help please
i have 20 textfields & buttons.
private JTextField[] myTextFields;
private JButton[] editButtons;
........
myTextFields =new JTextField[getListSize()];//getListSize returns the size of 20
editButtons =new JButton[getListSize()];
for(int index=0; index < getListSize(); index++){
myTextFields[index] =new JTextField(30);
editButtons[index] =new JButton("edit");
}
i am displaying these textfields & buttons as pairs in each line. I have 20 filenames displayed in each textfield. Now when i click on particular textfields adjacent edit button, then it should open that respective file. Now i am confused on how to identify as to which textfields ajacent edit button is clicked.
please help me

One of those buttons fires an ActionEvent which is passed to your
actionPerformed method in your ActionListener. The ActionEvent can
tell you the 'source' where the event came from:JButton button= (JButton)event.getSource();
for (int i= 0; i < editButtons.length; i++)
if (editButtons[i] == button)
// button number i was pressed
kind regards,
