There's no simple "switch drag to the right mouse button" feature in OSD, but it's possible you could implement it. You'll have to disable the viewer.innerTracker.dragHandler by setting it to null, and then create new functions for these three handlers:

  • viewer.innerTracker.nonPrimaryPressHandler
  • viewer.innerTracker.moveHandler
  • viewer.innerTracker.nonPrimaryReleaseHandler

You'll need to implement your own drag functionality, since OSD doesn't have a "non-primary drag" handler. As for the actual panning functionality, you can take a look at how it currently does it with the left mouse drag.
