Hi there,

I've written a little OSC controller for millumin.
All my GUI & Osc sending works as expected. All calls made directly to the button Handler work fine, and I can display Text, shapes, etc...

I'm also wanting to listen to touch OSC on port 5001, and once the osc message correspond to specific parametre it trigger a series of action.
-> Trigger a button event (so i can reuse the same code as if i had clicked on the UI).
-> Send an OSC message.

Now both ways of doing that , works, as far as getting a feedback on the console or sending an OSC message to the app.

My Problem is:

None of these method allow me to draw anything in the processing app. I wanting to display some Text saying what is the last button press.
Calling the same button function / event handlers from the Osc event handlers, It Prints to console, send OSC, but won't draw anything.

Just wondering what am I doing wrong ? As i can verify that the whole If Statement gets executed, but none of the draw related commands works ( fill(); rect(); text(); background(); )

See Code Below:
