To learn more about TUIO (which is itself based on the OSC protocol), please refer to http://tuio.org -- The specification should be of special interest. Configure a TUIO provider in the config.ini ------------------------------------------- The TUIO provider can be configured in the configuration file in the ``[input]`` section:: [input] # name = tuio,: multitouchtable = tuio,192.168.0.1:3333 Configure a TUIO provider in the App ------------------------------------ You must add the provider before your application is run, like this:: from kivy.app import App from kivy.config import Config class TestApp(App): def build(self): Config.set('input', 'multitouchscreen1', 'tuio,0.0.0.0:3333') # You can also add a second TUIO listener # Config.set('input', 'source2', 'tuio,0.0.0.0:3334') # Then do the usual things # ... return )ÚTuioMotionEventProviderÚTuio2dCurMotionEventÚTuio2dObjMotionEventé)ÚLogger)Úpartial)Údeque)ÚMotionEventProvider)ÚMotionEventFactory)Ú MotionEvent)Ú ShapeRectcspeZdZdZiZ‡fdd„Zedd„ƒZedd„ƒZedd „ƒZ d d „Z d d „Z dd„Z dd„Z dd„Z‡ZS)ragThe TUIO provider listens to a socket and handles some of the incoming OSC messages: * /tuio/2Dcur * /tuio/2Dobj You can easily extend the provider to handle new TUIO paths like so:: # Create a class to handle the new TUIO type/path # Replace NEWPATH with the pathname you want to handle class TuioNEWPATHMotionEvent(MotionEvent): def depack(self, args): # In this method, implement 'unpacking' for the received # arguments. you basically translate from TUIO args to Kivy # MotionEvent variables. If all you receive are x and y # values, you can do it like this: if len(args) == 2: self.sx, self.sy = args self.profile = ('pos', ) self.sy = 1 - self.sy super().depack(args) # Register it with the TUIO MotionEvent provider. # You obviously need to replace the PATH placeholders appropriately. TuioMotionEventProvider.register('/tuio/PATH', TuioNEWPATHMotionEvent) .. note:: The class name is of no technical importance. Your class will be associated with the path that you pass to the ``register()`` function. To keep things simple, you should name your class after the path that it handles, though. csætƒ ||¡| d¡}t|ƒdkrXt d¡t d¡dtd |¡ƒ}t |¡dS|d d¡}t|ƒdkr¦t d¡t d¡dtd |¡ƒ}t |¡dS|d d¡\|_|_ t |j ƒ|_ i|_ d|_ t ƒ|_i|_dS)Nú,rz-Tuio: Invalid configuration for TUIO providerz1Tuio: Format must be ip:port (eg. 127.0.0.1:3333)z#Tuio: Current configuration is <%s>ú:é)ÚsuperÚ__init__ÚsplitÚlenrÚerrorÚstrÚjoinÚipÚportÚintÚhandlersÚoscidrÚ tuio_event_qÚtouches)ÚselfÚdeviceÚargsÚerrZipport©Ú __class__©ú=/tmp/pip-unpacked-wheel-xzebddm3/kivy/input/providers/tuio.pyrZs*          z TuioMotionEventProvider.__init__cCs|tj|<dS)z.Register a new path to handle in TUIO providerN©rÚ __handlers__©ÚoscpathÚ classnamer#r#r$Úregisterqsz TuioMotionEventProvider.registercCs|tjkrtj|=dS)z:Unregister a path to stop handling it in the TUIO providerNr%r'r#r#r$Ú unregistervs z"TuioMotionEventProvider.unregistercKs&|tjkrtd|ƒ‚tj|f|ŽS)z%Create a touch event from a TUIO pathzUnknown %s touch path)rr&Ú Exception)r(Úkwargsr#r#r$Úcreate|s  zTuioMotionEventProvider.createcCs€zddlm}Wn tk r0t d¡‚YnX|ƒ|_}|j|j|jddt j D]"}i|j |<|  |t |j|ƒ¡qXdS)zStart the TUIO providerr)ÚOSCThreadServerz@Please install the oscpy python module to use the TUIO provider.T)ÚdefaultN)Z oscpy.serverr/Ú ImportErrorrÚinforÚlistenrrrr&rÚbindrÚ _osc_tuio_cb)rr/Zoscr(r#r#r$Ústartƒsÿ   zTuioMotionEventProvider.startcCs|j ¡dS)zStop the TUIO providerN)rZstop_all©rr#r#r$Ústop“szTuioMotionEventProvider.stopcCs8z|j ¡}Wntk r$YdSX| ||¡qdS)z4Update the TUIO provider (pop events from the queue)N)rÚpopÚ IndexErrorÚ_update)rÚ dispatch_fnÚvaluer#r#r$Úupdate—s zTuioMotionEventProvider.updatecGs|j |||g¡dS©N)rÚ appendleft)rr(Úaddressrr#r#r$r5£sz$TuioMotionEventProvider._osc_tuio_cbc Cs|\}}}|dkrdS|dkr”|d}||j|krjtj||j||dd…ƒ}||j||<|d|ƒn*|j||}| |dd…¡|d|ƒ|dkrþ|}g} |j|D],}||kr®|j||}|| kr®|  |¡q®| D]}|d|ƒ|j||j=qàdS) N)óaliveósetrCréÚbeginr>rBÚend)rrr&rÚmoveÚappendÚid) rr<r=r(ÚcommandrrIÚtouchZalivesZ to_deleter#r#r$r;¦s6  ÿ    zTuioMotionEventProvider._update)Ú__name__Ú __module__Ú __qualname__Ú__doc__r&rÚ staticmethodr*r+r.r6r8r>r5r;Ú __classcell__r#r#r!r$r4s#     rcsleZdZdZdZ‡fdd„Zedd„ƒZedd„ƒZedd„ƒZ ed d„ƒZ ed d„ƒZ ed d„ƒZ ‡Z S) ÚTuioMotionEventa´Abstraction for TUIO touches/fiducials.
