Provides a set of "lightweight" (all-Java language) components that, to the maximum degree possible, work the same on all platforms. For a programmer's guide to using these components, see Creating a GUI with JFC/Swing, a trail in The Java Tutorial. For other resources, see Related Documentation.
Typical Swing applications do processing in response to an event
generated from a user gesture. For example, clicking on a JButton
notifies all ActionListeners
added to the JButton
. As all events generated from a user gesture are
dispatched on the event dispatching thread, most developers are not
impacted by the restriction.
Where the impact lies, however, is in constructing and showing a
Swing application. Calls to an application's main
method,
or methods in Applet
, are not invoked on the event
dispatching thread. As such, care must be taken to transfer control
to the event dispatching thread when constructing and showing an
application or applet. The preferred way to transfer control and begin
working with Swing is to use invokeLater
. The invokeLater
method schedules a Runnable
to be processed on
the event dispatching thread. The following two examples work equally
well for transferring control and starting up a Swing application:
import javax.swing.SwingUtilities; public class MyApp implements Runnable { public void run() { // Invoked on the event dispatching thread. // Construct and show GUI. } public static void main(String[] args) { SwingUtilities.invokeLater(new MyApp()); } }Or:
import javax.swing.SwingUtilities; public class MyApp { MyApp(String[] args) { // Invoked on the event dispatching thread. // Do any initialization here. } public void show() { // Show the UI. } public static void main(final String[] args) { // Schedule a job for the event-dispatching thread: // creating and showing this application's GUI. SwingUtilities.invokeLater(new Runnable() { public void run() { new MyApp(args).show(); } }); } }This restriction also applies to models attached to Swing components. For example, if a
TableModel
is attached to a JTable
, the TableModel
should only be modified on the
event dispatching thread. If you modify the model on a separate
thread you run the risk of exceptions and possible display
corruption.
As all events are delivered on the event dispatching thread, care must
be taken in event processing. In particular, a long running task, such
as network io or computational intensive processing, executed on the
event dispatching thread blocks the event dispatching thread from
dispatching any other events. While the event dispatching thread is
blocked the application is completely unresponsive to user
input. Refer to SwingWorker
for the preferred way to do such
processing when working with Swing.
More information on this topic can be found in the Swing tutorial, in particular the section on Concurrency in Swing.
