The widget identified by child has been added to the receiver.
This method is public not because you can call it, but because
it can be useful to override it, not forgetting the call to
basicAddChild, to perform some initialization on the children
just added. Answer the new child.
create
Make the receiver able to respond to its widget protocol.
This method is public not because you can call it, but because
it can be useful to override it, not forgetting the call to
super, to perform some initialization on the primitive
widget just created; for an example of this, see the
implementation of BButtonLike.
initialize: parentWidget
This is called by #new: to initialize the widget (as the name
says...). The default implementation calls all the other
methods in the `customization' protocol and some private
ones that take care of making the receiver's status consistent,
so you should usually call it instead of doing everything by
hand. This method is public not because you can call it, but
because it might be useful to override it. Always answer the
receiver.
setInitialSize
This is called by #initialize: to set the widget's initial size.
The whole area is occupied by default. This method is public
not because you can call it, but because it can be useful to
override it.
