All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, EventListener, Accessible, TableColumnModelListener, TableModelListener

public class ResizeableTableHeader
extends JTableHeader
implements TableModelListener

This subclass of JTableHeader extends a JTable with the ability to resize a column to fit all its content on double click on the right end of the column's header cell.

Note that you have to set the tableheader's columnmodel to the columnmodel of the table. See example for usage:

 JTable table;
 ResizeableTableHeader tableHeader;

 // create new table
 table= new JTable();
 // create new ResizableTableHeader with the table's ColumnModel
 tableHeader =  new ResizeableTableHeader(table.getColumnModel());
 // set the new header for the table
 table.setTableHeader(tableHeader);
 

Or for the one line fans

 // create new table
 JTable table= new JTable();
 table.setTableHeader(new ResizeableTableHeader(table.getColumnModel()));

Constructor Detail

ResizeableTableHeader

public ResizeableTableHeader()

Constructs a ResizeableTableHeader with a default TableColumnModel.

ResizeableTableHeader

public ResizeableTableHeader(TableColumnModel cm)

Constructs a ResizeableTableHeader which is initialized with cm as the column model. If cm is null this method will initialize the table header with a default TableColumnModel.

Parameters:

cm - the column model for the table

Method Detail

setTable

public void setTable(JTable table)

Sets the table associated with this header. Also adds a TableModelListener to the table's TableModel to allow resizing of columns if data of table changed.

Overrides:

setTable in class JTableHeader

Parameters:

table - the new table

setAutoResizingEnabled

public void setAutoResizingEnabled(boolean autoResizingEnabled)

Sets whether columns are resized on table model events.

Parameters:

autoResizingEnabled - true if columns are resized automatically

See Also:

getAutoResizingEnabled()

getAutoResizingEnabled

public boolean getAutoResizingEnabled()

Returns true if auto resizing is enabled.

Returns:

the autoResizingEnabled property

See Also:

setAutoResizingEnabled(boolean)

setIncludeHeaderWidth

public void setIncludeHeaderWidth(boolean includeHeaderWidth)

Sets whether the header's width are included on calculation

Parameters:

includeHeaderWidth - true if the headers are included

See Also:

getIncludeHeaderWidth()

getIncludeHeaderWidth

public boolean getIncludeHeaderWidth()

Returns true, if the header's width are

Returns:

the setIncludeHeaderWidth property

See Also:

resizeColumn

public void resizeColumn(TableColumn column)

Resizes the given column to fit all its content.

Parameters:

column - The TableColumn to resize.

resizeAllColumns

public void resizeAllColumns()

Resizes all columns to fit all their content.

setColumnWidths

public void setColumnWidths(TableColumn column,
                            int preferredWidth,
                            int minWidth,
                            int maxWidth)

Sets preferred width, the minimum and maximum width for a given column. The minimum and maximum widths are the bounds for the preferred width. If the preferred width is not in the region of minmum and maximum, it will be adjusted. Also the user cannot resize columns out of this bounds by moving the edge or double clicking it. If a width is set to -1, no change is made to this value.

Parameters:

column - The TableColumn to change.

preferredWidth - The preferred width of the column.

minWidth - The minimum width of the column.

maxWidth - The maximum width of the column.

See Also:

setAllColumnWidths(int preferredWidth, int minWidth, int maxWidth)

                               int maxWidth)

Sets preferred width, the minimum and maximum width for all columns. See setColumnWidth() for further details.

Parameters:

preferredWidth - The preferred width of the column.

minWidth - The minimum width of the column.

maxWidth - The maximum width of the column.

See Also:

setColumnWidths(javax.swing.table.TableColumn column,int preferredWidth, int minWidth, int maxWidth)

tableChanged

public void tableChanged(TableModelEvent e)
