@JavaBean public class JXTreeTable extends JXTable

JXTreeTable is a specialized table consisting of a single column in which to display hierarchical data, and any number of other columns in which to display regular data. The interface for the data model used by a JXTreeTable is TreeTableModel. It extends the TreeModel interface to allow access to cell data by column indices within each node of the tree hierarchy.

The most straightforward way create and use a JXTreeTable, is to first create a suitable data model for it, and pass that to a JXTreeTable constructor, as shown below: 

  TreeTableModel  treeTableModel = new FileSystemModel(); // any TreeTableModel
  JXTreeTable     treeTable = new JXTreeTable(treeTableModel);
  JScrollPane     scrollpane = new JScrollPane(treeTable);
See JTable for an explanation of why putting the treetable inside a scroll pane is necessary.

A single treetable model instance may be shared among more than one JXTreeTable instances. To access the treetable model, always call getTreeTableModel and setTreeTableModel. JXTreeTable wraps the supplied treetable model inside a private adapter class to adapt it to a TableModel. Although the model adapter is accessible through the getModel method, you should avoid accessing and manipulating it in any way. In particular, each model adapter instance is tightly bound to a single table instance, and any attempt to share it with another table (for example, by calling setModel) will throw an IllegalArgumentException! Note:

This implementation is basically as hacky as the very first version more than a decaded ago: the renderer of the hierarchical column is a JXTree which is trickst into painting a single row at the position of the table cell. TreeModel changes must be adapted to TableModel changes after the tree received them, that is the TableModel events are asynchronous as compared to their base trigger. As a consequence, the adapted TableModel doesn't play nicely when shared in other J/X/Tables (f.i. used as rowHeader - see http://java.net/jira/browse/SWINGX-1529)

    • setSortable

      public void setSortable(boolean sortable)
      Sets "sortable" property indicating whether or not this table supports sortable columns. If sortable is true then sorting will be enabled on all columns whose sortable property is true. If sortable is false then sorting will be disabled for all columns, regardless of each column's individual sorting property. The default is true.

      Note: as of post-1.0 this property is propagated to the SortController if controlsSorterProperties is true. 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.

      Overridden to do nothing. TreeTable is not sortable because there is no equivalent to RowSorter (which is targeted to linear structures) for hierarchical data.

      Overrides:
      setSortable in class JXTable
      Parameters:
      sortable - boolean indicating whether or not this table supports sortable columns

    • setRowSorter

      public void setRowSorter(RowSorter<? extends TableModel> sorter)

      Overridden propagate sort-related properties to the sorter after calling super, if the given RowSorter is of type SortController. Does nothing additional otherwise.

      protected void superSetAutoCreateRowSorter(boolean autoCreateRowSorter)
      Hook into super's setAutoCreateRowSorter for use in sub-classes which want to experiment with tree table sorting/filtering.

      NOTE: While subclasses may use this method to allow access to super that usage alone will not magically turn sorting/filtering on! They have to implement an appropriate RowSorter/SortController as well. This is merely a hook to hang themselves, as requested in Issue #479-swingx

      Parameters:

    • setEnabled

      public void setEnabled(boolean enabled)

      Overridden to keep the tree's enabled in synch.

      Overrides:
      setEnabled in class JComponent

    • setSelectionBackground

      public void setSelectionBackground(Color selectionBackground)

      Overridden because super throws NPE on null param.

      Overridden to keep the tree's selectionBackground in synch.

      Overrides:
      setSelectionBackground in class JXTable

    • setSelectionForeground

      public void setSelectionForeground(Color selectionForeground)

      Overrides:
      setSelectionForeground in class JXTable

    • editCellAt

      public boolean editCellAt(int row, int column, EventObject e)
      Overriden to invoke repaint for the particular location if the column contains the tree. This is done as the tree editor does not fill the bounds of the cell, we need the renderer to paint the tree in the background, and then draw the editor over it. You should not need to call this method directly.

      Additionally, there is tricksery involved to expand/collapse the nodes.

      overridden to install a custom editor remover.

