Method Detail

runInDispatchThread

public static void runInDispatchThread(java.lang.Runnable runnable)

Run the runnable in EventDispatch Thread. If the current thread is EventDispatch, it will run immediately otherwise it will be queued in the DispatchThread The difference with VFSManager.runInAWTThread() method is that this one will not wait for IO Request before being executed

Parameters:

runnable - the runnable to run

runInDispatchThreadAndWait

public static void runInDispatchThreadAndWait(java.lang.Runnable runnable)

Runs the runnable in EDT through invokeLater, but returns only after the runnable is executed. This method is uninterruptible.

Note the difference from invokeAndWait. If current thread is not EDT and there are runnables queued in EDT:

• this method runs the runnable after them
• invokeAndWait runs the runnable before them

runInDispatchThreadNow

public static void runInDispatchThreadNow(java.lang.Runnable runnable)

Runs the runnable in EDT through invokeAndWait. Even if the thread gets interrupted, the call does not return until the runnable finishes (uninterruptible method).

This method uses EventQueue.invokeAndWait, so the following remark applies:

If you use invokeAndWait(), make sure that the thread that calls invokeAndWait() does not hold any locks that other threads might need while the call is occurring. From the article: Threads and Swing
