 */// w w w . j av  a 2 s .  c o m
public void setText(String what) {
    // Remove all highlights, since these will all end up at the start of the
    // text otherwise. Preserving them is tricky, so better just remove them.
    textarea.removeAllLineHighlights();
    // Set the caret update policy to NEVER_UPDATE while completely replacing
    // the current text. Normally, the caret tracks inserts and deletions, but
    // replacing the entire text will always make the caret end up at the end,
    // which isn't really useful. With NEVER_UPDATE, the caret will just keep
    // its absolute position (number of characters from the start), which isn't
    // always perfect, but the best we can do without making a diff of the old
    // and new text and some guesswork.
    // Note that we cannot use textarea.setText() here, since that first removes
    // text and then inserts the new text. Even with NEVER_UPDATE, the caret
    // always makes sure to stay valid, so first removing all text makes it
    // reset to 0. Also note that simply saving and restoring the caret position
    // will work, but then the scroll position might change in response to the
    // caret position.
