Adding input?

[dudeishfish]

Hey Everyone!

After using Devshed (possibly the worst forum I have ever encountered) I have come here with my questions and answers about Java, Python, VB, Basic C++, HTML, Game Maker, and Uni-Gasp. So, greetings!

On to the question: I have been working on a Text editor a little bit, and hit a dead halt. I can not figure out how to import text into my program. I have what I thought would work in my code, but it just doesn't seem to work! Every time I try to compile, it gives an error: "file is not public in java.awt.filedi alog; cannot be accessed from outside package". Here is the code:

Why don't you make your FileDialog public on line 16 and see what happens. Remember that if you don't specify an access modifier for an atrribute, protected access is assumed.

[dudeishfish]

Sorry, but I am stupid :( How do you make it public?

[r035198x]

Sorry, but I am stupid :( How do you make it public?

prefix the declaration with the word public?

[dudeishfish]

I assume you mean:

 public FileDialog obj = new FileDialog(this);

I didn't work. :(
Am I doing something wrong?

[r035198x]

When you say it didn't work you mean you got the same error message?

[dudeishfish]

Yep. The same error message. It didn't seem to do anything.

[JosAH]

Yep. The same error message. It didn't seem to do anything.

You can't just stick in 'public' somewhere because someone told you so and hope
for the best. A public method must be public for a reason, i.e. it must've been designed
that way and maybe that method turns up to be part of an interface implemented by
your class.

For now your class doesn't even compile; you should read what the compiler has
told you and fix the text of your source code. Just typing in what other people suggest
you without you knowing *what* you're doing is not going to help you.

kind regards,

Jos

Thats kind of why I posted this question-because I have no idea what to do. By telling me that I did it wrong and should do it myself, you helped me in no way. I still do not know what to do to make it work.

[dudeishfish]

Sorry about double post.

I tinkered with the code for a little while and got this:

            open.setAccelerator(
            KeyStroke.getKeyStroke(KeyEvent.VK_O, Event.CTRL_MASK));
            open.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent e) {
 
                obj.setMode(FileDialog.LOAD);
                String filename = "Untitled";
                obj.show();
                filename = obj.getDirectory()+obj.getFile();
                setTitle(filename);
                   try {
              BufferedReader reader = new BufferedReader (new InputStreamReader( new FileInputStream (new File (filename))));
              String firstLine = reader.readLine ();
              System.out.println ("The first line is: " + firstLine);
              a.setText(firstLine);
            }
              catch( Exception f) {f.printStackTrace();}
 
 
 
                }
            });
