I created a little addon called ofxCallback. I use it for event handling / callback / signal slots.

Currently I’m still testing it but it seems very usefull to me. As soon as it’s ‘stable’ I will post it here on the forum.

Take care,

nice to hear! can you tell us anything about how it technical works yet?
does it use some pattern, libsigc++, …?

Look forward to this could really be helpful for ofxParameterUI… I am still having some issues with getting slider or button functions to access the main testApp.cpp variables…
