Combo Box in Jide TAble

[Kalyani]

Hi ,

My client wants me to convert one column of the JIDE Table into a combo box. So, instead of an editable cell, he will get a combo box for one column only. Is that possible ?
Kindly help.

Regards,
Kalyani

Let me make sure I got it correctly. Do you mean just ONE combobox for a WHOLE column? No cells at all in that column?

[Kalyani]

No. Am sorry for not having been clear. I want a comboBox for every cell in that column. So instead of seeing a cell where you enter data in that column, you will view a comboBox.

It sounds like you want to use a combobox as the cell editor. If you are using JIDE Grids, the recommended way is to register a cell editor based on JComboBox or ExComboBox using CellEditorManager using a data type and an EditorContext, then implement ContextSensitiveTableModel interface on your table model and return the data type and the EditorContext to match your registration on the CellEditorManager. JIDE Grids provided a bunch of cell editors based on ExComboBox such as for Enums, Date, Calendar, Insets etc.

Hi,
I am trying to show comboBox in one of the table columns..As suggested in above post, i registered a editor context by creating a celleditor like:

Code: Select all

  ObjectConverterManager.initDefaultConverter();
        CellRendererManager.initDefaultRenderer();
        CellEditorManager.initDefaultEditor();

        CellEditorManager.registerEditor(String.class, new CellEditorFactory() {

            public CellEditor create()
            {
                AbstractComboBoxCellEditor editor = new AbstractComboBoxCellEditor() {
                    @Override
                    public AbstractComboBox createAbstractComboBox()
                    {
                        DefaultComboBoxModel comboBoxModel = new DefaultComboBoxModel(
                                new String[]{"One", "Two"});
                        return new ListComboBox(comboBoxModel);
                    }
                };
                return editor;
            }
        }, PN_CONTEXT);


and in table model which implmenet ContextSensitiveTableModel, getEditorcontext is overridden as :

Code: Select all

return column == 1 ? ListStyleOptionsDialog.PN_CONTEXT : super.getEditorContextAt(row, column);


Still, comboBox is not shown in column 1 and also, no other columns are selected when a row is selected exception column 0.
Note: column 0 is a tristatecheckbox

Please try to instantiate a ListComboBoxCellEditor instead of AbstractComboBoxCellEditor.

Thanks for your quick reply..I am able to show combo box in table column.

Can I filter values in combo box based on selected row? like show only subset of values specified in editor context...

Also as soon as I add a row, i want to focus combo box column .Below code doesnt seem to be working... only new row is being selcted.

_sortableTable.getSelectionModel().setSelectionInterval(index, index);
_sortableTable.changeSelection(index,2,false,true);

_sortableTable.requestFocusInWindow();

Please give JIDE PropertyPaneDemo a try. The property "Multiple Values" will change its selectable entries based on the value of the property "priority".

Please try to invoke JTable#setColumnSelectionAllowed(true) to select the cell only.

Thanks,

JTable#setColumnSelectionAllowed(true) selects specific column only.

I want to highlight the column within the selected row..

JTable#ChangeSelection() should be able to "highlight" the cell, which has a dash line surrounding the cell. It looks to me like a editing status from the image you posted. If this is what you want, please try to manipulate a key event or mouse event to invoke JTable#editCellAt().

Thanks,
