我的應用程序的JFrame的邏輯後的樣子:的JTable內的ScrollPane中只顯示了調整
public Table() {
super("Chess");
thisFrame = this;
tableMenuBar = new JMenuBar();
populateMenuBar();
setJMenuBar(tableMenuBar);
getContentPane().setLayout(new BorderLayout());
chessBoard = new Board(new StandardBoardConfigurator());
gamePanel = new GameHistoryPanel();
chatPanel = new ChatPanel();
takenPiecesPanel = new TakenPiecesPanel();
boardPanel = new BoardPanel(chessBoard);
gameProgress = 1;
highlightLegalMoves = true;
moveLog = new ArrayList<Move>();
gameOver = false;
getContentPane().add(takenPiecesPanel, BorderLayout.WEST);
getContentPane().add(boardPanel, BorderLayout.CENTER);
getContentPane().add(gamePanel, BorderLayout.EAST);
getContentPane().add(chatPanel, BorderLayout.SOUTH);
// Make sure we have nice window decorations.
setDefaultLookAndFeelDecorated(true);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setSize(OUTER_FRAME_DIMENSION);
pack();
setVisible(true);
}
和含有JTable的是「GameHistoryPanel」,裏面有這個,因爲它的構造邏輯JPanel
:
public GameHistoryPanel() {
this.setLayout(new BorderLayout());
this.model = new DataModel();
this.table = new JTable(model);
this.table.setRowHeight(15);
final JScrollPane scrollPane = new JScrollPane(this.table);
scrollPane.setColumnHeaderView(table.getTableHeader());
scrollPane.setPreferredSize(HISTORY_PANEL_DIMENSION);
this.add(scrollPane, BorderLayout.CENTER);
this.currentRow = 0;
this.currentColumn = 0;
this.setVisible(true);
}
的GamePanel
具有這就要求setValueAt
以下更新程序,只要一動即發:
public void increment(final Board board,
final Move move) {
this.model.setValueAt(move, currentRow, currentColumn);
if(board.currentPlayer().getAlliance() == Alliance.WHITE) {
currentColumn++;
} else if (board.currentPlayer().getAlliance() == Alliance.BLACK) {
currentRow++;
currentColumn = 0;
}
}
啓動遊戲後,GamePanel
灰顯。當我調整它垂直時,它突然出現與所有正確的值。我不明白爲什麼。我注意到調整大小會導致getValueAt
被調用很多次。有人能幫助我理解這一點嗎?
編輯2:如果我加入這一行:
this.model.fireTableDataChanged();
遞增,似乎很好地工作。我完全糊塗了......
編輯:這裏是我的TableModel類:
private static class DataModel extends AbstractTableModel {
private static final String[] names = {"White", "Black"};
private final List<Row> values;
public DataModel() {
values = new ArrayList<Row>();
}
@Override
public int getRowCount() {
return values.size();
}
@Override
public int getColumnCount() {
return names.length;
}
@Override
public Object getValueAt(int row, int col) {
final Row currentRow = values.get(row);
if(col == 0) {
return currentRow.getWhiteMove();
} else if (col == 1) {
return currentRow.getBlackMove();
}
return null;
}
@Override
public void setValueAt(Object aValue, int row, int col) {
final Row currentRow;
if(values.size() <= row) {
currentRow = new Row();
values.add(currentRow);
} else {
currentRow = values.get(row);
}
if(col == 0) {
currentRow.setWhiteMove((Move) aValue);
} else if(col == 1) {
currentRow.setBlackMove((Move)aValue);
}
this.fireTableCellUpdated(row, col);
}
@Override
public Class<?> getColumnClass(int col) {
return Move.class;
}
@Override
public String getColumnName(int col) {
return names[col];
}
}
}
您調整哪個組件以使JTable出現? –

如果有幫助,我很樂意將您指向我的gitrepo? –
