Thread: how to know if cell was changed in tableviewer

I created tableviewer ( jface ).

All the columns are editable ( using EditingSupport )

I want to know when cell is changed and then

to raise a flag in other column. meaning that you start to write any data in the cell

I know that I need to create event of key changed listener to the cells. ( or there is different way )

How I can have access to the cell ? where do I need to add the event

public class MyGridViewer extends TableViewer {
public MyGridViewer (Composite parent) {
super(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL | SWT.FULL_SELECTION | SWT.BORDER);

final Table table = this.getTable();
table.setHeaderVisible(true);
table.setLinesVisible(true);

this.setContentProvider(new MyModelProvider());

@Override
protected void inputChanged(Object input, Object oldInput) {

removeColumn();



tableCol = new TableViewerColumn(this, SWT.NONE);
column = tableCol.getColumn();
column.setText(dataColumnHeader.getName());
column.setWidth(100);
column.setResizable(true);
column.setMoveable(true);
tableCol.setLabelProvider(new ColumnLabelProvider() {
@Override
public String getText(Object element) {
DataRow r = (DataRow) element;
DataCell c = r.getDataCellByName(dataColumnHeader.getName());
if (c != null && c.getValue() != null) {
return c.getValue().toString();
}
return null;
}
});


editingSupport = new StringCellEditingSupport(this, dataColumnHeader);
tableCol.setEditingSupport(editingSupport);
super.inputChanged(input, oldInput);
}

I created tableviewer ( jface ).

I want to save the changes in the table.

I Added a button of save.

The issue that I tried change the value in the cell ( the focus is still on the cell ) I press save and I want to read the value that changed.The issue that I always see the old value and not the new value.

If I changed the focus of the cell then it is working.

Do I need to add event for the editing in the cell ?

The button is above the table
