in the following program i try to set the spacebelow attribute - but it
doesn?t work; why?

and i want to insert the string "test" with an own component (see code). i
want to use insertComponent(new MyComponent()); and not insertString,
because i have to do some extra drawing (circle around the text).
how can i do, so that the inserted text has exactly the same attributes like
the text at the insertion position and the same baseline? the original text
has a lot of different styles.

thanks
