java JTable刷新问题
JTable初始化后，从数据库中查询30调数据，先是到表格中，
现在要在数据行数不变的情况下，不断的一条条刷新数据，并更新原有的数据。请问那位高手可以说一下
我是用的是继承自AbstractTableModel，谁能说下思路，或者给个几步过程也行
[解决办法]
没有测试，看看是不是这个意思：
import java.util.LinkedList;import java.util.List;import javax.swing.SwingUtilities;import javax.swing.table.AbstractTableModel;/** * * @date 17/10/2012 */public class SizeFixedStackTableModel<R> extends AbstractTableModel { public static interface RecordRenderer<R> { int getColumnCount(); /** * * @param record * @param column * @return * @throws IndexOutOfBoundsException when column is not valid * {@code ( column < 0 || column >= getColumnCount() )} */ Object getValueAt(R record, int column); } private final RecordRenderer<? super R> recordRenderer; private volatile int size; private List<R> records; public SizeFixedStackTableModel(RecordRenderer<? super R> recordRenderer, int size) { if( recordRenderer == null ) throw new NullPointerException(); if( size < 0 ) throw new IllegalArgumentException(); this.recordRenderer = recordRenderer; this.size = size; this.records = new LinkedList<R>(); } @Override public int getRowCount() { assert SwingUtilities.isEventDispatchThread(); return Math.min(size, records.size()); } @Override public int getColumnCount() { assert SwingUtilities.isEventDispatchThread(); return recordRenderer.getColumnCount(); } @Override public Object getValueAt(int rowIndex, int columnIndex) { assert SwingUtilities.isEventDispatchThread(); // potentially throws IndexOutOfBoundsException R record = records.get(rowIndex); return recordRenderer.getValueAt(record, columnIndex); } public void setSize(int size) { if( size < 0 ) throw new IllegalArgumentException("Invalid table model size: " + size); if( this.size == size ) return; this.size = size; fireTableDataChanged(); } public void insert(final R record) { if( SwingUtilities.isEventDispatchThread() ) { records.add(0, record); fireTableDataChanged(); } else { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { insert(record); } }); } }}
