javax.swing.table
interface TableModel

All Known Implementing Classes:
AbstractTableModel, DefaultTableModel

Most common way to construct:

JTable table = …;

TableModel model = table.getModel();

Based on 6 examples


public interface TableModel

The TableModel interface specifies 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);
  

For further documentation, see Creating a Table Model in The Java Tutorial.

 boolean
isCellEditable(int rowIndex, int columnIndex)

          Returns true if the cell at rowIndex and columnIndex is editable.
 void

          Removes a listener from the list that is notified each time a change to the data model occurs.

setValueAt(Object aValue, int rowIndex, int columnIndex)

          Sets the value in the cell at columnIndex and rowIndex to aValue.
 

Method Detail

addTableModelListener

public void addTableModelListener(TableModelListener l)
Adds a listener to the list that is notified each time a change to the data model occurs.

Parameters:
l - the TableModelListener

getColumnClass

public Class getColumnClass(int columnIndex)
Returns the most specific superclass for all the cell values in the column. This is used by the JTable to set up a default renderer and editor for the column.

Parameters:
columnIndex - the index of the column
Returns:
the common ancestor class of the object values in the model.

getColumnCount

public int getColumnCount()
Returns the number of columns in the model. A JTable uses this method to determine how many columns it should create and display by default.

Returns:
the number of columns in the model

getColumnName

public 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 in a table can have the same name.

Parameters:
columnIndex - the index of the column
Returns:
the name of the column

getRowCount

public int getRowCount()
Returns the number of rows in the model. A JTable uses this method to determine how many rows it should display. This method should be quick, as it is called frequently during rendering.

Returns:
the number of rows in the model

getValueAt

public Object getValueAt(int rowIndex,
                         int columnIndex)
Returns the value for the cell at columnIndex and rowIndex.

Parameters:
rowIndex - the row whose value is to be queried
columnIndex - the column whose value is to be queried
Returns:
the value Object at the specified cell

isCellEditable

public 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 to be queried
columnIndex - the column whose value to be queried
Returns:
true if the cell is editable

removeTableModelListener

public void removeTableModelListener(TableModelListener l)
Removes a listener from the list that is notified each time a change to the data model occurs.

Parameters:
l - the TableModelListener

setValueAt

public void setValueAt(Object aValue,
                       int rowIndex,
                       int columnIndex)
Sets the value in the cell at columnIndex and rowIndex to aValue.

Parameters:
aValue - the new value
rowIndex - the row whose value is to be changed
columnIndex - the column whose value is to be changed
