Interface com.sun.java.swing.table.TableModel
- public interface TableModel
The TableModel interface ispecifies the methods the JTable
will use to interrogate a tabular data model.
The JTable can be set up to display any data model which implements the
TableModel interface with a couple of lines of code:
TableModel myData = new MyTableModel();
JTable table = new JTable(myData);
- See Also:
- JTable, AbstractTableModel
-
addTableModelListener(TableModelListener)
- Add a listener to the list that's notified each time a change
to the data model occurs.
-
getColumnClass(int)
- Returns the lowest common denominator Class in the column.
-
getColumnCount()
- Returns the number of columns managed by the data source object.
-
getColumnName(int)
- Returns the name of the column at columnIndex.
-
getRowCount()
- Returns the number of records managed by the data source object.
-
getValueAt(int, int)
- Returns an attribute value for the cell at columnIndex
and rowIndex.
-
isCellEditable(int, int)
- Returns true if the cell at rowIndex and columnIndex
is editable.
-
removeTableModelListener(TableModelListener)
- Remove a listener from the list that's notified each time a
change to the data model occurs.
-
setValueAt(Object, int, int)
- Sets an attribute value for the record in the cell at
columnIndex and rowIndex.
getRowCount
public abstract int getRowCount()
- Returns the number of records managed by the data source object. A
JTable uses this method to determine how many rows it
should create and display. This method should be quick, as it
is call by JTable quite frequently.
- Returns:
- the number or rows in the model
- See Also:
- getColumnCount
getColumnCount
public abstract int getColumnCount()
- Returns the number of columns managed by the data source object. A
JTable uses this method to determine how many columns it
should create and display on initialization.
- Returns:
- the number or columns in the model
- See Also:
- getRowCount
getColumnName
public abstract String getColumnName(int columnIndex)
- Returns the name of the column at columnIndex. This is used
to initialize the table's column header name. Note, this name does
not need to be unique. Two columns on a table can have the same name.
- Parameters:
- columnIndex - the index of column
- Returns:
- the name of the column
getColumnClass
public abstract Class getColumnClass(int columnIndex)
- Returns the lowest common denominator Class in the column. This is used
by the table to set up a default renderer and editor for the column.
- Returns:
- the common ancestor class of the object values in the model.
isCellEditable
public abstract boolean isCellEditable(int rowIndex,
int columnIndex)
- Returns true if the cell at rowIndex and columnIndex
is editable. Otherwise, setValueAt() on the cell will not change
the value of that cell.
- Parameters:
- rowIndex - the row whose value is to be looked up
- columnIndex - the column whose value is to be looked up
- Returns:
- true if the cell is editable.
- See Also:
- setValueAt
getValueAt
public abstract Object getValueAt(int rowIndex,
int columnIndex)
- Returns an attribute value for the cell at columnIndex
and rowIndex.
- Parameters:
- rowIndex - the row whose value is to be looked up
- columnIndex - the column whose value is to be looked up
- Returns:
- the value Object at the specified cell
setValueAt
public abstract void setValueAt(Object aValue,
int rowIndex,
int columnIndex)
- Sets an attribute value for the record in the cell at
columnIndex and rowIndex. aValue is
the new value.
- Parameters:
- aValue - the new value
- rowIndex - the row whose value is to be changed
- columnIndex - the column whose value is to be changed
- See Also:
- getValueAt, isCellEditable
addTableModelListener
public abstract void addTableModelListener(TableModelListener l)
- Add a listener to the list that's notified each time a change
to the data model occurs.
- Parameters:
- l - the TableModelListener
removeTableModelListener
public abstract void removeTableModelListener(TableModelListener l)
- Remove a listener from the list that's notified each time a
change to the data model occurs.
- Parameters:
- l - the TableModelListener
