Subscribing to events

Subscribe to any .NET event with Javonet. Event subscription works the same way as listening Java events. The performance of event subscription is extremely high and allows you to interact with .NET code like it was native Java code. When the event occurs, your Java listener callback is called in a separate thread.
The simplest way to subscribe an event is to use an anonymous Java class.

Assuming we have a custom .NET Framework DLL with the following class inside:

namespace TestClass
{
	public class TestClass
	{
		public TestClass() { }

		namespace TestNamespace
		{
			public delegate void EventExampleHandler(object sender, string e);
		
			public class EventExample
			{
				public event EventExampleHandler SampleEvent;
		
				public void EventInvoke()
				{
					if (SampleEvent != null)
						SampleEvent(this, "Called from .NET!");
				}
			}
		}
		
	}
}
namespace TestNamespace
{
	public delegate void EventExampleHandler(object sender, string e);

	public class EventExample
	{
		public event EventExampleHandler SampleEvent;

		public void EventInvoke()
		{
			if (SampleEvent != null)
				SampleEvent(this, "Called from .NET!");
		}
	}
}

The anonymous class should implement special INEventListener interface to subscribe to .NET event.

Using .NET standard library elements

To create a .NET button and listen for a "Click" event:

The anonymous class should implement special INEventListener interface. Alternatively you can write a separate class as the event listener by extending NEventListener and overriding the eventOccurred method, or by implementing the ((INEventListener)) interface.
