JTable与复杂的编辑器 [英] JTable with a complex editor

问题描述

我有很多针对JTable的自定义编辑器，并且很难说可用性，特别是关于使用键盘进行编辑的可用性。

I have many custom editors for a JTable and it's an understatement to say that the usability, particularly in regard to editing with the keyboard, is lacking.

主要原因是我的编辑总是创建一个类似的（虽然通常更复杂）的情况：

The main reason for this is that my editors are always created with a similar (though often more complex) situation to this:

@Override
public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) {
  JPanel container = new JPanel();
  container.setLayout(new BorderLayout());
  container.add(field, BorderLayout.CENTER);
  field.setText((String) value);
  container.add(new JButton("..."), BorderLayout.EAST);
  return container;
}

I.E内部有多个组件的面板。实际的文本编辑器是作为编辑器返回的组件的后代。
因此，抛出问题，从我所知道的，JTable正在关注 getTableCellEditorComponent 方法返回的组件，所以当你按下一个键时单元格突出显示它将焦点和按键传递给面板，认为是编辑器。

无论如何我可以通知JTable真正的编辑器是JTextfield吗？
在正确的组件上添加hacky requestFocusInWindow 是不够的，因为按键不会被传递。

I.E a panel with more than one component inside. The actual text editor is a descendant of the component being returned as the editor. So, rendering issues aside, from what I can tell, the JTable is focusing the component that is returned by the getTableCellEditorComponent method so when you press a key with a cell highlighted it passes focus and the key press to the panel, thinking that's the editor.
Is there anyway I can inform JTable that the "real" editor is the JTextfield? Adding a hacky requestFocusInWindow on the correct component is insufficient as the key press won't get passed on.
