Interface TableColumnModel

Method Detail

• addColumn

  void addColumn(TableColumn aColumn)

  Appends aColumn to the end of the tableColumns array. This method posts a columnAdded event to its listeners.

  Parameters:

  aColumn - the TableColumn to be added

  See Also:

  removeColumn(javax.swing.table.TableColumn)

• removeColumn

  void removeColumn(TableColumn column)

  Deletes the TableColumn column from the tableColumns array. This method will do nothing if column is not in the table's column list. This method posts a columnRemoved event to its listeners.

  Parameters:

  column - the TableColumn to be removed

  See Also:

  addColumn(javax.swing.table.TableColumn)

• moveColumn

  void moveColumn(int columnIndex,
                int newIndex)

  Moves the column and its header at columnIndex to newIndex. The old column at columnIndex will now be found at newIndex. The column that used to be at newIndex is shifted left or right to make room. This will not move any columns if columnIndex equals newIndex. This method posts a columnMoved event to its listeners.

  Parameters:

  columnIndex - the index of column to be moved

  newIndex - index of the column's new location

  Throws:

  IllegalArgumentException - if columnIndex or newIndex are not in the valid range

• setColumnMargin

  void setColumnMargin(int newMargin)

  Sets the TableColumn's column margin to newMargin. This method posts a columnMarginChanged event to its listeners.

  Parameters:

  newMargin - the width, in pixels, of the new column margins

  See Also:

  getColumnMargin()

• getColumnCount

  int getColumnCount()

  Returns the number of columns in the model.

  Returns:

  the number of columns in the model

• getColumns

  Enumeration<TableColumn> getColumns()

  Returns an Enumeration of all the columns in the model.

  Returns:

  an Enumeration of all the columns in the model

• getColumnIndex

  int getColumnIndex(Object columnIdentifier)

  Returns the index of the first column in the table whose identifier is equal to identifier, when compared using equals.

  Parameters:

  columnIdentifier - the identifier object

  Returns:

  the index of the first table column whose identifier is equal to identifier

  Throws:

  IllegalArgumentException - if identifier is null, or no TableColumn has this identifier

  See Also:

  getColumn(int)

• getColumn

  TableColumn getColumn(int columnIndex)

  Returns the TableColumn object for the column at columnIndex.

  Parameters:

  columnIndex - the index of the desired column

  Returns:

  the TableColumn object for the column at columnIndex

• getColumnMargin

  int getColumnMargin()

  Returns the width between the cells in each column.

  Returns:

  the margin, in pixels, between the cells

• getColumnIndexAtX

  int getColumnIndexAtX(int xPosition)

  Returns the index of the column that lies on the horizontal point, xPosition; or -1 if it lies outside the any of the column's bounds. In keeping with Swing's separable model architecture, a TableColumnModel does not know how the table columns actually appear on screen. The visual presentation of the columns is the responsibility of the view/controller object using this model (typically JTable). The view/controller need not display the columns sequentially from left to right. For example, columns could be displayed from right to left to accomodate a locale preference or some columns might be hidden at the request of the user. Because the model does not know how the columns are laid out on screen, the given xPosition should not be considered to be a coordinate in 2D graphics space. Instead, it should be considered to be a width from the start of the first column in the model. If the column index for a given X coordinate in 2D space is required, JTable.columnAtPoint can be used instead.

  Returns:

  the index of the column; or -1 if no column is found

  See Also:

  JTable.columnAtPoint(java.awt.Point)

• getTotalColumnWidth

  int getTotalColumnWidth()

  Returns the total width of all the columns.

  Returns:

  the total computed width of all columns

• setColumnSelectionAllowed

  void setColumnSelectionAllowed(boolean flag)

  Sets whether the columns in this model may be selected.

  Parameters:

  flag - true if columns may be selected; otherwise false

  See Also:

  getColumnSelectionAllowed()

• getColumnSelectionAllowed

  boolean getColumnSelectionAllowed()

  Returns true if columns may be selected.

  Returns:

  true if columns may be selected

  See Also:

  setColumnSelectionAllowed(boolean)

• getSelectedColumns

  int[] getSelectedColumns()

  Returns an array of indicies of all selected columns.

  Returns:

  an array of integers containing the indicies of all selected columns; or an empty array if nothing is selected

• getSelectedColumnCount

  int getSelectedColumnCount()

  Returns the number of selected columns.

  Returns:

  the number of selected columns; or 0 if no columns are selected

• setSelectionModel

  void setSelectionModel(ListSelectionModel newModel)

  Sets the selection model.

  Parameters:

  newModel - a ListSelectionModel object

  See Also:

  getSelectionModel()

• getSelectionModel

  ListSelectionModel getSelectionModel()

  Returns the current selection model.

  Returns:

  a ListSelectionModel object

  setSelectionModel(javax.swing.ListSelectionModel)

• addColumnModelListener

  void addColumnModelListener(TableColumnModelListener x)

  Adds a listener for table column model events.

  Parameters:

  x - a TableColumnModelListener object

• removeColumnModelListener

  void removeColumnModelListener(TableColumnModelListener x)

  Removes a listener for table column model events.

  Parameters:

  x - a TableColumnModelListener object