      Overrides:
      editCellAt in class JXTable

    • processMouseEvent

      protected void processMouseEvent(MouseEvent e)
      Overridden to enable hit handle detection a mouseEvent which triggered a expand/collapse.
      Overrides:
      processMouseEvent in class JComponent

    • getTreeTableHacker

      protected JXTreeTable.TreeTableHacker getTreeTableHacker()

    • createTreeTableHacker

      protected JXTreeTable.TreeTableHacker createTreeTableHacker()
      Hacking around various issues. Subclass and let it return your favourite. The current default is TreeTableHackerExt5 (latest evolution to work around #1230), the old long-standing default was TreeTableHackerExt3. If you experience problems with the latest, please let us know.
      Returns:

    • processMouseMotionEvent

      protected void processMouseMotionEvent(MouseEvent e)
      Overrides:
      processMouseMotionEvent in class JComponent

    • hackAroundDragEnabled

      protected boolean hackAroundDragEnabled(MouseEvent me)
      Decides whether we want to apply the hack for #168-jdnc. here: returns true if dragEnabled() and a client property with key DRAG_HACK_FLAG_KEY has a value of boolean true.

      Note: this is updated for 1.6, as the intermediate system property for enabled drag support is useless now (it's the default)

      Parameters:
      me - the mouseEvent that triggered a editCellAt
      Returns:
      true if the hack should be applied.

    • getEditingRow

      public int getEditingRow()
      Overridden to provide a workaround for BasicTableUI anomaly. Make sure the UI never tries to resize the editor. The UI currently uses different techniques to paint the renderers and editors. So, overriding setBounds() is not the right thing to do for an editor. Returning -1 for the editing row in this case, ensures the editor is never painted.
      Overrides:
      getEditingRow in class JTable

    • setTreeTableModel

      public void setTreeTableModel(TreeTableModel treeModel)
      Sets the data model for this JXTreeTable to the specified TreeTableModel. The same data model may be shared by any number of JXTreeTable instances.
      Parameters:
      treeModel - data model for this JXTreeTable

    • getTreeTableModel

      public TreeTableModel getTreeTableModel()
      Returns the underlying TreeTableModel for this JXTreeTable.
      Returns:
      the underlying TreeTableModel for this JXTreeTable

    • setModel

      public final void setModel(TableModel tableModel)

      Overrides superclass version to make sure that the specified TableModel is compatible with JXTreeTable before invoking the inherited version.

      Because JXTreeTable internally adapts an TreeTableModel to make it a compatible TableModel, this method should never be called directly. Use setTreeTableModel instead.

      While it is possible to obtain a reference to this adapted version of the TableModel by calling JTable.getModel(), any attempt to call setModel() with that adapter will fail because the adapter might have been bound to a different JXTreeTable instance. If you want to extract the underlying TreeTableModel, which, by the way, can be shared, use getTreeTableModel instead

      .
      Overrides:
      setModel in class JXTable
      Parameters:
      tableModel - must be a TreeTableModelAdapter
      Throws:
      IllegalArgumentException - if the specified tableModel is not an instance of TreeTableModelAdapter

    • tableChanged

      public void tableChanged(TableModelEvent e)
      Description copied from class: JXTable

      Overridden to update internal state related to enhanced functionality and hack around core bugs.

      • re-calculate intialize column width and preferred scrollable size after a structureChanged if autocreateColumnsFromModel is true.

      • core bug #6791934 logic to force revalidate if appropriate
      Specified by:
      tableChanged in interface TableModelListener
      Overrides:
      tableChanged in class JXTable

    • setRowHeight

      public final void setRowHeight(int row, int rowHeight)
      Throws UnsupportedOperationException because variable height rows are not supported.
      Overrides:
      setRowHeight in class JTable
      Parameters:
      row - ignored
      rowHeight - ignored
      Throws:
      UnsupportedOperationException - because variable height rows are not supported

    • setRowHeight

      public void setRowHeight(int rowHeight)
      Sets the row height for this JXTreeTable and forwards the row height to the renderering tree.
      Overrides:
      setRowHeight in class JXTable
      Parameters:
      rowHeight - height of a row.
      See Also:

      protected void adjustTreeRowHeight(int tableRowHeight)
      Forwards tableRowHeight to tree.
      Parameters:
      tableRowHeight - height of a row.

