The functions designed on the Function Builder can be attached to the available Infinity objects and triggered by the various events raised by these objects. You can add Script, Screen and Control functions to events as described below. There is also the additional global event GlobalExecute.
Each control has its own "canvas", onto which you can define a function for multiple events the control can raise. Thus, you can build an "action" function that can contain multiple code blocks for each of the events that can be triggered by the control it is attached to. E.g., for a Script control, Start, End and CodeCall event handlers can be defined in the same function to run different chunks of code. By having a single function per control you can see all the code associated with it at a glance.
Images of these events can be seen on the Events topic .
