SWT StyledText and Paragraph Spacing

Question

StyledText.setLineSpacing() allows line spacing, where each line (whether wrapped or following a carriage return) is separated from its predecessor.

Is there a way to set paragraph spacing, where wrapped lines sit together normally, but a carriage return inserts extra space?

(I want the final result to look much like this question, but without pressing enter twice between paragraphs.)

I am using both a StyledTextContent and a LineStyleListener. Ideally, I'd like to set paragraph spacing on each paragraph via the LineStyleListener, but I would settle for a document-wide solution...

Answer 1

I think you're going to have to modify the text itself as you write it to and read it from the StyledText.

Basically, you want to replace a single line feed with a double line feed when you setText, and replace a double line feed with a single line feed when you getText.

You'll also have to write a VerifyKeyListener, that replaces a single line feed with a double line feed.

System.getProperty("line.separator") will be helpful, although your file line feed might not match your system line separator.
