Class SingleColumn

java.lang.Object
  javax.swing.table.TableColumn
      com.jidesoft.grid.AbstractCalculatedColumn
          com.jidesoft.grid.SingleColumn

All Implemented Interfaces:

CalculatedColumn, Serializable

public class SingleColumn
extends AbstractCalculatedColumn

A direct mapping from a single existing column of a table model. It can be used with CalculatedTableModel to create a completely new table model based on the original table model. The SingleColumn can be created based on the column index or the column name (the first one in case there are duplicated column names) as in the original table model. By default it will gets the same column name and the same column class. However you can define a new column name and a new column class. If the actual model is a ContextSensitiveTableModel, the SingleColumn will automatically find the ConverterContext and EditorContext defined in the ContextSensitiveTableModel and set them.

Method Detail

getColumnIndex

public int getColumnIndex()

Gets the column index as in the actual table model.

Returns:

the column index as in the actual table model.

setColumnIndex

public void setColumnIndex(int columnIndex)

Sets the column index as in the actual table model. This method will update the column name, column class, converter context and editor context.

Parameters:

columnIndex - the column index as in the actual table model.

setObjectGrouper

public void setObjectGrouper(ObjectGrouper objectGrouper)

Overrides:

setObjectGrouper in class AbstractCalculatedColumn

getValueAt

public Object getValueAt(int rowIndex)

Gets the value at the specified row index.

Parameters:

rowIndex - the row index.

Returns:

the value at the specified row index.

setValueAt

public void setValueAt(Object value,
                       int rowIndex)

Sets the value at the specified row index.

Parameters:

value - a new value at the specified row index.

rowIndex - the row index.

isCellEditable

public boolean isCellEditable(int rowIndex)

Checks if the cell is editable at the specified row index. If getObjectGrouper() is not null, this method will return false as there is usually no way to edit a grouped value (because grouping is one direction). Otherwise, it will return the value from the actual model's isCellEditable method.

Parameters:

rowIndex - the row index.

Returns:

true if the cell is editable. Otherwise false.

getDependingColumns

public int[] getDependingColumns()

Gets the depending column index. By default, it will be getColumnIndex().

Returns:

the depending column index.
