Hi!Randy and other ensusiasts:
Can anyone please guide me to use the ButtonBorder? I try to use it just
as following:
label1.setBorder(new ButtonBorder());
but I am getting an Exception.
I searched in the newsgroup and found that some people had asked the
same question as me.Randy answered that it requires a Button figure.But
how can I get the figure? Can anyone please point me to an example on
the same?
Thanks a lot!

Thanks for Andreas' answer!Now I understand where I was wrong.
But what I am trying to do is to write an editor just like the SWT
Designer.I want to use the draw2d control figures as my view(like the
buttons,textfields...).And I just need an static editable image of the
button(the display text can be changed by the user)rather than a real
clickable one.But the draw2d button do not provide any methods to change
these properties of the figures after constructed.So I asked this
question here a few days ago,Randy suggested me to use a label figure
with a button border.If I cannot achieve my goal by this method,could
anyone point me another way?
Each time when I asked a question here I received many enthusiasm
replys,and they helped me a lot.I really appreciated these friends and
people,if any of you come to china please contact me!
Best Wishes!
