Hello!
I have a Figure and would like to add some text in it, which should be
word-wrapped so that it fills the Rectangle from getBounds(). First I tried
to add a Label to my Figure, but the text is not wrapped. So I looked in the
Javadoc and found the class TextFlow, which fits my needs "An inline flow
that renders a sting of text across one or more lines.".
Now my problem: Simply instanciating and add()-ing it to my figure, gives me
a NullPointerException, so I guess the warning "It does not provide a
FlowContext" has probably something to do with it.
My code snippet and the full error message is below, does anybody know how
to do this?
Thank you very much in advance,
Martin
public MartinsFigure() {
TextFlow tf = new TextFlow("WRAPME WRAPME WRAPME");
this.add(tf);
}

FlowPage is the only figure that does not have the restriction, so place a
TextFlow inside a FlowPage.

Thank you for the quick response, this worked out well. But although it is
is showing in one line "WRAPME ", now, it is still not word-wrapping the
text. My new code snippet is below. I checked the bounds Rectangle with the
debugger and it is (height = 36, width = 64) for all three IFigures
(MartinsFigure, tf, fp), so that the text should actually get wrapped.
public MartinsFigure() {}
Thank you, Martin
