Question

I’m not really sure how to go about this and I don’t think I’m looking in the right direction.

I have a swing form that contains quite a large number of fields and I want to save these fields in a secondary Save class when the user presses the Save button.

Is there a way I can pass the entire contents of the Swing form to the Save Class?

btnSave.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent arg0) {
            SaveMap.MapSave(???);
        }
    });

Then:

public class SaveMap {  
    public static boolean MapSave(???) {
      // save stuff
    }
}

Not easily. It also depends on what you are trying to save.

Difference controls will provide different data.

Basically, I would create some kind of “builder” that could that could the “name” of the field and either the control itself or it’s value…

Savable savable = new SaveBuilder.add("userName", userNameField).add("password", passwordField);
SaveMap.MapSave(savable);

This has the benifit of allowing to extract the information you need in the way you need it…

or

Savable savable = new SaveBuilder.add("userName", userNameField.getText()).add("password", passwordField.getPassword());
SaveMap.MapSave(savable);

Obviously, the SaveMap would need to be able to extract the property names and values.
