AbstractGWTTableModel

public AbstractGWTTableModel()

Creates a default instance.

Method Detail

getColumnName

public String getColumnName(int columnIndex)

Returns the name of the specified column. This method generates default names in a sequence (starting with column 0): A, B, C, ..., Z, AA, AB, AC, ..., AZ, BA, BB, BC, and so on. Subclasses may override this method to allow column names to be specified on some other basis.

Specified by:

getColumnName in interface GWTTableModel

Parameters:

columnIndex - the column index.

Returns:

The name of the column.

findColumn

public int findColumn(String columnName)

Return the index of the specified column, or -1 if there is no column with the specified name.

Parameters:

columnName - the name of the column (null not permitted).

Returns:

The index of the column, -1 if not found.

Throws:

NullPointerException - if columnName is null.

See Also:

getColumnName(int)

getColumnClass

public Class<?> getColumnClass(int columnIndex)

Returns the Class for all Object instances in the specified column.

Specified by:

getColumnClass in interface GWTTableModel

Parameters:

columnIndex - the column index.

Returns:

The class.

isCellEditable

public boolean isCellEditable(int rowIndex,
                     int columnIndex)

Returns true if the specified cell is editable, and false if it is not. This implementation returns false for all arguments, subclasses should override the method if necessary.

Specified by:

isCellEditable in interface GWTTableModel

Parameters:

rowIndex - the row index of the cell.

columnIndex - the column index of the cell.

Returns:

false.

setValueAt

public void setValueAt(Object value,
              int rowIndex,
              int columnIndex)

Sets the value of the given cell. This implementation ignores all arguments and does nothing, subclasses should override the method if necessary.

Specified by:

setValueAt in interface GWTTableModel

Parameters:

value - the new value (null permitted).

rowIndex - the row index of the cell.

columnIndex - the column index of the cell.

addTableModelListener

public void addTableModelListener(TableModelListener listener)

Adds a listener to the table model. The listener will receive notification of all changes to the table model.

Specified by:

addTableModelListener in interface GWTTableModel

Parameters:

listener - the listener.

removeTableModelListener

public void removeTableModelListener(TableModelListener listener)

Removes a listener from the table model so that it will no longer receive notification of changes to the table model.

Specified by:

removeTableModelListener in interface GWTTableModel

Parameters:

listener - the listener to remove.

getTableModelListeners

public TableModelListener[] getTableModelListeners()

Returns an array containing the listeners that have been added to the table model.

Returns:

Array of TableModelListener objects.

Since:

1.4
