Java Swing 表问题

Question

大家好，正在制作 Activity 日历。我在显示列标题时遇到一些问题..这是代码

private JTable calendarTable;
private DefaultTableModel calendarTableModel; 

final private String [] days = {"Sunday", "Monday", "Tuesday",
                                    "Wednesday", "Thursday", "Friday",
                                    "Saturday"};
//////////////////////////////////////////////////////////////////////
/* Setup the actual calendar table */


calendarTableModel = new DefaultTableModel() {
    public boolean isCellEditable(int row, int col){
             return false;
    }
};

// setup columns
for(int i = 0; i < 7; i++)
    calendarTableModel.addColumn(days[i]); 

calendarTable = new JTable(calendarTableModel);

calendarTable.getTableHeader().setResizingAllowed(false);
calendarTable.getTableHeader().setReorderingAllowed(false);

calendarTable.setColumnSelectionAllowed(true);
calendarTable.setRowSelectionAllowed(true);
calendarTable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

calendarTable.setRowHeight(105);
calendarTableModel.setColumnCount(7);
calendarTableModel.setRowCount(6);

另外，我对表格有点陌生。我怎样才能在表格的最大大小之间分割 rowHeight ？

Answer 1

表格标题

要么将calendarTable放入JScrollPane中，要么添加calendarTable.getTableHeader()。

行高

添加一个监听器，以便在调整表格大小时更改行高。

calendarTable.addComponentListener(new ComponentAdapter() {
    public void componentResized(ComponentEvent evt) {
        if (evt.getID() == ComponentEvent.COMPONENT_RESIZED) {
            calendarTable.setRowHeight(calendarTable.getHeight() / calendarTable.getRowCount());
        }
    }
});
