NSSelector question

Hello:

I'm new to xCode (I'm using v. 1.1) and would appreciate any suggestions on this problem.

CONTEXT: I'm trying to get a certain method (tableRowDoubleClicked) to run when an uneditable row in an NSTableView is clicked. I am writing this project in Java.

IMMEDIATE PROBLEM: my program doesn't seem to recognise the method I've created. Specifically, NSSelector.implementedByClass is returning false for the method in question.

QUESTION: Is it enough to define the method and then create a selector to it, or do you need to somehow register it before it will be seen? What have I done wrong here or left out?

Here is the code I'm using, from a custom class definition:

==============================
    private NSTableView		fileNames;			/* IBOutlet */
    public  NSSelector 		       theSelector;

theSelector = new NSSelector("tableRowDoubleClicked", new Class[] {null});

fileNames.setTarget(null);
fileNames.setDoubleAction(theSelector);
System.out.println(theSelector.implementedByClass(DirectoryBrowser.class ));
System.out.println(theSelector.name());
System.out.println(fileNames.target());
System.out.println(fileNames.doubleAction());
try{
System.out.println(theSelector.methodOnClass(DirectoryBrowser.class));
}
catch(NoSuchMethodException e) {
System.out.println("noSuchMethod");
}
=================================

and here is the output:


false
tableRowDoubleClicked
null
NSObjectiveCSelector tableRowDoubleClicked:
noSuchMethod


I would have expected the first line to be true since I have a method defined:

	
	public void tableRowDoubleClicked() { /* IBAction */
System.out.println("Double-clicked!");
	}

Also, I'm a bit concerned that the fourth println indicates an NSObjectiveCSelector instead of an NSSelector, but I think I've followed Apple's examples, so I'm not sure how else to do it.


Thanks in advance for any help or ideas!
