I would also add that in this case, it is essential to call a function
rather than just set the property - the button then has other work to
do (like repainting, maybe resizing).

In Delphi, as steve says, you can arrange that setting a property 
automatically calls a function. I java, that's no true. The property
'Label' itself has been protected specifically to force you to use the 
"setter" function which also does the other housekeeping.
