protected void drawLine(int line, Graphics g, int x, int y) {
    // Set the colors
    JTextComponent host = (JTextComponent) getContainer();
    unselected = (host.isEnabled()) ? host.getForeground() : host.getDisabledTextColor();

    int p0 = element.getStartOffset();
    int p1 = element.getEndOffset() - 1;
    int sel0 = ((JTextComponent) getContainer()).getSelectionStart();
    int sel1 = ((JTextComponent) getContainer()).getSelectionEnd();

    try {
        // If the element is empty or there is no selection
        // in this view, just draw the whole thing in one go.
        if (p0 == p1 || sel0 == sel1 || inView(p0, p1, sel0, sel1) == false) {
            drawUnselectedText(g, x, y, 0, contentBuff.count);
            return;
        }

        // There is a selection in this view. Draw up to three regions:
        //   (a) The unselected region before the selection.
        //   (b) The selected region.
        //   (c) The unselected region after the selection.
        // First, map the selected region offsets to be relative
        // to the start of the region and then map them to view
        // offsets so that they take into account characters not
        // present in the model.
        int mappedSel0 = mapOffset(Math.max(sel0 - p0, 0));
        int mappedSel1 = mapOffset(Math.min(sel1 - p0, p1 - p0));

        if (mappedSel0 > 0) {
            // Draw an initial unselected region
            x = drawUnselectedText(g, x, y, 0, mappedSel0);
        }
        x = drawSelectedText(g, x, y, mappedSel0, mappedSel1);

        if (mappedSel1 < contentBuff.count) {
            drawUnselectedText(g, x, y, mappedSel1, contentBuff.count);
        }
    } catch (BadLocationException e) {
        // Should not happen!
