java - JScrollPane 不能水平工作

标签 java jscrollpane horizontal-scrolling

enter image description here

嗨。我需要一些帮助。 JScrollPane 在垂直方向上工作良好，但在水平方向上却不行。我找不到问题所在。我知道这是一个有点大的项目，有很多令人困惑的代码，但我不能删除任何那个功能。

public final class Salary extends javax.swing.JFrame {

private SalaryTableModel tableModel;
public int selectedRow = -1;
public static String bolme;
public static String ay;
public static int il = 0;
private final String selectedItem_Bolme;
private final String selectedItem_Ay;
private final int selectedItem_Il;
private List<Pojo> sortedList;
public TableColumn date;
public static int bolmeId = 0;
public static String ad;
public static int row2;

public void visible(String bolme2, String ay2, int il2) {
    il = il2;
    ay = ay2;
    bolme = bolme2;
    new Salary().setVisible(true);
}

public RXTable autoResizeColWidth(RXTable table, SalaryTableModel model) {
    table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
    table.setModel(model);
    int margin = 5;
    for (int i = 0; i < table.getColumnCount(); i++) {
        int vColIndex = i;
        DefaultTableColumnModel colModel = (DefaultTableColumnModel) table.getColumnModel();
        TableColumn col = colModel.getColumn(vColIndex);
        int width;
        TableCellRenderer renderer = col.getHeaderRenderer();
        if (renderer == null) {
            renderer = table.getTableHeader().getDefaultRenderer();
        }
        Component comp = renderer.getTableCellRendererComponent(table, col.getHeaderValue(), false, false, 0, 0);
        width = comp.getPreferredSize().width;
        for (int r = 0; r < table.getRowCount(); r++) {
            renderer = table.getCellRenderer(r, vColIndex);
            comp = renderer.getTableCellRendererComponent(table, table.getValueAt(r, vColIndex), false, false,
                    r, vColIndex);
            width = Math.max(width, comp.getPreferredSize().width);
        }
        width += 2 * margin;
        col.setPreferredWidth(width);
    }
    ((DefaultTableCellRenderer) table.getTableHeader().getDefaultRenderer()).setHorizontalAlignment(
            SwingConstants.LEFT);

最佳答案

如果您想要显示单元格的全文而不是缩写，您可以使用 Table Column Adjuster .例如:

String[] columnNames = {"Colum1", "Colum2", "Colum2"};
String[][] data = {
    {"ABCDEFGHIJKLMNOPQRSTUVWXYZ", "-", "-"},
    {"-", "ABCDEFGHIJKLMNOPQRSTUVWXYZ", "-"},
    {"-", "-", "ABCDEFGHIJKLMNOPQRSTUVWXYZ"}
};
TableModel model = new DefaultTableModel(data, columnNames);

JTable table = new JTable();
table.setModel(model);
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

TableColumnAdjuster tca = new TableColumnAdjuster(table);
tca.adjustColumns();

JScrollPane pane = new JScrollPane(table);
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(pane);
frame.setSize(400, 300);
frame.setVisible(true);

TableColumnAdjuster example
