selectRange() is very slow

[ghost]

Since there is no way of scrolling at the moment (see bug #98), I am using a workaround os selectRange(index,index). However, this is very slow.

In a 4800 lines file with 3 different styles per line, it takes more than 6 seconds to perform the operation on a Intel core i7 machine.

    long nanoTime = System.nanoTime();
    codeArea.selectRange(codeArea.getText().length(), codeArea.getText().length());
    System.out.println(System.nanoTime() - nanoTime);

Note that codeArea.getText() involves concatenating all the paragraphs. If you have 4800 lines, each containing 3 segments of styled text, that means concatenating 19200 strings (the 3 segments + newline per paragraph). Although this could (and should) be improved, if you don't need the actual text, but only its length, use codeArea.getLength() instead. Let me know whether and how much this improved your situation.

Thanks fo the reply. In fact I don't need the text at this time. Unfortunately it does not really improve performance (6.4 sec --> 6.3 sec).

This is fixed in version 0.6.2. Sorry it took so long.
