Wire Event Listeners
To wire an event listener, all you need is to declare a method with the event name. The method could have an optional argument for the event received. For example,
public void onChange(InputEvent event) {
//it will be wired and called when onChange is received.
}
public void onMove() {
//wired and called too, but no pass of the event
}
Wire Event Listeners Targeting Fellows
To wire a listener for an event targeting one of fellow, you could append the fellow's ID with a separator, $[1]. For example,
public void onClick$btn1() {
//Called when the fellow named btn1 is clicked
}
public void onChange$inp(InputEvent event) {
//Called when the fellow named inp's value is changed
}
- ↑ You could change the separator, if you want, by calling GenericForwardComposer.GenericForwardComposer(char, boolean, boolean) explicitly.
