public class JXList
extends JList

Enhanced List component with support for general SwingX sorting/filtering, rendering, highlighting, rollover and search functionality. List specific enhancements include ?? PENDING JW ...

Sorting and Filtering

JXList supports sorting and filtering. Changed to use core support. Usage is very similar to J/X/Table. It provides api to apply a specific sort order, to toggle the sort order and to reset a sort. Sort sequence can be configured by setting a custom comparator.

 list.setAutoCreateRowSorter(true);
 list.setComparator(myComparator);
 list.setSortOrder(SortOrder.DESCENDING);
 list.toggleSortOder();
 list.resetSortOrder();
 

JXList provides api to access items of the underlying model in view coordinates and to convert from/to model coordinates. Note: JXList needs a specific ui-delegate - BasicXListUI and subclasses - which is aware of model vs. view coordiate systems and which controls the synchronization of selection/dataModel and sorter state. SwingX comes with a subclass for Synth.

Rendering and Highlighting

As all SwingX collection views, a JXList is a HighlighterClient (PENDING JW: formally define and implement, like in AbstractTestHighlighter), that is it provides consistent api to add and remove Highlighters which can visually decorate the rendering component.


 
 JXList list = new JXList(new Contributors());
 // implement a custom string representation, concated from first-, lastName
 StringValue sv = new StringValue() {
     public String getString(Object value) {
        if (value instanceof Contributor) {
           Contributor contributor = (Contributor) value;
           return contributor.lastName() + ", " + contributor.firstName(); 
        }
        return StringValues.TO_STRING(value);
     }
 };
 list.setCellRenderer(new DefaultListRenderer(sv); 
 // highlight condition: gold merits
 HighlightPredicate predicate = new HighlightPredicate() {
    public boolean isHighlighted(Component renderer,
                     ComponentAdapter adapter) {
       if (!(value instanceof Contributor)) return false;              
       return ((Contributor) value).hasGold();
    }
 };
 // highlight with foreground color 
 list.addHighlighter(new PainterHighlighter(predicate, goldStarPainter);      
 
 
Note: to support the highlighting this implementation wraps the ListCellRenderer set by client code with a DelegatingRenderer which applies the Highlighter after delegating the default configuration to the wrappee. As a side-effect, getCellRenderer does return the wrapper instead of the custom renderer. To access the latter, client code must call getWrappedCellRenderer.

Rollover

As all SwingX collection views, a JXList supports per-cell rollover. If enabled, the component fires rollover events on enter/exit of a cell which by default is promoted to the renderer if it implements RolloverRenderer, that is simulates live behaviour. The rollover events can be used by client code as well, f.i. to decorate the rollover row using a Highlighter.

 
 JXList list = new JXList();
 list.setRolloverEnabled(true);
 list.setCellRenderer(new DefaultListRenderer());
 list.addHighlighter(new ColorHighlighter(HighlightPredicate.ROLLOVER_ROW, 
      null, Color.RED);      
 
 

Search

As all SwingX collection views, a JXList is searchable. A search action is registered in its ActionMap under the key "find". The default behaviour is to ask the SearchFactory to open a search component on this component. The default keybinding is retrieved from the SearchFactory, typically ctrl-f (or cmd-f for Mac). Client code can register custom actions and/or bindings as appropriate.

JXList provides api to vend a renderer-controlled String representation of cell content. This allows the Searchable and Highlighters to use WYSIWYM (What-You-See-Is-What-You-Match), that is pattern matching against the actual string as seen by the user.

setAutoCreateRowSorter

public void setAutoCreateRowSorter(boolean autoCreateRowSorter)
Specifies whether a RowSorter should be created for the list whenever its model changes.

When setAutoCreateRowSorter(true) is invoked, a RowSorter is immediately created and installed on the list. While the autoCreateRowSorter property remains true, every time the model is changed, a new RowSorter is created and set as the list's row sorter.

The default value is false.

Parameters:
autoCreateRowSorter - whether or not a RowSorter should be automatically created

Returns:
the default RowSorter.

getRowSorter

public RowSorter<? extends ListModel> getRowSorter()
Returns the object responsible for sorting.

Returns:
the object responsible for sorting
Since:
1.6

setRowSorter

public void setRowSorter(RowSorter<? extends ListModel> sorter)
Sets the RowSorter. RowSorter is used to provide sorting and filtering to a JXList.

This method clears the selection and resets any variable row heights.

If the underlying model of the RowSorter differs from that of this JXList undefined behavior will result.

