Called by the framework to determine if the field can accept focus.
Called by the framework when the field gains focus
called by the framework when the field loses focus
called when the pointing device clicks on a field that has focus
called to place the field in a "dirty" state so that it will be repainted
May I suggest that you purchase one of the very good beginners books on Blackberry development?

Hi bb_develop and welcome to the forums.
I would agree with RexDoug, a book may well help you, because you will find that some of the API explanations are brief. I have to say that the OS 5.0 API documentation is lot better than the older ones, so if you are looking for an explanation, look there first.
Good luck with your developing.

If you are a beginner to Java you will find this all very difficult. In that case I would recommend that you buy a simple Java book, any Java book will do. There is no book that takes you from not programming to programming Java on Blackberry. you must learn to program Java, then learn BlackBerry.
