How to set the line spacing in a JtextPane?

Question

First of all, i set the JTextPane like this:

HTMLEditorKit editorKit = new HTMLEditorKit();
HTMLDocument document = (HTMLDocument) editorKit.createDefaultDoc         


        

Answer 1

When you call textPane.setParagraphAttributes(aSet, false); it tries to apply line spacing to selection but nothing is selected

Call it another way

document.setParagraphAttributes(0, document.getLength(), attr, replace);
