Interface TableModel

  • All Known Implementing Classes:
    AbstractTableModel, DefaultTableModel


    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.

    • Method Detail

      • getRowCount

        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
        See Also:
        getColumnCount()
      • getColumnCount

        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
        See Also:
        getRowCount()
      • getColumnName

        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
      • getColumnClass

        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.
      • isCellEditable

        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
        See Also:
        setValueAt(java.lang.Object, int, int)
      • getValueAt

        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
      • setValueAt

        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
        See Also:
        getValueAt(int, int), isCellEditable(int, int)
      • addTableModelListener

        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
      • removeTableModelListener

        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
