What is SwingUtilities.invokeLater
invokelater, java, swing, swingutilities
Solution
Nothing bad will happen if you're updating it from the EDT while following guidelines.
That is...
If invokeLater is called from the event dispatching thread -- for example, from a JButton's ActionListener -- the doRun.run() will still be deferred until all pending events have been processed.

If that isn't the case, `invokeLater()` is required.
It schedules a `Runnable` which will be executed on the EDT (event dispatching thread).

Possible Duplicate: What does SwingUtilities.invokeLater do? SwingUtilities.invokeLater I have seen this little piece of code hundreds of times: ``` public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); } ``` Now my question is: what does `invokeLater()` do? What kind of bad things will happen if I just create and show my GUI inside the main thread?
