I'm new for Processing and trying to make simple sketch using GTextField with G4P (GUI sketch was built by gui builder). Could someone please write short example of sketch with CHANGE event?
So, I need two text fields and want to calculate some expression using first field and resulting to second field, but want to make real-time calculating during first filed typing (for example, textField2=textField1*3.1415). I think, I have to use CHANGE event to react typing, but don't know how.
