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

org.eclipse.swt.widgets.Display.timerExec()
Causes the run() method of the runnable to be invoked by the user-interface thread after the specified number of milliseconds have elapsed. If milliseconds is less than zero, the runnable is not executed.
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 milliseconds the delay before running the runnable @param runnable code to run on the user-interface thread @exception IllegalArgumentException
- ERROR_NULL_ARGUMENT - if the runnable is null
@exception SWTException
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
- ERROR_DEVICE_DISPOSED - if the receiver has been disposed
@see #asyncExec

                // this one will be called in UI thread ASAP and allow us to leave
