What kind of event is generate when start in cell?

Question

Hi!
I set JTextField as a cell editor.Let's in cell we have some string, e.g: "test". When I double click in cell and start type, e.g. "12", the methods of KeyListener (keyPressed and so on) are calls and the result string is "test12". OK.
But when I only select cell (the caret is not blink in cell) and start type, e.g "12" the result is again "test12", but the methods of KeyListener DO NOT CALLS. Why? And how I can get additional symbols which I type (in this case this is a "12") in cell?
Thank you.

Hi,
sorry, I can't find the classes TableScrollPane and JdbTable in the JDK - but, I guess, JdbTable is perhaps a subclass of JTable. If that is so, it will have a TableColumnModel, which you can get by use of its getColumnModel()-method.
You are now able to add a ColumnModelListener to that model by use of its method addColumnModelListener(...). Here you pass a reference to an instance of a class, that implements the TableColumnModelListener interface. Via this interface you will get the folliowing notifications:
public void columnAdded(TableColumnModelEvent e)
Tells listeners that a column was added to the model.
public void columnMarginChanged(ChangeEvent e)
Tells listeners that a column was moved due to a margin change.
public void columnMoved(TableColumnModelEvent e)
Tells listeners that a column was repositioned.
public void columnRemoved(TableColumnModelEvent e)
Tells listeners that a column was removed from the model.
public void columnSelectionChanged(ListSelectionEvent e)
Tells listeners that the selection model of the TableColumnModel changed.
If your JdbTable is a subclass of JTable you can use that way, because the used reference to the TableColumnModel is a reference to an interface, so this is independent of the class, that is actually used to represent this model - only interface methods are used.
