All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, EventListener, Accessible, TableColumnModelListener

public class DfcTableHeader
extends JTableHeader

Extended JTable header component used by DfcTable. Uses ButtonHeaderRenderer as the default renderer, enables sorting of tables using SortedTableModel by handling clicks on column headers and support auto sizing when the user double-clicks the resize area of a column header.

Field Detail

table

protected JTable table

pressedColumn

protected int pressedColumn

Constructor Detail

DfcTableHeader

public DfcTableHeader(JTable table)

Method Detail

getPressedColumn

public int getPressedColumn()

The currently pressed column index (in model space) or -1 if no header is currently pressed. Can be used by header renderers to make column behave like a button.

canResize

protected boolean canResize(TableColumn column)

Test if a column may be resized.

getResizingColumn

protected TableColumn getResizingColumn(Point p)

See getResizingColumn(Point,int).

getResizingColumn

protected TableColumn getResizingColumn(Point p,
                                        int column)

Get the column (if any) that a given point is in the resize zone of. This logic is ripped from BasicTableHeaderUI's MouseInputHandler class.

Parameters:

p - The point to test.

column - The column to test.

Returns:

The column instance of p lies in the resize zone, null if not.

createDefaultRenderer

protected TableCellRenderer createDefaultRenderer()

Override to use ButtonHeaderRenderer as the header renderer.

Overrides:

createDefaultRenderer in class JTableHeader

processMouseEvent

protected void processMouseEvent(MouseEvent e)

Handles mouse clicks in header cells to change sort order and auto column sizing when double-clicking in header resize zone.

Overrides:

processMouseEvent in class JComponent
