Examples of org.eclipse.swt.events.ModifyListener

org.eclipse.swt.events.ModifyListener
Classes which implement this interface provide a method that deals with the events that are generated when text is modified.
After creating an instance of a class that implements this interface it can be added to a text widget using the addModifyListener method and removed using the removeModifyListener method. When the text is modified, the modifyText method will be invoked.
