 public JTableHeader(TableColumnModel cm)

 public JTable getTable()

 public void setReorderingAllowed(boolean b)

Sets whether the user can drag column headers to reorder columns.

Parameters:

flag - true if the table view should allow reordering

See Also:

getReorderingAllowed

 public boolean getReorderingAllowed()

Returns true if the receiver allows the user to rearrange columns by dragging their headers, false otherwise. The default is true. You can rearrange columns programmatically regardless of this setting.

Returns:

true if the receiver allows the user to rearrange columns by dragging their headers, false otherwise

See Also:

setReorderingAllowed

 public void setResizingAllowed(boolean b)

Sets whether the user can resize columns by dragging between headers.

Parameters:

flag - true if table view should allow resizing

See Also:

getResizingAllowed

 public boolean getResizingAllowed()

Returns true if the receiver allows the user to resize columns by dragging between their headers, false otherwise. The default is true. You can resize columns programmatically regardless of this setting.

Returns:

true if the receiver allows the user to resize columns by dragging between their headers, false otherwise.

See Also:

 public int getDraggedColumn()

Returns the index of the dragged column, if and only if a drag is in process.

Returns:

the index of the dragged column, if and only if a drag is in process, otherwise returns -1

See Also:

getDraggedDistance

 public int getDraggedDistance()

Returns the column's horizontal distance from its original position, if and only if a drag is in process. Otherwise, the the return value is meaningless.

Returns:

the column's horizontal distance from its original position, if and only if a drag is in process

See Also:

getDraggedColumn

 public int getResizingColumn()

Returns the index of the resizing column. If no column is being resized this method returns -1.

Returns:

the index of the resizing column

 public void setUpdateTableInRealTime(boolean flag)

Sets whether the body of the table updates in real time when a column is resized or dragged.

Parameters:

flag - true if tableView should update the body of the table in real time

See Also:

getUpdateTableInRealTime

 public boolean getUpdateTableInRealTime()

Returns true if the receiver updates the body of the table view in real time when a column is resized or dragged. User can set this flag to false to speed up the table's response to user resize or drag actions. The default is true.

Returns:

true if the table updates in real time
