概要

Htmlで文字列を修飾するとクリップされなくなるので、予めクリップした文字列を作成してからHtmlを使用します。

サンプルコード

class URLRenderer extends DefaultTableCellRenderer
                  implements MouseListener, MouseMotionListener {
  private static Rectangle lrect = new Rectangle();
  private static Rectangle irect = new Rectangle();
  private static Rectangle trect = new Rectangle();
  private int row = -1;
  private int col = -1;
  @Override public Component getTableCellRendererComponent(JTable table, Object value,
                           boolean isSelected, boolean hasFocus,
                           int row, int column) {
    super.getTableCellRendererComponent(table, value, isSelected, false, row, column);

    int mw = table.getColumnModel().getColumnMargin();
    int rh = table.getRowMargin();
    int w  = table.getColumnModel().getColumn(column).getWidth();
    int h  = table.getRowHeight(row);

    Insets i = this.getInsets();
    lrect.x = i.left;
    lrect.y = i.top;
    lrect.width  = w - (mw + i.right  + lrect.x);
    lrect.height = h - (rh + i.bottom + lrect.y);
    irect.x = irect.y = irect.width = irect.height = 0;
    trect.x = trect.y = trect.width = trect.height = 0;

    String str = SwingUtilities.layoutCompoundLabel(
      this,
      this.getFontMetrics(this.getFont()),
      value.toString(), //this.getText(),
      this.getIcon(),
      this.getVerticalAlignment(),
      this.getHorizontalAlignment(),
      this.getVerticalTextPosition(),
      this.getHorizontalTextPosition(),
      lrect,
      irect, //icon
      trect, //text
      this.getIconTextGap());

    if (!table.isEditing() && this.row == row && this.col == column) {
      setText("<html><u><font color='blue'>" + str);
    } else if (hasFocus) {
      setText("<html><font color='blue'>" + str);
    } else {
      setText(str);
      //setText(value.toString());
    }
    return this;
  }
  //...
view all

解説

    • setText("<html><font color='blue'>"+str);で文字列に下線を引く
    • SwingUtilities.layoutCompoundLabel(...)メソッドを使用して文字列をセル幅分のみに省略
    • setText("<html><font color='blue'>"+str);で文字列に下線を引く
