I'm using intuos pen and touch small( CTH-480 ) as the digitizer.

This issue occurs because the hand touches the tablet surface before the pen enter the proximity of the surface. I tried to change CursorProximity, but input-wacom doesn't support CursorProximity for CTH-480 for now at least.

GIMP and mypaint ignore tablet touch clicks.

Can you make krita canvas ignore table touch clicks?

How about adding an option to ignore tablet finger clicks on canvas in preferences dialog?
tablet finger clicks can be useful outside canvas(e.g., radial menu, toolbar, etc)
Comment 4 Halla Rempt 2014-04-28 13:41:58 UTC
Yes, an option to ignore touch on the canvas should be added. It's also pretty easy to do.
Comment 5 Halla Rempt 2014-04-28 13:46:50 UTC
Argh... No... I am wrong, it's pretty easy to disable touch for pan/zoom, but pretty hard to do that for finger-painting, because we just get a mouse event for those and cannot distinguish between a mouse-mouse event and finger mouse event.
Comment 6 Dmitry Kazakov 2014-05-05 08:55:04 UTC
Well, I could search for a solution, if I had a touch-enabled tablet device. Probably, we could spend some time on it during the sprint in May?

Hi, crockabiscuit!

Could you tell, do you use the wireless adapter for the intuos or you connect it directly using the cable? It seems like the tablet works quite strange on linux when using wireless...

I don't have a wireless adapter.

Wouldn't it be savvy to document disableTouchOnCanvas option somewhere like README?
Comment 11 Halla Rempt 2014-06-01 08:19:47 UTC
We'll probably add it to the gui after making sure it works everywhere :-)
