Limit JTextPane size

Hi,
I want to use a JTextPena for writing but I want to limit the size of the writable area.
Lets say I want to allow writing only in 3 rows. Anything over 3 rows will beep and not be written.
Do I have to use DefaultStyledDocument? and if so how?
thanks,
Edgar

only and only 3 rows ? is the user writing continusly in 3 rows or he is pressing enter to go to the next row ?

implementing limitation of how many characters the user can type would be easy :P

Hi glottis,
To limit the number of characters is easy as you said and I can do it using DocumentFilter class.
The problem is that I want to limit the JTextPane to a set number of lines (not necesarily lines seperated by pressing enter). Another problem is that I am using different types of font and font size.
Thanks,
Edgar

u have to look deeply in the textpane class and see how Java inserts string on new lines. maybe that way u can limit.
