Answer 1

SWT implements single threaded UI model. In this model, only the UI-thread can invoke UI operations. If you try and access an SWT object from outside the UI-thread, you get the exception "org.eclipse.swt.SWTException: Invalid thread access". So to allow other threads to perform operations on objects belonging to the UI-thread, SWT provides syncExec and asyncExec methods.
