Class DefaultTableColumnModelExt

java.lang.Object
javax.swing.table.DefaultTableColumnModel
org.jdesktop.swingx.table.DefaultTableColumnModelExt
All Implemented Interfaces:
PropertyChangeListener, Serializable, EventListener, ListSelectionListener, TableColumnModel, TableColumnModelExt
public class DefaultTableColumnModelExt extends DefaultTableColumnModel implements TableColumnModelExt
A default implementation of TableColumnModelExt.

TODO: explain sub-optimal notification on showing/hiding columns. (hot fixed issues #156, #157. To really do it need enhanced TableColumnModelEvent and -Listeners that are aware of the event.)

    • getColumns

      public List<TableColumn> getColumns(boolean includeHidden)
      Returns a List of contained TableColumns. Includes or excludes invisible columns, depending on whether the includeHidden is true or false, respectively. If false, an Iterator over the List is equivalent to the Enumeration returned by getColumns().

      NOTE: the order of columns in the List depends on whether or not the invisible columns are included, in the former case it's the insertion order in the latter it's the current order of the visible columns.

      Specified by:
      getColumns in interface TableColumnModelExt
      Parameters:
      includeHidden - a boolean to indicate whether invisible columns should be included
      Returns:
      a List of contained columns.

    • getColumnCount

      public int getColumnCount(boolean includeHidden)
      Returns the number of contained columns. The count includes or excludes invisible columns, depending on whether the includeHidden is true or false, respectively. If false, this method returns the same count as getColumnCount().
      Specified by:
      getColumnCount in interface TableColumnModelExt
      Parameters:
      includeHidden - a boolean to indicate whether invisible columns should be included
      Returns:
      the number of contained columns, including or excluding the invisible as specified.

    • getColumnExt

      public TableColumnExt getColumnExt(Object identifier)
      Returns the first TableColumnExt with the given identifier. The return value is null if there is no contained column with identifier or if the column with identifier is not of type TableColumnExt. The returned column may be visible or hidden.
      Specified by:
      getColumnExt in interface TableColumnModelExt
      Parameters:
      identifier - the object used as column identifier
      Returns:
      first TableColumnExt with the given identifier or null if none is found

    • getColumnExt

      public TableColumnExt getColumnExt(int columnIndex)
      Returns the TableColumnExt at view position columnIndex. The return value is null, if the column at position columnIndex is not of type TableColumnExt. The returned column is visible.
      Specified by:
      getColumnExt in interface TableColumnModelExt
      Parameters:
      columnIndex - the index of the column desired
      Returns:
      the TableColumnExt object that matches the column index

    • isRemovedToInvisibleEvent

      public boolean isRemovedToInvisibleEvent(int oldIndex)
      hot fix for #157: listeners that are aware of the possible existence of invisible columns should check if the received columnRemoved originated from moving a column from visible to invisible.
      Parameters:
      oldIndex - the fromIndex of the columnEvent
      Returns:
      true if the column was moved to invisible

    • isAddedFromInvisibleEvent

      public boolean isAddedFromInvisibleEvent(int newIndex)
      hot fix for #157: listeners that are aware of the possible existence of invisible columns should check if the received columnAdded originated from moving a column from invisible to visible.
      Parameters:
      newIndex - the toIndex of the columnEvent
      Returns:
      true if the column was moved to visible

    • removeColumn

      public void removeColumn(TableColumn column)

      Overridden to update internals related to column visibility.

      Specified by:
      removeColumn in interface TableColumnModel
      Overrides:
      removeColumn in class DefaultTableColumnModel

    • addColumn

      public void addColumn(TableColumn aColumn)

      Overridden to update internals related to column visibility.

      Specified by:
      addColumn in interface TableColumnModel
      Overrides:
      addColumn in class DefaultTableColumnModel

    • moveColumn

      public void moveColumn(int columnIndex, int newIndex)

      Overridden to update internals related to column visibility.

      Specified by:
      moveColumn in interface TableColumnModel
      Overrides:
      moveColumn in class DefaultTableColumnModel

    • moveToInvisible

      protected void moveToInvisible(TableColumnExt col)
      Update internal state after the visibility of the column was changed to invisible. The given column is assumed to be contained in this model.
      Parameters:
      col - the column which was hidden.

    • moveToVisible

      protected void moveToVisible(TableColumnExt col)
      Update internal state after the visibility of the column was changed to visible. The given column is assumed to be contained in this model.
      Parameters:
      col - the column which was made visible.

    • getEventListenerList

      protected EventListenerList getEventListenerList()
      Exposed for testing only - don't use! Will be removed again!
      Returns:
      super's listener list

    • propertyChange

      public void propertyChange(PropertyChangeEvent evt)
      Specified by:
      propertyChange in interface PropertyChangeListener
      Overrides:
      propertyChange in class DefaultTableColumnModel

    • fireColumnPropertyChange

      protected void fireColumnPropertyChange(PropertyChangeEvent evt)
      Notifies TableColumnModelExtListeners about property changes of contained columns. The event instance is the original as fired by the TableColumn.
      Parameters:
      evt - the event received

    • addColumnModelListener

      public void addColumnModelListener(TableColumnModelListener x)
      Adds a listener for table column model events. This enhances super's behaviour in that it guarantees to notify listeners of type TableColumnModelListenerExt about property changes of contained columns.

      Overridden to install enhanced notification of listeners of type. TableColumnModelListenerExt about property changes of contained columns.

      Specified by:
      addColumnModelListener in interface TableColumnModel
      Specified by:
      addColumnModelListener in interface TableColumnModelExt
      Overrides:
      addColumnModelListener in class DefaultTableColumnModel
      Parameters:
      x - a TableColumnModelListener object

    • removeColumnModelListener

      public void removeColumnModelListener(TableColumnModelListener x)

      Overridden to uninstall enhanced notification of listeners of type. TableColumnModelListenerExt about property changes of contained columns.

      Specified by:
      removeColumnModelListener in interface TableColumnModel
      Overrides:
      removeColumnModelListener in class DefaultTableColumnModel

    • getTableColumnModelExtListeners

      public TableColumnModelExtListener[] getTableColumnModelExtListeners()
      Returns:
      array of all registered listeners
