Method Summary
voidaddColumn(TableColumn column)
Adds a column to the model.

Registers a listener with the model, so that it will receive {@link TableColumnModelEvent} notifications.
TableColumngetColumn(int columnIndex)
Returns the TableColumn at the specified index.
intgetColumnCount()
Returns the number of columns in the model.
intgetColumnIndex(Object identifier)
Returns the index of the {@link TableColumn} with the given identifier.
intgetColumnIndexAtX(int xPosition)
Returns the index of the column that contains the specified x-coordinate, assuming that:
  • column zero begins at position zero;
  • all columns appear in order;
  • individual column widths are taken into account, but the column margin is ignored.
If no column contains the specified position, this method returns -1.
intgetColumnMargin()
Returns the column margin.
Enumeration<TableColumn>getColumns()
Returns an enumeration of the columns in the model.
booleangetColumnSelectionAllowed()
Returns true if column selection is allowed, and false if column selection is not allowed.
intgetSelectedColumnCount()
Returns the number of selected columns in the model.
int[]getSelectedColumns()
getSelectedColumns
ListSelectionModelgetSelectionModel()
Returns the selection model used to track table column selections.
intgetTotalColumnWidth()
Returns total width of all the columns in the model, ignoring the column margin (see {@link #getColumnMargin()}).
voidmoveColumn(int columnIndex, int newIndex)
Moves a column.
voidremoveColumn(TableColumn column)
Removes a column from the model.
voidremoveColumnModelListener(TableColumnModelListener listener)
Deregisters a listener, so that it will no longer receive {@link TableColumnModelEvent} notifications.
voidsetColumnMargin(int margin)
Sets the column margin and sends a {@link ChangeEvent} to all registered {@link TableColumnModelListener}s registered with the model.
voidsetColumnSelectionAllowed(boolean allowed)
Sets the flag that indicates whether or not column selection is allowed.
voidsetSelectionModel(ListSelectionModel model)
Sets the selection model that will be used to keep track of the selected columns.