    • adjustTableRowHeight

      protected void adjustTableRowHeight(int treeRowHeight)
      Forwards treeRowHeight to table. This is for completeness only: the rendering tree is under our total control, so we don't expect any external call to tree.setRowHeight.
      Parameters:
      treeRowHeight - height of a row.

    • columnMarginChanged

      public void columnMarginChanged(ChangeEvent e)

      Overridden to support enhanced auto-resize behaviour enabled and necessary.

      Overridden to adjust the renderer's size.

      Specified by:
      columnMarginChanged in interface TableColumnModelListener
      Overrides:
      columnMarginChanged in class JXTable
      See Also:

    • setSelectionMode

      public void setSelectionMode(int mode)

      Overridden to ensure that private renderer state is kept in sync with the state of the component. Calls the inherited version after performing the necessary synchronization. If you override this method, make sure you call this version from your version of this method.

      This version maps the selection mode used by the renderer to match the selection mode specified for the table. Specifically, the modes are mapped as follows: 

        ListSelectionModel.SINGLE_INTERVAL_SELECTION: TreeSelectionModel.CONTIGUOUS_TREE_SELECTION;
  ListSelectionModel.MULTIPLE_INTERVAL_SELECTION: TreeSelectionModel.DISCONTIGUOUS_TREE_SELECTION;
  any other (default): TreeSelectionModel.SINGLE_TREE_SELECTION;
      Overrides:
      setSelectionMode in class JTable
      Parameters:
      mode - any of the table selection modes

    • prepareRenderer

      public Component prepareRenderer(TableCellRenderer renderer, int row, int column)
      Returns the decorated Component used as a stamp to render the specified cell. Overrides superclass version to provide support for cell decorators.

      Adjusts component orientation (guaranteed to happen before applying Highlighters).

      Per-column highlighters contained in TableColumnExt.getHighlighters() are applied to the renderer after the table highlighters.

      TODO kgs: interaction of search highlighter and column highlighters

      Note: DefaultTableCellRenderer and subclasses require a hack to play nicely with Highlighters because it has an internal "color memory" in setForeground/setBackground. The hack is applied in resetDefaultTableCellRendererColors which is called after super.prepareRenderer and before applying the Highlighters. The method is called always and for all renderers.

      Overridden to decorate the tree's renderer after calling super. At that point, it is only the tree itself that has been decorated.

      Overrides:
      prepareRenderer in class JXTable
      Parameters:
      renderer - the TableCellRenderer to prepare
      row - the row of the cell to render, where 0 is the first row
      column - the column of the cell to render, where 0 is the first column
      Returns:
      the Component used as a stamp to render the specified cell
      See Also:

    • applyRenderer

      protected Component applyRenderer(Component component, ComponentAdapter adapter)
      Performs configuration of the tree's renderer if the adapter's column is the hierarchical column, does nothing otherwise.

      Note: this is legacy glue if the treeCellRenderer is of type DefaultTreeCellRenderer. In that case the renderer's background/foreground/Non/Selection colors are set to the tree's background/foreground depending on the adapter's selection state. Does nothing if the treeCellRenderer is backed by a ComponentProvider.

      Parameters:
      component - the rendering component
      adapter - component data adapter
      Throws:
      NullPointerException - if the specified component or adapter is null

      public void setLargeModel(boolean newValue)
      Specifies whether the UI should use a large model. (Not all UIs will implement this.)

      NOTE: this method is exposed for completeness - currently it's not recommended to use a large model because there are some issues (not yet fully understood), namely issue #25-swingx, and probably #270-swingx.

      Parameters:
      newValue - true to suggest a large model to the UI

    • addTreeExpansionListener

      public void addTreeExpansionListener(TreeExpansionListener tel)
      Adds a listener for TreeExpansion events.
      Parameters:
      tel - a TreeExpansionListener that will be notified when a tree node is expanded or collapsed

    • removeTreeExpansionListener

      public void removeTreeExpansionListener(TreeExpansionListener tel)
      Removes a listener for TreeExpansion events.
      Parameters:
      tel - the TreeExpansionListener to remove

    • addTreeSelectionListener

      public void addTreeSelectionListener(TreeSelectionListener tsl)
      Adds a listener for TreeSelection events. TODO (JW): redirect event source to this.
      Parameters:
      tsl - a TreeSelectionListener that will be notified when a tree node is selected or deselected

    • removeTreeSelectionListener

      public void removeTreeSelectionListener(TreeSelectionListener tsl)
      Removes a listener for TreeSelection events.
      Parameters:
      tsl - the TreeSelectionListener to remove

    • addTreeWillExpandListener

      public void addTreeWillExpandListener(TreeWillExpandListener tel)
      Adds a listener for TreeWillExpand events. TODO (JW): redirect event source to this.
      Parameters:
      tel - a TreeWillExpandListener that will be notified when a tree node will be expanded or collapsed

    • removeTreeWillExpandListener

      public void removeTreeWillExpandListener(TreeWillExpandListener tel)
      Removes a listener for TreeWillExpand events.
      Parameters:
      tel - the TreeWillExpandListener to remove

    • getTreeSelectionModel

      public TreeSelectionModel getTreeSelectionModel()
      Returns the selection model for the tree portion of the this treetable.
      Returns:
      selection model for the tree portion of the this treetable

    • sizeColumnsToFit

      public void sizeColumnsToFit(int resizingColumn)
      Overriden to invoke supers implementation, and then, if the receiver is editing a Tree column, the editors bounds is reset. The reason we have to do this is because JTable doesn't think the table is being edited, as getEditingRow returns -1, and therefore doesn't automaticly resize the editor for us.
      Overrides:
      sizeColumnsToFit in class JTable

    • isHierarchical

      public boolean isHierarchical(int column)
      Determines if the specified column is defined as the hierarchical column.
      Parameters:
      column - zero-based index of the column in view coordinates
      Returns:
      true if the column is the hierarchical column; false otherwise.
      Throws:
      IllegalArgumentException - if the column is less than 0 or greater than or equal to the column count

    • getHierarchicalColumn

      public int getHierarchicalColumn()
      Returns the index of the hierarchical column. This is the column that is displayed as the tree.
      Returns:
      the index of the hierarchical column, -1 if there is no hierarchical column

    • getCellRenderer

      public TableCellRenderer getCellRenderer(int row, int column)

      Overridden to fix core bug #4614616 (NPE if TableModel's Class for the column is an interface). This method guarantees to always return a not null value. Returns the default renderer for Object if super returns null.

      Note: The lookup strategy for is unchanged compared to super. Subclasses which override this with a different lookup strategy are strongly advised to implement a custom StringValueRegistry with that lookup strategy to keep the WYSIWYM in SwingX.

      Overrides:
      getCellRenderer in class JXTable

    • getCellEditor

      public TableCellEditor getCellEditor(int row, int column)
      Overrides:
      getCellEditor in class JTable

    • updateUI

      public void updateUI()
      Description copied from class: JXTable

      Additionally updates auto-adjusted row height and highlighters.

      Another of the override motivation is to fix core issue (?? ID): super fails to update all renderers/editors.

      Overrides:
      updateUI in class JXTable

    • updateHierarchicalRendererEditor

      protected void updateHierarchicalRendererEditor()
      Updates Ui of renderer/editor for the hierarchical column. Need to do so manually, as not accessible by the default lookup.

    • getStringAt

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

      Overridden to message the tree directly if the column is the view index of the hierarchical column.

      PENDING JW: revisit once we switch to really using a table renderer. As is, it's a quick fix for #821-swingx: string rep for hierarchical column incorrect.

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

    • getComponentAdapter

      protected ComponentAdapter getComponentAdapter()
      Returns the adapter that knows how to access the component data model. The component data adapter is used by filters, sorters, and highlighters.
      Overrides:
      getComponentAdapter in class JXTable
      Returns:
      the adapter (defined in JXTable) that knows how to access the component data model
