Escape codes not working

[Steve]

Hi all,

Why is it that the statement:

Label l = new Label("This \n Test should work");

shows the label with a block (as in, square) character instead of the linefeed?

From the API doc of java.awt.Label:

"A label displays a single line of read-only text."

Have you tried carriage return (\r) or both \n and \r ?

Because it is not supported. Use a TextArea instead, or use Swing and
HTML in the label.

Because Label is not smart enough, or rather the underlying GUI is not
smart enough. To get that effect you need Swing JLabel and use HTML
and encode your linefeed as <br>

Label is defined to be one line, so this has nothing
to do with lack of smartness.
Don't use HTML; Google for "MultiLineLabel" instead.

Well, if you ask me, it would be a lot smarter for Label to support
multiline than not to.

Don't use HTML; Google for "MultiLineLabel" instead.

Why, when JLabel already does this anyway? Does MultiLineLabel do
something that JLabel can not?

Label is defined to be one line, so this has nothing
to do with lack of smartness.

But if you ponder WHY Label was defined that way, the reason is the
that Label is a heavyweight component. It is limited by what
heavyweight Label components in various GUIs can do. In general, they
are not smart enough to handle multiline labels. Thus, Java had to
limit Label to the lowest common denominator.

In Swing, JLabel is a lightweight component. It thus does not matter
what the underlying GUI does, so JLabel can even be smart enough to
render HTML or Images.
