Ok I see! Thanks a lot.
invalidate() is to be called after or before ? and for add or remove ?
Should I do write like:
jPanel1.invalidate();
jPanel1.removeAll();
jPanel1.add(new JLabel("Hello"));
jPanel1.validate();
?
Because I tried this above, and it's nearly ok, but not totally. Indeed, it seems
to
refresh well about the jPanel1.add(...), but not about the jPanel1.removeAll()
