Use documentlistener to get source of which text field is changed

[Andolph23]

private class myListener implements DocumentListener
{
public void insertUpdate(DocumentEvent e)
{
// Hours
if(e.getSource() == hours)
{
String hours_text = hours.getText();
System.out.println(hours_text);
}
}
}


I need to be able to tell which text field the user inserts text into, so i used e.getSource() in an if statement to find if it was the hours text field. When I compiled I got an error saying could not find symbol.

Possibly this is a scope issue and likely depending on the code that you're not showing us, but I can't really say for sure. Is hours declared in the constructor making it invisible to this inner private class?

Bottom line: we really need more information to be able to give accurate help. Also, if you use code tags when posting code here, it will be a lot easier to read your code.

Que tenga mucha suerte!

Even when you fix the compile problem is won't work, because the source is the Document, not the text field.

So you need to pass in the text field as a paramenter to your custom class when you create it.

Also, use the "Code tags" when you post code so the code you post retains its formatting and is readable.

I was able to solve the problem using this code

private class myListener implements DocumentListener
	{
		public void insertUpdate(DocumentEvent e)
		{
			if(e.getDocument() == hours.getDocument())
			{
				System.out.println("Hello");
			}

		}

but I would like to know the idea Camickr had of passing the textfield as a parameter to my custom class would work out of curiosity. I tried to use your suggestion but was having trouble.
