I have a JPanel full of JTextFields…
JavaScript
x
for (int i=0; i<maxPoints; i++) {
JTextField textField = new JTextField();
points.add(textField);
}
How do I later get the JTextFields in that JPanel? Like if I want their values with
JavaScript
TextField.getText();
Thanks

Well bear in mind they didn’t get there by them selves ( I think a read some questions about dynamically creating these panels at runtime )
In the answers posted there, someone said you should kept reference to those textfields in an array. That’s exactly what you need here:
JavaScript
List<JTextField> list = new ArrayLists<JTextField>();
// your code...
for (int i=0; i<maxPoints; i++) {
JTextField textField = new JTextField();
points.add(textField);
list.add( textField ); // keep a reference to those fields.
}
// Later
JavaScript
for( JTextField f : list ) {
System.out.println( f.getText() ) ;
}
Wasn’t that easy?
Just remember to keep these kinds of artifacts ( list ) as private as possible. They are for your control only, I don’t think they belong to the interface.
Let’s say you want to get the array of texts, instead of
JavaScript
public List<JTextField> getFields();
You should consider:
JavaScript
public List<String> getTexts(); // get them from the textfields ...
