I'm trying to use the example taken from the http://java.sun.com/products/jfc/tsc/articles/treetable2/index.html, in which I've substituted the filesystem model with my model.
I initially create a model, I display it in the JTreeTable
, but now I'd like to update my model and then the JTreeTable
(for example I want to add a node at the tree, modify a node, remove a node, etc.).
どうすればいいのかわかりません。treeNodesChanged
、 などのメソッドしか表示されませんが、このコンポーネントtreeNodesInserted
のグローバル ロジックに何かが欠けている可能性があります。JTreeTable
model.insertNodeInto
また、モデル オブジェクトを持っていないにもかかわらず、さまざまな例で、人々が「モデル」オブジェクト ( 、 )に対してさまざまなメソッドを呼び出すのを見てきたため、モデルを正しく作成したかどうかはmodel.reload
わかりません..上記の例では、単にAbstractTreeTableModel
実装する抽象クラスと呼ばれTreeTableModel
ます..
アップデート
public class TableModel extends AbstractTreeTableModel
implements TreeTableModel {
static protected String[] cNames = {"TrackNumber", "MWRTN", "LSRTN", "RFTN","TrackStatus","Prova","Prova2"};
// Types of the columns.
static protected Class[] cTypes = {TreeTableModel.class,Integer.class, Integer.class, Integer.class, Integer.class,String.class,String.class};
private ArrayList<Object> data=new ArrayList<Object>();
public void insertNode(Object node)
{ this.data.add(node); super.setRoot(data.get(0));}
メイン クラスでは、次の方法でモデルにオブジェクトを追加します。
...
model =new TableModel();
model.insertNode(threatList.get(i)); //inserting the root node
model.addChild(threatList.get(i),threatList.get(j)); // inserting the child
...
次に、モデルを my に渡し、JTreeTable
それをフレームに追加します。
treeTable = new JTreeTable(model);
JScrollPane scroll=new JScrollPane(treeTable);
scroll.setAutoscrolls(false);
scroll.setPreferredSize(new Dimension(1000,80));
frame.add(scroll);
そして、これは JTreeTable クラスです:
public class JTreeTable extends JTable {
protected TreeTableCellRenderer tree;
public JTreeTable(TreeTableModel treeTableModel) {
super();
// Create the tree. It will be used as a renderer and editor.
tree = new TreeTableCellRenderer(treeTableModel);
// Install a tableModel representing the visible rows in the tree.
super.setModel(new TreeTableModelAdapter(treeTableModel, tree));
// Force the JTable and JTree to share their row selection models.
tree.setSelectionModel(new DefaultTreeSelectionModel() {
// Extend the implementation of the constructor, as if:
/* public this() */ {
setSelectionModel(listSelectionModel);
}
});
// Make the tree and table row heights the same.
tree.setRowHeight(getRowHeight());
// Install the tree editor renderer and editor.
setDefaultRenderer(TreeTableModel.class, tree);
setDefaultEditor(TreeTableModel.class, new TreeTableCellEditor());
setShowGrid(false);
setIntercellSpacing(new Dimension(0, 0));
setPreferredSize(new Dimension(60,60));
}
/* Workaround for BasicTableUI anomaly. Make sure the UI never tries to
* paint the editor. The UI currently uses different techniques to
* paint the renderers and editors and overriding setBounds() below
* is not the right thing to do for an editor. Returning -1 for the
* editing row in this case, ensures the editor is never painted.
*/
public int getEditingRow() {
return (getColumnClass(editingColumn) == TreeTableModel.class) ? -1 : editingRow;
}
//
// The renderer used to display the tree nodes, a JTree.
//
public class TreeTableCellRenderer extends JTree implements TableCellRenderer {
protected int visibleRow;
public TreeTableCellRenderer(TreeModel model) {
super(model);
}
public void setBounds(int x, int y, int w, int h) {
super.setBounds(x, 0, w, JTreeTable.this.getHeight());
}
public void paint(Graphics g) {
g.translate(0, -visibleRow * getRowHeight());
super.paint(g);
}
public Component getTableCellRendererComponent(JTable table,
Object value,
boolean isSelected,
boolean hasFocus,
int row, int column) {
if(isSelected)
setBackground(table.getSelectionBackground());
else
setBackground(table.getBackground());
visibleRow = row;
return this;
}
}
//
// The editor used to interact with tree nodes, a JTree.
//
public class TreeTableCellEditor extends AbstractCellEditor implements TableCellEditor {
public Component getTableCellEditorComponent(JTable table, Object value,
boolean isSelected, int r, int c) {
return tree;
}
@Override
public Object getCellEditorValue() {
// TODO Auto-generated method stub
return null;
}
}
私がしたいことは、子を追加 (または変更、または削除) した後にイベントを発生させることです。
