如何检查事件是由模拟操作还是手动执行的操作触发的

Question

I want to know is it possible to check an event is generated by another event or manually generated event.In brief suppose we click any button, inside action performed if we write code to generate another event on some other component, how can i get to know which is generated by which. How can differentiate whether manual or simulated based on event generated????

public void actionPerformed(ActionEvent ae) { JComponent source =(JComponent) ae.getSource(); //this is action for manually clicked event. if(source == button1) { //this is to generate simulated event. exitButton.doClick(); } //this is action for simulated event. else if (source == exitButton) { System.exit(0); } }

You could distinguish between your custom events and other events by checking their class type.

if (catchedEvent instanceof MyCustomEvent){}

If you have several custom events, you could set eventCode in MyCustomEvent class to indicate the event meaning.
