Is there a method to return the position of the character in the JTextField. What I mean by that is if I have a JTextField with some values in it. For example, the field contains value ABCDEFJ. The user decides to put the cursor right after the character 'C' to enter a new value. Is there a method to get position where he enters the new character. In this example, that would return a 3.
JTextField.getCaretPosition()
JTextField.setCaretPosition(int pos)
Try getting use of CaretListener
interface:
public class A extends JFrame implements CaretListener
{
//Assume you have a text field.
public A()
{
JTextField field = new JTextField("bla bla");
field.addCaretListener(this);
.....
}
public void caretUpdate(CaretEvent e)
{
int index = e.getDot();
.....
}
}
getDot()
method of CaretEvent
class returns the result you desire, you can assign it to a global variable to use later on.
Here's your answer:

Use an ActionListener to wait for an action. When the user types something, find the caret position.
