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!

Constructor Detail

JXTreeTable

public JXTreeTable()

Constructs a JXTreeTable using a DefaultTreeTableModel.

JXTreeTable

public JXTreeTable(TreeTableModel treeModel)

Constructs a JXTreeTable using the specified TreeTableModel.

Parameters:

treeModel - model for the JXTreeTable

Method Detail

setSortable

public void setSortable(boolean sortable)

overridden to do nothing. TreeTable is not sortable by default, because Sorters/Filters currently don't work properly.

Overrides:

setSortable in class JXTable

Parameters:

sortable - boolean indicating whether or not this table supports sortable columns

See Also:

TableColumnExt.isSortable()

setShowHorizontalLines

public void setShowHorizontalLines(boolean show)

Sets whether the table draws horizontal lines between cells. It draws the lines if show is true; otherwise it doesn't. By default, a table draws the lines.

If you want the lines to be drawn, make sure that the row margin or horizontal intercell spacing is greater than zero.

Overrides:

setShowHorizontalLines in class JTable

Parameters:

show - true, if horizontal lines should be drawn; false, if lines should not be drawn

See Also:

getShowHorizontalLines, setRowMargin, setIntercellSpacing

setShowVerticalLines

public void setShowVerticalLines(boolean show)

Sets whether the table draws vertical lines between cells. It draws the lines if show is true; otherwise it doesn't. By default, a table draws the lines.

If you want the lines to be drawn, make sure that the column margin or vertical intercell spacing is greater than zero.

Overrides:

setShowVerticalLines in class JTable

Parameters:

show - true, if vertical lines should be drawn; false, if lines should not be drawn

See Also:

getShowVerticalLines, setColumnMargin, setIntercellSpacing

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.

Overrides:

editCellAt in class JTable

hackAroundDragEnabled

protected boolean hackAroundDragEnabled(MouseEvent me)

decides whether we want to apply the hack for #168-jdnc. here: returns true if dragEnabled() and the improved drag handling is not activated (or the system property is not accessible). The given mouseEvent is not analysed. PENDING: Mustang?

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

setRowHeight

public final void setRowHeight(int row,
                               int rowHeight)

Throws UnsupportedOperationException because variable height rows are not supported.

Overrides:

setRowHeight in class JXTable

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. Reconciles semantic differences between JTable and JTree regarding row height.

Overrides:

setRowHeight in class JXTable

Parameters:

rowHeight - height of a row

setColumnMargin

public void setColumnMargin(int columnMargin)

Sets the margin between columns.

If you set the column margin to zero, make sure that you also set showVerticalLines to false.

Overrides:

setColumnMargin in class JXTable

Parameters:

columnMargin - margin between columns; must be greater than or equal to zero.

See Also:

setShowVerticalLines

setRowMargin

public void setRowMargin(int rowMargin)

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.

If you set row margin to zero, make sure that you also set showHorizontalLines to false.

Overrides:

setRowMargin in class JTable

Parameters:

rowMargin - margin or intercell spacing between rows

See Also:

setShowHorizontalLines

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)

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

updateUI

public void updateUI()

Overridden to message super and forward the method to the tree. Since the tree is not actually in the component hieachy it will never receive this unless we forward it in this manner.

Overrides:

updateUI in class JXTable

isHierarchical

public boolean isHierarchical(int column)

Determines if the specified column contains hierarchical nodes.

Overrides:

isHierarchical in class JXTable

Parameters:

column - zero-based index of the column

Returns:

true if the class of objects in the specified column implement the TreeNode interface; false otherwise.
