public class MetaColumnModel extends javax.swing.table.DefaultTableColumnModel
This ColumnModel provides enhanced functionality over a normal ColumnModel, aimed at making it easy to select which columns in a related TableModel are shown (appear in this ColumnModel) or not shown (don't appear in this ColumnModel). It does this by using an associated ListModel and ListSelectionModel.- See Also:

MetaColumnModel
public MetaColumnModel(javax.swing.table.TableColumnModel baseColumnModel, javax.swing.table.TableModel tableModel)
Constructs a new MetaColumnModel from a base ColumnModel and a TableModel. The base ColumnModel is taken as the initial list of columns that can appear in this ColumnModel, but they can be deleted from and reinstated to this model without affecting the base. Subsequent changes to the base don't change this either.- Parameters:
baseColumnModel
- the base ColumnModeltableModel
- the TableModel which supplies the data for the columns this object describes; must refer to the same data as baseColumnModel

Method Detail
-
getListModel
public javax.swing.ListModel getListModel()
Returns the ListModel representing all the columns in the original TableColumnModel. Every entry in this ListModel will be aTableColumn
.- Returns:
- the list model
-
getVisibleModel
public javax.swing.ListSelectionModel getVisibleModel()
Returns the ListSelectionModel representing which columns in the original TableColumnModel are currently visible (are represented in this ColumnModel) and which are invisible (are not represented in this ColumnModel).- Returns:
- the selection model
-
addColumn
public void addColumn(javax.swing.table.TableColumn tcol)
When a column is added to this TableColumnModel, add it to the listModel and set it visible in the visibleModel- Specified by:
addColumn
in interfacejavax.swing.table.TableColumnModel
- Overrides:
addColumn
in classjavax.swing.table.DefaultTableColumnModel
-
removeColumn
public void removeColumn(javax.swing.table.TableColumn tcol)
When a column is removed from this TableColumnModel, set it invisible in the visibleModel.- Specified by:
removeColumn
in interfacejavax.swing.table.TableColumnModel
- Overrides:
removeColumn
in classjavax.swing.table.DefaultTableColumnModel
-
removeColumn
public void removeColumn(int ipos)
Sets a column invisible. The column is identified by its position in the list model, equal to its position in the visible model, equal to its position in the base column model from which this model was initialised.- Parameters:
ipos
- position of the column to remove
-
purgeEmptyColumns
public void purgeEmptyColumns()
Purges this column model of any column which contains nothing but blank entries. Columns purged in this way can be reinstated later by modifying the visibleModel. Such a column will also become visible automatically if at a later date it acquires a non-blank entry.
-
makeCheckBoxMenu
public javax.swing.JMenu makeCheckBoxMenu(java.lang.String name)
Returns a menu component which can be used to control the visibility of columns in the model.- Parameters:
