I have my own class which derives from JTextPane. I want that the object of this class should divide his content on pages of given size. I am dividing on pages simply by drawing a line in proper place on paintComponent method.

Let's say that I write a letter and my pane has resized so that typed letter should on next page. I would like to resize my pane more to has the size of one more page. I know that I should write a ComponentListener and add some code in componentResize method but I can't explicity use setSize method because it generate another event and I will get exception. Thus, how can I do that properly?

However this is not what I want... – bakala12 Jul 23 '15 at 12:15
If you post a working sample it will make life easier :). I did a small experiment and the result is that you can `setSize` in `KeyListener` and just do normal painting in the `paintComponent` method. This seems to be working. – Dakshinamurthy Karra Jul 23 '15 at 13:35
@KDM: A `DocumentListener` might be more flexible. – trashgod Jul 23 '15 at 14:30
@trashgod: Not sure when it will be invoked. I guess after the keypress/repaint etc. is done. Without looking at JDK source, I think KeyListener is a better bet. – Dakshinamurthy Karra Jul 23 '15 at 14:58
May be it's better to define pagination like this http://java-sl.com/Pagination_In_JEditorPane.html – StanislavL Jul 24 '15 at 05:28
Wow, this pagination is pro :D However, is there any way to use it together with `HTMLDocument`? – bakala12 Jul 24 '15 at 06:55
Ok, I have it. This is a superb solution http://java-sl.com/JEditorPanePrinter.html Thanks to StanislavL – bakala12 Jul 24 '15 at 08:53
