SwingUtilities.invokeLater

Question

My question is related to SwingUtilities.invokeLater. When should I use it? Do I have to use each time I need to update the GUI components? What does it exactly

Answer 1

Most user-initiated events (clicks, keyboard) will already be on the EDT so you won't have to use SwingUtilities for that. That covers a lot of cases, except for your main() thread and worker threads that update the EDT.
