Examples of org.eclipse.swt.widgets.Text.addVerifyListener()

org.eclipse.swt.widgets.Text.addVerifyListener()
Adds the listener to the collection of listeners who will be notified when the receiver's text is verified, by sending it one of the messages defined in the VerifyListener interface. @param listener the listener which should be notified @exception IllegalArgumentException
- ERROR_NULL_ARGUMENT - if the listener is null
@exception SWTException
- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
@see VerifyListener @see #removeVerifyListener
