I have added one
which is finally inside
Now based on text/lines inside
I want that scrollbars must come only if lines are greater than 3
if lines are less than 3 then it should not show scroll bars
I tried textArea.getLineCount() method but in every case it is returning only 1 as output even if lines are more than 1
In short my problem is that I want to know number of lines a textarea by using which I will set preffered size to
on which I am putting

has a constructor where you can define the row and column count.
What have you set for setLineWrap and setWrapStyleWord? These booleans will affect the getLineCount
