Subject: [PATCH 38/48] backends/x11: Observe multiple pad mode switch buttons
|
|
in a group
|
|
|
|
Some tablets like the Cintiq 24HDT have several mode switch buttons
|
|
per group. Those are meant to jump straight to a given mode, however
|
|
we just handle cycling across modes (as most other tablets have a
|
|
single mode switch button per group).
|
|
|
|
So spice up the mode switch handling so we handle multiple mode
|
|
switch buttons, assigning each of them a mode. If the device only
|
|
has one mode switch button, we do the old-fashioned cycling.
