从JTable返回JComboBox

Question

so I've got a number of JComboBox's which make up a JTable. My question is; without having access to these JComboBox's directly, how can I obtain them from the JTable? Below is how I've put the JComboBoxes into the JTable...

TableColumn columnModel = table.getColumnModel().getColumn(i);
columnModel.setCellEditor(new DefaultCellEditor(combo));

...So I would imagine that you can return them by doing something like...

JComboBox retrievedDropDowns = (JComboBox)table.getColumnModel().getColumn(1).getCellEditor();

But apparently not...

Am I far off?

Thanks!

Answer 1

尝试：

JComboBox retrievedDropDowns = (JComboBox)table.getColumnModel().getColumn(i).getCellEditor().getComponent();

Answer 2

If you put a DefaultCellEditor in your columnModel then it will return a DefaultCellEditor not a JComboBox .

But you can use DefaultCellEditor.getComponent() to get the inner editorComponent.
