我一直在浏览许多有关此的网站并尝试了一些不同的东西,但我很难过。将不胜感激一些帮助。该条件正在检查是否选中了一个复选框(true),但是一旦我执行 model.removeRow(row) 它就会给我这个错误。
public class ExpenditurePanel extends JPanel implements TableModelListener{
private static final long serialVersionUID = 1L;
private static TableModel1 model;
private JTable table;
public ExpenditurePanel() {
model = new TableModel1();
table = new JTable(model);
table.setBorder(new BevelBorder(BevelBorder.LOWERED, null, null, null, null));
table.setRowSelectionAllowed(false);
table.setFillsViewportHeight(true);
table.setCellSelectionEnabled(true);
table.setColumnSelectionAllowed(false);
model.addColumn("Name");
model.addColumn("Week");
model.addColumn("Fortnight");
model.addColumn("Month");
model.addColumn("Year");
model.addColumn("Remove");
Object[] default1 = {"Accomodation","","","","",false};
Object[] default2 = {"Food","","","","",false};
model.addRow(default1);
model.addRow(default2);
model.addTableModelListener(this);
this.add(new JScrollPane(table));
table.setRowSorter(null);
}
public static TableModel1 getModel(){
return model;
}
@Override
public void tableChanged(TableModelEvent e) {
int row = e.getFirstRow();
int column = e.getColumn();
model = (TableModel1) e.getSource();
String columnName = model.getColumnName(column);
Object data = model.getValueAt(row, column);
if(model.getValueAt(row,column) == Boolean.TRUE){
System.out.println("Condition working");
//this part keeps giving me error.
model.removeRow(row);
}
}
}
这就是它抛出的内容:
