public class JXTableHeader
extends JTableHeader
implements TableColumnModelExtListener

TableHeader with extended functionality if associated Table is of type JXTable.

The enhancements:

• supports pluggable handler to control user interaction for sorting. The default handler toggles sort order on mouseClicked on the header of the column to sort. On shift-mouseClicked, it resets any column sorting. Both are done by invoking the corresponding methods of JXTable, toggleSortOrder(int) and resetSortOrder()
• uses ColumnHeaderRenderer which can show the sort icon
• triggers column pack (== auto-resize to exactly fit the contents) on double-click in resize region.
• auto-scrolls if column is dragged outside visible rectangle. This feature is enabled if the autoscrolls property is true. The default is false (because of Issue #788-swingx which still isn't fixed for jdk1.6).
• listens to TableColumn propertyChanges to update itself accordingly.

Constructor Detail

JXTableHeader

public JXTableHeader()

Constructs a JTableHeader with a default TableColumnModel.

See Also:

JTableHeader.createDefaultColumnModel()

JXTableHeader

public JXTableHeader(TableColumnModel columnModel)

Constructs a JTableHeader 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:

columnModel - the column model for the table

See Also:

JTableHeader.createDefaultColumnModel()

Method Detail

setTable

public void setTable(JTable table)

Sets the associated JTable. Enables enhanced header features if table is of type JXTable.

PENDING: who is responsible for synching the columnModel?

Overrides:

setTable in class JTableHeader

Parameters:

table - the new table

columnPropertyChange

public void columnPropertyChange(PropertyChangeEvent event)

Implementing TableColumnModelExt: listening to column property changes. Here: triggers a resizeAndRepaint on every propertyChange which doesn't already fire a "normal" columnModelEvent.

Specified by:

columnPropertyChange in interface TableColumnModelExtListener

Parameters:

event - change notification from a contained TableColumn.

See Also:

isColumnEvent(PropertyChangeEvent)

isColumnEvent

protected boolean isColumnEvent(PropertyChangeEvent event)

Parameters:

event - the PropertyChangeEvent received as TableColumnModelExtListener.

Returns:

a boolean to decide whether the same event triggers a base columnModelEvent.

getToolTipText

public String getToolTipText(MouseEvent event)

overridden to respect the column tooltip, if available.

Overrides:

getToolTipText in class JTableHeader

Parameters:

event - the location of the event identifies the proper renderer and, therefore, the proper tip

Returns:

the column tooltip of the column at the mouse position if not null or super if not available.

getColumnToolTipText

protected String getColumnToolTipText(MouseEvent event)

Parameters:

event - the mouseEvent representing the mouse location.

Returns:

the column tooltip of the column below the mouse location, or null if not available.

getXTable

public JXTable getXTable()

getCellRenderer

public TableCellRenderer getCellRenderer(int columnIndex)

Returns the TableCellRenderer used for rendering the headerCell of the column at columnIndex.

Parameters:

columnIndex - the index of the column

Returns:

the renderer.

getPreferredSize

public Dimension getPreferredSize()

Overridden to adjust for a minimum height as returned by #getMinimumHeight.

Overrides:

getPreferredSize in class JComponent

Returns:

the value of the preferredSize property

See Also:

JComponent.setPreferredSize(java.awt.Dimension), ComponentUI

getPreferredSize

protected Dimension getPreferredSize(Dimension pref)

Hack around #334-swingx: super doesnt measure all headerRenderers for prefSize. This hack does and adjusts the height of the given Dimension to be equal to the max fo all renderers.

Parameters:

pref - the adjusted preferred size respecting all renderers size requirements.

getMinimumHeight

protected int getMinimumHeight(int height)

Allows to enforce a minimum heigth in the getXXSize methods. Here: jumps in if the input height is 0, then measures the cell renderer component with a dummy value.

Parameters:

height - the prefHeigth as calcualated by super.

Returns:

a minimum height for the preferredSize.

updateUI

public void updateUI()

Notification from the UIManager that the look and feel (L&F) has changed. Replaces the current UI object with the latest version from the UIManager.

Overridden to update the default renderer.

Overrides:

updateUI in class JTableHeader

See Also:

preUpdateRendererUI(), postUpdateRendererUI(TableCellRenderer), ColumnHeaderRenderer

preUpdateRendererUI

protected TableCellRenderer preUpdateRendererUI()

Prepares the default renderer and internal state for updateUI. Returns the default renderer set when entering this method. Called from updateUI before calling super.updateUI to allow UIDelegate to cleanup, if necessary. This implementation does so by restoring the header's default renderer to the ColumnHeaderRenderer's delegate.

Returns:

the current default renderer

See Also:

updateUI()

postUpdateRendererUI

protected void postUpdateRendererUI(TableCellRenderer oldRenderer)

Cleans up after the UIDelegate has updated the default renderer. Called from updateUI after calling super.updateUI. This implementation wraps a UIResource default renderer into a ColumnHeaderRenderer.

Parameters:

oldRenderer - the default renderer before updateUI

See Also:

updateUI()

setDraggedDistance

public void setDraggedDistance(int distance)

Sets the header's draggedDistance to distance.

Overridden to scroll the table to keep the dragged column visible. This side-effect is enabled only if the header's autoscroll property is true and the associated table is of type JXTable.

The autoscrolls is disabled by default. With or without - core issue #6503981 has weird effects (for jdk 1.6 - 1.6u3) on a plain JTable as well as a JXTable, fixed in 1.6u4.

Overrides:

setDraggedDistance in class JTableHeader

Parameters:

distance - the distance dragged

getDraggedColumn

public TableColumn getDraggedColumn()

Returns the the dragged column if and only if, a drag is in process and the column is visible, otherwise returns null.

Overrides:

getDraggedColumn in class JTableHeader

Returns:

the dragged column, if a drag is in process and the column is visible, otherwise returns null

See Also:

JTableHeader.getDraggedDistance()

getSortGestureRecognizer

public JXTableHeader.SortGestureRecognizer getSortGestureRecognizer()

Lazily creates and returns the SortGestureRecognizer.

Returns:

the SortGestureRecognizer used in Headerlistener.

setSortGestureRecognizer

public void setSortGestureRecognizer(JXTableHeader.SortGestureRecognizer recognizer)

Set the SortGestureRecognizer for use in the HeaderListener.

Parameters:

recognizer - the recognizer to use in HeaderListener.

createSortGestureRecognizer

protected JXTableHeader.SortGestureRecognizer createSortGestureRecognizer()

creates and returns the default SortGestureRecognizer.

Returns:

the SortGestureRecognizer used in Headerlistener.

installHeaderListener

protected void installHeaderListener()

uninstallHeaderListener

protected void uninstallHeaderListener()
