Hi all,
I run into this problem:
I want to display a thumbnail of a figure which contains some text. I use
the StickyNoteFigure of the logic example as the figure to display in the
thumbnail.
Here is the code:
LightweightSystem lws = new LightweightSystem(overview); // overview is some
canvas
Thumbnail thumbnail = new Thumbnail();
StickyNoteFigure fig = new StickyNoteFigure();
fig.setText("The text to display");
fig.setBounds(new Rectangle(0, 0 , 300, 200));
thumbnail.setSource(fig);
lws.setContents(thumbnail);
If I run the code, I can see the yellow figure but it is empty. No text is
displayed. I don't know why. Any idea?
Thanks,
Alain

That's because the StickyNoteFigure doesn't exist anywhere, except in
memory. It's not in a lightweight system, doesn't have a parent or an
update manager or a font, and is never laid out or painted.
