Examples of org.eclipse.swt.widgets.Display.asyncExec()

org.eclipse.swt.widgets.Display.asyncExec()
Causes the run() method of the runnable to be invoked by the user-interface thread at the next reasonable opportunity. The caller of this method continues to run in parallel, and is not notified when the runnable has completed. Specifying null as the runnable simply wakes the user-interface thread when run.
Note that at the time the runnable is invoked, widgets that have the receiver as their display may have been disposed. Therefore, it is necessary to check for this case inside the runnable before accessing the widget.
@param runnable code to run on the user-interface thread or null @exception SWTException
- ERROR_DEVICE_DISPOSED - if the receiver has been disposed
@see #syncExec
