Hello everyone,
I want to extend ViewForm in order to add methods to enable the setting of
controls to the bottom left/center/right instead of just top
left/center/right. In the java doc it said this class is not intended to be
subclassed. Does this mean, do not subclass, or its not intended to be
subclassed but you can if you want to? Thanks
Chris

ViewForm is not intended to be subclassed. Since the methods you would need
to override to layout additional buttons are package protected, overriding
checkSubclass () will not help you.
