public static void accessDisplayDuringStartup()This method allows threads spawned early in the workbench startup process to access the Display via the
Display.asyncExec(Runnable)
andDisplay.syncExec(Runnable)
methods. Without invoking this method from a given thread subsequent calls to the above Display methods will behave as follows:- runnables posted to
Display.asyncExec(Runnable)
will not be invoked until after the Workbench is fully restored. - calls made to
Display.syncExec(Runnable)
will block until the Workbench is fully restored.
This method MUST NOT be called from threads created by the workbench. If invoked from any thread owned by the Workbench this method will throw an
