the wheel on the mouse and if I hold Ctrl+Alt and scroll the wheel - I can move the modules (scroll) up/down. This works very well if I am to only use the mouse.

When I switch to the tablet (wacom) - I can’t seems to find a way to achieve the above functionality. Ideally - I would like to see Ctrl+Alt+ drag the stylus up/down to emulate the behavior of the wheel.

Does anybody know how to do that?

PopOS 22.04 - DT 4.0.1
I don’t have any specific tablet configuration except what comes with Gnome (the normal UI configuration).

Thank you,

B

There are potentially a few ways to achieve this. They all involve using the terminal :wink:

No idea what will work for you, but here are some pointers:

Thank you, I will give that a try. I was hoping there is something within DT that I maybe missing - because DT now supports even MIDI controllers. But I guess there is nothing that I can utilize directly.

I guess this maybe a good feature request - extend support for tablets but not sure how many people are using them.

If your tablet has enough buttons, you can probably set one of them to be the scroll button.

Here’s how I have my trackball configured:

xinput set-prop "Logitech USB Receiver" "libinput Scroll Method Enabled" 0, 0, 1           # Enable button for scrolling
xinput set-prop "Logitech USB Receiver" "libinput Button Scrolling Button" 10              # "Lock" button
xinput set-prop "Logitech USB Receiver" "libinput Button Scrolling Button Lock Enabled" 1  # Toggle instead of hold
xinput set-prop "Logitech USB Receiver" "libinput Horizontal Scroll Enabled" 0

I have this in my .profile (.xprofile probably works as well).

It should be possible to do something similar with your tablet.

Can you just use the built in way to do it with the tablet??

I would love to but it doesn’t seems to work on Linux. Were you able to make it work on Linux?

I bought one with some Dell dollars…haven’t really made the leap to use it… But that feature does seem to work… I have only tried on Windows…

I happen to watch a video from AP on dodging and burning. In it - he did mention that he is using wacom but he also confirmed that he pretty much use it for shapes creating. I will check github if there is a feature request at all.

And yes - there is one from quite a while back but still in the works.

The tablets were always too pricey for me. Only recently they fell within a more reasonable price. I guess it will take some time to have a better adoption and more enhanced support.

Assuming there’s nothing funky going on, this should work:
