[Jython-users] More on problem with subclassing Java class

[Kent J. <kjo...@tr...>]

Here is a complete test case. When using the first showData in 
MyCallback, it works. With the second callback (as below) it gives

Traceback (innermost last):
   File "<console>", line 1, in ?
   File "./Project/Test.py", line 12, in ?
TypeError: showData() takes at least 3 arguments (2 given)

Note: If it matters, I am running this from inside the command 
interpreter using execfile('Test.py', globals()) (because I am on a 
Mac, no command line).

// Test.java

package test;

public class Test
{
	public static class Data {
		public String name;
		public int value;
	}

	public static class Callback {
		public void showData(Data inData) {
			showData(inData.name, inData.value);
		}

		public void showData(String inName, int inValue)
		{ /* empty */ }
	}


	public static void testData(Callback inCallback)
	{
		Data data = new Data();
		data.name = "This is a test";
		data.value = 3;
		inCallback.showData(data);
	}

}


# Test.py

from test import Test

class MyCallback(Test.Callback):
#	def showData(self, inData):
#		print inData.name
#		print inData.value

	def showData(self, inName, inValue):
		print inName
		print inValue

Test.testData(MyCallback())
