JXTreeTable例子

一个构造树表格的例子，代码如下：

public JXTreeTable getCtgTreeTable() {

  if (ctgTreeTable == null) {

    String dbid = DataClient.RTDBOpen(currentContext, currentApp, null);

          

    /**

     * 表头

     */

    Vector<String> headVector = new Vector<String>();

    headVector.add("开断/越限元件描述");

    headVector.add("开断/越限类型");

    headVector.add("越限个数");

    headVector.add("越限百分比");

    headVector.add("限值");

    headVector.add("计算值");

    headVector.add("厂站ID");

          

    CustomNode root = new CustomNode();// 根节点

    DefaultTreeTableModel treeTableModel = new DefaultTreeTableModel(root, headVector);// 树表格模型        

 

    /**

     * 安全分析开断信息属性字段

     */

    Vector<String> ctgProperty = new Vector<String>();

    ctgProperty.add("id");

    ctgProperty.add("iddescr");

    ctgProperty.add("kdtype");

    ctgProperty.add("vionum");

 

    /**

     * 安全分析越限信息属性字段

     */

    Vector<String> canProperty = new Vector<String>();

    canProperty.add("ictgresult_id");

    canProperty.add("yxdescr");

    canProperty.add("yxtype");

    canProperty.add("yxperlim");

    canProperty.add("calimit");

    canProperty.add("value");

    canProperty.add("istid");

          

    try {

      Vector<Vector<DataUnit>> canVector = DataClient.RTDBRead(dbid, "canlist", canProperty);

             

      NumberFormat format = NumberFormat.getInstance();

      format.setGroupingUsed(false);

      format.setMaximumFractionDigits(2);// 设置小数部分的最大位数为2

             

      /**

       * 安全分析越限信息映射

       */

      Map<Long, Vector<Vector<DataUnit>>> canMap = new HashMap<Long,Vector<Vector<DataUnit>>>();

      for (int i = 0; i < canVector.size(); i++) {

        Vector<DataUnit> data = canVector.get(i);

        if (canMap.containsKey(data.get(0).getLongData())) {

          canMap.get(data.get(0).getLongData()).add(data);

        } else {

          Vector<Vector<DataUnit>> vector = new Vector<Vector<DataUnit>>();

          vector.add(data);

          canMap.put(data.get(0).getLongData(), vector);

        }

      }

             

      /**

       * 构建树表格模型

       */

      Vector<Vector<DataUnit>> ctgVector = DataClient.RTDBRead(dbid, "ctgresult", ctgProperty);

      for (int i = 0; i < ctgVector.size(); i++) {

        Vector<DataUnit> data = ctgVector.get(i);

                 

        if ("故障组".equals(data.get(2).getStringData())) {

          /**

           * 安全分析开断信息列的值

           */

          Vector<String> ctgColumn = new Vector<String>();

          ctgColumn.add(data.get(1).getStringData());

          ctgColumn.add(data.get(2).getStringData());

          ctgColumn.add("" + data.get(3).getLongData());

          ctgColumn.add("");

          ctgColumn.add("");

          ctgColumn.add("");

          ctgColumn.add("");

          CustomNode ctgNode = new CustomNode(ctgColumn);

          treeTableModel.insertNodeInto(ctgNode, root, i);

                    

          Vector<Vector<DataUnit>> vector = canMap.get(data.get(0).getLongData());

          if (vector != null) {

            for (int j = 0; j < vector.size(); j++) {

              Vector<DataUnit> canData = vector.get(j);

                           

              /**

               * 安全分析越限信息列的值

               */

              Vector<String> canColumn = new Vector<String>();

              canColumn.add(canData.get(1).getStringData());

              canColumn.add(canData.get(2).getStringData());

              canColumn.add("");

              canColumn.add(format.format(canData.get(3).getDoubleData()));

              canColumn.add(format.format(canData.get(4).getDoubleData()));

              canColumn.add(format.format(canData.get(5).getDoubleData()));

              canColumn.add("" + canData.get(6).getLongData());

              CustomNode canNode = new CustomNode(canColumn);

              treeTableModel.insertNodeInto(canNode, ctgNode, j);

            }

          }

        }

      }

    } catch (MidLayerAccessException e) {

      e.printStackTrace();

    }

          

    ctgTreeTable = new JXTreeTable(treeTableModel);

    ctgTreeTable.setRootVisible(false);

    ctgTreeTable.setShowsRootHandles(true);

           

    /**

     * 隐藏“厂站ID”列

     */

    ctgTreeTable.getColumnModel().getColumn(6).setMaxWidth(0);

    ctgTreeTable.getColumnModel().getColumn(6).setMinWidth(0);

    /**

     * 设置树表格的渲染器

     */

    ctgTreeTable.setTreeCellRenderer(new TreeNodeIconRenderer());

  }

  return ctgTreeTable;

}

 

 

 

其中类CustomNode代码如下：

public class CustomNode extends DefaultMutableTreeTableNode {

    private Vector<String> rowData = null;// 行数据

 

    public CustomNode() {

       super();

    }

 

    public CustomNode(Vector<String> rowData) {

       super(rowData);

       this.rowData = rowData;

    }

 

    /**

     * 得到列的个数

     */

    public int getColumnCount() {

       return (rowData == null) ? 0 : rowData.size();

    }

 

    /**

     * 得到某列的值

     */

    public Object getValueAt(int column) {

       if (column < 0 || column >= getColumnCount()) {

           throw new IllegalArgumentException("参数column超出索引");

       }

       if (rowData == null)

           return null;

       return rowData.get(column);

    }

 

    public Vector<String> getRowData() {

       return rowData;

    }

 

    public void setRowData(Vector<String> rowData) {

       this.rowData = rowData;

    }

}
