编辑:这是基于 Max 建议的代码

    editor.getControl().addKeyListener(new KeyAdapter() {
        @Override
        public void keyReleased(KeyEvent e) {
            Table table = viewer.getTable();
            int currentIndex = table.getSelectionIndex();

            if (e.keyCode == SWT.ARROW_DOWN) {
                if (currentIndex != table.getItemCount() - 1) {
                    table.setSelection(currentIndex+1);

                    IStructuredSelection sel = (IStructuredSelection) viewer.getSelection();
                    Object rowObj = sel.getFirstElement();

                    viewer.editElement(rowObj, columnIndex);
                }
            }
        }
    });

我有一个带有可编辑列的 JFace TableViewer(通过实现来完成EditingSupport)。

我希望用户在编辑单元格时能够按向上/向下箭头移动到其上方/下方的行。这是我所拥有的:

final TextCellEditor editor = new TextCellEditor(viewer.getTable());

editor.getControl().addKeyListener(new KeyAdapter() {
    @Override
    public void keyReleased(KeyEvent e) {
        if (e.keyCode == SWT.ARROW_DOWN) {
            Table table = viewer.getTable();
            int currentIndex = table.getSelectionIndex();

            if (currentIndex != table.getItemCount() - 1) {
                table.setSelection(currentIndex+1);
            }
        }
    }
});

这会将选定的行移动到下一行,但不会移动文本框,即按下向下箭头后,它看起来像这样:

如何将文本框设置为特定行中的单元格?

使用方法:

org.eclipse.jface.viewers.ColumnViewer.editElement(Object element, int column)