Parameters:
sorter - the RowSorter; null turns sorting off

configureSorterProperties

protected void configureSorterProperties()
Propagates sort-related properties from table/columns to the sorter if it is of type SortController, does nothing otherwise.


setSortable

public void setSortable(boolean sortable)
Sets "sortable" property indicating whether or not this list isSortable. Note: as of post-1.0 this property is propagated to the SortController. Whether or not a change triggers a re-sort is up to either the concrete controller implementation (the default doesn't) or client code. This behaviour is different from old SwingX style sorting.

Parameters:
sortable - boolean indicating whether or not this table supports sortable columns
See Also:
TableColumnExt.isSortable()

isSortable

public boolean isSortable()
Returns the table's sortable property.

Returns:
true if the table is sortable.

setSortsOnUpdates

public void setSortsOnUpdates(boolean sortsOnUpdates)
If true, specifies that a sort should happen when the underlying model is updated (rowsUpdated is invoked). For example, if this is true and the user edits an entry the location of that item in the view may change. The default is true.

Parameters:
sortsOnUpdates - whether or not to sort on update events

getSortsOnUpdates

public boolean getSortsOnUpdates()
Returns true if a sort should happen when the underlying model is updated; otherwise, returns false.

Returns:
whether or not to sort when the model is updated

setSortOrderCycle

public void setSortOrderCycle(SortOrder... cycle)

Sets the comparator to use for sorting.

Note: as of post-1.0 the property is propagated to the SortController, if available. Whether or not a change triggers a re-sort is up to either the concrete controller implementation (the default doesn't) or client code. This behaviour is different from old SwingX style sorting.

Parameters:
comparator - the comparator to use.

updateSortAfterComparatorChange

protected void updateSortAfterComparatorChange()
Updates the SortController's comparator, if available. Does nothing otherwise.


setRowFilter

public void setRowFilter(RowFilter<? super ListModel,? super Integer> filter)

Parameters:
filter - the filter used to determine what entries should be included

getRowFilter

public RowFilter<?,?> getRowFilter()
Returns the filter of the sorter, if available and of type SortController. Returns null otherwise.

PENDING JW: generics? had to remove return type from getSortController to make this compilable, so probably wrong.

Returns:
the filter used in the sorter.

resetSortOrder

public void resetSortOrder()
Resets sorting of all columns. Delegates to the SortController if available, or does nothing if not.

PENDING JW: method name - consistent in SortController and here.


toggleSortOrder

public void toggleSortOrder()
Toggles the sort order of the list. Delegates to the SortController if available, or does nothing if not.

The exact behaviour is defined by the SortController's toggleSortOrder implementation. Typically a unsorted list is sorted in ascending order, a sorted list's order is reversed.


setSortOrder

public void setSortOrder(SortOrder sortOrder)
Sorts the list using SortOrder. Delegates to the SortController if available, or does nothing if not.

Parameters:
sortOrder - the sort order to use.

getSortOrder

public SortOrder getSortOrder()
Returns the SortOrder. Delegates to the SortController if available, or returns SortOrder.UNSORTED if not.

Returns:
the current SortOrder

getSortController

protected SortController<? extends ListModel> getSortController()
Returns the currently active SortController. May be null if RowSorter is null or not of type SortController.

PENDING JW: swaying about hiding or not - currently the only way to make the view not configure a RowSorter of type SortController is to let this return null.

Returns:
the currently active SortController may be null

hasSortController

protected boolean hasSortController()
Returns a boolean indicating whether the table has a SortController. If true, the call to getSortController is guaranteed to return a not-null value.

Returns:
a boolean indicating whether the table has a SortController.
See Also:
getSortController()

getControlsSorterProperties

protected boolean getControlsSorterProperties()
Returns a boolean indicating whether the table configures the sorter's properties. If true, guaranteed that table's and the columns' sort related properties are propagated to the sorter. If false, guaranteed to not touch the sorter's configuration.

This implementation returns true if the sorter is of type SortController. Note: the synchronization is unidirection from the table to the sorter. Changing the sorter under the table's feet might lead to undefined behaviour.

Returns:
a boolean indicating whether the table configurers the sorter's properties.

getElementAt

public Object getElementAt(int viewIndex)
Returns the element at the given index. The index is in view coordinates which might differ from model coordinates if filtering is enabled and filters/sorters are active.

Parameters:
viewIndex - the index in view coordinates
Returns:
the element at the index
Throws:
IndexOutOfBoundsException - if viewIndex < 0 or viewIndex >= getElementCount()

getSelectedValue

public Object getSelectedValue()
Returns the value for the smallest selected cell index; the selected value when only a single item is selected in the list. When multiple items are selected, it is simply the value for the smallest selected index. Returns null if there is no selection.

This is a convenience method that simply returns the model value for getMinSelectionIndex, taking into account sorting and filtering.

Overrides:
getSelectedValue in class JList
Returns:
the first selected value
See Also:
JList.getMinSelectionIndex(), JList.getModel(), JList.addListSelectionListener(javax.swing.event.ListSelectionListener)

setSelectedValue

public void setSelectedValue(Object anObject,
                             boolean shouldScroll)
Selects the specified object from the list, taking into account sorting and filtering.

Overrides:
setSelectedValue in class JList
Parameters:
anObject - the object to select
shouldScroll - true if the list should scroll to display the selected object, if one exists; otherwise false

getSelectedValues

public Object[] getSelectedValues()
Returns an array of all the selected values, in increasing order based on their indices in the list and taking into account sourting and filtering.

Overrides:
getSelectedValues in class JList
Returns:
the selected values, or an empty array if nothing is selected
See Also:
JList.isSelectedIndex(int), JList.getModel(), JList.addListSelectionListener(javax.swing.event.ListSelectionListener)

getElementCount

public int getElementCount()
Returns the number of elements in this list in view coordinates. If filters are active this number might be less than the number of elements in the underlying model.

Returns:
number of elements in this list in view coordinates

convertIndexToModel

public int convertIndexToModel(int viewIndex)
Convert row index from view coordinates to model coordinates accounting for the presence of sorters and filters.

Parameters:
viewIndex - index in view coordinates
Returns:
index in model coordinates
Throws:
IndexOutOfBoundsException - if viewIndex < 0 or viewIndex >= getElementCount()

convertIndexToView

public int convertIndexToView(int modelIndex)
Convert index from model coordinates to view coordinates accounting for the presence of sorters and filters.

Parameters:
modelIndex - index in model coordinates
Returns:
index in view coordinates if the model index maps to a view coordinate or -1 if not contained in the view.

getWrappedModel

@Deprecated
public ListModel getWrappedModel()
Deprecated. no longer used - custom ui-delegate does-the-right-thing when accessing elements.

Returns:
the underlying model, same as getModel().

setModel

public void setModel(ListModel model)
Sets the model that represents the contents or "value" of the list, notifies property change listeners, and then clears the list's selection.

This is a JavaBeans bound property.

Sets the underlying data model. Note that if isFilterEnabled you must call getWrappedModel to access the model given here. In this case getModel returns a wrapper around the data!

Overrides:
setModel in class JList
Parameters:
model - the data model for this list.
See Also:
JList.getModel(), JList.clearSelection()

getComponentAdapter

protected ComponentAdapter getComponentAdapter()
Returns:
the unconfigured ComponentAdapter.

getComponentAdapter

protected ComponentAdapter getComponentAdapter(int index)
Convenience to access a configured ComponentAdapter. Note: the column index of the configured adapter is always 0.

Parameters:
index - the row index in view coordinates, must be valid.
Returns:
the configured ComponentAdapter.

setHighlighters

public void setHighlighters(Highlighter... highlighters)
Sets the Highlighters to the table, replacing any old settings. None of the given Highlighters must be null.

This is a bound property.

Note: as of version #1.257 the null constraint is enforced strictly. To remove all highlighters use this method without param.

Parameters:
highlighters - zero or more not null highlighters to use for renderer decoration.
Throws:
NullPointerException - if array is null or array contains null values.
See Also:
getHighlighters(), addHighlighter(Highlighter), removeHighlighter(Highlighter)

getHighlighters

public Highlighter[] getHighlighters()
Returns the Highlighters used by this table. Maybe empty, but guarantees to be never null.

Returns:
the Highlighters used by this table, guaranteed to never null.
See Also:
setHighlighters(Highlighter[])

addHighlighter

public void addHighlighter(Highlighter highlighter)
Appends a Highlighter to the end of the list of used Highlighters. The argument must not be null.

Parameters:
highlighter - the Highlighter to add, must not be null.
Throws:
NullPointerException - if Highlighter is null.
See Also:
removeHighlighter(Highlighter), setHighlighters(Highlighter[])

removeHighlighter

public void removeHighlighter(Highlighter highlighter)
Removes the given Highlighter.

Does nothing if the Highlighter is not contained.

