I was trying to set default focus to a textfield which was placed in a joptionpane, but it wast working with the following code

cvendor.requestFocus();

whereas the same code worked perfectly when the textfield was placed in a jpanel. On research i found that the default focus in a joptionpane is always on the OK button and it cannot be changed statically, it can only b changed during runtime using the Runnable interface. Here is the code that did the trick

javax.swing.SwingUtilities.invokeLater(new Runnable() {//<—–add
public void run() { cvendor.requestFocus(); }});//<—-add
nn=JOptionPane.showConfirmDialog(null,Jop,”Please enter details”,JOptionPane.CANCEL_OPTION,JOptionPane.QUESTION_MESSAGE);

kool na………..
