[英]Removing combobox as the cell editor of a jtable cell
I have made a combobox as cell editor of a column. 我做了一个组合框,作为一列的单元格编辑器。 I want when i create a new row the cell in that column should not have the combobox as the cell editor and should retain JTextField as the cell editor.
我想要当我创建新行时,该列中的单元格不应具有组合框作为单元格编辑器,而应保留JTextField作为单元格编辑器。 Here is what i have done so far.
这是我到目前为止所做的。
addRow(mainWindow.salesTable);
final TableColumn items = mainWindow.salesTable.getColumnModel().getColumn(0);
final JTextField tfield = new JTextField();
DefaultCellEditor editorqty = new DefaultCellEditor(tfield);
items.setCellEditor(editorqty);
private static void addRow(JTable table) {
DefaultTableModel model = (DefaultTableModel) table.getModel();
Vector row = new Vector();
row.add("");
row.add("");
row.add("");
row.add("");
row.add("");
row.add("");
row.add("");
row.add("");
model.addRow(row);
}
Overriding the getCellEditor(...)
method of JTble is one approach: 重写
getCellEditor(...)
方法是一种方法:
