How to avoid firing actionlistener event of JComboBox when an item is get added into it dynamically in java?

Question

I need your suggestions and guidence on following task.

I have a frame which has two JComboBoxes supposed they are named combo1 and combo2, a JTable and other compon

Answer 1

What i do instead of adding and removing action listeners i have a boolean variable in my action listeners that is true if it has to allow the action through or false if it has to block it.

I then set it to false when i do some changes that will fire off the action listener

JComboBox test = new JComboBox();
test.addActionListener(new ActionListener()
{
  @Override
  public void actionPerformed(ActionEvent e)
  {
    if(testActionListenerActive)
    {
      //runn your stuff here
    }
  }
});

//then when i want to update something where i want to ignore all action evetns:
testActionListenerActive = false;
//do stuff here like add 

SwingUtilities.invokeLater(() -> testActionListenerActive = false);
//and now it is back enabled again
//The reason behind the invoke later is so that if any event was popped onto the awt queue 
//it will not be processed and only events that where inserted after the enable 
//event will get processed.
