Commander settings


The complete list of global Commander settings are listed below and reside in the UPDD settings database. Application, Gesture and actions definitions are held in propriety file formats managed directly by Commander.

Most of the global settings can be adjusted via the Commander setting dialog. However all of the global settings can be set by the command line interface. They can also be set using the UPDD API if required.

Being global settings they can be set with the command 'upddutils nodevice set "commander setting name" value'.

 upddcommander.applicationsettings.tablet_posts_mouse_events_app_id app  For pen events received over the 'app' post mouse events - See Note 2 

 Notes:

  1. Pen input bypasses Command gesture processing so will automatically generate clicks and clicks and drags. A touchscreen was being used that generated both touch data but also pen data if the finger made a small (width/height) contact (finger nail?). The user was using one finger swipe left and right in a presentation system to move slides back and forth, but if pen data was received it generated a click or click and drag that affected the presentation. This setting was added to instruct Commander to ignore pen data.
  2. Pen posting were discovered to cause issues in a particular version of Chrome. This setting can be used to request that mouse events are posted rather than tablet events
    Specifies which macOS applications should receive mouse input rather than tablet input when using a pen device. The value must be a comma or space separated list of application bundle IDs.
    The bundle ID is the globally unique identifier for that application that is consistent regardless of the system language, hence needing to use that instead of the application name.
    To use this setting to prevent Google Chrome (and derived browsers) from receiving tablet input, you can set it to the following:
    com.google.Chrome org.chromium.Chromium
