SwingUtilities is a class present in the javax.swing package library in Java. It provides a set of helpful methods for working with Swing components and threads. The SwingUtilities class allows developers to execute code on the event dispatch thread, or EDT, which is the thread responsible for managing GUI components.
Example 1: InvokeLater The SwingUtilities invokeLater method is used to execute code on the EDT thread. This is important for updating GUI components, as it helps to prevent concurrency issues. In the following example, we use the invokeLater method to update a text field in a Swing application:
Example 2: IsEventDispatchThread The isEventDispatchThread method is used to determine whether the current thread is the EDT thread. This can be useful for determining whether certain code should be executed on the EDT thread. In the following example, we check whether the current thread is the EDT thread before updating a label:
if (SwingUtilities.isEventDispatchThread()) { myLabel.setText("Updating on the EDT thread"); } else { SwingUtilities.invokeLater(() -> { myLabel.setText("Updating on the EDT thread"); }); }
Overall, the SwingUtilities class provides a set of useful methods for working with Swing components and threads. Its methods are used to perform actions on the EDT thread, update GUI components, and check whether a thread is the EDT thread.
