Called when the user presses a button in the NetLogo model.
Called when the user presses a button in the NetLogo model.
Note that the button may take some time to run and therefore may not pop back up until some
later. Use buttonStopped() if you need to know when the button's action has
completed.
Called when a button in the NetLogo model has finished running and pops back up.
Called when a button in the NetLogo model has finished running and pops back up.
The button may be a "once" button or a "forever" button. If it is a "once" button, it pops back up automatically when its action is completed. If it is a "forever" button, it will pop back up when clicked for a second time by the user. (Some forever buttons may also pop back up automatically, if the model is written that way.)

A host application should implement this interface in order to be notified of events occurring within NetLogo. Its methods are called by NetLogoListenerManager when these events occur. The events are typically user actions, but may also be triggered programmatically by the model.
