Okay, that got me a little further, many thanks! I've added the following
code to pyglet_view
@PygletView.method('v@')
def tabletProximity_(self, nsevent):
capabilityMask = nsevent.capabilityMask()
deviceID = nsevent.deviceID()
# these are listed
https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSEvent_Class/#//apple_ref/doc/uid/20000016-SW32
# but do not seem to work here
#enteringProximity = nsevent.enteringProximity()
pointingDeviceID = nsevent.pointingDeviceID()
#pointDeviceSerialNumber = nsevent.pointDeviceSerialNumber()
#pointDeviceType = nsevent.pointDeviceType()
self._window.dispatch_event('on_tablet_proximity', capabilityMask,
deviceID, pointingDeviceID)
@PygletView.method('v@')
def tabletPoint_(self, nsevent):
absoluteX = nsevent.absoluteX()
absoluteY = nsevent.absoluteY()
absoluteZ = nsevent.absoluteZ()
buttonMask = nsevent.buttonMask()
rotation = nsevent.rotation()
pressure = nsevent.pressure()
tangentialPressure = nsevent.tangentialPressure()
tilt = nsevent.tilt()
vendorDefined = nsevent.vendorDefined()
self._window.dispatch_event('on_tablet_point', absoluteX,
absoluteY, absoluteZ, buttonMask, rotation, pressure, tangentialPressure,
tilt, vendorDefined)
and this is printing sporadic info - is there another type that I'm
supposed to be looking for? I'm getting maybe 20% of my tablet presses,
which is not helpful as I'm developing a drawing application.
Maybe it has something to do with event coalescing?
I'm unable to get tablet proximity information out either... any further
tips or tricks would be greatly appreciated. Thanks again
Andrew
