Hi can we take input for a URL using swing? supposed im taking input
Name:"Bobby" in the text box/Text Field
and i use the getText() method to get the text from the text box...
and print "You have entered Bobby"

It works fine for me. Please show us a small program that demonstrates how it isn't working.

This is a portion of the Code..im new so it might look really lame

//create the components
lbl1=new JLabel("Enter the URL :");
jtf = new JTextField(20);
lbl2=new JLabel();
jbtn1=new JButton("Submit");
jta1=new JTextArea(20,40);
jsp1=new JScrollPane(jta1);
jbtn1.addActionListener(this);

// Add text field to content pane
contentPane.add(lbl1);
contentPane.add(jtf);
contentPane.add(jbtn1);
contentPane.add(lbl2);
contentPane.add(jsp1);

jbtn1.setToolTipText("Hi bianca");

this.setSize(600, 400);

// pack();
setVisible(true);
setDefaultCloseOperation(EXIT_ON_CLOSE);

//end of UI design

String sourceLine;


// The URL address of the page to open.
url =jtf.getText().toString() ;

try{
URL address = new URL(url);

// Open the address and create a BufferedReader with the source code.

pageInput = new InputStreamReader(address.openStream());
source = new BufferedReader(pageInput);

it doesn't work and it seems as if im passing nothing in the text Field x_x

I think we need to see more. For instance, where are you calling this line?

Code:

---

url =jtf.getText().toString() ; // by the way, toString() is not needed as getText returns String

---

Is it in the actionPerformed method of an ActionListener?

Also, please read my signature link on using code tags -- thanks!

Much luck!

No its not in the actionPerformed method.I tried keeping it there but its still not taking the URL from the textfield.Im calling toString() because i've tried many things but its still not working.Can you please provide some sample code for taking a URL from a textfield and passing that URL to a BufferedReader ?

My guess is then that you're trying to read the contents of the JTextField when the GUI is starting up before any text has been added by the user. The usual way to get text from these critters is to do it on an event such as a button push (hence the use of an ActionListener) or on pressing enter when within the JTextField (again this uses an ActionListener).

All you need to do is get the String and my sample code to do this is no better than what is posted in the Java tutorials. I think that we still need to get a better understanding of what you're doing wrong in order to solve this.

Again, I suggest you get the JTextField's text from within the ActionListener of a JButton. Try that, and if it still doesn't work, please post your code (but please use code tags).

Luck!

it worked ^_^

Good deal and congrats!
