Re: [platform-swt-dev] TableViewer and cell editors queston

[vijay reddy <vijay_felicity@xxxxxxxxx>]

I forgot to give the code for populateFields method.

Here is the code 

            //populate fields method
     populateFields(Row currentrow,String currentTable){
          //calls another method to get table fields in a string array
            String[] tempFields = loadCurrentTableFields(currentTable);
            currentrow.setComboFields(tempFields);
            String[] temp=currentrow.getComboFields();
            if (tempFields != null) 
                    editors[1] = new ComboBoxCellEditor(table, temp,     SWT.READ_ONLY);

       
 }

I am using table viewer with 2 columns to populate database tables
in first column and corresponding table fields in second column.

I am using combobox cell editors on two columns.In my implementation I wrote listerners to keep
track of changes on selection of first column combo box.For every change in selection of combo item
I need to repopulate the corresponding fields in the second column.

            editors[0] = new ComboBoxCellEditor(table, populateTables(), SWT.READ_ONLY);
                        CCombo DBtableCCombo=(CCombo)tableCCombo.getControl();

            DBtableCCombo.addModifyListener(new ModifyListener() {
                public void modifyText(ModifyEvent e) {
                    String currentTable = DBtableCCombo.getText();
                    System.out.println("Table modified" + currentTable);

                        Row currentrow = (Row) ((IStructuredSelection)
                                tableviewer.getSelection()).getFirstElement();

                        //for currentrow,populate combo box in second column with current table fields
                        populateFields(currentrow,currentTable);

                    });

            //populate fields method
            populateFields(Row currentrow,String currentTable){
        
            }
Eventhough this code is repopulating the DBfields it is not populating the way I need.
Everytime a modifytext event is fired on DBtableCCOmbo the previously populated
DBfields in the second column are again repopulating with the current table's DBfields.

The way I need is that the previously populated DBfields should remain intact.Only currentrow's items are to be changed
when an modify event fires.

I think I can figure out this problem if there is a way where I can apply a comboboxcelleditor for each cell in the second column
instead of comboboxcelleditor for whole second column.

Any help will be appreciated
thanks
Vijay
