Editable JComboBox in JTable not working without hitting Enter Key

[Priya Sri]

Hi,

i have a problem using an editable JComboBox as cell editor in a JTable.

When i edit the combo and then I press the TAB or ENTER key then all works fine and the value in the TableModel is updated with the edited one,
but
if i leave the cell with the mouse
or
traverse to another cell through arrow keys
or
click on any other cell, the typed value is going off

and the value is not passed to the TableModel. Why ? Is there a way to solve this problem ?

Regards
Priya Sri

table.putClientProperty("terminateEditOnFocusLost", val);

Next time I suggest you SearchFirst because I have posted this code at least 2 or 3 times before, in answer to similar questions.

I have added this line. But it is not working.
Can you describe in detail.

[Rob Spoor]

Ehm sorry. "val" should be Boolean.TRUE.

Rob,

Tried this. but no change...

If you have an examples of editable Jcombobox in JTable working without hitting enter key... I searched in this site as well.. but not found useful links. please post that if you have any.

Example : Jcombobox has 3 choices. On selecting 3 rd choice, it should become editable and user should key the value. Now at this point, user move the tab or click on the mouse, the entered value should be selected in the jcombo box.

But jcombobox is taking the value only on click of enter key.

Thanks.

i have _exactly_ the same problem. i already wasted hours to find a solution, but no luck.
i would be glad for any help!

while implementing my own CellEditor i found out, that getCellEditorValue() is called before the editable combox has "updated" the string. so getSelectedItem() still returns the old value but shortly after that it would return the right value!
somehow there should be a method like "combobox.stopEditing()" or something...

my example:

   public class ComboBoxCellEditor extends AbstractCellEditor implements TableCellEditor {
      private static final long serialVersionUID = 4170056738609945778L;

      private JComboBox jcb;

      private ArrayList<String> choice;

      public ComboBoxCellEditor(ArrayList<String> choice) {
         this.choice = choice;
      }

      @Override
      public JComponent getTableCellEditorComponent(JTable table, Object item, boolean isSelected, int row, int column) {
         jcb = new JComboBox(choice.toArray());
         jcb.setEditable(true);

         if (item != null) {
            jcb.setSelectedItem(item);
         }

         return jcb;
      }

      @Override
      public Object getCellEditorValue() {
         return jcb.getSelectedItem(); // change to return jcb.getEditor().getItem();
      }
   }

EDIT: I found a solution! This does the trick:

  public Object getCellEditorValue() {
         return jcb.getEditor().getItem();
      }
