Is Swing good for game development?
Swing is fine for simple games, but if you really care about performance of redrawing, you should probably take a look at one of the frameworks based on OpenGL. Examples: http://www.lwjgl.org/ – quite a low level library but very fast.
Is Swing multithreaded?
This means that most Swing components are, technically, not threadsafe for multithreaded applications. Now don’t panic: it’s not as bad as it sounds because there is a plan. All event processing in AWT/Swing is handled by a single system thread using a single system event queue.
Does Java Swing use threads?
Like any other program running on the Java platform, a Swing program can create additional threads and thread pools, using the tools described in the Concurrency lesson. But for basic Swing programs the threads described here are sufficient. This lesson discusses each of the three kinds of threads in turn.
What is Swing thread?
Java Practices->Swing threads. Swing threads. Event Dispatch Thread. In a Swing application, most of the processing takes place in a single, special thread called the event dispatch thread (EDT). This thread becomes active after a component becomes realized: either pack , show , or setVisible(true) has been called.
What is SwingUtilities invokeLater?
An invokeLater() method is a static method of the SwingUtilities class and it can be used to perform a task asynchronously in the AWT Event dispatcher thread. The SwingUtilities. invokeLater() method works like SwingUtilities. invokeAndWait() except that it puts the request on the event queue and returns immediately.
What is SwingUtilities invokeLater new runnable ()?
SwingUtilities class has two useful function to help with GUI rendering task: 1) invokeLater(Runnable):Causes doRun. run() to be executed asynchronously on the AWT event dispatching thread(EDT). This will happen after all pending AWT events have been processed, as is described above.
Which Swing methods are thread safe?
Event Dispatch Thread (EDT) Only thread-safe methods can be safely invoked from any thread. Since most of the Swing object methods are not thread-safe, they can be invoked from a single thread, the EDT.
What is EDT thread in Swing?
The event dispatching thread (EDT) is a background thread used in Java to process events from the Abstract Window Toolkit (AWT) graphical user interface event queue. Updating visible components from other threads is the source of many common bugs in Java programs that use Swing.
Are all Swing components thread safe?
The Java Swing components can only be accessed from the Event Dispatch Thread (EDT) once a component is available for painting onscreen. Only thread-safe methods can be safely invoked from any thread. Since most of the Swing object methods are not thread-safe, they can be invoked from a single thread, the EDT.
What are differences between Swing and AWT?
Difference between AWT and Swing Java swing components are platform-independent. AWT components are heavyweight. Swing components are lightweight. AWT doesn’t support pluggable look and feel.
