public class TableHeader

extends Component

The TableHeader class is used by the ScrollPane for drawing the column headers of a table. It shares the TableModel of its companion Table object.

Constructor Summary

TableHeader(TableModel model_)
Constructs a table of numRows_ and numColumns_ of empty cells using a DefaultTableModel.

Method Summary

void	debug(int level_)
void	draw() To be implemented by concrete subclasses.
int	getHeight()
Dimension	getSize() We pretend that the table header is two rows in height so that the box gets drawn correctly.
int	getWidth()
boolean	isFocusTraversable() Indicates whether this component can be traversed using Tab or Shift-Tab keyboard focus traversal.
Dimension	minimumSize()
void	requestFocus() This method should be invoked by all subclasses of Component which override this method; because this method generates the FOCUS_GAINED event when the component gains the keyboard focus.
void	setModel(TableModel model_)

Constructor Detail

TableHeader

public TableHeader(TableModel model_)

Constructs a table of numRows_ and numColumns_ of empty cells using a DefaultTableModel.

Method Detail

setModel

public void setModel(TableModel model_)

isFocusTraversable

public boolean isFocusTraversable()

Description copied from class: Component

Indicates whether this component can be traversed using Tab or Shift-Tab keyboard focus traversal. If this method returns "false" it can still request focus using requestFocus(), but it will not automatically be assigned focus during keyboard focus traversal.

Overrides:

isFocusTraversable in class Component

requestFocus

public void requestFocus()

Description copied from class: Component

This method should be invoked by all subclasses of Component which override this method; because this method generates the FOCUS_GAINED event when the component gains the keyboard focus.

Overrides:

requestFocus in class Component

draw

public void draw()

Description copied from class: Component

To be implemented by concrete subclasses.

Specified by:

draw in class Component

getSize

public Dimension getSize()

We pretend that the table header is two rows in height so that the box gets drawn correctly.

Specified by:

getSize in class Component

minimumSize

public Dimension minimumSize()

Specified by:

minimumSize in class Component

getWidth

public int getWidth()

Specified by:

getWidth in class Component

getHeight

public int getHeight()

Specified by:

getHeight in class Component

debug

public void debug(int level_)
