Constructor Detail

DefaultGridModel

public DefaultGridModel()

Constructs a default DefaultGridModel which is a table of zero columns and zero rows.

DefaultGridModel

public DefaultGridModel(int rowCount,
                        int columnCount)

Constructs a DefaultGridModel with rowCount and columnCount of null object values.

Parameters:

rowCount - the number of rows the table holds

columnCount - the number of columns the table holds

See Also:

setValueAt(java.lang.Object, int, int)

DefaultGridModel

public DefaultGridModel(Vector columnNames,
                        int rowCount)

Constructs a DefaultGridModel with as many columns as there are elements in columnNames and rowCount of null object values. Each column's name will be taken from the columnNames vector.

Parameters:

columnNames - vector containing the names of the new columns; if this is null then the model has no columns

rowCount - the number of rows the table holds

DefaultGridModel

public DefaultGridModel(Object[] columnNames,
                        int rowCount)

Constructs a DefaultGridModel with as many columns as there are elements in columnNames and rowCount of null object values. Each column's name will be taken from the columnNames array.

Parameters:

columnNames - array containing the names of the new columns; if this is null then the model has no columns

rowCount - the number of rows the table holds

DefaultGridModel

public DefaultGridModel(Vector data,
                        Vector columnNames)

Constructs a DefaultGridModel and initializes the table by passing data and columnNames to the setDataVector method.

Parameters:

data - the data of the table

columnNames - vector containing the names of the new columns

DefaultGridModel

public DefaultGridModel(Object[][] data,
                        Object[] columnNames)

Constructs a DefaultGridModel and initializes the table by passing data and columnNames to the setDataVector method. The first index in the Object[][] array is the row index and the second is the column index.

Parameters:

data - the data of the table

columnNames - the names of the columns

Method Detail

getColumnName

public String getColumnName(int column)

Overriden to always return null. This forces all column names to come from the column model which can be set by the user.

Specified by:

getColumnName in interface TableModel

Overrides:

getColumnName in class DefaultTableModel

isCellEditable

public boolean isCellEditable(int row,
                              int column)

Returns whether the cell can be edited by the user at run-time.

Specified by:

isCellEditable in interface TableModel

Overrides:

isCellEditable in class DefaultTableModel

Parameters:

row - the row whose value is to be queried

column - the column whose value is to be queried

Returns:

true

See Also:

setValueAt(java.lang.Object, int, int)

getValueAt

public Object getValueAt(int row,
                         int column)

Returns an attribute value for the cell at row and column.

Specified by:

getValueAt in interface TableModel

Overrides:

getValueAt in class DefaultTableModel

setValueAt

public void setValueAt(Object value,
                       int row,
                       int col)

Sets the object value for the cell at column and row. This method will generate a tableChanged notification.

Specified by:

setValueAt in interface TableModel

Overrides:

setValueAt in class DefaultTableModel

sort

public void sort(int column,
                 int sortOrder)

Sorts the model by comparing values in the given column

Specified by:

sort in interface GridModel

Parameters:

column - column to be sorted

sortOrder - One of: DsGrid.ASCENDING, DsGrid.DESCENDING, DsGrid.ASCENDING_CASE, DsGrid.DESCENDING_CASE