Parameters:
highlighter - the Highlighter to remove.
See Also:
addHighlighter(Highlighter), setHighlighters(Highlighter...)

getCompoundHighlighter

protected CompoundHighlighter getCompoundHighlighter()
Returns the CompoundHighlighter assigned to the table, null if none. PENDING: open up for subclasses again?.

Returns:
the CompoundHighlighter assigned to the table.

getHighlighterChangeListener

protected ChangeListener getHighlighterChangeListener()
Returns the ChangeListener to use with highlighters. Lazily creates the listener.

Returns:
the ChangeListener for observing changes of highlighters, guaranteed to be not-null

createHighlighterChangeListener

protected ChangeListener createHighlighterChangeListener()
Creates and returns the ChangeListener observing Highlighters.

Here: repaints the table on receiving a stateChanged.

Returns:
the ChangeListener defining the reaction to changes of highlighters.

getStringValueRegistry

protected StringValueRegistry getStringValueRegistry()
Returns the StringValueRegistry which defines the string representation for each cells. This is strictly for internal use by the table, which has the responsibility to keep in synch with registered renderers.

Currently exposed for testing reasons, client code is recommended to not use nor override.

Returns:

createDefaultStringValueRegistry

protected StringValueRegistry createDefaultStringValueRegistry()
Creates and returns the default registry for StringValues.

Returns:
the default registry for StringValues.

getStringAt

public String getStringAt(int row)
Returns the string representation of the cell value at the given position.

Parameters:
row - the row index of the cell in view coordinates
Returns:
the string representation of the cell value as it will appear in the table.

createDefaultCellRenderer

protected ListCellRenderer createDefaultCellRenderer()
Creates and returns the default cell renderer to use. Subclasses may override to use a different type. Here: returns a DefaultListRenderer.

Returns:
the default cell renderer to use with this list.

getCellRenderer

public ListCellRenderer getCellRenderer()
Returns the object responsible for painting list items.

Overridden to return the delegating renderer which is wrapped around the original to support highlighting. The returned renderer is of type DelegatingRenderer and guaranteed to not-null

Overrides:
getCellRenderer in class JList
Returns:
the value of the cellRenderer property
See Also:
setCellRenderer(ListCellRenderer), JXList.DelegatingRenderer

getWrappedCellRenderer

public ListCellRenderer getWrappedCellRenderer()
Returns the renderer installed by client code or the default if none has been set.

Returns:
the wrapped renderer.
See Also:
setCellRenderer(ListCellRenderer)

setCellRenderer

public void setCellRenderer(ListCellRenderer renderer)
Sets the delegate that is used to paint each cell in the list. The job of a cell renderer is discussed in detail in the class level documentation.

If the prototypeCellValue property is non-null, setting the cell renderer also causes the fixedCellWidth and fixedCellHeight properties to be re-calculated. Only one PropertyChangeEvent is generated however - for the cellRenderer property.

The default value of this property is provided by the ListUI delegate, i.e. by the look and feel implementation.

This is a JavaBeans bound property.

Overridden to wrap the given renderer in a DelegatingRenderer to support highlighting.

Note: the wrapping implies that the renderer returned from the getCellRenderer is not the renderer as given here, but the wrapper. To access the original, use getWrappedCellRenderer.

Overrides:
setCellRenderer in class JList
Parameters:
renderer - the ListCellRenderer that paints list cells
See Also:
getWrappedCellRenderer(), getCellRenderer()

invalidateCellSizeCache

public void invalidateCellSizeCache()
Invalidates cell size caching in the ui delegate. May do nothing if there's no safe (i.e. without reflection) way to message the delegate.

This implementation calls the corresponding method on BasicXListUI if available, does nothing otherwise.


updateUI

public void updateUI()
Resets the ListUI property by setting it to the value provided by the current look and feel. If the current cell renderer was installed by the developer (rather than the look and feel itself), this also causes the cell renderer and its children to be updated, by calling SwingUtilities.updateComponentTreeUI on it.

Overridden to update renderer and Highlighters.

Overrides:
updateUI in class JList
See Also:
UIManager.getUI(javax.swing.JComponent), SwingUtilities.updateComponentTreeUI(java.awt.Component)

getUIClassID

public String getUIClassID()
Description copied from class: javax.swing.JList
Returns "ListUI", the UIDefaults key used to look up the name of the javax.swing.plaf.ListUI class that defines the look and feel for this component.

Overrides:
getUIClassID in class JList
Returns:
the string "ListUI"
See Also:
JComponent.getUIClassID(), UIDefaults.getUI(javax.swing.JComponent)

updateHighlighterUI

protected void updateHighlighterUI()
Updates highlighter after updateUI changes.
