GUI problem when call another class

[doha786]

hi,
here is the GUI class, when i click the Button its calling a method from different class and show Results in TextArea correctly.

public class MainGui extends JFrame implements ActionListener
{
JButton myButton = new JButton("Button");
JTextArea txtArea = new JTextArea("");
JTextField txtField=new JTextField();
..
..
  public MainGui()
  {
..
..
  }
 
public void actionPerformed(ActionEvent e)
  {
    if (e.getSource() == myButton)

{ SearchCompare sc= new SearchCompare();
txtArea.setText(sc.process());}

Here is the method in 'SearchCompare' class that works as a small search engine....

public class SearchCompare{ 
..
public String process(){
String showResult="";
...
...
[B]String searchName="abc"; [/B]

for (String found: names.keySet()) {
File file = names.get(found); 
double compare = SearchCompareBig.LCS(found, searchName);
showResult+=found+"\t"+compare+"\t"+file.getName()+"\n";
}
 
return showResult; 
}

now, i want this 'searchName' String will get from TextField of MainGui and whatever the output generates will show results in TextArea of MainGui.

i made like this:

//String searchName="abc";
MainGui myGui=new MainGui();
String searchName=myGui.txtField.getText();

no error but no ouput in TextArea....
where should i change the code pls help...

Change this

public String process(){

to this

public String process(String searchName){

and pass the contents of the textfield.
