The addEventType method is a useful method provided by the Java Configuration class, which allows developers to add a custom event type to a JavaFX application. This method is commonly used when developers want to create and handle their own unique events in JavaFX.
Here is an example of how to use addEventType() in JavaFX:
// Define a custom event type. EventType MY_CUSTOM_EVENT_TYPE = new EventType<>("MY_CUSTOM_EVENT_TYPE");
// Add the custom event type to the application. Configuration.getEventBus().addEventType(MY_CUSTOM_EVENT_TYPE);
// Handle the custom event type in a JavaFX event handler. EventHandler myCustomEventHandler = e -> { System.out.println("My custom event was fired!"); };
// Register the custom event handler with the custom event type. Configuration.getEventBus().addEventHandler(MY_CUSTOM_EVENT_TYPE, myCustomEventHandler);
In this example, we first import the necessary libraries for working with events in JavaFX. We then define a custom event type, MY_CUSTOM_EVENT_TYPE, which is a subclass of the javafx.event.EventType class. We then add this custom event type to the application using the addEventType() method provided by the Configuration class.
We then define an event handler for the custom event type, which simply prints a message to the console when the event is fired. Finally, we register the custom event handler with the custom event type using the addEventHandler() method provided by the Configuration class.
The package library used in this example is the javafx.event package, which is part of the JavaFX library for building user interfaces.
