public class XJTable
extends JTable

A "smarter" JTable. Features include:

• sorting the table using the values from a column as keys
• updating the widths of the columns so they accommodate the contents to their preferred sizes.
• filling the whole viewport by default, unless told not to auto resize (see JTable.setAutoResizeMode(int).
• sizing the rows according to the preferred sizes of the renderers
• ability to hide/show columns
• ability for tab key to skip uneditable cells
• ability to get in editing mode as soon as a cell gets the focus

It uses a custom made model that stands between the table model set by the user and the GUI component. This middle model is responsible for sorting the rows.

public XJTable(TableModel model)

Method Detail

setModel

public void setModel(TableModel dataModel)

Overrides:

setModel in class JTable

newColumns

protected void newColumns()

Called when the columns have changed.

setTableHeader

public void setTableHeader(JTableHeader newTableHeader)

Overrides:

getPreferredScrollableViewportSize

public Dimension getPreferredScrollableViewportSize()

Specified by:

calculatePreferredSize

protected void calculatePreferredSize()

doLayout

public void doLayout()

Overrides:

doLayout in class JTable

getPreferredSize

public Dimension getPreferredSize()

Overrides:

getPreferredSize in class JComponent

getScrollableTracksViewportWidth

public boolean getScrollableTracksViewportWidth()

Overridden to ignore requests for this table to track the width of its containing viewport in cases where the viewport is narrower than the minimum size of the table. Where the viewport is at least as wide as the minimum size of the table, we will allow the table to resize with the viewport, but when it gets too small we stop tracking, which allows the horizontal scrollbar to appear.

Specified by:

getScrollableTracksViewportWidth in interface Scrollable

Overrides:

getScrollableTracksViewportWidth in class JTable

getScrollableTracksViewportHeight

public boolean getScrollableTracksViewportHeight()

Track parent viewport's size if it's larger than the current preferred height of the table (causes empty tables to fill in the whole area of a JScrollPane).

Specified by:

getScrollableTracksViewportHeight in interface Scrollable

Overrides:

getScrollableTracksViewportHeight in class JTable

Returns:

true if the preferred height of the table is smaller than the viewport.
